Wireless Card Problem

I'm trying to set up my wireless network again (the MN-
700) after taking it down for awhile and now that I've
tried to re-set it up, my wireles card wont connect with
my network. My base station works fine but the wireless
card says during setup that my floppy disk doesn't have
the right information to connect to any of the networks,
even though the only stuff on the disk is the information
I got from my base statio. Even if I manually enter the
information I get the same message. Any ideas?
