Personal hotspot for Android. Creating an access point on Android. Setting up an Android device as a router

Using your Android smartphone as a source of Internet access on a computer or tablet, of course, it is less preferable than a cable or Wi-Fi from a router, but there are times when setting up an access point on your smartphone can really come in handy.

For example, if your ISP has problems with the Internet, having a hotspot can save you if you have important work, or if you just can't live without memes anymore. 😉

In this article we will look at creating a point Wi-Fi access for Android, that is mobile point access using your Android phone.

Attention: Not all tariff plans allow you to use a Wi-Fi hotspot for free. Please check with your operator.

Setting up a mobile hotspot on Android

There is nothing complicated here. By the way, if you stock Android or something similar to it, you would have probably noticed the “Hotspot” button on your device. Moreover, it landed in the “Quick Settings” section in the notification shade.

Although the button in quick settings- The fastest and easiest way to turn your mobile hotspot on and off on Android, you'll want to set everything up before using it.

Go to your main system settings.
Click the "More" button
Open "Tethering and Hotspot"
Tap Mobile Hotspot Settings.

Enter network name. It is also called SSID, and it will be visible to everyone around you.

Select security type. WPA2 PSK is highly recommended, but you might not want to choose it at all if you just want to share the Internet with someone nearby.

Now enter password. This is the password you'll need to enter on all your other devices, and give to friends and family if you ever let them connect.

Great news: the hard part is over, now you just need to turn on your access point. You can do this right here in Settings, or you can use the button in the notification bar.

Make a hotspot through the app

On Google Play Store there are many great apps, through which you can do the same. But keep in mind that starting with Android 4.2, Google changed its security policy on this matter, which can make it difficult to use apps without Root access. For correct settings access points Wifi is better Just use the functions built into Android.

It is also important to remember security when using a Wi-Fi hotspot. You trust the access point you created for yourself, but if you connect to other networks, we recommend taking a closer look at a VPN.

Completion

OK it's all over Now! This is how you create a point Android access. As we mentioned at the beginning, the best and easiest way to do this is to use the built-in Android tools. But some of you will find this inconvenient.

Do any of you have other methods you prefer to use? Let us know about it in the comments!

Many smartphone and tablet users Android platform know that they can be used to distribute Wi-Fi. Moreover, this network can provide access to the mobile Internet. But quite often a problem arises when Wi-Fi distribution does not work in Android.

Why is distribution not working?

There could be several reasons:

FireWall blocks this feature.
A virus or some application is affecting the settings wireless network.
Operating system failure.

First option assumes that you have an antivirus installed on your device. Its security system may block such functions. In this case, simply remove the antivirus. As a rule, in most cases this is main reason, which causes an error to occur during operation Wi-Fi distribution on Android.

If this doesn't help, then move on. Second option- this is the work of someone third party application, which can make changes to the configuration of the wireless connection or a virus. While finding a virus is quite easy, detecting an application that affects network settings is much more difficult.

In the first case, simply install an antivirus and scan your smartphone or tablet. How to properly check Android for viruses is described in detail. In the second case, you need to remove applications one by one that are, in one way or another, related to Wi-Fi connection(scientific poking method). If this does not help, then you should move on to more drastic measures - a general reset or firmware.

Also, sometimes Wi-Fi distribution on Android works, but without Internet access. Here, the first thing you should do is make sure that you have turned on the mobile Internet. This is done in the settings. Open the “Mobile data” item and simply check the appropriate box. On older ones Android versions the required item may be called “Packet data”.

Also often the ability to access the mobile Internet is affected by incorrect setting networks. To set it up, you just need to call your operator’s support service and ask to send automatic settings. They come in the form of SMS. All you have to do is confirm their use.

Troubleshooting OS problems

Quite often, many problems, including the fact that Wi-Fi distribution does not work in Android, arise due to a malfunction of the operating system. First of all, you can do . It is worth remembering that after such a reset you will lose all data on internal memory devices. Therefore, it is better to save everything important on your computer first.

To perform a reset, go to settings and go to the " Accounts" Here, select “Backup and reset”. Next, simply select "Reset data" and follow the on-screen prompts.

In rare cases, the error may be hidden in correct operation firmware. Such problems may arise if you rooted your device and got into the system archive, deleted important file or changed developer options. Sometimes, in especially rare cases, a failure occurs on its own for inexplicable reasons.

Before taking your smartphone into service center, just try updating the software.

Enter system settings. Go to the “Options” tab and find the “About device” item. On older versions of Android, simply go to the bottom of the menu and select the specified section. Here you will find the Software Update category.

Every user sooner or later is faced with the fact that for some reason Wi-Fi does not work on the phone. This article is intended to help identify the sources of these common problems and find the fastest and most effective method their elimination.

Malfunction wireless communication, as a rule, caused by several reasons:

Incorrect Wi-Fi settings.
Errors in the operation of the router itself.
Wrong specified parameters mobile device.
Action malware or antivirus software.

Below we will look at each item in detail and formulate recommendations for troubleshooting. All of the following is true for Wi-Fi on Android phone, iOS, and for other operating systems.

Troubleshooting

You can cope with the problem only if you accurately determine its cause. To do this, you do not always need to contact specialists. Many errors that concern, for example, parameters wireless mode, you can identify it yourself. If the Internet slows down or works slowly, this may be due to third-party factors: for example, network overload when many gadgets are connected to it. Sometimes slow Wi-Fi is a reason to check the computer itself or the communication line of your Internet provider.

Incorrect Wi-Fi setting

First of all, you should pay attention to how the Wi-Fi access point is configured. To do this, you need to access the router menu through a browser: but you will need to enter address bar a series of symbols, the combination of which is individual for each device. Typically this data is located on back side router, look for the Login and Password lines, they will be needed in the next step.

Enter your username and password. If you managed to gain access to the menu, first of all you should pay attention to the wireless mode parameters. There are a few simple options here:

Channel - Auto, but you can try setting a different channel.
Mode - 11 bg Mixed, but changing the parameter to 11 bg only can give a positive result.
Channel Width - auto.
The transmission speed, if any, is set to the maximum value.
Region has little effect, but theoretically it can be a source of malfunction.

If everything is configured correctly, but the Internet still does not function correctly, you should contact a service center or look for the problem elsewhere, for example, by contacting your ISP. The device may be technically faulty, so it is recommended to check it immediately after purchase.

Router settings

You should check whether it is possible to access the Internet at all. If she doesn't exist, what about personal computer, and from another device, it is advisable to check whether the router itself is turned on and whether it is working correctly. Indicators signal this.

The power indicator should be green. Next to it is a system indicator that should blink. The next indicator, WLAN, shows whether wireless is enabled on the router itself or in its menu. Next are numbered LAN ports, to one of which a cable must be connected. Ideally, it should also blink. After them usually comes WAN, the indication of which indicates that the router is connected to the Internet.

In some cases, reconnecting helps.

Incorrect time or date

Wi-Fi on a mobile device may not function well due to such a small thing as wrong date- this is one of the first on the list of common causes of Internet problems. You just need to go to the time settings section and set the correct values. It is important to take into account the time zone correctly.

Wi-Fi password error

Other possible reason- password. If the phone connects to the hotspot automatically, this error occurs when the user changes the password. In other words, the password has been changed, but the gadget itself “does not know” about it and automatically enters the old one. The solution, again, is simple - create the connection again and enter the correct password.

Malware and antivirus programs

Viruses that the smartphone has “caught” on the network can also interfere with the correct operation of Wi-Fi. If you suspect an infection, it would be advisable to install antivirus program and conduct a check. There are many such programs, but they usually use established brands like Kaspersky and ESET Nod.

The other side of the coin: antivirus and others protective programs, for example, a firewall, can themselves be a source of problems. The antivirus creates a kind of “shield” to filter traffic, which sometimes affects communications. If after removing the anti-virus software the connection works correctly, in this case you will have to try another software or abandon it.

Software glitches

Many users experience wireless connection problems due to incorrect operation software. For example, when the user installs alternative firmware or any other interference is carried out with the factory characteristics of the software.

Problems with the Android system are also indicated by other errors in the operation of the gadget - constant, systematic freezes, random shutdown and others.

In this situation, you can do a Hard Rest - it will return the system to factory settings.

If the problem is with the phone's firmware, this will help solve it. But you need to know that “non-native” firmware is not deleted in this way.

When the source of incorrect operation lies in the router, you often just need to reboot the router. This is not always easy to do, since some models are not equipped with an on/off button.

If the device itself does not have a reset function, you can simply unplug the cable for 10-30 seconds.

It can also be done through the device menu. The procedure for entering there is described above. This method This is relevant if it is difficult or impossible to get to the router itself. "Reboot" option in different models routers is located in different parts menu, but usually in the system settings tab.

If the error in Wi-Fi operation is due to software glitches, you can try rebooting the device. In addition to the standard “Restart”, there are several more radical and thorough methods:

Through the menu: “restore and reset”.
By entering the number *2767*3855#.
Through Recovery Mod- it can be called by simultaneously pressing “Home”, “Power” and volume down. Next, select the “Wipe data” section.

Ask a question to a virtual expert

Conclusion

Issues with the functioning of Wi-Fi, as a rule, can be resolved easily and without the involvement of specialists. But it is worth remembering that independent technical intervention can damage the machine to the point of complete loss of functionality. If connection difficulties are not resolved accessible ways, it is better to contact the service center.

To distribute the Internet from a smartphone, it is important to know how to set up an access point on your phone. Without it, connection is not possible, but thanks to the instructions you can do this as quickly as possible. Let's give simple ways For popular models smart devices.

The first and most important thing to find out is what an access point is in a smartphone. This is a device that provides wireless internet connection for other devices in the nearest radius.

What characteristics should a smartphone meet? Android based, iOS or Windows so that it can be used instead of a router:

Availability of Wi-Fi module.
Built-in 3G or 4G/GSM module.

There is also a separate category of mobile phones, where the above modules do not exist, but OTG technology is present. They can be used as Wi-Fi distributors, but only after connecting a USB modem to it. Before connecting, you should make sure that the software on the devices is compatible.

To make a Wi-Fi access point, you should find out whether the device has an internal modem or whether it is possible to connect an external one to it, and only then proceed with the settings. We type the gadget model into a search engine and look at the characteristics.

Creating an access point on Android

To distribute Wi-Fi from Android, you need to configure the access point:

Open the device settings, click on “Demon wired networks" and further".
Open “Modem Mode”, then “Access Point”.
Select “Configure”, enter the name under which the network will be detected, select protection, enter the password and save everything.

Important! The minimum password length for wpa2 is 8 characters. It is not recommended to set the date of birth, otherwise strangers will be able to connect to the access point, because it is hacked using special programs in 3 minutes if the password is weak.

If Wi-Fi does not turn on on Android, the reason for this may be a malfunction of the module. In this case, the network icon will be gray and cannot be moved to another position.

There are other reasons why Wi-Fi does not work:

Inappropriate firmware.
Software glitch.
Infection of the system with a virus.
Incorrect password entered.

Instructions for iOS

If you can only use the router at home, but elsewhere you need high-speed wireless connection, you can use your iPhone as a router. How to set everything up:

Go to settings, select “Cellular”.
Open “Data Settings” and go to “Data Transfer”.
In the APN field, enter the information provided by the cellular operator, fill in the username and password fields.
We reboot the device, go to the settings again, activate the modem mode to use the created network.

In addition to Wi-Fi, you can use Bluetooth as a wireless network:

We create a pair between a PC and an iPhone.
On the device, click on “Create a pair” and enter the code shown on the PC.
We connect to the iPhone from a computer.

Instructions for Windows Phone

To distribute Wi-Fi from your phone to Windows based The following instructions are suitable:

Open the panel " Quick Actions", select "Hot spot" long tap(staying on the window for 1-2 seconds).
Select “All Settings” and “Wireless Networks”.
Go to point APN configurations, enter the data from mobile operator, come up with a name and password.
Save.

For Sumbian

On this moment becoming less and less relevant as the Sumbian platform fades into oblivion. To provide an Internet connection on gadgets, you can use various programs. For example, the Joikuspot application, which has very useful features:

Internet connection via WLAN.
Ability to provide multiple connections at once.
HTTPS protocol support with encryption.
Select any suitable connection point.

Possible problems

The most common problem is a malfunction of the external modem if it is used for connection. There are other factors that affect the connection:

Incorrect network settings. They need to be clarified with the operator.
Module failure. Wi-Fi icon will gray. For replacement, it is recommended to contact a specialist, do-it-yourself repair may make the situation worse.
a lack of Money On account. If you don’t have regular HSPDA Internet, you won’t be able to use a mobile phone instead of a router until your balance is topped up.

Conclusion

Setting up an access point on Android, Windows Phone and iOS allows you to use devices based on the systems presented above instead of a router. This is sometimes necessary when you need to provide a wireless connection on a PC or laptop, but no free network Wi-Fi for connecting, or while traveling. The procedure is performed once, after which you just need to activate the modem mode and use the Internet.

WHEN IS A SMARTPHONE CONVENIENT AS AN ACCESS POINT?
HOW TO CREATE AN ACCESS POINT BASED ON A SMARTPHONE?
WHAT ARE THE LIMITATIONS WITH THIS CONNECTION METHOD?

When a smartphone is convenient as a hotspot

Overwhelming majority modern smartphones and communicators are equipped with support for high-speed mobile Internet via 3G networks (in the future - LTE). Taking into account the fact that the cost of a data transfer service now tends to average communication costs (and will continue to get cheaper), and the devices themselves are available to almost anyone, using the phone itself as a modem to access the Network is practical and inexpensive. I will consider the main cases when such a work scheme is relevant.

Firstly, the smartphone as an access point replaces the 3G modem, which is usually “tied” to the network of only one cellular operator. This means that without unlocking you will not be able to use a SIM card from another provider in it - this is relevant, for example, for travelers and those who prefer to have several SIM cards, choosing them for specific tasks (one operator works better in a particular place, another provides free packages traffic when you reach the minimum paid traffic per day, the third allows you to get a discount). Of course, a universal modem is also suitable for such purposes, but if you already have a smartphone and the intensity of calls is not very high, then you can change the same SIM cards in it.

In addition, a number of devices support two (or even three) SIM cards, which is not possible for any of the 3G modems.
Secondly, a smartphone as an access point can save money if connecting to other wireless or wired communication networks is paid ( typical example: airport or train station, hotel, conference room). As additional option distributing the Internet from a phone may be relevant if the speed and security of other networks is low (for example, one open network Wi-Fi, to which several devices are already connected and which is subject to traffic bandwidth restrictions).
Technologically, the distribution of the Internet through a smartphone with a 3G module looks like this: an additional connection is created from the existing network connection with the server of the mobile Internet provider, through which traffic passes to the connected equipment - laptop, tablet, game console, another phone. The smartphone itself becomes a DHCP server that distributes access to other devices via a NAT connection.
Equipment that requires Internet access can be connected to the smartphone either via USB or Wi-Fi. There is also a less common option for distribution via Bluetooth. In the case of Wi-Fi and Bluetooth we're talking about about the creation virtual network, and it is advisable to restrict access to it with a password.
How to create a smartphone-based access point
I will show you how to create an Internet access point using the Google Phone as an example. This mobile OS was chosen due to its prevalence on smartphones and the simultaneous coexistence of several software versions that provide different functions. For the purity of the experiment, I’ll take Motorola model Atrix 4G under Android control 2.3.4 and will configure it to distribute the Internet via Wi-Fi.
As is known, in operating system GoogleAndroid distribution mode wireless internet was not officially supported until the summer of 2010, when Android 2.2 came out with the corresponding standard function. Users resolved issues with accessing the Internet by installing additional software and updating Linux kernels in the system, having previously gone through the procedure of obtaining root rights. In version 2.2 and higher, the connection mode works for USB and Wi-Fi - the corresponding items are available in the “Settings” - “Wireless Connections” menu.
However, I cannot use this standard option. Firstly, it has an extremely meager number of settings, and I do not have the opportunity to set, in particular, the maximum Wi-Fi power transmitter and adjust throughput channel, plus set adequate security parameters. Secondly, you cannot “share” the Internet on the Motorola Atrix 4G if a SIM card from an operator other than the American AT&T is inserted into the phone. This limitation is due to politics. cellular companies prohibit unauthorized distribution in order to protect the network from overload and increase revenue from the service - if you pay additionally for the option of distributing a certain amount of traffic, the operator will enable this function.

For this reason, I can distribute the Internet using third party program. I chose Open Garden Wi-Fi Tether. This small application helps you organize a Wi-Fi and Bluetooth hotspot from your phone. In order to use it, you need to gain root access to the device. Then the application needs to be found and downloaded from Android Market(it's free). When starting, you need to open the settings and set several parameters:

enable Network protection (Enable WEPEncrypition) to avoid unauthorized connections access point - telephone;
change the access key (Change Passphrase) - specify a new 16-character (preferably) combination of characters for authorization. After this, on the main screen, click on the animated Wi-Fi network icon with the caption Start Open Garden WiFi Tethering and wait for the network connection to be created and established. On the connected equipment in the list available Wi-Fi networks you need to select a network with called Android Tether and connect to it.

What are the limitations with this connection method?

I chose the option of distributing the Internet via Wi-Fi as the most convenient option available, and I did this for several reasons. Firstly, this way you can connect several devices to the Network at once (since, naturally, only one connection is possible via USB). Secondly, the smartphone is not directly connected by wire
with a connected device - it can be put in a pocket or window for best reception signal, and sit down with your laptop in a convenient place. Thirdly, the number of conflicts with existing network connections(if the connected device has already been configured with wired networks) minimized: here the process is performed in the usual way to a hotspot via Wi-Fi, as if it were happening in a cafe or airport, to a public Wi-Fi networks or visiting friends to their router.

However, I note that the access point organized using the Wi-Fi capabilities of the phone operates exclusively in ad-hoc mode, and not in the “infrastructure” mode used by conventional Wi-Fi access points. In addition, with a high degree of probability, only computers, tablets and some mobile devices, supporting ad-hoc connections.
Game consoles for the most part only work in point-to-point mode, so their control software will also have to be modified to provide access to the Network. Another disadvantage of distributing the Internet via Wi-Fi is that the battery drains very quickly. I solved this problem simply: I put the phone on charge.
