Why doesn't the tablet connect to wifi. Incorrect time and date settings. Root rights and system update

Quite often, Android users are faced with the fact that their smartphone or tablet does not connect to wifi, it says “saved”, but there is no connection. Alternatively, you should. Most often, this situation occurs due to problems or errors. Before changing settings on your phone or tablet, you need to make sure that in your router:

  • the correct region is set;
  • the correct time is set - time desynchronization will not allow the device to create a timestamp;
  • the wireless signal operating mode is configured;
  • The encryption type is specified and supported by the device.

To make sure that you are entering the correct connection data, you can view the saved parameters in the router settings. To do this, from any connected device you need to go to the browser, enter 192.168.1.0 or 192.168.1.1 into the address bar (as a rule, it is registered on the router itself). In the menu that opens, find the SSID and PSK lines.

The reason why an Android smartphone does not connect to WiFi and says “Saved” may be a change in the encryption type, SSID or password.

What to do if, when connecting to WiFi, it says “Saved”, but there is no network
Regardless of whether the device is a tablet or a smartphone, the troubleshooting methods are the same:

  • Check the router settings. What to pay attention to was described above.
  • Reboot the router. Even if the router settings are correct, rebooting can help solve the problem: the connection will appear and the system will stop reporting the error.

  • Re-create the connection on your phone or tablet. To do this, you will need to delete old data.

In general, the last point, when it does not connect to Wi-Fi with WPA2 protection, but writes saved, is quite simple:

  • Delete. You need to go to Settings, click on the wireless connections tab (depending on the version, the name may differ). Having selected the desired connection, hold your finger on it and select delete in the menu that appears.
  • Reboot the device's wireless module. After this, all available networks will be searched.
  • Pass authentication. When a network is detected, you will need to re-enter the password. If the network is hidden, then you can add the SSID yourself. To do this, go to Settings - Wireless connections - Additional settings - Add new. In the window that appears, you need to write the name (SSID), security protocol and password.

These instructions should help if WiFi does not connect on your phone and it says “Saved” and “Without network access.”

After purchasing a tablet, you will most likely want to use wireless connectivity. Often, users find themselves in a situation where the device does not see the network or displays a number of errors when connecting. In this article we will look at the most common problems that arise when accessing the Internet and ways to solve them.

Why doesn't my tablet connect to the wireless network?

1. Entering the wrong password

The most common reason for wireless Internet failure on a tablet. Most often it occurs if the user has changed the password, but the Android device has never connected to it. Enter a new password and check if your device connects to the Internet.

2. Viruses

Sometimes the reason why your device won't connect to the Internet can be due to malware. To fix this problem, you need to scan the gadget with an antivirus.

3. Power failure

Inexpensive routers are characterized by unstable operation. Voltage surges can lead to the tablet not seeing the network. To solve the problem, reboot the router by disconnecting it from power for 2-3 minutes. Then turn it on again. Sometimes a reboot needs to be done several times.

4. Wrong encryption type

To check the encryption type, go to the router settings. To do this, enter the router's IP address in the address bar of your browser. This data can be found on the device sticker or in the instructions. In the tab that opens, select “Advanced settings”. Then, under Wi-Fi, click Security Settings. To view the encryption type, go to the “Network Authentication” menu. From the proposed options, select WPA-PSK\WPA2-PSK2 mixed. Reboot your router. 5. Time and date settings are incorrect

In some cases, the tablet does not connect to the wireless network due to incorrect date and time values. After correcting these parameters to the correct ones, network operation will resume.

6. Checking the MAC filter mode

Another reason why a user on a tablet does not see Wi-Fi may be changes in MAC address filtering settings. To exclude this option in the router settings in the “Wi-Fi” section, go to the “MAC filter” item. Check which mode is selected. The following values ​​are possible:

  • Disabled – by default, there is no restriction for MAC addresses.
  • Allow – access to the wireless network is allowed only to those devices whose MAC addresses are registered on the corresponding tab. Other devices are not allowed to access the Internet.

Deny – there is a list of MAC addresses that are restricted from accessing the Internet. If the router sees a prohibited MAC address, it closes the Wi-Fi connection for this device.
If the “Allow” or “Deny” modes are selected in the router settings, check whether the MAC address of your device has access to the wireless network. Or change the mode to Disabled. After these manipulations, check how the gadget connects to the network.

7. Channel diagnostics

If the tablet sees the network but does not connect to it, check the channel matches. This problem occurs when the signals of two routers operating on the same channel intersect. There is interference that prevents access to the wireless network.

Check on your tablet to see if there are other wireless networks nearby. If your neighbors have Wi-Fi, then perhaps your routers operate on the same frequency.

To change the channel in the router settings, go to the “Wi-Fi” section to the “Basic settings” tab. Find the “Channel” line, try choosing a different value.

Reboot your router.
If the channel is set to “Auto” mode in the settings, the router itself will search for an available free channel and use it. Therefore, in most cases it is recommended to use this mode.
8. Changing Wi-Fi version

The reason why the tablet does not see the wireless network may be that it does not support the wireless version that is installed in the router settings. On the “Wi-Fi” tab, go to “Basic Settings”. In the “Wireless mode” line, enter 802.11b\g\mixed. In this mode, the router provides Internet access for all types of devices.

Connecting a tablet to Wi-Fi in most cases does not cause any problems: in the corresponding section of the electronic gadget’s menu, the required point is selected, a password is entered, and Internet access is opened. Along with this, in some cases, connecting to a wireless network becomes impossible for a number of different reasons. After reviewing the information below, you will learn why your tablet may not connect to Wi-Fi and what to do to resolve any problems.

Important note! The root of the problem in the vast majority of cases lies in the settings of the router or the tablet itself, and very rarely the lack of connection is caused by the inoperability of the built-in Wi-Fi module or a temporary shutdown of the router.

Incorrect time and date settings

It is extremely rare that problems with connecting to Wi-Fi occur due to incorrectly set time and date. Start looking for a way out of this situation from this moment. Open the settings section of your tablet and go to Date and time. Set the correct settings and try connecting to Wi-Fi.

If everything is fine, congratulations. Wi-Fi connection not working? Continue reading the instructions.

Password problems

A fairly common case: the user decided to set a different password to connect to Wi-Fi, but forgot to make the appropriate changes to the tablet settings. The device will try to connect to the Internet using the old password and, of course, it will not be able to do this.

To solve the problem, go to your Wi-Fi settings, delete the old profile and try connecting again.

Software settings failure

Connection problems may occur due to a software glitch. There is a good service utility - Wi-Fi Fixer. You just need to download it and install it - no additional settings are required.

The main page provides information about the current connection status, and the Known section provides information about Wi-Fi points to which the tablet has ever been connected.

Restart your device and try connecting to Wi-Fi again.

Incorrect tablet settings

Failures in some settings may result in difficulties connecting to Wi-Fi. The fastest, most effective and drastic way to solve the problem is to reset the settings.

Attention! Before resetting, be sure to back up the required files and contacts - everything will be deleted.

In Settings, open the “Backup & Reset” tab.

Select Reset Settings.

Review the proposed system information, confirm your intentions, and then try connecting to Wi-Fi again.
Presence of malicious software

Those who claim that Android is virus-free are mistaken. There are viruses, but most of them are not large-scale malicious programs that make the device’s operation completely impossible, but so-called. “minor pests” that make incorrect changes to some functions.

Download the application (Antivirus for Android). Launch and scan your device for malware. If you find suspicious files, follow the application's instructions.

WiFi router settings

Quite often, problems connecting tablets to Wi-Fi arise due to incorrect router settings. Do the following:

Go to your device settings. To do this, connect to the router via a wireless connection or cable (you can from a computer, laptop, any smartphone or tablet, etc.). You will find connection recommendations in the instructions specific to your router. In most cases, to do this you need to enter 192.168.0.1 in the address bar of your browser;

Go to “Wireless Settings” (the name may differ depending on the brand and model of the router). Make the following changes: “Mode” - “11bgn mixed”, “Channel” - “Auto”. Next, open the MAC Address Filtering tab and select Disabled.

Have you tried all the above methods, but still can’t connect to Wi-Fi? Most likely, the problem is in the tablet's radio module. In this case, you need to contact a specialized service center with a request for diagnostics and repairs.

Hi all! As I already said, I work as a sys. I am an administrator at an Internet cafe, and naturally I understand computer equipment and local networks.

So, recently my Aunt called me and asked me to come set up the D-link wi-fi router that she had just bought in the store. I arrive, set it up, everything is fine. Aunt is happy. Surf the Internet on a netbook via Wi-Fi

But it was not there! The next day he calls and says the phone doesn’t see wi-fi and the laptop doesn’t see wi-fi! It only finds some neighbors’ access points and that’s it, well, I come, I think, let me check the router at home, I take it home and connect it. Everything is ok, everything works! I'm shocked =) I come back to Auntie and connect it again, it doesn't work... So I went to a friend and it worked for him too... Then I started rummaging through the settings of the router, but I couldn't find anything.

Then my Uncle comes into the room and says there is a security company downstairs, maybe their equipment is blocking them? I think for sure! The problem is there, you won’t see Wi-Fi Aunt And I’m leaving...

But a few days later 1 more person called me with the same problem! And after a long time I found a solution to this problem! In this article I will now explain step by step how to solve this problem!

Nowadays, a Wi-Fi router has appeared in almost every apartment, and when you turn on the router in a neighboring apartment, your Wi-Fi Internet may disappear (everything will work fine through the cord in the computer).

Solution

I’ll show you the example of a wi-fi router D-link DIR 300

The problem was that when setting up the router, the Wireles channel is selected by default automatically (auto), shown in the screenshot:


We need to go to the router (web interface), if you did not change the local IP address when setting up the router, then it remains the default 192.168.0.1 , write this IP in the browser and go to the router’s Web interface.

We go to the item as in the screenshot and change the channel, set a number different from the one set automatically (I always got it the first time and everything started working).


In this article we will talk about such a common problem, what to do if the tablet does not connect to a wireless WiFi network. This is a hot topic today, as tablets are widely used all over the world. In addition, problems with connecting to wireless networks appear quite often and not everyone is able to solve them on their own.

So, when talking about a wireless network, you should understand that we are talking about a WiFi router or other access point. It is worth noting that for security purposes, such connections require entering a key. This means that the first thing you should do if your tablet does not connect to the WiFi network is to check that you entered the password correctly.

Why doesn't my tablet connect to WiFi?

As mentioned above, the most common mistake is an incorrectly entered password.

However, there are other problems related directly to wireless equipment and its settings. These include the following:

  • A MAC filter is installed in the router settings.
  • The router is malfunctioning.
  • Encryption type mismatch.
  • Channel mismatch.

It’s worth noting that you don’t need to configure anything on the tablet itself. Everything that can affect the connection is contained in the router settings. This is where we will go to troubleshoot problems. And first of all, you should pay attention to the fact that budget routers such as TP-Link, D-Link. Asus, Zyxel and so on are not highly stable. They have a tendency to freeze.

This can happen for many reasons, for example, due to power outages, heavy load (if you download large amounts of information at high speed), as a result of connecting a large number of subscribers, and so on. In any case, you should reboot the router. How it's done. It's simple. Unplug the device from the power supply and wait 7-10 minutes, then turn it on again.

Checking the encryption type

If the tablet does not connect to the WiFi network and says “Saved,” this indicates a mismatch in encryption types. First of all, you should know that modern WiFi devices support the WPA-PSKWPA2-PSK2 mixed encryption type. If you select a different mode on the router, then the tablet is easy to connect to. In other words, the tablet sees the WiFi network but does not connect to it.

So, we need to go into the router settings. To do this, we connect to it using a laptop (via WiFi or via cable). Next, open any browser and write the router’s IP in the address bar. The necessary data is available on the device itself or in the instructions. If you do not have a manual or there is no data on the router case, then open the command line. To do this, simultaneously press the Windows + R keys, in the window that appears, write CMD and press “Enter”.

In the menu that opens, write the IPCONFIG command and press Enter. Now you need to find the line “Default Gateway”. This is the data we need.

As a rule, this is 192.168.0.1, but depending on the router model, these values ​​may differ. So, we enter the received data in the browser, after which the system will ask you to enter your login and password. We write admin, admin respectively.

Here we are in the router settings menu. It is worth noting that the interface may differ depending on the device model. There may also be differences in the names of some sections. Let's consider further actions using the D-LinkDir-615 router as an example.

In the router settings at the bottom of the screen, click the “Advanced settings” button. We find a section called WiFi. Here we click “Security Settings”. Here the first line “Network Authentication” is the encryption type. Select from the suggested options WPA-PSKWPA2-PSK2 mixed and apply the changes. After this, reboot the router.

Often a similar error occurs when the authentication type is correctly set. In this case, rebooting the router will help you. As mentioned above, budget models are not stable in operation.

Checking the MAC filter

The answer to the question why the WiFi network on the tablet does not connect lies in the MAC address filtering settings. The fact is that to increase protection, a special function is enabled that determines the physical address of the computer, opening or closing access to it. To check this, go back to the router settings. In the WiFi section, select "MAC Filter".

To avoid problems in the future, you should turn off filtering.

But if you don’t want to do this, then we do the following. First, let’s look at which mode is selected:

  • Allow – the router allows access only to the specified devices.
  • Deny – the router blocks network access to the specified tablets.

Now all that remains is to find out the physical address of your tablet and check if it is on the list and, if necessary, add or remove it.

Checking channels

If you have turned off filtering, but the tablet still sees the WiFi network, but does not connect to it, then you should proceed to the next step. This problem often occurs due to channel mismatch. So let's go back to the router settings and try to change them.

To do this, return to the main page of the access point settings and in the WiFi section, select “Basic settings”. Here we need to find the “Channel” line. Try changing it to something else. It should be noted that it is recommended to set the mode to “Auto”. Thanks to this, the router will automatically use the most suitable channel.

What should you do if you have tried all the above steps but still cannot connect your tablet to the WiFi network? Try rebooting not only the access point, but also the tablet itself. Quite often, various glitches occur in mobile devices. After rebooting, try connecting again.

Wireless mode

Don't forget about wireless versions. Very often, the answer to the question of why the tablet does not connect to the WiFi network is the fact that it simply does not support the version of wireless communication that is installed on the router. The fact is that today there are several versions of Wi-Fi communication:

  • 802.11n.
  • 802.11g.
  • 802.11b.

At the same time, as a rule, the router supports all these standards, which cannot be said about the tablet. So let's go back to the router's settings menu and check which mode is set. Open advanced settings. Next, in the WiFi section, select “Basic Settings”. In the “Wireless mode” line, select 802.11 b/g/n mixed.
