Help My Ray will not connect to my WiFi

[Jamies]

Hey
My Xperia Ray use to connect to my Wifi with no problem but now it wont.
When I go to the settings > Wireless & Networks > Wifi settings and try to connect to my router it it says remembered below the router name. No matter how much i click connect nothing happens (My Wifi is turned on) Does anybody know what is wrong, I can connect anything else to my router but not my phone.

(I am using a BT home hub 3

Something to try, unplug power from router wait a second the reconnect power. keep any eye on the phone and you should see that it connects to the router again once it is broadcasting signal. If this does work then I would advise you log into the Market with the phone and download an application called Wifistatic. Once this is downloaded open it and hit the "Add Configuration" option and accept the auto configuration, this should stop this problem from happening again.
