I posted a topic that my existing setup (wifi is not discoverable on any device mobile/tv etc. since last few days).
I upgraded to latest version few weeks ago, tried to play with some settings and now wifi has stopped:
Model TP-Link Archer C2600
Architecture ARMv7 Processor rev 0 (v7l)
Target Platform ipq806x/generic
Firmware Version OpenWrt 21.02.3 r16554-1d4dea6d4f / LuCI openwrt-21.02 branch git-22.083.69138-0a0ce2a
Kernel Version 5.4.188
Local Time 2022-09-10 20:10:13
Uptime 6h 12m 32s
Load Average 0.37, 0.35, 0.33
I need to change my wifi from 5 GHz to 2.4 GHz or setup both to work.
I am little confused as well, on how to go back to original firmware.
Have downloaded original firmware (renamed same), got tftp client/server installed on Windows 10 PC as well, not sure what to do next.
