[ath9k-devel] 802.11n throughput with ath9k

[Tomasz Czaus <tomasz_czaus@go2.pl>]

Hello,

do you get such a performance in AP mode too? I have 300Mbps TP-Link 
TL-WN951N MIMO card an in AP mode I never get more than ~25Mb/s. Average 
result is ~7-15Mb/s. Honestly, I am a bit disappointed because of my 
previous card (TP-LINK with Atheros AR2413 802.11bg NIC (rev 01)) 
provided the same performance or even better because 22-25 Mb/s was 
stable result.

Do you have any suggestion how to use my new card in AP mode with full 
performance of 802.11n mode? Here is my hostapd.config file:
