I've obtained an AR5413 based NIC and it seems happy. I bet your area is just very congested. Hopefully at some point I can get the OK to release the spectral scan code, which means you can turn your AR9280 into a spectrum analyser, then you can see how noisy things are. > =A0And what about channels? All these HT/20 and HT/40 -- what is best? Well, you can just choose a HT/40 channel if you'd like to test interoperability. 11n and 11bg clients can associate, but there's currently no HT protection of frames to interoperate with legacy networks so performance may suffer. But yes, it'll work. So if you'd like to try HT/20 or HT/40, give it a shot. It'll at least be a good test to see what breaks. :) Adrian
