Intermittent connection
I’ve been having this issue for months where my connection is perfect for maybe a few days to sometimes over a week, then it will just completely disconnect for hours, for days if not weeks. I’ve had an engineer come round, they replaced my hub with a hub 5 (originally a hub 3) which seemed great at the time but the issue just never fully went away. Done all i can to attempt to fix it, but realistically there’s not a lot i can do. this is todays connection: https://www.thinkbroadband.com/broadband/monitoring/quality/share/42b53d2b86f43b5e4cb51298e5366c734a636424 The above images are some of the worst days ive had but there have been only maybe 5/6 days like this so far (a majority of the time its just 20 minutes then its back for maybe 15)
Too Many Disconnections!
Back again, in desperation! I've been having problems for months, but in the last few weeks it has become progressively worse. After an engineer visit new Hub 5 and (apparently!) a new connection at the cabinet, it has actually gotten worse. I have requested an outdoor survey, as all the equipment in my house has recently been replaced and have another engineer visit provisionally booked for 22 December. However, I am now at the point where I will be requesting an early exit from my contract, as this really is unacceptable. My previous request for help were not progressed as I was running my hub in modem mode, so I have now switched it back to router mode in the hope that some kind of diagnosis might be possible.

Since 13 November I have had either no internet or intermittent internet. First outage on 13 November following a storm resulted in 3 new hubs, 3 ONU boxes, 5 engineers to confirm a network issue. Internet working on 19 November. Next outage on 13 December so dad I have had 2 engineers. First one confirmed network issue to be resolved in 24-48 hours. No internet or intermittent internet called Virgin 3 times 2 advisors confirmed Virgin were aware of network issues yet, 3rd advisor confirmed no issues or outages and another engineer sent. He arrived Monday of this week and could not see any issues with the equipment in the house and spoke to his manager and network team who knew of no network issues. We are now on day 11 of no or intermittent intermittent internet. The app is mostly useless in saying everything is working correctly but last night it did give a message after doing a hub test that there was an intermittent issue. Can anyone advise how to get this issue escalated to someone who will fix it? Currently solid white light on hub 5 and no internet.
Connection dropping intermittingly
Good afternoon! For about a week now I've noticed that my internet connection drops for around 5-10s every 20-60 minutes, sometimes multiple times over a 5 minute period and I have no idea why. I am currently wired to the hub as is my other laptop but I notice the connection dropping on my wireless devices around the same kind of time too, others in the household have also noticed this. I have also seen on Reddit and here that others are in the same boat across the UK so I know it's not isolated to me. Is there anything that can be done to resolve this? I will provide any information asked and run whatever diagnostics I am advised to. Thank you.Hub 6 no internet connection
We have just moved into a new apartment and had a technician out to install the Wi-Fi router on Tuesday this week. There was already an existing connection point which he tested and confirmed was good. He set-up the router and assured me that everything was working. I checked to see that the Wi-Fi network was visible (which it was) before he left. Unfortunately when I connected to the Wi-Fi I discovered there was no internet connection. I followed the troubleshooting steps on the virgin media website. I rebooted the box, tried connecting on other devices and forgot and reconnected to the network. Nothing worked. I rang Virgin Media support and they advised that the connection had not been fully activated and that I should wait 3 hours after the technician visit. So I did but it still did not work after 3 hours nor the next morning. It’s now Friday, I’ve been away for a couple of days, and there is still no internet connection. Very frustrating given that I specifically requested a technician call-out to avoid any connection issues. When I run the network diagnostic tool on my hub 6, I get the following; Can anyone advise on how to resolve please ?
Connection randomly drops
From Wednesday on this week my connection has been dropping or becoming very slow at random, I obviously checked the service and it stated there was a problem with inconsistent connection in my area, so I thought that explained it. However I am still having issue now and further checks say there are no problems in my area, I can go hours without a drop and sometimes it will then go off and on a few times in an hour and then be fine again, I went through the remote process today of restarting the hub in case this does anything a local reset doesn't but it made no difference. When I check Windows it states that my connection is low quality, if I restart my PC it says the same so I restart the adapter which then fixes it, it should be noted despite this my connection is back up at 1155 Mbps Download and 105 Mbps Upload which is my average connection speeds. Windows also reports no issues with my network adaptor but just to be sure I installed the most recent driver. I'm wondering if anyone else has had similar issues as I see form outage sites that Virgin appears to have had a number of issues recently?Junction cabinet in my hedge
Virgin Media applied to the local highways agency to replace a 85cm high cabinet on the highway outside my house in 2023. They actually put a replacement 1.2m high by 1.2m wide cabinet in my hedge, next to my drive. Earlier this year they dug up my hedge looking for cables under the cabinet and the hedge is now wrecked. I can’t replace it with a fence because the cabinet is in the way. I’ve tried complaining but four months later I’m just being fobbed off with excuses or promised callbacks which don’t materialise. I want to escalate the complaint but am not sure where to go. Is it Ofcom or the Communications Ombudsman?Internet only works between certain hours?
My internet connection has only been working properly between roughly 10:09am and 4:01pm every day, and this is now day 5 of the issue. Outside of those hours the service is basically unusable due to the upload speed dropping. I have run multiple speed tests and the pattern is exactly the same every day. Before 10:09am and after 4:01pm, my upload speed sits at around 0.20 Mbps, but between those hours it jumps to around 40 Mbps. I have made countless calls to Virgin Media and am getting nowhere. An engineer is due to visit today between 12pm and 4pm, but I am not hopeful as this clearly is not an isolated fault. I live in a block of flats and multiple neighbours in my block, as well as the block next door, are all affected by the same problem. One neighbour already had an engineer visit yesterday and was given a replacement router, which only worked for about 10 minutes before the issue returned. I am using a Hub 5 and have only been with Virgin Media for two months, so this is incredibly frustrating. Has anyone experienced anything like this before or got any ideas what could be causing such a specific, time-based upload issue? Any advice would be appreciated. Thanks!New Hub 5 keeps dropping internet connection
I had a new Hub 5 a few weeks ago (replaced a Hub 3 and briefly a Hub 4) and have now had a few times where the internet just stops for a few minutes, then comes back. During the outages I am able to talk to the Hub 5 quite happily via Wi-Fi and see its status page , so this seems to be some kind of internet/cable modem issue rather than a Wi-Fi problem. All our devices lose internet at the same time, even those cabled into the hub via Ethernet. Note that we had zero problems like this with the Hub 3 for all the time it was here (a week or so prior to the Hub 5 arriving). I had a look in the Hub 5 status pages and during the outages had the following things logged: 24-11-2025 14:22:03 critical Unicast Maintenance Ranging attempted - No response - Retries exhausted;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 24-11-2025 14:22:03 critical 16 consecutive T3 timeouts while trying to range on upstream channel 8;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 24-11-2025 14:19:04 critical Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 21-11-2025 20:22:41 critical No Ranging Response received - T3 time-out;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 21-11-2025 20:22:40 critical Unicast Maintenance Ranging attempted - No response - Retries exhausted;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 21-11-2025 20:22:40 critical 16 consecutive T3 timeouts while trying to range on upstream channel 8;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 21-11-2025 20:22:34 critical Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 16-11-2025 11:09:30 critical Unicast Maintenance Ranging attempted - No response - Retries exhausted;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 16-11-2025 11:09:30 critical 16 consecutive T3 timeouts while trying to range on upstream channel 8;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 16-11-2025 11:09:24 critical Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 14-11-2025 17:20:25 critical Unicast Maintenance Ranging attempted - No response - Retries exhausted;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 14-11-2025 17:20:25 critical 16 consecutive T3 timeouts while trying to range on upstream channel 8;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; 14-11-2025 17:20:19 critical Started Unicast Maintenance Ranging - No Response received - T3 time-out;CM-MAC=70:7d:a1:74:e7:45;CMTS-MAC=00:01:5c:7b:ac:54;CM-QOS=1.1;CM-VER=3.1; None of that means anything to me, but I have found other people with similar issues and this being a total pain to get sorted. I've just called the VM support number and they're going to book a techy to visit on the afternoon of 26th, but being an intermitted fault I suspect it's unlikely it'll do it whilst they're here. The person on the phone saw no issues when they looked at the connection (I'm guessing they don't get to see the Hub logs...) In the 3.0 Downstream Channels bit, one line stands out as significantly different to all the rest: Channel Locked Status RxMER (dB) Pre RS Errors Post RS Errors 8 Locked 39 196 761 All the other channels are at low single digits for Pre RS Errors and zero for Post RS Errors. No idea if that's related? The log messages are talking about upstream channel 8 and the above is downstream channel 8. Also, when we had the Hub 3 fitted years ago, a 6dB attenuator was fitted. I have no idea if that's still needed, I recall the installer saying the signal was a bit strong. Perhaps the Hub 5 would work better with this removed, or maybe it even needs a higher value attenuator? Can anyone tell me what range of numbers I should be looking for in the Downstream or Upstream sections? I'm guessing there's a normal operating range for the dBmV power levels? Thanks for any help, advice and suggestions 😊
