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.

Hub 3 needing reboot frequently
I have the M500 broadband package and a Hub 3 router which I understand is currently being replaced by Virgin Media with the Hub 5 router. Apparently speeds of 500mb are at the limit of this router. I think my router is now struggling as I have to reboot it every few days as it seems to lose its connection with my tv box and my Firestick. Rather than wait for "my turn" for an upgrade, how do I get hold of a new Hub 5 asap? I have tried the "web chat" but can't get to speak to a real person and I don't want to spend ages on a call. Any help will be appreciated.
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.Book 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 youBoardband 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 ?Hub 3 constant red light
My virgin hub 3 router has a constant red light on the front for the past 3 months. I have followed all the reset instructions and move its location but it has made no difference. It also regular closed WiFi signal to the TV boxes. Having read this fourm it looks like it needs replaced but I cant get trough the self help guides to speak to a rep on the issue. Can someone please help here? Thanks James
EPH 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.Solid redline on my hub3
