Intermittent broadband, latency issues, packet loss
Hello. I have been with virgin broadband for about 8 months now and I have had nothing but an intermittent service. It is beyond frustrating as I have sky stream and suffer from streaming issues all the time. I have set up a broadband quality monitor since June and it clearly shows high latency issues and dropped packets all the time. I have had visits from two engineers that have changed the cables inside my property and outside but the problem persists. i have no idea what to do now and I am desperate for help. This BQM is a typical example of what I have faced daily since joining Virgin Media.Ping, Latency & Packet Loss
Just a question about this really. My minimum latency sits around 18 or 19ms on a ping graph but I’ve seen others connections a lot lower about 10ms or even a bit lower. Is this based on how far you are from the exchange / cable box on the street or local area connection? The think broadband monitor graph shows the main min area in green, just interested how it works and how some people show it much lower. My connection seems fine but this past week seen a lot of dropped packets on my graph but seems to show every other day or so. Can you check if there’s any issue on the line happening? I’ve done a check and it says my home network has a few problems with a Red triangle next to the broadband bit, all the others are normal in Green. PS: I use both Ethernet & Wi-FiPing spikes since switching to VM and can't get through to anyone
Switched to VM in NOV 2024 on 18 month contract (M350) and get short ping spikes, spikes to anywhere between 100ms and 1000ms for like half a second then comes back down, every minute or so. Dealt with it for a few months maybe thinking it was just because I think VM recently became available in my area but now its just getting obnoxious. Past 2 weeks connection has been fully dropping for 5 to 30 minutes at a time at least once a day. Set up a BQM on thinkbroadband.com quite a while ago. Tried to call, can't get through to a human being. Can't chat to anyone online now because all it say is theres an issue and they are dealing with it but when it gets to the resolution date it just changes the date to the next day. Just would like any input on what I can do, don't want to pay cancellation fee but cant get through to anyone and would like to know whats going on in my area as others on VM in other places are fine.

Hello, Im a customer of roughly 10 years+ and I’m experiencing ongoing broadband performance issues with Virgin Media since January 2025, including high latency, packet loss, and inconsistent speeds across both wired and wireless devices. This has made basic internet use — like streaming, using virtual desktops, or even signing into websites — extremely unreliable. Despite: • 3 engineer visits • A new router • Countless phone calls and promises …the issue is still unresolved. Third-Party Diagnostics: I had a third-party company run diagnostics, including a traceroute. Their analysis showed: • Data travels smoothly until reaching Virgin Media’s Luton data centre • From there, it appears to hit a problem with overloaded infrastructure or routing before reaching my home. • The traceroute could not even complete beyond Luton, indicating serious issues in the Virgin Media network itself They confirmed that the fault appears to lie within Virgin’s internal routing and node load balancing, and not with anything in my home setup. Complaint Handling Issues: This has been escalated through Virgin Media’s complaint process — but their handling of the complaint raises serious concerns: • A manager promised I could send in my diagnostic evidence via email — but never followed up • Another manager claimed engineers could “re-route” data to avoid congestion — this never happened • Virgin Media has closed my complaint without my consent, even though it remains unresolved • They have told me to wait up to 28 days for a deadlock letter, preventing me from escalating the issue to the Communications Ombudsman • They promised the 3rd engineer could re-route data, but he didn't Ofcom General Condition Violations: This handling may constitute a breach of the Ofcom General Conditions of Entitlement, including: • GC C4.5: A provider must not close a complaint unless the customer agrees it is resolved or they issue a deadlock letter • GC C4.8: Providers must not unduly delay issuing a deadlock letter • GC C4.1–4.4: Sets expectations for fair, accessible, and efficient complaint handling Additional Issues: • The Virgin Media website and app often fail to load, meaning I can’t manage my account or track the complaint properly • Some sites won’t even load until I refresh several times, High ping, Buffering and Low Quality Streaming • I’ve seen others on this forum and elsewhere with similar unresolved latency and routing issues I am in the process of escalating to the Communication Ombudsman since VM want to issue an unnecessary and long 28 day wait for a deadlock letter and the issue is obviously unresolved and at a deadlock with managers contradicting each other. I just want my normal internet service back.High latency errors on my network (Superhub in modem mode) - Logs attached
I have my Superhub in Modem mode and have a UniFi setup at home. Speed 1Gb up / 100Mb down. Getting an error every night: "Primary internet is experiencing high latency. Please restart the modem or contact the ISP if this persists." Anyone see any issues in the logs?

Hi everyone, hoping someone maybe able to help or can give some tips. I have a hub 3.0 in modem only mode with an ASUS router for my home network - has generally worked well for the last couple of years but over the last month or so have been suffering from freezes during Teams calls and occasionally a complete drop with the hub phone light blinking red and the hub requiring a reboot to restore a connection (local network through the ASUS router remains fine) I have setup BQM and copied logs from the virgin hub/modem which are both shown below. It appears to show lots of errors but not sure if these are 'normal' or whether there is anything I need to do / should be worried about?

Ethernet port dead
Recently I have been getting constant packet loss and very high latency while gaming on PS5 over WiFi. It has been going on for a week straight now. I have tried restarting my router and my console to no avail. It may be unrelated, but the ethernet port in the wall by my PS5 no longer provides any connection. Looking for any advice or suggestions. My router logs are below.Really High latency when gaming
I recently just a a hub 5 installed as I had a hub 3 before as I’ve had speeds dropping but also really high latency and lag when gaming, I’m still having the issue with the new hub and I use a cat 8 Ethernet cable which is brand new and a new console, gaming is just unplayable and been going on for months now. I have a WiFi pod but doesn’t make a difference and not sure what to now.Terrible Packet loss and Ping Spikes
This is becoming an issue more often than having no issues at all now and is an absolute disgrace! My connection for simple websites and streaming seems to just about work but whenever I talk in Discord (for both work and pleasure) my ping spikes and I have incredibly bad latency. Just take a look at how shocking this is. I have been on the phone with Customer service (which i could barely hear thanks to the terrible mic and background chatter) who told me that they know theres and issue and it will be looked into Monday morning. They continue to raise the price for less than sub par services and I am getting very tired of it. Maybe its time to make the switch now that fibre is being installed in my area.Latency and Packet Loss Spikes for Months, Are These Power Levels Normal?
Hey everyone, for the last few months we have been having very high packet loss and latency spikes (ranging from only a few seconds to a few hours at a time). For a quick example here is the connection today to OpenDNS. With average latency of around 900ms during the window (the graph is for 3 hours). Before and after will be okay with latency of between 10 and 21ms. Local traffic is completely fine. The box is a SuperHub 3 and has been running in Modem Mode for years. I have been trying everything and speaking to Virgin Media but as the issue is intermittent they are not interested in investigating. One final thought I have is that it might be related to power levels. I don't really know anything but I feel the T3 timeouts look a bit high. What do people think? This was also during a period of the connection working, will try and capture it during a spike next time. Also, thank you so much for any time you spent on this. It has been driving me insane.
