I can tell you my issues has been ongoing for over a year. With dates always changing for when the fix will be done. I was assured the fix date for my area was May 17th 2017. That was the last time they told me a fix date. Since then I have wasted time on the phone; trying to find out when if ever my internet will actually be what I am paying for.
There is a rumor that the company wont invest anything till brexit has been finalized. I guess the Owners are doing what wind farm people do; set them up with huge Gov grants reap the rewards & invest nothing then sell it on. Maybe Virgin will soon be in the hands of Mr Green as he is great at killing companies. But virgin do not need help in this. The more people they sign up the more people get frustrated and the more who leave bad reviews for VM as a company.
As I am not contracted to Virgin I will see what Sky can offer, then when it is installed I will inform Virgin Media to cancel my account.. Also Virgin Media do not broadcast RT News... strange as it is on Freeview...
I think it would be wise to determine what the fault is first. there are many problems that can affect internet speeds including over-subscription. just because someone is suffering from slow speeds due to utilsation, doesn't mean that it is the sole cause of slow speeds.
I would test the internet speed with a device connected directly to the hub by ethernet cable, testing during the day and again during evening peak.
If you are getting headline wired speed during the day and poor speeds only during evening peak, then it looks like a contention problem, If you are getting poor wired speeds all the time, then it looks like a technical problem which can be fixed relatively quickly.
Wireless is affected by maby external factors making it unsuitable for testing the actual connection speed accurately.
If VM confirm it is a utilsation problem, then I would leave as it is very unlikely to a quick fix.
I rebooted the the router etc about 1 pm then turned it on again after 30 seconds or so, as it was down to 0.07Mb/s, I am paying for an upto speed of 200 Mb/s, it has been hit and miss for 2 weeks now, sometimes it is so slow it can't even do a speed check....
