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. – KHub4 connection and can’t speak to anyone. Hung up on 3 times by the robot 🤷♂️
Anyone have connection issues in the Preston area this morning? We have our alarm connected over WiFi and as it’s died in the night now have no easy way to disarm it. Rang virgin 3 times and been hung up on saying they’ve sent a text but yet no text received and can’t get to a human! Anyone any ideas on how to get hold of a person at virgin media? Worst customer experience ever!
Gaming lag on Hub 4 with 250Mb service
Good evening, I've been seeing occasional packet loss on my connection and friends say I am lagging in games. I'm on a 250Mb service with a Hub 4. The speed is usually OK but can drop right down at times to below 10Mb upstream (normally it's 25Mb upstream). I'm connected from the PC to Hub with an Ethernet cable. I looked at the Hub stats which I've posted below. 3.0 Downstream channels Channel Frequency (Hz) Power (dBmV) SNR (dB) Modulation Channel ID 3 154750000 5.599998 38.983261 QAM256 3 1 138750000 6.900002 38.983261 QAM256 1 2 146750000 6.300003 40.366287 QAM256 2 4 162750000 5.000000 38.983261 QAM256 4 5 170750000 4.599998 38.983261 QAM256 5 6 178750000 4.099998 38.983261 QAM256 6 7 186750000 3.799999 40.946209 QAM256 7 8 194750000 3.500000 40.366287 QAM256 8 9 202750000 2.900002 40.366287 QAM256 9 10 210750000 2.500000 40.946209 QAM256 10 11 218750000 1.799999 38.983261 QAM256 11 12 226750000 1.299999 38.983261 QAM256 12 13 234750000 1.000000 38.983261 QAM256 13 14 242750000 0.799999 40.366287 QAM256 14 15 250750000 0.799999 40.946209 QAM256 15 16 258750000 0.799999 40.366287 QAM256 16 17 266750000 0.400002 40.366287 QAM256 17 19 282750000 -0.299999 40.366287 QAM256 19 20 290750000 -0.599998 40.366287 QAM256 20 21 298750000 -0.700001 40.366287 QAM256 21 22 306750000 -0.700001 40.366287 QAM256 22 23 314750000 -0.700001 40.366287 QAM256 23 24 322750000 -1.099998 38.605377 QAM256 24 25 330750000 -1.200001 40.366287 QAM256 25 26 338750000 -1.500000 38.983261 QAM256 26 27 346750000 -2.200001 38.983261 QAM256 27 28 354750000 -2.900002 38.983261 QAM256 28 29 362750000 -2.900002 38.983261 QAM256 29 30 370750000 -3.000000 38.605377 QAM256 30 31 378750000 -3.500000 38.605377 QAM256 31 32 386750000 -3.599998 38.983261 QAM256 32 3.1 Downstream channels Channel Channel Width (MHz) FFT Type Number of Active Subcarriers Modulation (Active Profile) First Active Subcarrier (Hz) 33 96 4K 1840 QAM256 759 3.1 Downstream channels Channel ID Lock Status RxMER Data (dB) PLC Power (dBmV) Correcteds (Active Profile) Uncorrectables (Active Profile) 33 Locked 28 -20.2 1565054768 115 3.0 Upstream channels Channel Frequency (Hz) Power (dBmV) Symbol Rate (ksps) Modulation Channel ID 1 30100000 37.020599 5120 KSym/sec 64QAM 4 2 43100000 37.770599 5120 KSym/sec 64QAM 2 3 36600000 37.520599 5120 KSym/sec 64QAM 3 4 23600000 37.020599 5120 KSym/sec 16QAM 5 5 49600000 38.270599 5120 KSym/sec 16QAM 1 3.1 Upstream channels Channel Channel Width (MHz) Power (dBmV) FFT Type Modulation 6 10.4 42.1 2K QAM128 3.1 Upstream channels Channel Channel Type Number of Active Subcarriers First Active Subcarrier (Hz) T3 Timeouts T4 Timeouts 6 OFDMA 208 53.4 5 0 Does anyone think I need to arrange an engineer for these stats please? Only things I can see is roughly a 10dB variance as the power trails off on the downstream channels and the upstream can't maintain 64QAM on all channels. From the main cable in from the road, there is one splitter with two outlets. One is for this Hub 4 and the other for a V6 TV box in another room. That's it. I walked around the house and the cables look in good condition. All connectors are snug on the screw terminals. TV channels seem OK. I'd be very grateful for any advice please. Thank you for reading.Virgin 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.

I’ve got a new Roberts Revival radio that I can connect to our Virgin Hub 4, but despite connecting to the WiFi network, the device seems to not be able to connect to the internet. This is isolated to this one device, all other devices connect to the Virgin WiFi and internet perfectly fine and I’ve never had this issue with any other device so unsure what could be going wrong. The device is able to connect to the internet fine when I use my local iPhone hotspot WiFi, or connect to one of our BT WiFi extender discs so assuming it’s something specific to the way in which the device is interacting with the Hub but can’t for the life of me work out what might be going wrong! Any advice would be much appreciated, I’m very much a rookie at diagnosing with WiFi and internet network issues.
