Intermittent service after multiple engineer visits
I'm writing here as I feel I have exhausted any possible avenues through customer services over the past 6 months or so, and I'm currently stuck in an endless loop. After my most recent call today I have a logged yet another complaint, but it seems that the only resolution suggested is to send a third engineer from the same team. For context, I'm running my Hub 5 in modem mode with a third party router, but I've confirmed the issue is still present when using the Hub 5 as a router. To summarise the current situation: At random intervals (this can happen multiple times in a day, or not at all for days) my connection will drop. This typically shows as T3 timeouts (often on all consecutive channels) in the network logs. There is no pattern that I have been able to ascertain. The connection will resume after a minute or so without any action needed, but obviously the the loss of connection will impact on anything I am currently doing (work calls, typically). The quality of my service other than this is fine, and I have no issues with speed or network quality outside of this particular issue. I can't put my finger on when the issue first started occurring, but there have been no changes to equipment or in the house since the connection was originally installed. After doing the usual troubleshooting and confirming there were no apparent issues on my end, the first engineer was sent out. The first engineer rebalanced the signals, as some of the power levels were out of spec. A check was also done on all of the equipment internally and externally. The problem still occurred despite this. After waiting a month or so, I escalated again and a second engineer was sent. The second engineer confirmed the quality of all of the cables and connections, and that there were no apparent issues with my equipment according to their tests. They did check the cabinet and informed me that one of the connections in there was loose (not even finger tight) and that they had rectified that. Unfortunately, the problem has persisted. Ahead of posting this, I set up Broadband Quality Monitoring and waited for the issue to reoccur. This morning it has happened twice, which I believe is reflected there. I've attached images from today of an example of the issue in the logs, as well as the information from the router, the BQM and the results from SamKnows. Removed all IPs and MAC addresses in the images. Any help would be greatly appreciated as customer services have essentially told me there is no issue that they can see.Need Help from Virgin Team Please!
Hello, I continue to have issues. I think there's a problem with my Hub5 as a new customer. I can't play online games or stream at night, as internet usage seems to knock down my connectivity for a few minutes. Here's one of those spikes in action: Modem error logs as follows: Time Priority Description 29-04-2025 23:27:53 notice GUI Login Status - Login Success from LAN interface 29-04-2025 23:13:06 notice US profile assignment change.

I’ve noticed a few threads with issues around WiFi connecting to IPhones. I've been experiencing the same issues, however, my wife is on Android and having the same issue. We consistently have drop out on wifi with various apps buffering for ages. However, our Amazon fire stick seems to work okay. I’ve had two engineers out who can’t find any issues and even replaced the hub 5. It appears to work periodically, but will just stop and drop out frequently. I’m at my wits end as can’t find anything to resolve the issue. The last online chat resulted in Virgin sending us a WiFi booster, which I’ll try this weekend. As a last resort does anyone have any suggestions? We’ve had no issues for over a year, but something must have changed in the last 6 months as it’s complete hell now.Wifi and upload nightmare issues.
Across all our devices for the last 4 months wifi connected devices are intermittently not loading, they just drop off to mobile data or say connected no Internet. We are on the gig bundle. When doing Sam knows tests all looks fine but it's not. The engineers even experienced it when here. When doing speed test downloads speeds are fine but errors out on upload. Had 3 engineer visits, a new hub a new booster, One engineer said he found a ghost network. Even when all hubs etc where off still showing the network. It's driving us crazy, wifi tvs connect and seconds later lose the network again. As do all mobile devices, laptops etc... Any help or suggestions would be very much appreciatedNetwork issues still unresolved with no communication
How do you get an update on what VM is doing to solve network issues? in January there was a broader issue in our area where all of virgin media went out for a couple of days. Ever since then we have had nothing but network issues specific to our Internet, including latency spikes and drop packages to a point where the Internet will just stop working for periods of time. The virgin media website assessment tool also shows that this network intermittent signal issues related to our area all the time when you run it, but then says there’s no known issues in the area. After five engineer visits and then a complete replacement of all items from virgin media to our home, the last engineer spent an hour in the box on the street and worked out that there were numerous issues related still to the network. He was escalating the issue to the network team. That was well over a week and a half ago and still we are having the same issues and there’s absolutely no way to contact anyone at virgin media. To make the situation even more frustrating you can’t even raise a complaint on the virgin media website because that functionality doesn’t work. Short of simply changing providers which also includes television services how else are you meant to progress with this situation?Micro Internet Outages Every Few Hours
Hi all, All help greatly appreciated. Setup : Smart Hub 5 (modem mode) Issue : Every few hours my internet drops for approx 20-30seconds and then recovers. Observations : There is a lot of US profile assignment change logs. I think this are related to the times when my internet drops. "US profile assignment change. US Chan ID: 6; Previous Profile: 12 13; New Profile: 11 13.;CM-MAC=" Seen a couple of these in the current log. Nowhere near as prevalent "DHCP RENEW WARNING - Field invalid in response v4 option;CM-MAC=" Various errors logged (see screenshots below) What's changed? Have been running the Smart Hub 5 in router mode recently. Don't remember observing this initially but not 100% ruling it out. However, based on the Smart Hub logs it feels this is Smart HUB to Virgin infrastructure issues instead of it being my router plugged into Port 1 of the Smart HUB My next door neighbours recently has had Virgin Media broadband installed. Again I did not notice this initially so think again this is not related. System status : [Seems to be a lot of errors being logged such as] Adding upstream stats for reference And overall status Thanks in advance for any help or guidance
