Cannot see my wireless network via Broadcom card

Hey guys,
I have a gateway notebook that has a broadcom 802.11g wireless card, and
until a few days ago I was able to see my wireless network for a good month.
My broadcom card seems to be working fine, but i went ahead and uninstalled
it, reinstalled it, tried updating the driver and everything seems to be in
good order. I can hook up the notebook directly to the router and it sees
the lan, i also hooked up a wireless linksys card to the notebook and it
sees the network wirelessly this way, but the broadcom card itself will not
see my wireless network. I do have another wireless laptop and that can see
my network, so I think i have eliminated anything being wrong with my
router. Does anyone have any solutions to rectifying this problem? It
would be most appreciated. Thanks in advance.
