Wireless not working on laptop

[Chickadee]

Hi All

I have a Dell Inspiron laptop running windows vista that for some reason has decided that is doesn't want to connect wirelessly to the BT homehub. It was working and then suddenly stopped.

Wireless is on! but is just will not connect. Does anyone have any ideas? Laymans terms please!

If you need more info please advise and I will provide.

Thanks

Just a point, but doing the above will totally reset the router, clearing the username and password from it and probably resetting it back to having no security on the wireless.
