Broadband internet

Group,

I installed wireless G MN820 and it worked fine for about
two weeks. During a thunderstorm I turned off the
computer inproperly. After turning the computer back on I
was not able to connect to my broadband interned with my
desktop computer. However, my laptop is able to connect
to the internet with no problems. I have followed all the
instructions available but no luck in getting my desktop
to connect to the net. Any advise or guidance in what to
do next.
