>From ifconfig.c I gather that (nr->nr_rates[nr->nr_nrates - 1] & IEEE80211_RATE_VAL) / 2 is the current nominal rate in Mb/s, is that correct? Curiously, what I observe with the RTL8192EU is that after associating, that value starts at 1 and as transmissions are made, moves to 54 in increasing steps, and then stays there. I guess that corroborates your point about incorrect information being returned by the device. Unfortunately I don't have another wifi adapter to test with. Anyway, thanks for your help, I'll give it a rest now. -- Cheers, Björn
