My internet has been cutting out annoyingly regularly for the last few weeks, sometimes it lasts only a few minutes, sometimes it is intermittent for half an hour or more. Sometimes rebooting everything helps, sometimes it doesn't. It just all seems to be totally random.
I use a 3rd party Asus router so the hub is in modem mode, I initially assumed the issue was the Asus router as it was 5 years old so treated myself to a new one, but even with the new router the issue still remains.
I have been browsing the forum and have seen issues like this where people have asked for the details of the network status of the hub so here are mine (I restarted the Virgin hub a couple of hours ago):
From what I've read, the downstream power seems a bit high, but I already have a 10db forward path attenuator on there that was added by the engineer who initially installed my Virgin Media stuff about a year ago.
And, another strange thing (to my untrained eye) is that the last network log entry was almost 6 hours ago, but I was experiencing issues about 10 minutes ago, but I have no idea if that means anything or not.
Your D/S power is lower than mine and mine is absolutely fine -6 --> +10dBmV is normal!
Looking at the stats; all looks fine but the logs tell a different story!
Hang tight for a VM Forum Rep to take a look!
Also, set up a 'Broadband Quality Monitor'. This will monitor the state of your connection and record any network dropouts etc - You can do this at ThinkBroadband (https://www.thinkbroadband.com/broadband/monitoring/quality) Give it a while to gather data and then click 'Share Live graph' and paste the 'Direct Link' into the forum!
