OK, I apologize in advance if I am asking a question that has been answered. I did look for the solution, but couldn't find it.

I updated my N9 to PR 1.3 a few days ago using Nokia Suite and now I can't get my N9 to connect to my home wireless router. I can connect to T-Mobile 3G no problem, and I can even use the wifi hotspot app to tether the N9 to my laptop. But the N9 will not connect to my router. I have entered the WPA key very carefully and am sure it is not a type-o causing the problem. I have also deleted the connection from the N9 and re-entered it.

I am not fluent in Linux or MeeGo, so please tell me in English what I have done wrong and/or how to fix it. Thank you and sorry for the inconvenience.
