I've not had any trouble with the tp-link plug, I had it running some different miners for a few months with no issues. It's handy to be able to keep track of the power.

I can't seem to connect via ssh, I just get

connect to host 192.168.1.118 port 22: Connection refused

any advise? Can you set these back to default settings? All the firmware links seem to only be applicable to writing USB pens, and not to a micro sd card.
