I re-itterate... "which we all know is worse than no security at all, right?"


while I'm sure we have had this discussion before, WEP is bad because it gives 
a false sense of security... 

128 bit WEP can be trivially broken within an hour or 2.  quicker for 
particular implementations with implementation flaws, etc.
48 bit within minutes.

the information transmitted can be recorded encrypted and then broken later - 
including password /username pairs, bank account details, whatever... no need 
to get an hours worth of traffic, there are other weaknesses that allow 

so, secure your network properly. starting with individual machines. denigh an 
attacker a logon and they can't really do much can they? implement IPSEC on 
wireless connections, ssh, etc. 

or put up with some attacks.  e.g. rate limit your uplink, etc.
