Internet connection drops at random
We have a Hitron CGNV4 router running VM business—our home wifi is included in rent, therefore it's all under the letting agent's details. Over the past roughly two weeks we have been getting intermittent connection loss, usually for around a minute maximum, affecting both wifi and ethernet connections. It reconnects on its own but the disruption is long enough to disconnect us from calls and games. Some days it is pretty frequent, with 2-3 disruptions an hour, while other days we only experience one or two all day. I've done a power cycle on the router which has not fixed the issue. I've not yet tried a factory reset but having looked at some other people with similar issues that doesn't seem to have fixed it for them. I've also tried calling the business helpline but not been able to get through security (as it's under the agent's info, and despite me asking them they've not given me the account details I need). Would appreciate any advice on this to know if I could fix it myself or if we need to get a tech in.

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 ?Internet keeps dropping off for a minute or so
Hello! My internet keeps dropping off throughout the day for a minute or so, both wired and wireless. Tried support and got nowhere. The issue only appeared or started occurring after I upgraded my internet package and got the superhub 5. Support noted that i have had 72 disconnects in the month of june but have been unable to resolve my very frustrating issue. Here are the info from the network log on my router.

Thanks!Internet stops working once a day requiring a router reboot
Hi, I recently upgraded from volt500 to volt 1gig, which needed a modem change from hub3 to hub5. I use it in modem mode with my own router. Once a day now, the internet completely stops working, and I need to reboot the router by unplugging and replugging. After doing some searching, my 3.1 downstream channel is extremely weak. Channel ID Locked Status RxMER Data (dB) PLC Power (dBmV) Corrected errors (Active Profile) Uncorrectable errors (Active Profile) 159 Locked 32 -15.7 41903970 12674230 Can someone look into this?Complete Failure in Service
Hello, I am writing regarding the wifi at my house. We recently upgraded our broadband plan 3 or so weeks ago to the highest we can Gig1 service with a new hub 5 and it has been an abhorrent experience. For 3 weeks consistently there have been drops and disconnections from the internet. Too many times I have called regarding this. The internet went down about 5 times within an hour timeframe last Saturday and upon calling virgin to resolve this, your representative scheduled a technician to come today and I quote from the mouth of your representative “GUARANTEED” that our wifi problem would be solved. Not only was that a blatant lie, the wifi is now completely not connected to the internet, it is no longer intermittent on and off, it is completely off. Technicians have come twice to check connections install new routers and said everything should be fine but that is not the case. In addition, the house landline is no longer able to make calls and certain channels on the tv no longer show. NOT ONLY THAT, but I work from home! I have lost an entire day of work today due to virgin media’s poor service and I now must deal with the consequences with my superiors. The longer our virgin wifi is down the more my job is at risk! It is not just my livelihood that depends on good wifi, but my grandparents, who are both OVER 90 YEARS OLD and require reliable and fast wifi and service for communication in the event of a medical emergency, which is now at risk. What happens if there is a serious medical emergency in this heat and no one can call an emergency contact or an ambulance and it's too late? Shall I send virgin the funeral bill at that point? I demand a resolution to this immediately as we are paying the most and receiving less than the bare minimum. Should this matter not be resolved we will have no choice but to escalate this matter. I expect a response with hasteHigh Jitter & Packet Loss to Riot Servers
Hi, I’ve been experiencing “network problem” errors in Valorant despite stable ping and high speeds. I ran PingPlotter to Riot’s EU server (IP: 104.160.141.3) and noticed: 0% loss/jitter inside home network 100% loss and high jitter begins at hop 3 Speed tests show unstable throughput and ~23ms jitter This seems like a routing issue on Virgin’s side. Can this be escalated or checked? Happy to share logs or screenshots. Thanks!Extremely High Uncorrectable Errors – Major Connection Instability
Hi, We’ve been experiencing constant internet downtime and instability recently. After checking the status page on our Virgin Media Hub 5, I noticed extremely high uncorrectable errors on the DOCSIS 3.1 downstream channel, along with a low PLC power level that may be contributing to the issue. Here are the key stats: Router: Virgin Media Hub 5 Channel ID: 159 (OFDM) Locked Status: Locked RxMER: 36 dB PLC Power: -9.2 dBmV Corrected Errors: 721,981,898 Uncorrectable Errors: 113,766,705 The error count continues rising even after rebooting the router. We’ve already checked all cables and splitters inside the house—they’re properly connected and in good condition. Despite this, we’re seeing frequent disconnections, lag, and loss of service. Could someone from the team please investigate this? It feels like there might be a signal issue either at the street cabinet or on the line coming into the property. Happy to provide further data if needed. Thanks in advance, KellyIntermittent signal in your area.
I've had the whole day with no Internet as for some reason when I tried to do a status check I get a message saying intermittent signal in my area. There are no ongoing works in my area according to virgin website and my hub seems to be OK, as in there's no abnormal lights or signals showing. All my devices are connected to the hub however all of them say they don't have Internet access. I have tried tirelessly to get into a live chat but for some reason virgin make it near impossible to actually access this feature as it's nowhere to be found on their website which is why I've had to come here. I'm not waiting 24 hours for a possibility of my Internet returning like virgin are suggesting, I'd like access to the service I'm paying for. I'd understand if this work a planned works but as far as I'm aware it isn't.Routing Problems
Since about 9:30am this morning I've been unable to access certain websites. Google, MSFT Services and others work fine, but things like Facebook/Messenger, most news sites, speedtest.net do not load. This impacts all devices in my home - PCs, Laptops, Phones & Tablets regardless of if they are connected via WiFi or via Ethernet. The websites load fine on phones & tablets when using a mobile data connection. I've tried to contact Virgin support via the status page but I was told there is nothing wrong with my connection. Yet I still can't access certain websites. How might I go about reporting routing problems and getting them addressed? (I've also reposted this thread as my original report appears to have been deleted??)
