Two trivial notes.  If you use WEP you may not want to use any automatic
utility an access point or something comes with to change a password
into a key since some of these are inherently flawed in there
generation.

Secondly, WEP does add a little to the packet overhead.  I myself live
in the country where someone would literally have to sneak a laptop up
fairly close to my house to do anything, in which case one definitely
has other problems requiring policeman.  I'm certainly not recommending
anyone avoid encryption on a wireless link, its just sometimes physical
boundaries are adequate as they are for wired ethernet.

Now if you wanted something much more secure you could take a look at my
phd project on my web page.  The test code there only works on cards
that use the orinoco drivers right now though.  There has been
insufficient interest to make it work in general.  To be honest, most
people do not need that level of security anyway.  

Of course moving away from WEP into WPA would definitely be a good idea
if you live in a non rural area, since WEP is well not so hot.
