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something is outdated [avoid hostapd older than 0.7,3], or maybe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.

no, ar9170 is too old. ath9k_htc is exclusive driver for the
ar9271,ar701x+ar928x devices, which appeared in late 2009.

it's ok.
