alpha rt-n firmware releases

[bef]

I use it like this:
Internet <--utp cable--> [RT-N16] < - - - - WiFi - - - - > [WL-500W] <--utp cable--> [asus oplay]
This gives me a bandwidth of 40Mbits/s

I'm trying to setup a more or less identical system, but i'm currently stuck with the rt-n16 <-> wl500w wifi bridge... what settings are needed on the wl500w? and do i understand it correctly that only wpa and not wpa2 enryption works works for this setup?

regards
