Why does it say there are no available connections on the laptop? If the wireless network was working and now there are no connections available. Identifying Network Settings

Hello, Kirill!

Lack of drivers

If you saw that on WI-FI icon(ladder) or a red cross appears on the monitor icon, this may indicate problems with the driver network adapter. Very often, especially after reinstalling the system, specialists forget to install this driver because it is rarely included in the Windows builds. You can solve this yourself.
All you need is to find a disk with drivers for your laptop. If it is not available, you can download it from the official website of your PC manufacturer. Very important: from the official website, because in other places you may come across infected with viruses files.
Install the resulting driver and reboot the equipment.

After the manipulations have been performed, you need to check the result. This can be done in Device Manager. If there, on the list network devices, You see your WI-FI adapter, which means everything went well and you can connect to the network.

Checking receiver activity

Often modern models laptops are equipped with a power switch WI-FI cards. There are many cases when the user himself or his relatives turn off this switch, which leads to the absence of the network.

You can find out whether this toggle switch is active by the presence of an LED on the laptop case. Its location depends on the model and manufacturer.

If the LED is on or blinking, you need to be guided by its color:

yellow - disabled;
white, green - included.

If your model does not have an indicator, there is another option:

go to “Start”;
then go to “Control Panel”;
Find the item “Network and Internet”, and in it “Network and Sharing Center” shared access»;
click on “Change adapter settings”;
then right-click on the “Wireless Network Connection” shortcut;
select "Enable".

If after this the color of the label changes, then you did everything correctly.

Settings problem

Quite often it happens that the wireless network settings in a laptop are lost due to failures or the settings in the router are lost.

The result of such processes is a ladder icon with a yellow blot, i.e. There are available networks, you just need to enter the connection data. You need to click on this icon and select the desired network and enter the password for it in the field.

To check the status of settings on your wireless WI-FI router(if it exists), you need:

in the browser enter in address bar IP address: 192.168.0.1 or 192.168.1.1;
enter in the authorization window login admin, password admin or 1234 or leave this field blank;
make changes to the settings wireless mode and WAN mode, in accordance with the standards of your provider and save them.

If after this nothing has changed, then you can do next steps:

remove the wireless adapter from device manager and restart the PC;
Check if the WI-FI Auto Setup service is enabled. In order to do this, go to the Windows control panel, select “Administration” - “Services”, find “WLAN Auto Configuration” in the list of services and, if you see “Disabled” in its parameters, double-click on it and in the “ Set Startup Type to Automatic and click the Run button.
Check on the router in the security settings which mode b/g/n is selected. There may be a discrepancy between the router mode and the laptop.

That's all. I hope some of the advice helps you.

Best regards, Evgeniy.

The misunderstanding, which we will touch on in our article, increasingly worries users of laptops connected to a wireless network. This misunderstanding is of a technical nature - the essence of the problem is the unexpected failure of the built-in or external router receive and transmit data.

In this case, the network icon in the tray takes on a characteristic appearance - a ladder crossed out with a red cross - and when you hover over this cross with the mouse, a message appears stating that there is supposedly no available connections in Windows 7. This network behavior comes as a complete surprise to the user. We will teach you how to deal with this problem, but for now let us draw your attention to the fact that it often appears immediately after reinstallation operating system. It may very well be that the cause of the network failure is incorrect installation of drivers or installation of drivers that are not entirely suitable for your adapter model.

In this case, find out the model of your adapter and download the most suitable ones for it. fresh drivers. To do this, go to the laptop manufacturer’s website - they will probably be found there. Download and install everything that is offered to you. The fact is that in addition to the drivers necessary to ensure the operation of the network, drivers may also be required to support function keys.

Many laptops use adapter to control function keys type "Fn". If you do not use these keys, then controlling the adapter becomes a hassle. The so-called flight mode is also activated by the keys. Without installing the appropriate programs, you lose most of the functionality. No wonder that WiFi module starts to behave strangely.

First attempts to fix the problem

To get started, we can suggest trying the following:

Rebooting the router sometimes helps. To reboot, simply unplug the power cord from the outlet and plug it back in.
Call standard tool Windows diagnostics from the context menu of the connection icon.
Sometimes hardware WiFi switch appears to be turned off on the laptop panel. Check its condition.
To connect WiFi, you can try to run service utility, supplied by some computer manufacturers with drivers.
Go to the "Network connections" section of the control panel. Check if the icon is active wireless connection. If not, activate it from the context menu.
Check the drivers again.

In theory, these events should liven up your network. However, this may not happen. In this case, follow our further recommendations.

Device Manager - to help

Like any computer device, the wireless adapter is registered in Windows snap-in, called “Device Manager”. You can access the dispatcher in different ways:

Right-click on the “My Computer” icon. IN context menu select “Properties”. In the window that opens, select the “Hardware” tab and click on the “Device Manager” button.
But you can do it differently. Without further ado, call up the “Run” command window and enter devmgmt.msc in the command field – this is the name of the snap-in. The “Run” window itself is called up either with the mouse from the “Start” menu, or with the “Win” + “R” key group.

As a result, a dispatcher window will open, something like the one in the figure:

Go to the "network adapters" node.
Expand this node.
Find in its list a device whose name includes the word “Wireless” - this is the wireless adapter.
Then right-click on its name and select “Delete”.
Then go to the main menu of the dispatcher window.
And in the “Actions” item, click on the “Update hardware configuration” item.

If after this the network remains unavailable, try tinkering with the system services settings.

WLAN Auto Configuration Service

The service in question may also be responsible for the problem. It is located in the same place as all other Windows services, at the address “Control Panel” => “Administration” => “Services”. Find the “WLAN auto-configuration” service in the list and find out whether it is running. To do this, right-click on the service name and select Properties in the context menu that opens. A window similar to the one below will open:

Make sure the Startup Type field is set to Automatic. If this is not the case, then set this parameter, and then restart the service by first clicking on the “Stop” button and then on the “Start” button. Save the changes made by closing the window with the “Ok” button.

If everything is done correctly, the wireless network should become active. If this is not the case, then it is worth looking for other reasons for its inoperability - it may be the equipment itself.

Technology, especially computer technology, can sometimes behave extremely capriciously and present various surprises. Just yesterday you could use your laptop without any problems, access the Internet using a home wireless connection, receive and send hundreds of files and photos, and use social networks. And today there is no connection to the Internet, and in a place where yesterday there was not a single error in the system tray, a mysterious message is shining: “There are no connections available.” And what to do in such a situation is not entirely clear. We will try to analyze the causes of this problem in as much detail as possible and talk about the most effective ways her decisions.

First we turn to those who have encountered similar problem after buying a brand new laptop or just reinstalling Windows. If in one of these situations you see the message: “No connections available” on your laptop, then most likely there is a problem with network driver, which could easily be missing from the system after reinstalling Windows. Another reason in laptops various models The Wi-Fi adapter may be mechanically disabled. You can learn how to understand which of the two situations was the primary source of the problem in your case from the instructions below.

If a laptop running Windows reported problems with the connection extremely unexpectedly, and just yesterday everything was fine in perfect order, there may be several more problems, and we will tell you about each of them today.

Any device can experience difficulties in operation and even freeze, similar to how Windows sometimes freezes. Since the router that distributes the Wi-Fi signal is, in fact, the same computer with an operating system and processor, it can also stop working or freeze. At the same time, a working indication on its body can mislead the user and create the appearance normal operation device, but no signal comes from it at this moment.

The display on the device does not always indicate network problems

In order to return the router to normal working condition, you need to unplug it, wait a few seconds (7-10) and plug it back in. After giving the device a minute to turn on and start all systems, try again to check for available networks on your laptop.

If you receive your Wi-Fi signal directly from your provider, contact support and describe the situation, mentioning that you have no available connections. The operator will be able to remotely reboot his equipment.

The problem is with the network adapter being turned off.

Please note that many modern laptop models running Windows provide a mechanical way to enable and disable the Wi-Fi connection function. This allows you to save battery power. Find the toggle switch at the ends of your laptop case that is responsible for turning on wireless adapter, and turn it on. If such a toggle switch is not provided, then it may help you special key at the top of the keyboard with an image wireless signal. In the case where such a button is not on the keyboard, then the manufacturer has probably provided a certain key combination. Most often this is the Fn function key and the F2 or F3 buttons. This information can be found in the manual for specific model.

After mechanically turning on the wireless network adapter, try searching for available connections again.

Problem with software disabled network adapter

Also wifi adapter on your laptop can be deactivated programmatically in Windows itself. To enable it and repeat attempts to find available networks, you need to launch the Panel Windows management, go to the Network and Sharing Center, and then in the column located on the left side of the open window, click on the “Change adapter settings” link.

You will see information about all the network adapters and connections contained in your laptop. Find “Wireless Connection" and enable it using the right-click menu.

After that, also try to find available Wi-Fi networks using the system tray icon. The problem you are facing may have been resolved and then you will see an available network. But it may well happen that the adapter refuses to turn on, items in the context menu after pressing right key the mice will be inactive or the adapter has turned on, but still does not see available Wi-Fi networks. In this case, proceed to the next points of our instructions.

The problem is the driver is not working correctly or is missing.

Each function of the Windows operating system is responsible for its operation. specialized program. And it is responsible for the operation of each component in your laptop system program, which is called the driver. It is she who corrects the operation of devices, gives them system commands and monitors the correct execution of these same commands. If your system is missing a driver or has a driver version installed that doesn't quite fit your network adapter, you may also experience difficulty finding, connecting to, and transferring networks.

There may be situations in which the driver was installed, configured, and the system worked quite correctly, but after another simple reboot you saw the message “No connections available” and you cannot access the network. Your operating system probably has a program that is responsible for automatically updating and installing drivers various devices, and after a reboot, a driver version that did not match the network adapter model was installed, or test build, not yet working as desired.

To update and install drivers various components your laptop, we always recommend using the two most reliable source- the website of the manufacturer of the computer itself or the website of the manufacturers of its individual components.

Go to the manufacturer's website, download the latest version of the software for the network adapter, making sure first that it is intended for the same version of Windows that is installed on your laptop. After this, install and restart your PC. To avoid problems when installing a new driver, we recommend that you first remove the existing one by finding your network adapter in Windows Device Manager, right-clicking on its name and going to Properties > Driver > Uninstall.

After installing the latest driver and rebooting your PC, scan for available networks again to make sure correct operation all systems and for connecting to the network.

The problem is an incorrect system configuration or a violation of registry settings

When all previous methods tried, but none of them gave the desired result, you can resort to really serious and deep search malfunctions and system malfunctions. This is especially recommended for those users who are confident that before the failure, the network adapter performed its functions correctly and you did not interfere with its operation. In this case, the reason could be third party programs and applications, their installation or removal, reconfiguration of individual parts of the system. Any of these actions could not have the best effect on the network operation on your laptop, and then you should resort to the following actions.

If you have a backup of your system using specialized software, try restoring the system to the state it was in when the last checkpoint was created. This procedure will cancel everything last changes in the system and will return it exactly to the state in which your network adapter performed all its functions correctly. Please note that restoring a copy that is too old may deprive you of large quantity settings, programs and parameters that have appeared in the system recently.

If you do not have such a backup, refer to the built-in system Windows recovery, which creates checkpoints during certain key procedures performed on the computer. To do this, open “Your Computer Properties” by right-clicking on the “My Computer” icon on the desktop, and then look for “System Protection” in the column on the left in the window that opens. Click the "Restore" button and select the system state point that needs to be restored on your PC.

If system protection has been disabled and control points were not created, we recommend resorting to full scan OS and Windows file integrity check. For this there is special service, which can be launched using the command line.

Open a command prompt, manually enter sfc team/scannow and press Enter on your keyboard. If the system contains damaged files or some parts of the registry are not working correctly, the scanning service will try to detect them and restore them to their original state. This procedure may take quite a while long time, and upon completion, a mandatory system reboot will be required.

As a rule, troubleshooting problems with no available connections does not require serious skills and is rarely a reason to contact a service center. You can restore the wireless network adapter using one of the methods given here. If the desired result cannot be achieved using one of the instructions, it may be necessary to combine several methods at the same time. This depends directly on the specific laptop model, its configuration and system parameters.

A fairly common problem among owners of laptops with Windows 7 or Windows 8 (8.1) - at one point in the notification area instead of the usual wireless icon Wi-Fi connections a red cross is displayed, and when you hover over it, a message stating that there are no connections available.

Moreover, in most cases, this happens on a completely working laptop - just yesterday, perhaps, you successfully connected to an access point at home, but today this is the situation. The reasons for this behavior may vary, but general outline- the operating system believes that the Wi-Fi adapter is turned off, and therefore reports that there are no connections available. And now about ways to fix this.

If your wireless network was working and now there are no connections available

If everything worked recently and now you have a problem, try the methods listed below in order. And if these options have already been tried, go to the seventh point, from which we will begin to describe in detail (because everything is not so simple there for novice computer users).

7. Remove the wireless Wi-Fi adapter from Device Manager, install it again

To start the dispatcher Windows devices, press the Win+R keys on your laptop keyboard and enter the command devmgmt.msc, and then press Ok or Enter.

In Device Manager, open the “Network adapters” section, right-click on the Wi-Fi adapter, see if there is an “Enable” item there (if there is, turn it on and do not do everything else that is described here, the message “No connections available” should appear) disappear) and if it is not there, select “Delete”.

After the device is removed from the system, in the device manager menu, select “Action” - “Update hardware configuration”. The wireless adapter will be found again, drivers will be installed on it and, perhaps, everything will work.

8. See if the WLAN Auto Configuration service is enabled in Windows

In order to do this, go to the Windows control panel, select “Administration” - “Services”, find “WLAN Auto Configuration” in the list of services and, if you see “Disabled” in its parameters, double-click on it and in the field Set the “Startup Type” to “Automatic” and click the “Run” button.

Just in case, look through the list and, if you find additional services that have Wi-Fi name or Wireless, turn them on too. And then, preferably, restart your computer.

We hope one of these methods will help you solve the problem when Windows says there are no Wi-Fi connections available.

The misunderstanding, which we will touch on in our article, increasingly worries users of laptops connected to a wireless network. This misunderstanding is of a technical nature - the essence of the problem is the unexpected refusal of the built-in or external router to receive and transmit data.

In this case, the network icon in the tray takes on a characteristic appearance - a ladder crossed out by a red cross - and when you hover over this cross with the mouse, a message appears stating that there are supposedly no available connections in Windows 7.

Call the standard Windows diagnostic tool from the context menu of the connection icon.
Sometimes the WiFi hardware switch on the laptop panel is turned off. Check its condition.
For WiFi connections You can try to run the service utility supplied by some computer manufacturers along with the drivers.
Go to the section " Network connections» control panels. Check if the wireless connection icon is active. If not, activate it from the context menu.
Check the drivers again.

In theory, these events should liven up your network. However, this may not happen. In this case, follow our further recommendations.

Device Manager - to help

Like any computer device, the wireless adapter is registered in a Windows snap-in called “Device Manager”. You can access the dispatcher in different ways:

Right-click on the “My Computer” icon. In the context menu, select “Properties”. In the window that opens, select the “Hardware” tab and click on the “Device Manager” button.

The service in question may also be responsible for the problem. It is located in the same place as everyone else. Windows services, at “Control Panel” => “Administration” => “Services”. Find the “WLAN auto-configuration” service in the list and find out whether it is running. To do this, right-click on the service name and select Properties in the context menu that opens. A window similar to the one below will open:

In this article we will tell you about such an interesting case. Our computer has Windows 8. Specific problem arose with WI-FI.

Here we have such an asterisk on WI-FI, “no connection, there are available connections.”

We are opening WI-FI. We see an available connection. And in theory, when we click on it, we should have a connection, but we see that a circle appears that it is trying to connect and then nothing happens.

First of all, we go to the Network and Sharing Center. Click change adapter settings. And we thought that the problem was in the settings, but our settings are automatic.

Let's now try to do some troubleshooting. Then click Network adapters and click Next. We see that problems are being discovered.

The Select a network adapter for diagnostics window appears and we click Wireless network and click Next.

And we see that our problem is not fixed.

That is, the troubleshooting module did not help us at all. Nothing worked for us.

Let's now go to the control panel. This is the right one top corner– parameters - control panel.

Among the small icons we find the device manager. Click on it.

And here we see that in the device manager we have an unknown device with an exclamation mark. Let's try to remove this.

Let's now try to connect. Still nothing happens. This didn't help either.

Let's try to remove the WI-FI adapter. We take it and delete it.

Now let's try to search for drivers. Click Update hardware configuration. And he, of course, updated the hardware configuration, but now we will have to download the drivers from the website.

We came with you to the site. Now we are looking for laptops.

In the product search window, enter the brand of our laptop.

So we see that he found our laptop. Let's move on to it. And click next.

Below we see Networks and find the Ralink 802 Adapter. Load the drivers.

We see that our drivers have already been downloaded. Let's launch them.

The installation has started. Click Next. Archive it where we offer it to you, click Next.

And we see that the installation has begun.

The following window appeared:

And we click Delete all.

Removal is complete.

So, let's go to our drive C. Find required driver. And click Setup.

Click Finish. This installed the drivers. Now we need to reboot our laptop. Now we will reboot it and then see if WI-FI starts working for us.

That's it, we've rebooted. Our adapter is on fire Exclamation point yellowish. This means that the drivers did not work or there are some problems.

And we clicked Search for software online. Now he's looking for us software. Maybe he’ll find it and download it online.

That's it, the update is done. So he said that he downloaded the drivers and that now the drivers for this device do not need to be updated.

But at the same time, we still have an exclamation mark.

Let's click Properties. We see that it writes “Failed to load driver.”

Let's try installing DriverPack. We find it and launch it.

He is now checking the configuration of our laptop.

He found uninstalled drivers. Let's click install drivers if found. We see that the drivers are called the same.

We see a window “Do you want to restart your computer now?” and we click Cancel. And still we go into a reboot.

As you can see, no matter what we did, the wireless network was not configured in any way. In our case, only reinstalling Windows helped. After Windows 8, we installed Windows 7. And WI-FI now works. And there were some problems with the operating system itself.

That is, if you have the same problem, then you can safely reinstall windows. We hope everything was clear and wish you good luck.

If you have any questions, we suggest you watch the following video:

Problem with software disabled network adapter

Also, the Wi-Fi adapter in your laptop can be deactivated in the most Windows software way.

In this case, proceed to the next points of our instructions.

The problem is the driver is not working correctly or is missing.

For the operation of each operating room function Windows systems is answered by some specialized program. And a system program called a driver is responsible for the operation of each component in your laptop. It is she who corrects the operation of devices, gives them system commands and monitors the correct execution of these same commands. If your system is missing a driver or has a driver version installed that doesn't quite fit your network adapter, you may also experience difficulty finding, connecting to, and transferring networks.

The problem is an incorrect system configuration or a violation of registry settings

When all the previous methods have been tried, but none of them have given the desired result, you can resort to a really serious and in-depth search for faults and problems in the system. This is especially recommended for those users who are confident that before the failure, the network adapter performed its functions correctly and you did not interfere with its operation.

This depends directly on the specific laptop model, its configuration and system parameters.

A fairly common problem, especially common after some changes: reinstalling the operating system, replacing a router, updating firmware, etc. Sometimes, finding the cause is quite difficult, even for an experienced technician.

In this short article I would like to dwell on a couple of cases due to which, most often, a laptop does not connect via Wi-Fi. I recommend that you familiarize yourself with them and try to restore the network on your own before contacting outside help. By the way, if it says “without access to the Internet” (and the yellow sign is on), then you better look.

1. Reason No. 1 - incorrect/missing drivers

A very common reason why a laptop does not connect via Wi-Fi. Most often, you will see the following picture (if you look in the lower right corner):

No connections available. The network is crossed out with a red cross.

After all, as it happens: the user downloaded a new Windows OS, burned it to disk, copied all his important data, reinstalled the OS, and installed the drivers that were installed before...

The fact is that drivers that worked in Windows XP may not work in Windows 7, those that worked in Windows 7 may refuse to work in Windows 8.

Therefore, if you are updating the OS, and in general, if Wi-Fi does not work, first of all check whether you have the correct drivers and whether they were downloaded from the official website. And in general, I recommend reinstalling them and watching the laptop’s reaction.

How can I check if the driver is in the system?

Very simple. Go to “my computer”, then right-click anywhere in the window and select “properties” in the pop-up window. Next, on the left, there will be a “device manager” link. By the way, you can open it from the control panel, through the built-in search.

Here we are most interested in the network adapters tab. Look carefully to see if you have a wireless network adapter, as in the picture below (naturally, you will have your own adapter model).

It is also worth paying attention to the fact that there should not be any exclamation marks or red crosses - which indicates problems with the driver and that it may not work correctly. If everything is good, it should be displayed as in the picture above.

Where is the best place to get a driver?

It is best to download it from the manufacturer’s official website. Also, usually, the laptop comes with native drivers instead, you can use them too.

Even if you have native drivers installed, and Wi-Fi network does not work - I recommend trying to reinstall them by downloading them from the official website of the laptop manufacturer.

Important notes when choosing a driver for a laptop

1) Their name, most likely (99.8%), should contain the word “ wireless«.
2) Correctly determine the type of network adapter, there are several of them: Broadcom, Intel, Atheros. Usually, on the manufacturer's website, even for a specific laptop model, there may be several versions of drivers. To know exactly which one you need, use the utility.

The utility perfectly determined what hardware was installed in the laptop. You don’t need to install any settings, you just need to run it.

Several websites of popular manufacturers:

Acer: http://www.acer.ru/ac/ru/RU/content/home

HP: http://www8.hp.com/ru/ru/home.html

Asus: http://www.asus.com/ru/

One more thing! The driver can be found and installed automatically. This is described in the article. I recommend checking it out.

2. Reason #2 - is Wi-Fi turned on?

Very often you have to watch how the user tries to look for the causes of breakdowns where there are none...

Most laptop models have an LED indicator on the case that signals Wi-Fi work. So, it should burn. To enable it, there are special function buttons, the purpose of which is indicated in the product passport.

For example, laptops Acer inclusion Wi-Fi is achieved using the “Fn+F3” button combination.

You can do it differently.

Go to "control Panel" your Windows OS, then the “network and internet” tab, then “ network and sharing center", and finally - " Change adapter settings«.

Here we are interested in the wireless connection icon. It should not be gray and colorless, as in the picture below. If the wireless network icon is colorless, then right-click on it and click “enable“.

You will immediately notice that even if it does not connect to the Internet, it will become colored (see below). This indicates that the laptop adapter is working and it can connect via Wi-Fi.

3. Reason No. 3 - incorrect settings

It often happens that a laptop cannot connect to the network due to a changed password or router settings. This can happen through no fault of the user. For example, the router settings may be lost if the power is turned off during intensive operation.

1) Checking settings in Windows

First, pay attention to the tray icon. If there is no red cross on it, it means there are available connections and you can try to join them.

We click on the icon and a window should appear in front of us with all the Wi-Fi networks that the laptop has found. Select your network and click “connect”. We will be asked to enter a password, if it is correct, then the laptop should connect via Wi-Fi.

2) Checking the router settings

If you cannot connect to a Wi-Fi network and Windows reports an incorrect password, go to the router settings and change the default settings.

To enter the router settings, go to " http://192.168.1.1/"(Without quotes). Typically, this address is used by default. The default password and login are most often “ admin"(in small letters without quotation marks).

Next, change the settings in accordance with your provider settings and router model (if they are lost). In this part it is difficult to give any advice; a more extensive article on creating local network Wi-Fi at home.

Important! It happens that the router does not connect to the Internet automatically. Go into its settings and check if it is trying to connect, and if not, try connecting to the network manually. This error often happens on TrendNet brand routers (at least it used to be on some models, which I personally encountered).

4. If all else fails...

If you've tried everything and nothing helps...

I will give two pieces of advice that help me personally.

1) From time to time, for reasons unknown to me, the Wi-Fi network disconnects. The symptoms are different each time: sometimes it says no connection, sometimes the icon lights up in the tray as expected, but there is still no network...

A 2-step recipe helps to quickly restore your Wi-Fi network:

1. Disconnect the router’s power supply from the network for 10-15 seconds. Then I turn it on again.

2. I restart the computer.

After this, oddly enough, the Wi-Fi network, and with it the Internet, work as expected. I don’t know why and why this happens, I don’t want to dig into it either, because... This happens quite rarely. If you can guess why, share it in the comments.

2) There was once such a thing that it was generally not clear how to turn on Wi-Fi - the laptop did not respond to the function keys (Fn + F3) - the LED did not light up, and the tray icon wrote that “there are no available connections” (and it does not find Not one). What to do?

I tried a bunch of methods, I wanted to reinstall the system with all the drivers. But I tried to diagnose the wireless adapter. And guess what - he diagnosed the problem and recommended fixing it by “resetting settings and turning on the network,” which I agreed with. After a few seconds the network started working... I recommend trying it.

That's all. Good luck with your settings...
