HUB 4 connection/reboot issues
Anyone having problems with HUB 4? Had the same router for some years so probs about ready for a replacement but during the night the internet went down, don't know if my end or VM but all equipment was left on when leaving for work. Came back to HUB still going through rebooting sequence. Tried the usual reset, power down etc. Lights seem to be as they should during reboot except a blue flashing light which is WPS not normal. The reboot never seems to end and keeps a circular continuous sequence. Engineer called but earliest is 48hrs, any ideas would be gratefully received. CheersHUB 4 loosing Internet connection
Since today having issues with HUB 4 : I use it in modem mode (been like that for over a year, never had issues). This morning noticed not any device could access internet . Rebooting the HUB sorted the issue for a couple of hours then issue appeared again. So every couple of of hours the HUB needs rebooting. I tried to log into the HUB (wired) i spotted a strange ip assigned to my device in 169.254.xx.xx, and i could get to the admin page via HTTP. after reboot it went back to 192.168.100 and could log in. The hub keep its green light all the time, like there were no issues. What the hell is going on, why the hub is doing that?
Wifi takes forever to start up
Every time I restart my Virgin Media Hub 4, it takes about 5 minutes to get the steady white light back. Then it takes a further 15 minutes to get a 5GHz wifi signal back. Until then, nothing. I would chat to customer services, but chat doesn't work on my laptop. Still, YouFibre has just started operating here so they might be a better bet!Hub 4 - Flashing yellow/blue light, no internet connection.
My internet has been down for a six days now. Last tuesday I came in and the hub, it's a hub 4, was flashing a yellow light. I checked the area's report for issues and it said there was one ongoing. The following day it went to a red light and has been that way all weekend. I've been getting updates on the issue via text and it reported as fixed today, six days later which is bad enough, but I came in and re-started my hub and it's just back to the yellow light again with no internet connection. If left alone the yellow light will eventually turn into a flashing blue light instead. When I log into the hub itself it says the hub has an internet registration failure. Am I going to need an engineer here?Hub 4 TLS Latency with Firewall Enabled (Firmware 01.04.092.07.16) — Consistent 5s Handshake Delay
Posting to document and seek advice on a consistent issue I’m experiencing with a Virgin Media Hub 4 running firmware 01.04.092.07.16.EURO.PC20. Summary of Fault: When the firewall is enabled on the Hub 4, there is a consistent 5+ second delay during the TLS handshake phase for HTTPS connections. This occurs on all sites and has been replicated using curl, browsers, and diagnostic tools across multiple devices. When the firewall is disabled, TLS handshake times return to normal (100–200 ms), and all delays disappear. This behaviour is identical to the one reported in Community Thread ID 5475086, which attributes the issue to firmware 01.04.092.07.16 and confirms that it is resolved in firmware version 01.04.100.xx.xx.EURO.PC20 or by switching to a Hub 5. Technical Diagnostics (example curl results): With firewall ON: DNS lookup : 0.006204s TCP connect : 0.006792s TLS handshake : 5.094022s Server proc. : 5.152472s With firewall OFF: DNS lookup : 0.010297s TCP connect : 0.011480s TLS handshake : 0.103843s Server proc. : 0.151060s No DNS changes or browser settings affect this. The delay is introduced at the router level and consistently impacts every HTTPS request. Actions Taken: Factory reset of the Hub 4 Wired and wireless testing across multiple machines Replicated issue on different OS and network stacks Rebooted between firewall toggles What I Need Help With: Can anyone confirm the latest firmware version for the Hub 4 and whether they’ve received 01.04.100 or higher? Has anyone else on M350 or below had this resolved via firmware push or Hub 5 swap recently? Can any Virgin Media staff confirm if this fix is being actively rolled out or applied on request? Complaint reference already raised: C-0506256775 Thanks in advance to anyone who can shed more light. Happy to provide additional logs if useful. – KVirgin Media Hub 4 in modem mode and DrayTek Router. Frequent reboot.
Good afternoon All, After spending a horrible weekend trying to troubleshoot a sporadic reboot of my DrayTek router, sitting behind a VM Hub 4 in modem mode, decided to share something, which might help others in the same situation. In short the setup is: Virgin Media Hub 4 in modem mode serving as a gateway for a DrayTek router handling all home routing and services. Exhibit of the problem: eratic and unexplained reboot of the DrayTek router every 5 - 10 minutes since Saturday 22nd of March 2025 After spending hours of trying to troubleshoot the issue by checking every single node on my network and disabling individual segments, applying various of severe firewall rules etc, I concluded that the problem is due to the DrayTek router being connected to VM Hub 4 sitting in modem mode. This way the DrayTek router is directly exposed to the internet. Having a long conversation with the VM Support team, didn't bring much joy or solution. I ended up switching off completely the DrayTek and quickly setting up the VM Hub 4 in router mode and leaving it like that. This seems to have resolved the problem with the reboot naturally as DrayTek is off the game. However, it kept me uneasy, why after 4 months of perfectly working, this issue appeared out of the blue. Is it the DrayTek, is it the VM Hub 4 or is there anything else. I have had no changes implemented in my network for months, therefore I excluded the possibility of a configuration to be leading to this. I was confused untill an hour ago, when I came across an article announcing a probable attack on DrayTek routers around the world: https://www.ispreview.co.uk/index.php/2025/03/broadband-isps-report-uk-connectivity-problems-with-vulnerable-draytek-routers.html This explained it all! There seems to be a vulnerability in the DrayTek routers that has been exploited and it is not just in UK but worldwide. Therefore, if you are experiencing any strange outages of the service, reboots of your router or other suspicious behaviour of your router, especially if it is DrayTek and sitting behind VM Hub in modem mode, before ringing VM support, check the above article and try to neutralise this vulnerability. I am currently in the process of trying to patch the DrayTek router and see if that would resolve it for me. Needless to say that DrayTek's website is currently experiencing issues, perhaps due to volume of requests, but be patient and try to implement whatever you can from the suggestions in the article. Best Regards IanPerceived Hub 4 Wi-Fi strength degradation
Hi - been using Hub 4 for about a year now, and until recently its Wi-Fi strength in all but the furthest locations of my house has been robust and stable. I'm running a combination of 2.4 and 5Ghz devices, with the 'cleverer' ones achieving dual-band. The hub's Wi-Fi signal is in default configuration, with Enable Channel Optimization enabled and channel selection is automatic for both frequencies. No complaints until maybe a month or so ago, when my Win 11 laptop that usually sits upstairs in my office started to become unable to stably handle the usual Teams calls, screenshares, etc. Meanwhile other 2.4Ghz devices in the same room as the Hub 4 will briefly go offline from time to time. The Hub has always remained in the same place - albeit behind the TV - and yes berate me for this - but it's been absolutely fine there for my needs. The Hub 4's Wi-Fi troubleshooting capability is pretty much nil and as a last measure have just resort to reserving all of the c.25 devices' IP addresses and increasing the lease time to 7 days to help cut down on DHCP chatter. Its temperature is always hot to touch but the diagnostic tool doesn't complain. I'm looking for options now - I don't think Pods will solve this problem, I've used a similar TP-Link solution and wasn't particularly impressed. Should I look to invest in my own wireless router and switch to Modem mode or should I seek to have an upgrade to Hub 5 with its stronger Wi-Fi 6 capability? Any advice welcome.
Hub 4 with no RF Signal after thunder storm
Just had a thunderstorm, and after what seemed like a very close bolt of lightning, my internet cut out. The Hub 4 said 'No RF Signal Detected', and eventually a red flashing light. I had tried powering it off again 4 times. No luck. I spent 90 minutes on the phone, being passed around to 4 different people, all just going through their script. Even trying to get advice on where the Hub backup / restore option was, was met with confusion and passing me on to someone else. Very frustrating. Eventually managed to do a factory reset. Still no luck. The last agent on the phone was telling me she was sending data to my Hub and getting a response, but I don't see how that is possible with no RF being detected my end. This has happened once before, is it just bad luck, or has my cable been installed incorrectly and this is likely to happen again? Any ideas how I can get back online? We do have an engineer coming over the weekend, but obviously would like to resolve this sooner if possible. For now I've just unplugged the Hub and going to try it again in an hour or so.
