If something is better than nothing - using the inbuilt WEP, and configuring a 128 bit key can take less than 2 mins.... OK - so it isn't perfect, but you gotta start somewhere...
I personally don't have a CCNA, or other Cisco network credential, but if it is a home wireless network - how to setup the WEP from the access point / or Ad-Hoc, is usually documented fully. (was in mine I have setup....)
But yes - I am technically minded, and I did think it was easy to read. Taking the option of "OK - it works - lets leave it" would probably be the option taken by most "Non- techies".
