Hi,
I messed up when I was downgrading the firmware and I checked "clear all custom configuration" and as a result, the /etc/config/wireless file is missing and the LED on the Antenna no longer work. So wifi doesn't work. I am not sure what other configuration files are missing. A factory reset doesn't not help to restore the wireless file.
Can someone share your firmware with /etc/config/wireless and other files in tact so I can restore my router back to the "default" state. TIA
