Hi,

If your wi-fi channel is set to Auto, try setting it to a fixed channel between 1 and 11. Avoid the extra channels 12 and 13 that are available in some regions.
If you have a hidden SSID, make sure you enter it in exactly the same case as it is on the router, check for capital letters.
If your password is very long, or has unusual punctuation characters in it, try changing it for a shorter, simpler password.
Having spaces in the password (eg "1234 5678") may cause problems, try removing the spaces.
Check with the router supplier's website to see if there are any firmware updates.
If you go to the settings page (Home --> Menu --> Settings) and type 711 (hold alt and type UQQ) you will get the "711 Page" which has diagnostic information about the wi-fi connection.

Hello,



1. Restart your Wi-Fi connection on your device. Swipe down from the top of the screen and tap Wireless, and then tap Wi-Fi. Next to Wi-Fi, tap Off, then tap On.



2. Restart your device. Press and hold the Power button for 40 seconds or until the device restarts automatically. If your device restarts automatically before 40 seconds have passed, release the Power button. If your device does not automatically restart after 40 seconds, press the Power button to turn it on.



3. Move closer to your router. From your device, check if you can connect to your Wi-Fi network. If your network does not appear in the list, tap Scan from the Wi-Fi menu. If you still do not see your preferred network, you can add it to your device.



4. Use Channel 1-11. Your wireless router is set to use a Wi-Fi channel from 1 to 11. If you provide your wireless router, or the router manufacturer, for additional help.



5. Restart your router and modem. Unplug your modem and router, wait a full 30 seconds, and then plug the modem into. After your modem turns on, plug in your router and wait for it to turn on.
