Why doesn’t WiFi connect?

Wireless Internet is a fairly new technology, which in a short time has gained immense popularity among billions of users around the world. Wi-Fi technology allows you to connect all compatible devices within a radius of about 50 meters to your access point and exchange data at speeds up to 150 Mbps. In addition, there is a more modern version of this standard, which supports speeds of up to several gigabits per second.

All modern smartphones and laptops are equipped with Wi-Fi radio modules, this allows not only to save significant costly traffic of mobile operators, but also allows you to view high-quality multimedia content without prior download. In order to use this technology, you need to connect Wi-Fi on a laptop or smartphone, enter a protective password from the network and save it for future use.

Why isn’t Wi-Fi connected on a smartphone or tablet?

In some cases, when connecting to a wireless network, problems may arise that will make the Internet unavailable on your tablet or smartphone.For example, if the router settings are incorrect, your gadget may not even see the network.

If you set up Wi-Fi at home, but your smartphone or tablet does not see the network, then follow these steps:

  • Try to restart the router and the device you want to connect to it;
  • Go to the “Settings” section on your smartphone, select the “Networks” item, open the “Wi-Fi” section and see if your router is in the list of available networks;
  • If after clicking on the desired network, you are asked for the password from it, then enter the password that was set on the router, then the device will have to connect to the network;
  • If the network is not displayed, then try restarting the module by turning off and re-enabling the Wi-Fi network;
  • In some cases, it is necessary to adjust the settings of the router (such as communication channel, frequency and network mode) so that it can work correctly with your device.

When trying to connect to the network on your tablet / smartphone, the message “Saved WPA \ WPA2 protection” is displayed, the problem may lie in the incorrect encryption settings on the router or in the incorrect password entered on this network:

  1. Check that the password is entered correctly. To do this, open the connection, click “Change”, check the “Show password” box under the password field and re-enter it;
  2. If the first option did not help, then the problem is in the settings of the router:
    • First of all, read the instructions for your gadget and read what network modes (for example, 802.11 b / g / n), as well as the types of data encryption (WPA / WPA2 or WEP) it supports;
    • Go to the settings of the router, to do this, type in the address bar of the browser IP-address and press the "Enter" key, then specify the administrator's login and password (the default is usually admin login and the same password);
    • Go to the menu item that is responsible for configuring the wireless mode;
    • Here you will see several different settings, experimenting with which you can achieve the desired result;
    • First, set the network mode that your smartphone supports, you must select it from the drop-down list in the appropriate field (most devices support mode 11b, but it has a lower range and data transfer rate);
    • Be sure to specify the correct location of the router (your country);
    • In the “Channel width” section, it is best to choose a frequency of 20 MHz (as a last resort, you can set the “Auto” mode);
    • In the item responsible for channel selection, set the value to “Auto” or select No. 2 / No. 8;
    • Now save the settings of the router and reload it.

After all the above operations have been done, your device should connect to the network. It is worth noting, perhaps, after changing the settings, you will have to connect your computer to Wi-Fi again, since it will not be able to independently find the network with the changed parameters.

Connection issues due to encryption settings

In almost any network, the default is to register a client with a password. However, if you select WPA / WPA2 and AES encryption, some devices may not connect to this network. To connect such a device, on the router you need to change the authorization method to WEP, it is less secure, but it is supported on almost all devices. For this:

  • Go to the settings of the router as described in the previous section;
  • Go to the “Wireless Network Security”;
  • In it, select the WEP item and enter the key that will be used for authentication (identification of the user by the router);
  • Click on the “Save” button and restart the router.

After that, you will need to reconnect all your devices to Wi-Fi, since they will not be able to recognize this network on their own.

What should I do if the sites do not open after connecting to Wi-Fi?

In such cases, you can try to adjust the additional settings of the wireless network:

  • Open the settings of the router;
  • Go to the advanced Wi-Fi settings;
  • Set transmitter power to maximum;
  • Set the fragmentation threshold and RTS to 2346;
  • DTIM make the minimum (closer to 1);
  • Interval specify about 1000;

By slightly correcting these settings, you will again be able to open sites that could slow down and not load.
