Still max dl speed 16 mbps. ok, so it could be something else... maybe it's a driver bug, maybe something is outdated [avoid hostapd older than 0.7,3], or maybe just a simple configuration problem [on either side]? you can't tell that by just looking at the low throughput figure. Instead you probably have to capture the handshake between the AP+client and look who's lying about their 11n capabilities. Luckily, all mac80211-based driver come with a nifty feature which allows you to monitor any incoming/outgoing data. Just setup a monitor interface. and start a sniffer. tcpdump/whireshark is more than enough. > btw, Can I use ath9k_htc with my Atheros 9170 in N master mode. no, ar9170 is too old. ath9k_htc is exclusive driver for the ar9271,ar701x+ar928x devices, which appeared in late 2009. > What about performance? it's ok.
