I installed Openwrt in my Archer C20 but the 2.4GHz wireless was having some problems randomly shutting down, usually when using a lot of bandwidth (netflix, youtube, etc).
So I tried to install again the OEM firmware to fix those problems. I used:
scp tplink_archer_v5.bin email@example.com:/tmp/firmware.bin
to upload the oem firmware and used
sysupgrade -F /tmp/firmware.bin to force to install (I know it is not recommended), but now my router has all LEDs off, and it only turns on the corresponding leds if I connect a device in LAN/WAN ports.
I tried to unbrick using TFTP sending both the OEM version and the openwrt version. The TFTP is listening but after upload it was in the same state.
What do you recommend me try to revive my router? Thank you
