However, the maximum throughput i can get is around 70Mbit/s which is far away from the throughput achieved by many users (UDP traffic). In a setup with those cards we can observe a UDP throughput of approx. 640Mbps. > > I have notice that Bit Rate keeps fixed 6 Mb/s . and it dose not responding to any commands to change it. While running iperf client on the station I can also retrieve the Tx bitrate of 6Mbps with both iwconfig and 'iw wlanX station dump'. Version of iw has some impact on the output too, I have version 3.15. I don't know a tool which shows the right info on the transmitting node... But a third node which is configured as a sniffer shows Tx bitrate of 1299.99Mbps :-) > > The machines used: > Ubuntu 12.04, Kerenl 3.16 , updated regulatory to cover 80Mhz channels , and the latest firmware Our nodes are also running 12.04 but still with the default kernel 3.11.0-15-generic. dmesg | grep qca98 shows [ 4.594975] ath10k: qca988x hw2.0 (0x4100016c) fw 10.1.467.2-1 api 2 htt 2.1 Further, as Kalle suggested, we installed the ath10k driver from backports-3.15.1-1.
