Factory reset Alta Control

My control become absolutely unresponsive. It getting DHCP allocated address however ping, traceroute, ssh or lynx did not have any success. So only option which I have - to perform “factory reset”. All articles here or elsewhere regarding performing factory reset did not help at all.
So IF anyone can help me to find possible solution for my issue, I’ll greatly appreciate it.

That’s fascinating that it can DHCP but cannot ping. Are you able to get a packet capture from a router that is able to ping it and see the DHCP exchange?
