If RT5370 works for you I would stick with it. RTxxx chips with rt2800 driver are capable to support up to 190 stations with HW encryption and 11n aggregation (something that you are not interested). Theoretically more stations can be added and those should fallback to software encryption and frame aggregation will not be done, but I'm not sure if anyone test that. I'm also not sure if many people test 11b, perhaps 11g would be better choice. BTW, what kernel version are you using (I'm curious if 11b still works on latest kernels) ? Stanislaw
