How to distribute mobile Internet from a smartphone via Wi-Fi? Set up an access point (Wi-Fi router) on a phone with Android OS

I have already promised several times to write detailed instructions in which to tell and show, using a real example, setting up an access point (Wi-Fi router), on phones that run on the Android operating system. If I'm not mistaken, then on all Android smartphones, it is possible to distribute mobile Internet via Wi-Fi to other devices.

If your phone is running pure Android, then most likely this feature is called "Access point". On HTC smartphones (I have one), this function is called “Mobile wifi router”.

What is this chip, and how it works, I think you already know. If not, then I'll tell you in a nutshell. You can turn your Android phone into an access point, such as a mobile Wi-Fi router. You can distribute the Internet from your smartphone to other devices, such as a TV, tablet, laptops, other smartphones, etc.

That is, the smartphone will take the Internet that your provider provides you and distribute via Wi-Fi. What is it, I think, understood. A very useful feature, given that mobile Internet is not very expensive now, and operators provide quite normal tariffs.

What will we need?

The Android phone itself, configured and working Internet (if websites open in the browser on your phone, then everything is OK), well, and the devices that you will connect to your smartphone. I, on HTC, can connect a maximum of 5 devices at the same time.

I will show on the example of HTC One V. I will connect the ASUS MeMO Pad FHD 10 tablet, and a laptop. If you have a different phone, for example, Samsung, LG, Lenovo, etc., then it's okay, the setup process will not be practically different.

Setting up the distribution of Wi-Fi “Access Point” on Android

First of all, turn on the mobile Internet. So that at the top, on the notification panel, the corresponding icon appears.

There we choose " Wi-Fi router and USB modem” (may also be “Access Point Connection”). In the next window, click on " Router settings” (or Change Wi-Fi Hotspot”).

• Router name (SSID), this is the name of our Wi-Fi. We indicate any name in English letters.
• Security, and leave WPA2.
• Password. This password will be used to connect to your network. Minimum 8 characters. English letters and numbers.

We specify all these parameters, and to start the Wi-Fi router, put a tick next to “Mobile Wi-Fi router” (Wi-Fi hotspot). Tips for connecting devices will appear, just click Ok. On the notification panel, an icon should appear that the router is running.

Everything, you can connect our devices to Wi-Fi.

Connecting devices to the created access point on an Android smartphone

Turn on Wi-Fi on the tablet (for example), go to the list of available networks, see the network we created on the phone there, and select it. Enter the password (I have it 11111111), and press To plug.

Everything, you can open sites.

We connect the laptop

Also, select our network, and enter the password for the network.

The connection is established, the network is connected and with Internet access.

You can connect a TV to Wi-Fi by following these instructions:.

You can see on your phone how many devices are already connected. Just click on the button User management“. True, you will not see any useful and interesting information there.

To disable the mobile router, simply uncheck the corresponding item.

Afterword

As you can see, everything is very simple and convenient. This scheme works quite stably. (if the network is good). Do not forget that a running mobile router decently drains the battery, which is not a strong point of Android OS devices anyway.

In this article, we will talk about typical problems when connecting your phone to a wireless Wi-Fi network, among which the most common are Android freezing on “obtaining an IP address” or an authentication error when connecting. Less common, but more common, is when your Android phone or iPhone just can't see the Wi-Fi network.

In step-by-step instructions, the following variants of the problem will be considered in order and what to do in each of the cases.

• Authentication failed (or phone says Saved WPA/WPA2)
• Getting an IP address indefinitely on Android
• The phone does not see the Wi-Fi network

Wi-Fi Authentication Error on Android

If your Android phone or tablet says “Authentication failed” when connected to Wi-Fi, or says “Authentication” for a while, then it still does not connect to the wireless network (when the android says Saved WPA / WPA2 - this is usually the same situation) , then in most cases it's the Wi-Fi password, and the problem can occur even when you enter it correctly (but, of course, this is what you should first check, this article can help, you can also just look at router settings).

But it's not always a matter of incorrect input: it happens that you are guaranteed to enter the password correctly, but the authentication error still occurs.

The first thing to try here is:

1. Delete the Wi-Fi network (forget) in the phone settings, try to connect to it again by entering the password.
2. Reboot the router (unplug it and plug it back in).

If none of this helps, go to the router settings (any of the router setup instructions on this site will help, they all start with how to go to the router settings), and then to the Wi-Fi network settings and try the following ( after each change, save the settings, delete the previously saved network on the phone and try to connect again):

If even these items do not help, make sure once again that the Wi-Fi network security settings in the router settings are set to WPA / WPA2 (Personal) authentication, and not some other type (this option should be supported on any android phone). Also sometimes changing the network mode from b / g / n or auto to 802.11 n only or 802.11 b / g helps.

Android constantly writes Obtaining an IP address and does not connect to Wi-Fi

The second most common problem with connecting a phone (specifically Android) is endless attempts to connect with the text "Obtaining an IP address."

What can cause the situation:

1. The DHCP server is disabled in the router settings.
2. Just an android glitch.

If you don’t know for sure about the first point, then for a start, just restart the router, maybe this will already solve the problem. If that doesn't work, then the next steps are:

• Check if DHCP is enabled on the router, if not, enable it.
• If it is enabled, but still "Obtaining an IP address", then try to set a static IP address on the phone.

And now more about how to do both.

To enable the DHCP server, you need to go to the router settings (any instruction for configuring D-Link, Asus, TP-link, Zyxel routers begins with a description of how to enter its settings) and make sure that the DHCP server is enabled (usually , there should just be such a mark): on almost all models of routers, this option is located in the LAN or LAN (local area network) section:

• On ASUS routers - LAN - tab DHCP server
• On TP-Link routers - Advanced settings - DHCP settings
• On Zyxel Keenetic routers - In "Home Network" - Networking, for the DHCP option, enable "Server". Or, on Keenetic Lite, in Home network - Segments, check whether DHCP is enabled.
• On D-Link - in the "Network" or "LAN" section, the item or tab "DHCP server"

The second option is to set a static IP address on Android, for this:

Save your settings and try again to connect to the Wi-Fi network from your phone.

Android phone or iPhone does not see Wi-Fi network

If your phone does not see the desired Wi-Fi network, but it sees other networks, then in most cases the problem is in the Wi-Fi channels used. The fact is that by default in the router settings in the wireless network settings, it is usually “Region: Russia” and channel: auto, which forces the router to select channels from 1 to 13. But: some devices do not support channels greater than 10. (On this topic there is a separate instruction :)

Thus, the first thing to try is to go to the router settings in the wireless network settings and change one of the two:

• Region - put USA, supported by almost all devices, only 10 channels.
• Change the channel manually (set within 10).

After that, save the settings and check if your phone sees the network now. If this did not solve the problem, then it makes sense to also try changing the channel width in the router settings, and for older phones, also try changing the network mode to 802.11 b / g.

Fix WiFi connection issues

If you're having Wi-Fi connection issues, such as using Wi-Fi authentication or staying connected, try the solutions below. For example, try these steps if there is an exclamation mark on the Wi-Fi icon on your Pixel or Nexus device screen.

To check if each solution works, try opening a web page on your device.

Tablet won't connect to Wi-Fi: Authentication failed

Step 1: check settings & restart

1. Make sure Wi-Fi is turned on. Then turn off and on again to reconnect. Learn to.
2. Make sure airplane mode is off. Then turn it on and off again to reconnect. Learn to.

Press the power button of your device for a few seconds. Then click "Restart" on the screen. (If you don't see "Reboot", hold down the power button for about 30 seconds until your phone starts up.)

Step 2: Find the type of problem

• device

Try connecting to the Wi-Fi network using another device, such as a laptop or a friend's phone. If other devices are able to use the network, the problem is most likely with your device.

Check if your device can connect to another Wi-Fi network, such as a friend's house or a public network. If your device is able to connect elsewhere, the issue is most likely network related.

If your device connects to a Wi-Fi network but you still don't have internet, the issue is most likely related to your internet connection.

Step 3: Troubleshoot by Problem Type

device

1. Click InternetWi-Fi network name.
2. Click Show password.

Removing a Wi-Fi network from your device

1. Open the Device Settings app.
2. Click InternetWi-Fi.

2. Click InternetWi-Fi.
3. At the end of the list, click Add network.
4. If necessary, enter the network name (SSID) and other security information.
5. Click Save. Enter a password if necessary.

The problem may be from the downloaded application. To find out, restart your device in safe mode.

1. Turn on safe mode. Learn to.
2. Try to connect to the Wi-Fi network again.

1. Open the Device Settings app.
2. Click InternetWi-Fi network name.

Most likely, the downloaded application is causing the problem.

1. To exit safe mode, restart your device.
2. Delete recently downloaded apps one by one. See if the connection is working.
3. After uninstalling the app that is causing the problem, reinstall other apps.

There is probably a problem with the Wi-Fi network or Internet connection.

internet & network

If your Wi-Fi router and modem is yours, try turning it off and on again.

1. Unplug the router and modem power cords from the wall outlet within 15 seconds.
2. Plug the power cords back in.
3. Make sure all cords and cables are securely fastened at both ends.
4. Wait a few minutes for the lights on the modem and router to work correctly. (See the user manual for the device or the manufacturer's website.)

If the lights are not working correctly, you may have a problem with your modem, router, or internet connection.

Contact your network administrator or your Internet Service Provider. For example, the service might fail, or they might need to reset the connection.

Public networks, such as cafes or airports, often have a web page for you. If you do not complete this page, the public connection will not work.

To sign in to such a page, please sign in or agree to the terms.

If you don't see such a page after connecting to a public network:

• Check the notification that asks you to sign in.
• Open a new page in a new window.

If these steps don't work, try restarting your network connection:

1. Open the Device Settings app.
2. Click InternetWi-Fi.
3. Press and hold the network name. Click Forget the network.
4. Queue Wi-Fi and then turn it on again.
5. Tap the network name in the list.

Not all mobile service providers work with mobile hotspots.

If you have problems, please contact your carrier. Ask if your device can connect to mobile hotspots and if they are on your data plan.

How often did you need the Internet on your device, but it let you down and flatly refused to connect to an available Wi-Fi network? If not often, then once it happened to everyone. Today, the RosKase online store will tell you about the main problems in this area and help you figure out why your phone is not connecting to Wi-Fi.

Consider the main problems when connecting to a wireless Internet network:

the device connects to a Wi-Fi network, but in fact nothing is loaded;

• in the connection status line, the inscription “Connecting ...” or “Obtaining an IP address ...” does not disappear, and the device itself cannot connect to the network you need;
• authentication error or unchanged status "Authentication ...". As a rule, after this error, the status “Disabled” appears - and the device does not connect to the Wi-Fi network;
• "Saved, WPA\WPA2 security" error.

Before embarking on more complex methods for solving these problems, try the simplest method known to everyone since the very beginning of the era of high technology - reboot. As the modernized version of the folk proverb says, "Seven troubles - one reset." You can also try to remove the battery from the smartphone, and then insert it back and start the device. It may well happen that the problem will be solved by itself.

If these simplest methods did not give any results, well, proceed to the following steps.

Now we will analyze each error in detail and tell you, how to connect wifi on tablet or smartphone.

First of all, try restarting the Wi-Fi distribution source itself - the router. Perhaps there was some kind of failure, which will help to cope with the reboot. If this simple step does not bring any results, proceed to further instructions.

Problem Solving Option #1 - Changing Router Settings

Your device has successfully connected to the network, but nothing is loading? The problem may be in setting up the router if you are doing this for the first time on your device. Make sure the router is sharing internet. To do this, try connecting another gadget to it. If he remains deprived, then you should carefully study the settings of the router. On the WAN (or Internet connection) tab, check that the specified connection type matches the one provided by your ISP (dynamic IP, static IP, etc.). Depending on the type of connection, additional parameters should be specified (password, login, DNS, IP). These settings are also provided by the ISP.

It happens that the provider binds to the MAC address of the computer. In this case, after connecting the router, this address does not match - and the Internet does not work. If you have this exact situation, connect the router to your PC (whose MAC address is specified in the settings) directly via a network cable. In the router settings on the WAN tab, click "Clone MAC Address". Save the settings and reboot the router.

Check that the settings of the network/wireless adapter are the same as those of the router. Otherwise there will be a conflict - the Internet will not work. If you did not turn off automatic DNS and IP acquisition, then everything should work.

To change the settings, open "Network Center" - "Change adapter settings". If the connection to the router is via cable, then you can right-click on "Local Area Connection" and select "Properties". In the window that opens, select "Obtain IP automatically" and "Obtain DNS automatically". We save the settings.

Problem Solving Option #2 - Channel Change

If you used to connect to your Wi-Fi network without problems, but today you suddenly couldn’t do it, try changing the channel. To change it, go to the tab "Wireless network" in the router settings - and select another channel there(Channel). After saving the changed parameters, you should reboot the router and try to connect again. If nothing worked the first time, try selecting the next channel and repeat all the steps again.

Problem solving option number 3 - deleting the connection

A fairly simple and often effective way to restore the network is to delete the connection. To do this, on your smartphone or tablet, select the network, click "Delete", and then try to connect to it again.

Problem Solving Option #4 - Password Verification

If your device gave you an "Authentication ..." error, you should check that the entered password is correct, as well as the security settings. If you have already entered a password, then this item will not appear until you delete and try to connect to your network again. Enter the password carefully when reconnecting. If it's still not the case, set the security type to WPA2.

Problem solving option No. 4 - changing the operating mode

When the message “Saved, WPA \ WPA2 protection” appears, you should check the speed / mode of the wireless network (Wireless) in the router settings, since the smartphone may not always support the mode of operation of the router. You need to set the mixed mode to auto(b/g/n) instead of n, g or b.

If this method does not help, try changing the encryption type (WPA-PSK, WPA/WPA2). Enter a new password of at least 8 characters. Do not forget to save the settings and reboot the router, specifying a new password when connecting on your smartphone or tablet.

Problem Solving Option #5 - Changing the Channel Width

You can also try changing the width of the channel. As a rule, in the settings you can choose: Auto, 20 MHz, 40 MHz. Then: Saving - Reboot - Checking the performance.

Consider how to turn a smartphone into a router using the HTC One V as an example.

First of all, connect the mobile Internet. Then go to the settings in the "Wireless connections and networks" section, click on "More". You will see the "Wireless networks" window, where you will need to select "Wi-Fi router and USB modem". In the window that opens, select "Router Settings" and enter the following data:

• router name/SSID - Wi-Fi network name - specify any (in Latin letters);
• security - leave WPA2;
• password - set a password for the Wi-Fi network - from 8 characters (Latin letters and numbers).

All the same parameters must be specified to start the Wi-Fi router, check the box next to the “Mobile Wi-Fi router” item. After that, an icon will appear on the panel that the router is running. Now your smartphone works as a Wi-Fi router and can distribute the Internet.

The special program Virtual Router Plus (or Virtual Router) will help you with this. It will allow you to access the Internet from your device by turning your laptop into a router. A prerequisite is that the PC must be connected to the network via a cable or USB modem.

When the program is installed, enter the following data:

• network name SSID - give the name of the network you will distribute;
• password - enter a Wi-Fi password of at least 8 characters;
• shared connection - select the type of connection through which your computer is connected to the Internet.

After entering the data, start the virtual router. Now you can connect via Wi-Fi to your network from other devices.

Often users are faced with the problem of why the smartphone does not see Wi-Fi. The point here is not in the settings of the smartphone, but in the settings of the router. Once again, carefully check all the parameters, reboot both devices. If the data is entered correctly, then the network should show up.

We hope that all our tips have helped you connect to the Internet via Wi-Fi - and have a good time wandering around the world wide web.
