Hello,I've been having packet loss issues for a while now and I have tried contacting Virgin Media via Whatsapp for support, but all that was able to be done was factory resetting the router, which did nothing.I have used multiple programs to try and observe the packet loss and try to figure out whats causing it, and most of the time it seems to be related to ip addresses that end with "network.virginmedia.net". This was with programs such as PingPlotter and WinMTR.I am using a wired connection to the router, and I've tested packet loss on other devices running on WiFi, they are very similar which is unusual considering wired should be better.When running the service status checker that Virgin Media has it always prompts me saying that there is a problem, except there doesn't seem to really be a fix for it, since it always resorts to either a factory reset or a reboot, either of which do nothing.Would appreciate any help or advice.Thank you.

You need an engineer or this is a street cabinet fault that is yet to be reported.Almost all the Downstream channels are below acceptable levels of power.Only one 3.0 DOCSIS channel is connected - we normally see between four and six upstream channels.

Thought I should also provide this, despite only starting it recently since I just found out about it, it also shows pretty clearly that there is an issue.

If there a fault in your street ? Call 0800 561 0061 to find out.

Seeing only 36.4 Mb/s Downstream to the VM Hub should be the start of your focus.

The bottom of the Realspeed test is cropped off,
so we can not tell if 19.7Mb/s Hub Upstream is OK or is this low too ?

Check the Downstream / Upstream status tabs of the VM Hub for signal level or error issues.

  Just called the number provided as well and apparently there are no faults in my area.

  Thank you Client62, I'm not sure how I would go about getting an engineer to perform a check. If there is a number I could call or any other method would be appreciated.
