network topology: 80211g uplink - 30Mbps is brought into litebeam-5AC that is running AP (WDS) mode on 5GHz radio. client device is a laptop (dualcore 2.4GHz) running QCA9880 card on ubuntu 10.04 with kernel 4.9. description: booting ubuntu defaults to performance governor (personal modification), opening speedtest.net upon boot and measuring throughput gets me about 25Mbps download speed. setting lowest CPU scaling freq of both cores (600MHz) and repeating the speedtest gets about 29-30Mbps in download. i have verified these speed differences while downloading several iso files. confirmation: identical results have been observed on a live booted ubuntu 19.10 identical results have been observed on ubuntu 10.04, but using ethernet connection from archer c7 that was connected in client mode to litebeam5 ruled out so far: -using regular AP-STA instead of APWDS-STAWDS interfaces does not change a thing -switching to Ben's CT driver and firmware had no impact, the bug is present with it too -using different card QCA9862/QCA9880 behavior is the same
