Mobile Internet, despite the assurances of providers, is not available everywhere, and you want to save money: mobile traffic is organic on most tariffs. Therefore, going into a cafe or restaurant, to the station, to the airport waiting room, we first of all start looking for free WI-FI. Yes, and returning home, we try to turn off data transfer as soon as possible and connect to a router that distributes wired Internet to several devices. But sometimes the usual scheme fails and the phone does not connect to WI-FI for no apparent reason. Wherever such a nuisance happens, we will help you understand the reasons for the collapse and tell you what to do in order to return to the world of the big Internet at good speeds.
How to connect your phone to a public Wi-Fi network
Open public networks sometimes become a real salvation when the phone suddenly announces a boycott of the mobile Internet and persistently draws the EDGE icon, putting an end to plans to rummage around in social networks, watch movies, read the news. In this case, you should look for affordable and free WI-FI networks. They are available at all airports, most restaurants and cafes, at railway stations and parks, and even in the metro – not only in Moscow. In order to connect to such a network, it is enough to select the appropriate option in the largest number of “sticks” showing signal strength. Networks are divided into open and password-protected. In the second case, the code phrase can be asked from the staff, unless, of course, this network is intended for visitors.
How to connect your phone to your home Wi-Fi network
In order for the phone at home to be able to connect to the wireless network, you need a router. It can be a laptop or a computer with a WI-FI adapter. The main advice: do not be lazy to put a high-quality password on the network and connect the WPA2 protection type. You should not strive to be a good neighbor, this is fraught with many problems from ending traffic to problems with the law if a dishonest person connects to your network.
It is enough to set up the connection once, in the future the phone will automatically find the home network.
Android phone does not connect to Wi-Fi: causes and solutions
Trite, but still sometimes it happens: check if the router is turned off, if the WI-FI icon is lit on it, if all cables are tightly in the sockets, if the phone is switched to airplane mode. If everything is in order, check what kind of connection problem is occurring.
1. Wi-Fi is connected, but it says “no internet access”
There are several reasons.
- The router is really not connected to the network at the moment or is working with errors. It needs to be rebooted – you can ask the staff about this if we are talking about a restaurant or cafe. Or do it yourself: we recommend unplugging the power cord for 2-3 minutes, at the same time checking whether the Internet and ethernet cables fit tightly into their cells.
- You are too far from the router, and it simply “does not reach” your device. Try to move. If it happens at home, put the router in another place – perhaps some kind of obstacle interferes with signal transmission.
- You have not completed the network connection. In many public networks, a mandatory requirement is user authentication on a special page that comes out after you click on the “connect” button. You may have prevented the page from opening. In this case, find the network in the list of available ones, click on it and select “Delete”. Connect again and wait for the start page to open, where you will need to enter your phone number and the password that will come to it. If the page does not open automatically, go to the default browser installed on your phone and try to open any page – an authorization window should appear.
- The date and time are incorrectly set on the phone. Check the settings, enter the correct data.
- There are problems with the IP address. Go to the list of networks and click on the one you need with a long press. Select “Change Network”, then “Advanced Settings”. Here, in the IP setting parameter, set the value to “custom” and enter 192.168.1.X (where X> 1) (make sure that this data suits you by looking at the label on your router. Its IP address will be indicated there. Phone address there will be the same numbers, except for the last one – choose it to your taste.)
- It is possible that despite the free network, the Internet is distributed only to the IP / MAC addresses of devices defined by the administrator, i.e. You won’t be able to connect without getting to know the administrator.
- Perhaps the connection is blocked by a “protective program”: firewall or antivirus. Try turning them off.
2. The phone does not connect to Wi-Fi, but the computer is connected
This suggests that the problem is not in the router or provider, but in the device itself. Although, the communication channel may be clogged and the router simply does not pull a large number of devices. Try turning off the Internet on your computer or laptop and connect only from your phone.
The easiest way to solve the problem: restart the phone. If this does not help, delete the network. To do this, go to the list of available WI-FI, by long pressing the screen next to the name of your network, call the list that opens and click the “delete this network” button (option: “forget network”). Together with it, all settings will be deleted: remembered IP address, DNS and other parameters. Then find the network you need again and connect to it by entering the password.
If this does not help, find the item “Reset mobile Internet settings, WI-FI, Bluetooth” in the “Settings” of your phone. It can be located in the “System” section or in the “Additional functions”. Reset your settings, restart your phone and try to connect again.
All in vain? Download an antivirus application on your phone and check it. Malicious software can intentionally block access to the Internet or break access due to certain settings.
3. Writes “saved”, but there is no connection, authentication error
If you are trying to connect to a public network in a restaurant or airport, for example, then the explanation can be very simple and offensive to you: the connection limit on the router has simply been exhausted, it cannot cope with the number of devices attacking it, eager to get into the network. This often happens in crowded places: at holidays, concerts. Any channel has a limit, and it can be hard to feed the phones of thousands of insatiable users. Or an old router is installed and the phone simply does not support its settings. It is difficult to solve the problem in this case, it remains to wait or look for another network.
Also, a public network can be protected by a password and you do not know it or enter it incorrectly. Try to talk to local employees, maybe they will reveal the secret to you, even if it is not a public network for all customers.
If we are talking about a home network, this error may indicate a hang of the router. In this case, it can be revived by simply holding down the reset button or by turning off the power for a couple of minutes.
If the error persists, go to the router settings through the computer (by entering the IP address of the device in the address bar of the browser), check that the WPA-2 encryption type is selected, and the DHCP server is enabled. And yes, make sure that the password is entered correctly – on the router and on the phone. Even if it seems to you that you remember it by heart and there can be no problems in this. Sometimes, during the typing process, an error may occur and you will not even know in which character: just change the password and try to access the network again.
Also check the date, time and region settings on your phone and router. Mismatch can result in devices blocking each other.
4. Writes “getting ip address, ip configuration error”
This problem, which occurs not so rarely, suggests that your router cannot communicate with the mobile device in any way. Moreover, the problem can be both in the router and in the phone.
First of all, without further ado, just reboot the router: take out the power cord for 2-3 minutes, turn it on again.
If this does not help, then manually register IP on the phone. Finding out what to write is not difficult: look at the label on the router, this information is there. To enter the settings, go to the list of networks, delete the existing connection. Click on the connection again, but do not enter the password, but select “advanced settings”. Click on “IP settings” and select the custom sub-item.
In the “Gateway” field, enter the address of the router (for TP-Link 192.168.1.1). In the line IP-address – the same numbers, but change the last one to any from 2 to 999.
As a DNS, many experts recommend putting addresses from Google 8.8.8.8 or 8.8.4.4. – they are suitable for devices based on Android, in which almost all applications are based on this system.
Then enter the password and click “connect”.
The third method is to check that DHCP is enabled on the router. It is possible that during the upgrade process or a failure, these settings were removed and now the devices simply cannot reach the router. In order to enable the mode, you need to go to the router through a browser by entering the IP address of the device in the address bar. Then log in and select the DHCP item, it can be in the “Advanced Settings” menu, the “Network – LAN” or “Local Area Network” submenu. At this point, you need to click “Yes” in the line “Enable DHCP server.
If none of these steps help, and other devices easily connect to this network, check your phone for viruses, reset your internet settings, or if all else fails, reset your phone to factory settings. Be careful – this operation will delete all information from your phone, write it to another medium in advance or make a backup copy.
5. The phone does not connect to WI-FI automatically
Check that the “Automatically connect to WI-FI” item is enabled in the “Settings” of the phone. Just keep in mind that this constant searching for networks can cost you a battery. Also, “Auto-connect” must be made active directly in the settings of the network you need.
