I’m a new Lumia 920 user , and i thought this might help some of you who’s having the same problem as me.
So recently my phone couldn’t connect to my house wifi , which is quite troublesome for me. After searching around the net i finally found the fix for it , and it works!
First just connect to your D – Link control panel via 192.168.0.1 (using a computer that is connected to LAN cable) . Username would be admin while password just leave it blank.
Next go to wireless setup . It’s on your left.
Then go to Manual Wireless Connection Options , click Manual Wireless Connection Setup.
Go to Wireless Network Global Settings, and un-check the Enable Auto Channel Selection option.
Change the Wireless Channel to 11.
Save the settings, restart your computer, and TA-DA ! Wifi is back.
