Archer AX55 Pro (v1) has become unreliable
I purchased the AX55 Pro almost exactly a year ago and I've been very happy with it. (It was an upgrade from another Archer model and exclusively use TP-Link network devices in One Mesh mode.)
Recently, however, I've been experiencing outages on a weekly basis. The pattern is very much that I go to sleep with everything working fine but then wake up several hours later to find that the network is still visible but with no internet service. (There is nothing to indicate any issues with my cable router.) The only fix is to restart the AX55 Pro. Everything then works OK again only for it to happen again within a matter of days/ a week.
This could be a hardware fault of course but I can't help feeling that these issues started after applying the v1.3.1 update in July.
To clarify my network:
Ground floor: Virgin Media Hub 5 cable router in modem mode > Archer AX55 Pro v1 > TL-WPA8631P Kit v4
First floor: RE705X Range Extender v1
Basement: TL-WPA8631P v4
Out-building: TL-WPA8631P v4
I've set my router to automatically reboot itself once a month. I manually reboot the other devices with the same frequency.
Please can you advise what can be done to fix this problem.
Thank you.
