WEP Key Missing

I try to sync my network settings with my main computer
base station and my wireless laptop, and I get an error
saying my Network settings floppy doesn't have the WEP key
setting. I have WEP turned off, and even when it does have
the settings, it gives me the same error.

This network has worked in the past, and only started not
working today. Does anyone know what I could be doing wrong?

Both are HP computers.
