I've sent your these data, do you need more from exactly the same setup? :) I could make tests in the middle of working say, when environment isn't so noisy -- less APs are seen, and spee is better. > I have a nasty feeling that the AR9280 series NICs report some rather > high NF values.

BTW, is here other ATH PCI chipsets with 802.11n? I've checked all Mirkotik Mini-PCI cards, for example, all of them are based on 9820, with different setups of RF part, some of them are single-band (2.4Ghz only), some of them are dual-band, some of them are dual-band and have amplifier, which adds some dBs of output, but chipset is the same. And the same with TP-Link cards, which could be purchased here (in Russia). It seems, --=20 // Black Lion AKA Lev Serebryakov
