One of our customers reported that our ath10k stations were only able to connect at 54Mbps speeds. This is using somewhat hacked 3.17.8 kernel, but it looks like 3.19 has the same code checks for AIFSN. It looks like their beacon has bogus AIFSN info, and sniff of the beacon does show AIFSN set to 0. Kernel dmesg logs: wlan0: authenticated at: 1424969385.456415 wlan0: AP has invalid WMM params (AIFSN=0 for ACI 0), disabling WMM wlan0: associate with 00:18:25:06:4a:b4 (try 1/3), at: 1424969385.457148 wlan0: RX AssocResp from 00:18:25:06:4a:b4 (capab=0x401 status=0 aid=2) at: 1424969385.476681 wlan0: associated at: 1424969385.477265 But a commercial phone connects just fine to this AP, and reports ~780Mbps link speed, so it at least thinks it is doing VHT. My question is, should we just warn and ignore this bad AIFSN, or is this really a fatal issue as far as enabling WMM?
