What is the weakness of WEP, and the likelihood that somone will
actually crack my 128-bit WEP? I ask because several years ago I went
to the trouble of setting up airsnort on Linux and attempting to crack
my (at the time) 40- or 64-bit encryption. (details here:
http://www.davewilson.cc/Wireless/Airsnort.html). I wasn't able to
crack WEP with my ordinary network traffic; I had to set up four
simultaneous ping sessions with very large packets, after which it took
about 50 minutes. In actual use I don't think my network sees enough
traffic to provide enough interesting packets to Airsnort to crack it.
And that is with 40-bit. I have not tried it with 128-bit.
