Constant problems, zero solutions.
So I've had intermittent problems over time. RCS Partial Service, Sync Timing, No Ranging Response. I know this is a problem with the box outside. How do I know? They've replaced the hub, the cabling in and out of my home, and rebooted everything so many times I just say I have at this point. The issue isn't my hub, it isn't the connections, it isn't the damn wifi as it's hard wired, it isn't the devices, it's outside. The box. Can someone tell me exactly how to get this issue raised to the right people, who will actually fix it, and not have to sit through 10-20 minutes of the most boring, mundane copy/paste directions and days waiting for another engineer to change nothing?We can't find your Hub Looks like we've lost connection. Please try installing again.
Vm connect won’t connect to my hub. Tried reinstalling but still not connecting. Uninstalled the app and tried again but still the same. Happened last week when I rebooted my hub and pods, since then it won’t connect. Any ideas pleaseUpstream power too high?
I've been having connection drop-out issues for the past few months (~180 reconnects within the last month according to VM, though I only saw a drop 1-2 a day for 5-90 mins at a time). I'd been mostly away from home so didn't bother about it until this week, when VM sent out an engineer to investigate (10th July). The engineer removed an old NTL attenuator/splitter, along with the splitter for the broadband and TV (as I plan to ditch the TV). He also switched out my Hub 3 for a Hub 5, which has an inline attenuator on its cable feed. Annoyingly I didn't note the full line stats before the changes, but the engineer said the downstream was reporting as -8 dBmV, and after these changes is now 0 to -5 dBmV with an SNR of 40 dB. I'm still having drop-outs (and T2 and T3 timeouts), though less frequent (1 time a day for 1-5 mins at a time), and from doing some research I suspect my upstream power is still too high. It's currently sitting at 52 dBmV, but I've seen it get as high as 59 dBmV immediately after the modem reconnected (it drops back down to 52 dBmV over a span of ~20 mins once the connection is back up). I just wanted to confirm my understanding is correct before requesting another engineer visit to correct the upstream power. I tried to add the full line stats and log into this post, but the forums report "Your post contains invalid HTML." if I do... that used to work.Intermittent connection issues
For the last couple of weeks, few times per day my internet completely drops for short time (usually less than 1 minute), and after that all is back to normal. This happens at completely random times - there are days when it doesn't happen at all, and other days when it happens several times. Once that happens VM service status page shows "Intermittent signal in your area", then it changes to "You need to book an engineer", and then it's back to "No broadband issues" (until next disconnect). The engineer came last week, he checked the wiring, signal, etc., and didn't find any issues on my side. He also replaced my Hub 3 with new Hub 5. Unfortunately the issue keeps happening after that. Here you can see how these drops look: Every time when these issues happen, the network log in the Hub shows multiple 'critical' entries such as: No Ranging Response received - T3 time-out 16 consecutive T3 timeouts while trying to range on upstream channel Received Response to Broadcast Maintenance Request, But no Unicast Maintenance opportunities received - T4 time out SYNC Timing Synchronisation failure - Loss of Sync Could someone from VM have a look and help please? 3.0 Downstream channels Channel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID 1 330000000 6.4 41 QAM 256 25 2 138000000 4.7 40 QAM 256 1 3 146000000 4.9 40 QAM 256 2 4 154000000 4.9 40 QAM 256 3 5 162000000 4.9 40 QAM 256 4 6 170000000 4.9 40 QAM 256 5 7 178000000 5 40 QAM 256 6 8 186000000 5.1 40 QAM 256 7 9 194000000 5.3 40 QAM 256 8 10 202000000 5.2 40 QAM 256 9 11 210000000 5.3 40 QAM 256 10 12 218000000 5.4 40 QAM 256 11 13 226000000 5.4 40 QAM 256 12 14 234000000 5.5 40 QAM 256 13 15 242000000 5.6 41 QAM 256 14 16 250000000 5.6 41 QAM 256 15 17 258000000 5.7 41 QAM 256 16 18 266000000 5.6 41 QAM 256 17 19 274000000 5.8 41 QAM 256 18 20 282000000 5.9 41 QAM 256 19 21 290000000 6.2 41 QAM 256 20 22 298000000 6.3 41 QAM 256 21 23 306000000 6.3 41 QAM 256 22 24 314000000 6.4 41 QAM 256 23 25 322000000 6.4 41 QAM 256 24 26 338000000 6.5 40 QAM 256 26 27 346000000 6.7 41 QAM 256 27 28 354000000 6.7 41 QAM 256 28 29 362000000 6.9 41 QAM 256 29 30 370000000 6.9 41 QAM 256 30 31 378000000 7.1 41 QAM 256 31 3.0 Downstream channels Channel Locked Status RxMER (dB) Pre RS Errors Post RS Errors 1 Locked 41 2166 7079 2 Locked 40 4100 9616 3 Locked 40 4414 15176 4 Locked 40 8311 44157 5 Locked 40 8257 42752 6 Locked 40 8282 46018 7 Locked 40 3734 9961 8 Locked 40 4150 15136 9 Locked 40 2425 6338 10 Locked 40 5829 26867 11 Locked 40 2236 5521 12 Locked 40 1792 4249 13 Locked 40 2056 4722 14 Locked 40 7266 38180 15 Locked 41 2715 12483 16 Locked 41 2280 11454 17 Locked 41 2364 6014 18 Locked 41 2569 9438 19 Locked 41 1924 6029 20 Locked 41 3257 15859 21 Locked 41 1596 4954 22 Locked 41 1679 4609 23 Locked 41 2012 5221 24 Locked 41 3982 22531 25 Locked 41 1646 4652 26 Locked 40 1828 7782 27 Locked 41 1880 7241 28 Locked 41 1724 6518 29 Locked 41 2106 10214 30 Locked 41 1932 8377 31 Locked 41 1543 5268 3.1 Downstream channels Channel Channel Width (MHz) FFT Type Number of Active Subcarriers Modulation (Active Profile) First Active Subcarrier (Hz) 33 92 4K 1800 QAM 4096 1128 3.1 Downstream channels Channel ID Locked Status RxMER Data (dB) PLC Power (dBmV) Corrected errors (Active Profile) Uncorrectable errors (Active Profile) 33 Locked 41 6.3 238950482 76 3.0 Upstream channels Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID 0 49600000 51.5 5120 QAM 64 1 1 43100000 51.5 5120 QAM 64 2 2 36600000 52 5120 QAM 64 3 3 30100000 52.3 5120 QAM 64 4 4 23600000 52.8 5120 QAM 64 9 3.0 Upstream channels Channel Channel Type T1 Timeouts T2 Timeouts T3 Timeouts T4 Timeouts 0 ATDMA 0 46 0 0 1 ATDMA 0 46 0 0 2 ATDMA 0 46 1 0 3 ATDMA 0 46 0 0 4 ATDMA 0 46 0 0 3.1 Upstream channels Channel Channel Width (MHz) Power (dBmV) FFT Type Modulation 12 10.4 46.5 2K QAM 256 3.1 Upstream channels Channel Channel Type Number of Active Subcarriers First Active Subcarrier (Hz) T3 Timeouts T4 Timeouts 12 OFDMA 208 74000000 0 0External cable rerouting
Good afternoon, There is a Virgin phone line attached to my fascia boards but I am having them replaced next week. The installers won't do it, BT can't because it's Virgin's cable, I've tried to get a Virgin engineer out to move it but have got nowhere with calling support or using the chat service. Can someone please help? SeanInternet 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 ?Moving address flashing green light....
Hi, the experience of moving house is hard enough as it is and then you have to spend a whole day trying to get everything working to which you are constantly being told by a robot that your account number is wrong and then that they can't text your number for pointless reasoning this is ridiculous... I have moved house i followed the instructions on the moving house booklet front virgin media and it's not working I have a flashing green light at the bottom... I have tried everything suggested and when trying to call apparently my account number is wrong and it won't proceed half the time when it does they say they can't message me and hang up.... when trying to do the connection stuff that is on the website it does it for the previous address....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.
