Given the history it is hard to say what is the best way to move forward.
Bitdefender has caused some issues in the past but they weren't disconnect issues , thread here
Grab hwinfo to monitor temps in any case
Given you are wired ethernet at the moment are you able to use a wireless connection as well ? this would effectively change the adapter being used.
Easiest way to test a different network cable is use your flatmates for 5 - 10 minutes ?
I do use HWMonitor. Temps are normal.
Theoretically I can use a wireless connection, but I don't have the adapter for it.
I will try to use my flatmate's cable. This will take some time tho. I'll give a comment on it when it is done.
