I am currently at Parents’ house and have connected to their virgin media hub 3.
When I lived out and used the virgin media hub 4, I experienced this issue.
I have recently upgraded my parents’ internet to the Virgin Media hub 5 and am now experiencing the issue again.
The issue:
I currently play on a laptop that is always connected to the charger. When I used hub 4 and hub 5 without an ethernet cable, I would instantly disconnect from WoW after logging in. In most cases, it would cause my laptop to disconnect from the internet for a few seconds altogether.
If I remove my laptop charger, I can connect fine to wow.
If I keep my laptop charger and use an ethernet cable, I can connect fine to wow.
NOTE: I CAN CONNECT FINE WITh MOBILE WIFI + Charger
I am unsure what the issue is. I had previously suspected a disruption with my wi-fi card when the charger was plugged in but I never had this issue with the hub 3. I then suspected the issue was with the router, and that the newer virgin media routers were blocking packets from Blizzard, but I cannot find the cause.
My guess with the most likely cause is the laptop charger. Could also be electric grid related, but unlikely unless the locations were in the same area/same building etc.
Try with a different charger and see if that gives different results. Difference why mk 3 works while others not is that it might use different frequency for wifi (without knowing specs I would guess 2.4 GHz in the older and 5 GHz in the newer devices).

The laptop is only 3 years old, so should be compatible with 5Ghz. It is the same building and even the same wi-fi spot, and my wi-fi works fine using my mobile data. I’m assuming it’s an issue with the new router blocking packets but can’t find anything regarding it.
My bet is still some interference so my suggestion is still to try with a different charger and possibly different wifi AP as you haven’t mentioned trying those suggestions I made in the earlier thread (no wonder the problem felt bit familiar). Phone is probably closer to your laptop than the router as well so you could move the laptop next to the router while charging and see if the connection improves closer you get.
Problem doesn’t really sound like router dropping packets as that should happen when using either type of connection or not at all. Trying different AP would probably rule that out even if you keep the router which I assume is ISP provided since wired connection works.
