The freeware WEP crackers say they only need 100k packets or so to get started.
While it is easy to spoof a MAC, I think that this would really only be a
problem if the attacker knew something about your setups- there's a lot of
possible MACS to try before he could even talk to your server successfully
WEP or no.
hmm...
Although if you are being sniffed and the MAC address is visible of a valid
user either after (presuming WEP use I guess) WEP is broken, I guess it is
pretty trivial- and the MAC would be visible from the start, with no WEP.
So I guess it really doesn't mean much, like a lock, it's there to keep
honest people out.
