Constant short disconnections

I have a Super Hub 2ac and for the past 3-4 days, have been getting frequent disconnections from the Internet. Often it comes back on within a few seconds, but the interruption is enough to spoil online gaming or video meetings! Occasionally I have to power-cycle the Hub to get the service back.

From what I've seen on this forum, many other people are having similar issues so I wonder if there is a national fault with Virgin? I'm seeing a lot of "Lost MDD Timeout" in the network log, along with the occasional "RCS Partial Service" and "No Ranging Response received - T3 time-out". 

I have posted my Downstream and Upstream reports as others have been doing, just in case there is a fault at my end.

Re: Constant short disconnections

Those stats are all pretty good. post up the logs as well.

Are the issues only evident on wifi connections or do you see them at the same times on devices connected on ethernet cables? If you don't know, can you check to help diagnose whether it is just a wifi issue or it could be network connection related?

In the meantime, if you haven’t already, set up a free and secure “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts. It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph” (as per instructions on the TB website) when it starts to develop.
