Hi
I connect via wired ethernet to my Hub 3 and my broadband connection is intermittant. I can be browsing then the connection drops and comes back around 30 seconds later. It's very annoying! I have a couple of PC's (all wired) which exhibit the same behaviour. Of course I have reset the Hub and swapped out cables etc but nothing helps. I'm trying to work from home but it's almost impossible.
If I log into my account and run the broadband test, it mostly shows there are no problems because the internet comes online just before I perform the test. There are quite a few errors shown in the network log of the hub:

Can anyone help?

Hi John
Here is my BQM for yesterday. I'm not sure whether the yellow spikes indicate an issue as such [?] We did have some dropouts yesterday but unlike the previous day, we could at least use the connection. The dropouts lseem to last for about 10 seconds. It feels like the VM network is overloaded, trips and then resets itself a couple of seconds later. What do you think?
22-07-2020 14:28 - edited 22-07-2020 14:31
The BQM shows no evidence (I can see) of network disconnections - these are usually evidenced by full height vertical red bars that last for the duration of the "downtime". Ping intervals are 1 second - so anyhing of that length and above, not received back, will show. See here for explanationss
https://www.thinkbroadband.com/faq/broadband-quality-monitor
Does this time-span cover your known down times and what does the network log show at those times as well?
If its not evident in either, they are probably just wifi connection drops.

i have the same issue did any body fix this, we have hub3 , 2 pcs on wired conenctions with win 10 64bit and both drop out like this, only for tiny ammounts of time but connection dies and everything crashes, drive me crazy and my son crazy while gaming. logs hardly show anything, speed is 200mbs hardly using the max, driving me mental, video crash , games crash , pc tell me lost conenction and by the time you notice it its allback on again. tried to call vm buy lines are to busy to conenct the call wow! been doing it a few months so its not snow related. thoguht it was my cables router or pc , i broguht new pc and changed cables and ports. reset the router , reconfig router . the works still does it.

I’m having this exact same issue on LAN connection even after a technician came out last Thursday!
We were having issues with this on our Hub 2 (LAN as well as Wi-Fi), so he set up the Hub 3 that I’ve had since January last year and never bothered to set up due to all the distractions with Covid.
This is an extremely poor and unstable service right now, and it’s affecting my new home working environment and the online team meetings this entails. Also live streams and gaming with others.
At first, I thought my reluctant installation of Windows 10 early last year might be the cause, but I remember having these ‘page hanging’ and freezing issues before installing Windows 10. It also happens on all devices like my smartphone, my Playstation, and my dad complains of the same thing when he streams through his TV.
Since others are having this issue, and since the technician visit hasn’t resolved the issue, I’m thinking of leaving Virgin Media, and I’ve been with the service since it was called Blueyonder! I hate to leave, but this is affecting my productivity too much now.
Oh, and I see my LAN just went down again on the Instagram live stream I’m watching on my laptop while I type this on my phone. Lasted about 30 seconds. 😕
Not happy. Very close to turning my back on Virgin Media to seek a more stable service.
Anyone else also notice that you suddenly get stronger download results closer to your payment plan on speedtest as soon as you phone them to report speed issues with your service? Very strange, that.
