Factory Resetting of Hub3
Hi I have just swapped out my hub3 and successfully installed a hub5. Because I was concerned I might have issues, I deliberately did not factory reset my hub3 before disconnecting, just in case I had problems with the hub5 install and needed to roll back. I have since powered up my old hub3 and without connecting it back up have simply pressed the reset button for 30 secs. It then appeared to go through a restart and what could be a reset sequence but instead of eventually showing a solid white light (which I’ve read elsewhere is what happens at the end of the reset) the green WiFi light and light at bottom flash green…. I left it for over an hour and it continues to flash green - not a solid white light. Presumeably it’s flashing green because it can’t find any network (because I’ve not connected it back up). My question is: How can I be sure the factory reset has been successful? I don’t want to send it back to Virgin before I’ve removed my personal settings/device connection details etc… I’ve not attempted swapping it back in as I don’t want to mess up my hub5 activation in any way. Thanks in advance for any info you can give.Virgin Media Area Outage loop - N11 London
I’m at my wits’ end with Virgin Media. For over two months (since 31st May 2025), my broadband has been cutting out regularly. Every time I call or try to book an engineer, I get the same answer: They give a repair date, then either “fix” it for a day or two before the same fault pops up again — sometimes under a new fault ID — and the loop starts over. I went through my text alerts from Virgin and found a ridiculous chain of fault updates. Here’s the pattern just for this summer (those are only the alerts one, there were more in between those): 31 May – 12 June: Fault F011810225 — multiple repair date pushes, “engineer on the way,” “engineer on site,” then “issue fixed.” 24–25 June: Fault F011877105 — same story, marked as fixed. 21 July-25 July: Fault F011910493 . 25 July-31 July: Still issues and an operator ordered a replacement modem which did not solve the problem 3 August: Booked an engineer to fix this issue but this got cancelled for the area fault updated status 3–15 August: Fault F011937562 — constant shifting repair dates (5th, 6th, 8th, 13th, 15th), marked fixed… 15 August (Ongoing): The status has been (Fix( reset but there is intermitting issue when I check the website and I am sure it will re-loop Each “fix” lasts a couple of days at most before it’s back to square one. I’ve even had a technician appointment booked, then cancelled because it was supposedly “a network issue.” This has been going on for over 10 weeks now. I can’t get a proper engineer visit to my property. The “area fault” excuse keeps resetting the clock. Compensation is unclear unless I push for it. I cannot terminate the contract without paying for the exit fee Has anyone else had Virgin keep re-flagging the same problem as “new” to avoid escalation? How did you get them to actually fix the infrastructure, or at least give you consistent service? I’m considering filing a formal complaint and escalating to CISAS, but wanted to see if others have broken out of this loop before.
Dreaded Red Light On Hub. Useless Phone support.
I've had the dreaded constant red light on the Superhub 3 I have had for some years for at least two weeks. It may have been longer. After reading the advice given here I have tried all the possible solutions numerous times - 3 pinhole resets and even leaving the hub unplugged for an hour or so before restarting. Nothing removes the constant red light. I have experienced a couple of episodes of poor internet speeds and a brief outage - as low as 70 mbps on my Volt 500 package - but these have been intermittent. It was actually an episode of low speeds that caused me to notice the red light and read the forum threads on the issue in the first place. These threads have all resulted in the same advice from members and mods that the light indicates a potential overheating fault and the device needs to be replaced. I have spent a frustrating three or four days attempting to get this resolved over the phone, repeatedly being cut off mid-call. I have just ended a long call with a Virgin media telephone CS assistant - the third one I have called today, with the first call being made about four hours ago. They advised me that since their remote diagnostics show no issue with my connection that they cannot replace the hub. Unless the contradictory advice given numerous times on this forum is nonsense this is very alarming. I don't see how Virgin can rule out a potentially dangerous overheating fault simply by conducting remote diagnostics and then provide me with no alternative explanation for the sudden appearance of the constant red light. There must be a reason it has suddenly appeared and if there is any possibility it indicates a potential overheating issue how is this refusal to address the issue or explain why it has occurred supposed to leave me with any peace of mind? I am now faced with the prospect of unplugging my hub at night, or whenever I leave the room for any length of time just to achieve some degree of reassurance. As I explained I have carried out a pinhole reset three time and left the hub unplugged for a long time. There is no issue with ventilation. It has been in the same location for as long as I have had it - as I recall I received a Superhub 3 soon after they were first rolled out. Any advice will be gratefully received!Broadband Dropouts - slow speed– SYNC Timing Errors
I’m experiencing ongoing broadband dropouts that closely resemble the issues described in the following community threads: Broadband connection keeps dropping SYNC Timing Synchronization failure – Loss of Sync My Virgin Media Hub is currently operating in modem mode, and I’m using an ASUS GT-AX11000 router to manage my home network. The dropouts affect both Wi-Fi and wired (LAN) devices, including critical appliances connected directly to the router. Symptoms include: Sudden and repeated loss of internet connectivity across all devices Devices remain connected to the router but lose access to the internet Dropouts occur randomly, sometimes multiple times per day Router logs show normal operation, suggesting the issue is upstream Given the similarity to the SYNC Timing Synchronization failures described in the community posts, I suspect this may be a signal-level or infrastructure issue. I’ve already: Verified all coaxial and Ethernet connections Updated router firmware Monitored logs and confirmed no local faults Could you please: Review the line signal levels and error logs from your end Confirm whether SYNC or RCS errors are present on the hub Advise if an engineer visit is required to inspect the line or cabinet I’d appreciate your support in resolving it promptly.

Hub 3.0 Solid Red Light
Hi all, I think this is a fairly common issue but my Hub 3 router (in modem mode) has had a solid red status light now for a few weeks but I hadn't noticed any issues so not bothered about it. However, yesterday and this evening I have noticed WiFi issues from the WiFi router connected. If have checked the WiFi device (TP Link X55) and that all appears fine. Yesterday it was down to sub 1MB though. I have tried the turn off and on again approach and tried resetting but the red light persists. Anyone have any other options? Thanks all.Hub 3 hot weather no Internet
Hi, during hot weather(25°+) my hub 3.0 led shows a steady red and the internet goes. It only comes back on when the weather/temp cools down. This consistently happened every hot weather day the last few weeks. I've had my hub 3.0 about a decade now but this is my first time with this issue. Service status for my area always shows as good. I check all connections and reset everytime but it only works for a min then it goes again. The only thing that solves it is waiting for the weather to cool🙁. It's been in the same spot with lots of space around it for years without issue until now.
