This problem occurs only after the AP and station are badly(?) connected, and once the connection is established normally, this problem does not occur on the good connection. And once this problem occurred, it won't be fixed by itself until the AP and the station are reconnected. I have investigated and I have found two differences between the good connection and the bad connection. The one is the error messages on dmesg, <...> [ 2826.432784] wlan0: Limiting TX power to 21 (24 - 3) dBm as advertised by 04:f0:21:20:38:09 [ 2827.296925] wlan0: Rx A-MPDU request on 04:f0:21:20:38:09 tid 0 result 0 [ 2827.297483] wlan0: Rx BA session stop requested for 04:f0:21:20:38:09 tid 0 recipient reason: 0 <--- from this line [ 2827.297578] wlan0: Rx A-MPDU request on 04:f0:21:20:38:09 tid 0 result 0 [ 2827.298694] wlan0: Rx BA session stop requested for 04:f0:21:20:38:09 tid 0 recipient reason: 0 [ 2829.074439] wlan0: Rx A-MPDU request on 04:f0:21:20:38:09 tid 6 result 0 <-- to this line <...> The another difference is in "agg_status" file on Station side (/sys/kernel/debug/ieee80211/phy0/netdev:wlan0/stations/XX:XX:XX:XX:XX:XX/agg_status).
