Hi, I also have same observations. Rx rate is not getting updated in iw station dump command with firmware version 10.2.4.70.66.Data Throughput is also degraded by 30Mbps with this version.My measure throughput was 180Mbps with firmware-5.bin_25_2.1 for HT40 mode(2x2).
Sometimes I can see 1 SS in station dump while my radio is 2x2.Is there any speed difference for the FW version 10.2.4.70.66?
