The key sizes 40 bits and 104 bits correspond to WEP encryption, so the
card definitely seems to support it.
If that is true, then I see no reason for it not to be working. Can't figure out what I am missing. OTOH, could it be saying that the key I put in is the WEP type (40 or 104 bits) rather than that it supports those lengths because it supports WEP?
If I don't get any other replies, I guess I will try converting everything to WPA.
As for the security mode, from the iwconfig man pages:
"The security mode may be open or restricted, and its meaning depends on
the card used. With most cards, in open mode no authentication is
used and the card may also accept non-encrypted sessions, whereas in
restricted mode only encrypted sessions are accepted and the card will
use authentication if available."
Sounds like words that say it may mean this or it may mean something else. But, yes, I could try restricted just to see if it makes a difference. BTW, there is a big difference between the terms encryption and authentication but a lot of the wireless documentation seems to use the terms sloppily to say the least.
You can manually set the encryption keys and security mode with
iwconfig. I don't know what graphical app ubuntu uses for configuring
wireless.
