WIRELESS CAN'T CONNECT TO BASE STATION

I am using Microsoft Broadband Networking Wireless Base
Station | MN-700. It stays connected to the internet with
no problems. My problem is my wireless connection. It
was working fine one day and then the next day its says
no signal. What happened? When I rebooted the computer
and opened the broadband utility, there for a split
second, it showed a signal and then it went away and
displayed no signal. Nothing new was added to the house.

Any suggestions?
