Connection keeps dropping Critical
Connection keeps completely dropping randomly for a minute every couple of minutes. I have turned off the router for a couple of minutes and turned it back on many times.

Internet and TV drop out since December
I’m hoping someone from Virgin Media can help as this issue is still ongoing. My broadband and TV services have been repeatedly dropping out since the end of December. An engineer attended on Saturday (after I waited in for the appointment) and advised that there is a signal issue affecting my property and the four neighbouring houses. I was told this was a known fault and that it would be fixed right away. Unfortunately, nothing has changed and the broadband and TV are still dropping out just as before. This has now been going on for several weeks and is extremely frustrating. We have kids in the house and they are going crazy without a reliable internet connection, especially when the issue was already acknowledged as an area-wide fault. Can someone please: Confirm what the fault actually is Advise when it will be properly resolved Confirm whether this has been logged as an area/network issue Happy to provide account details via private message if needed. Thanks.77Views0likes1CommentPS5 suddenly stopped connecting to WiFi
Has been ok for a year on the network and now saying this “Can’t connect to the server within the time limit. There might have been a problem in connecting to the network, or PlayStation Network or the server of the service provider might be temporarily busy”116Views0likes4CommentsBook engineer to check network
Hi, I am having trouble with my internet. It randomly drops out. I have 1gig internet, and intermittently it will drop to 30mbps. Resetting the router fixes it, however when I unplug the router, and plug it back in - it doesn’t connect to the internet. I have left it hours and it doesn’t ever connect. I can connect to the router, but the router doesn’t have internet. I have to unplug it a further 2-3 times, before it will connect to the internet. I did a network self test and it identified the router couldn’t connect with VM servers. An engineer came and replaced the router which didnt fix the issue. The engineer said somebody would have to come and take a look at the cabinet if replacing the router doesn’t fix it. How do I get an engineer to look at the cabinet please? When it happens, these are the error messages: SYNC Timing Synchronization failure - Failed to acquire QAM/QPSK symbol timing;;CM-MAC=(redacted);CMTS-MAC=00:00:00:00:00:00;CM-QOS=1.1;CM-VER=3.1; And when the internet is working but drops out randomly I get the error - DBC-REQ Mismatch Between Calculated Value for P1.6hi Compared to CCAP Provided Value My postcode is ME20 Thank you69Views0likes2CommentsBoardband service is keeping unstable / disconnected
I’m living in postcode B90. During these months ,the boardband service was keeping unstable. The service was keeping on and off especially on Sat, Sun or Public Holidays. It’s totally disappointed. Is that the services demand over load the server ?48Views0likes1CommentYealink sip-t64u help needed urgently!
Hey all, My wife uses a Yealink sip-t64u phone to work remotely. It used to work for weeks at a time, stop for a while and then take weeks to work again. We had a Hub 3 and plugged the phone into a TP-link extender via ethernet cable. Recently the phone stopped working (the extender and phone were accidentally switched off) and it hasnt come back. We spoke to Virgin who upgraded our broadband speed to 1gb and we now use a Hub 5. We set it up today by plugging it in to the router via ethernet cable and initially it worked. We moved the phone upstairs and used our TP link extender and again, success. Foolishly we unplugged the extender and phone so we could better organise her desk and now the phone says service unable once again. Strangely when we plug the phone into a Virgin router at my sister's house, the phone works and ditto when it is plugged in at the office. We are at our wits end and I'm desperate to get this sorted. I've read that Virgin hubs are notoriously bad at enabling VOIP phones to work. I've also read that putting the hub into modem mode and using our own router is the way to go but we have no idea which router would work. We even have a Virgin technician booked to come and have a look om Wednesday but I fear this won't help. Please help, kind strangers!173Views0likes12CommentsNo internet and intermittent internet since 13 November
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.61Views0likes1Comment
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.176Views0likes4CommentsEPH Gateway compatiblity
I have an EPH gateway used for controlling my heating via WiFi, and have used it for 3 years without issue. About 3 months ago it started dropping off the internet and after 3 or 4 visits the engineer suggested I contact EPH who suggested the issue may be something to do with the Virgin Media WiFi ? The did send me another gateway unit just in case, and that has been installed with no improvement. So the question I have is, could the WiFi signal be the problem? I should add that we have no other issues with anything at all connected to the WiFi, and the signal strength seems fine. TIA.163Views0likes7CommentsConnection 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?95Views0likes2Comments
