Hello helpful mindful mac people, i have finally set up a dsl airport network, using an airport express and an airport extreme. i have them set up for wds. when i put on wireless security, say 128 bit, the macs get in just fine but the pc does not. it asks for a five character password, and i try it in 40 bit wep but then the whole network doesn't seem to work. any suggestions? thanks, r.
