MN 820 WEP Sync on Windows 2000

I have had this working fine for a month until tonight. I
rebooted my laptop and haven't been able to reconnect.

My Adapter Settings are tryng for 64-bit WEP, and I have
the same code information for both base and laptop... and
on top of that, the Adapter Settings box shows
a "Connection Status" of "Connected," but of course the
Broadband Network Utility is telling me there is no
signal, I'm not connected, Internet and Network
unavailable.

I have reset, reinstalled, and changed channels repeatedly
with no real change - what does it take to get the Adapter
Settings dialog box to agree with the Broadband Utility
Screen and show tht I am connected? I'm not in an area
where I've ever been knocked offline before since
installing.

Thanks!!
