Are different MCS rates supported when you are running in noack mode?
Context: I am using ath9k modems+Compex WPQ864 (linux-ipq864) boards. I have configured one of the boards as Access point and other one as station. I have connected them on wlan and ping works. I am trying to turn off ack using:
iw dev wlan1 set noack_map 0xff
And I tried to modify MCS rates using:
iw dev wlan1 set bitrates ht-mcs-5 7
But this works as intended when ack is on, but has no effect when I turn off ack using the above noack_map command. And the rate is always at 6Mbps.
iw wlan1 station dump
shows the following output:
inactive time: 570 ms rx bytes: 190293 rx packets: 1700 tx bytes: 187747 tx packets: 1621 tx retries: 0 tx failed: 883 rx drop misc: 1 signal: -37 [-44, -38] dBm signal avg: -36 [-43, -37] dBm tx bitrate: 6.0 MBit/s rx bitrate: 13.0 MBit/s MCS 1rx drop misc: 1 signal: -37 [-44, -38] dBm signal avg: -36 [-43, -37] dBm tx bitrate: 6.0 MBit/s rx bitrate: 13.0 MBit/s MCS 1
Any help is appreciated.
