The pattern is that when the connection stop working I see something like this in the log: [ 8735.159091] wlan0: moving STA 1c:c6:3c:1f:50:68 to state 4 [ 8735.197298] wlan0: Rx A-MPDU request on tid 0 result 0 [ 8735.566368] wlan0: Open BA session requested for 1c:c6:3c:1f:50:68 tid 0 [ 8735.573701] wlan0: activated addBA response timer on tid 0 [ 8735.578826] wlan0: switched off addBA timer for tid 0 [ 8735.578834] wlan0: Aggregation is on for tid 0 [ 8749.687530] wlan0: tx session timer expired on tid 0 [ 8749.687558] wlan0: Tx BA session stop requested for 1c:c6:3c:1f:50:68 tid 0 [ 8749.700550] wlan0: Stopping Tx BA session for 1c:c6:3c:1f:50:68 tid 0 This is what I do: First establishing a connection, then after a while any traffic seems stops for a period and sometimes it recovers from that point. If not a disconnect/connect (using ConnMan) dance fixes the problem. Here some more logs with the reconnect dance.
