Hello,
I am using following system:
Model: TP-Link Archer C7 v5
Architecture: Qualcomm Atheros QCA956X ver 1 rev 0
Firmware Version: OpenWrt 19.07.2 r10947-65030d81f3 / LuCI openwrt-19.07 branch git-20.064.69776-e8c638c
Kernel Version: 4.14.171
There is an industrial wifi that my router connected to which gets me a fiber connection on other end. My service supplier is telling me that there is no wifi drops on their logs at all. On the other hand, my log has following:

I am not sure when that drops occur. I feel them mostly when I am doing Remote Desktop Connection, TeamViewer Connection and similar. However it is not limited just with such. I suspect it goes down on Skype video meetings, and watching Youtube videos too.
I have identified following drops in my log so far:

Line 765: Wed Apr 22 11:08:59 2020 daemon.notice netifd: Network device 'pppoe-wan' link is down
There seems to be no fixed amount of time between drops.
I have already read several threads about this specific problem. None of them seems to have a solution. Owners of these threads stopped responding at some point. It is not clear if something has helped them or they gave up and reverted back to stock firmware of their devices. I do hope that I can fix it on my device.
My WAN interface settings are as following:
LCP echo failure threshold: 0 (default)
LCP echo interval: 5 (default)
I appreciate any help.
Thanks & regards,
Ertan
