When the station break off, ping can not reach ap. wifi still connect. kernel have no error info. iwinfo signal still change.

ap with the other station still alive.

Use wpa_cli scan command, will awake station, and ping alive.
wifi command also work.

/proc/interrupts ath9k still alive.

I can confirm this report. i have multiple TP-Link WR1043ND v3.0 which exhibit the same behavior.
Usually, both the WDS station and the WDS AP report in CLI/LUCI a connection, but no data is transmitted over the wireless link. sometimes the RX speed is locked to 1 MBit/s or the AP disappears completely until reboot. reboot fixes the problem until it's happening again at random intervals. log files are clean.
