I recently received a thomson st780 router free with my o2 broadband package. I set it up with my desktop with an ethernet cable, and now i can connect to the internet etc no problems.

The problem is that when i try to connect to the router wirelessly with my laptop, i always find the router but sometimes i cant connect, and other times i can but then the internet wont work.

Hopefully someone is familiar with this problem and can help me fix it.

cheers
