My brand new Nokia Lumia 920 cannot connect to my wifi.
It keeps saying that I type the wrong password, which i do not.
All other devices in my house connect just fine.
I have tried switching channel on my router and change from WPA PSK to WEP but nothing helps.
Try disabling the encryption completely on your router and see if it works. Will indicate if it is an encryption issue or or transmissio settings. Also try other routers and see if you have the same issue.
Another thing you can try is to check your router for updates and install if available.
I'll link to another discussion that had a resolution that worked for me. This is the only place I saw a resolution for the problem.
Basically, I changed my router settings from mixed 802.11 b/g to 802.11 g only. Now it connects, no problem.
