Install OpenWrt on TP-LINK Archer c6 v3.0 BR

[dsouza]

OK, the good news is that now I have successfully built 21.02.2 for the Archer C6 v3 (backported some C6 v3 files and successfully built it).

However the bad news is that the stable build 21.02.2 for the Archer A6/C6 v3.x is broken. When enabling the 5Ghz radio the router enter in a boot loop (I tested in in my C6 v3.2 and confirmed this issue).

For this reason I will not make this build (21.02.2 stable for the C6 v3.x) available for downloading.

This issue was already reported in the 21.02.2 thread below:

OpenWrt 21.02.2 Second service release

MT7621 builds don't seem to be updated before the official release, as the build date is still showing as February 18. For some devices, 5 GHz WiFi is broken. Enabling it from LuCI makes the router reboot, and then it reverts to disabled state. Router is bricked on force enabling it, and also on flashing 21.02.2 with earlier configuration preserved (with 5 GHz WiFi enabled). Affected devices are TP-Link Archer A6 v3, Linksys E5600, and possibly others. I and others reported this issue earlier…
