Re-installed 3.28 and reset config using netinstall, and upgraded FW to latest version (2.20)

I can log in to the router from the console and move around, but ss can be seen, as soon as I try to paste a config to the console, the board performs a memory dump and reboots once again.

Is the RB ready for the thrashcan, or is there still hope?

It seems something wrong with mPCI. Replace wireless card and try again.
