Sometimes can't use network service in only 5GHz of Archer C7 v5
When I play YouTube on LGE TV thru WiFi, sometimes AV is stopped.
At that time, if check TPLink admin page, can't see TV in 'Wireless Clients' list.
- Occurred no matter which encryption mode is used.
- Occurred no matter which CH is used.
- Occurred no matter which phy mode is used.
- Didn't occur in 2.4GHz.
- Didn't occur with Archer C7 v2, and any other AP.
To narrow down more, I checked the captured air packet during ping test. (TV -> TPLink AP)
- Since network service became unavailable, there was no ping reply from AP. And TV mac was disappeared in 'Wireless Clients' list.
- But there was no deauth or disassoc from AP, so TV still sent ping request.
- TPLink AP still sent BlockAck for ping request, but seems didn't handle the received packet in AP side, because no ping reply.
I tried to attached the air packet, but failed.
If you want to get it, just let me know how can I attach.
