Hello, I have been suffering with this problem with my internet for a few months now. I am experiencing Disconnects from the router plus lag spikes. I have been in contact with Virgin multiple times and they have sent out about 5 engineers to look at the issue and they still have not fount it. The engineers have replaced my router 4 times, the coaxial cable to the router. Have spent time investigating the cabinet and still having no joy with it.
I play competitive Call of Duty and having these issues will not let me get online at all sometimes, usually I cant load the game up as it disconnects me from the battle net servers. I have a LAN event in a few weeks and not been able to practice at all. Not just Cod I have the issues its pretty much everything. Find it hard to watch anything connected to the WIFI so I usually use my 5g.
This is the day after having a engineer out for 2 hours looking at my issue and replacing everything stated above.

I can provide every day's graph on my old router from the 5th of April if needed.



Sorry for the massive post, let me know if I can provide any more information, Just had enough of this now.
