Hi, my system was setup by a friend of a friend, and they sent me a link to log in and see my system via the VRM Portal, after a few breaches of trust from my friends friend, i do not want them to be able to log in and scroll through my system, can i rename my system so only i can log in? i have removed the router cable, but i also then cannot log in, so yeah, do i have to reconnect to the internet in order to change the setting? or can it be done direct Ethernet to laptop ?
