Netgear Wireless Router Problem

I have the router/ PCMCIA card combo and Verizon DSL.
I spent hours on the phone to Netgear awhile back. There
was a conflict between the router and modem IP addresses, as
I understood it. This was corrected and the problem seemed
to be resolved.
All was resolved until yesterday when I had no wireless
again. The direct Ethernet connection between the
router and the computer worked fine, but the wireless
doesn't work. I made no changes in settings.
Before I go through the agony of another call to
Netgear, does anybody have any ideas?
Thanks.
