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.Perceived 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.VM Connect App Cannot Find Hub 4
My VM Connect App cannot find my hub 4. I am running the latest version of the app on iOS 17.5.1 I have tried following the instructions on related forum posts, such as resetting my hub, clearing the app data and removing my VPN connections, but the issue still remains. Last week I raised a first line support ticket with Virgin Media over the phone but nobody has followed up. This is incredibly infuriating and I can't bear the thought of calling VM to describe the problem to the support team who do not understand the VM Connect issue that I’m experiencing. Please help resolve the issue as I’m unable to review or test the efficiency of my Virgin Media service.VM connect not connecting to hub 4
Hi, my hub was installed by the engineer months ago, but it never connected to the app. I contacted Virgin as our internet has been a bit laggy and they sent a new hub4. This one also won’t connect to the app. I’ve tried deleting the app and reinstalling etc and I just get “hub not found”. When I go to 192.168.0.1 the page doesn’t load. I’ve tried reading through these posts as it seems loads of people have issues but I don’t know what else to do. Customer service suggested that I contact the “chat” for some assistance, and they are sending me another pod. But with my hub and pods not connecting to the VM Connect app, I just don’t know what else to do…
