Intermittent broadband
Hi, I have been a VM broadband customer for many years. I am on the M350 broadband package. Over the past week I have had frequent internet dropouts spanning multiple days. Annoyingly this is happening intermittently which makes it harder to debug. There are no known broadband issues in my area. My internet can be working fine for a good few hours but suddenly I will have no internet bandwidth on my devices and I am unable to access any web pages. When this happens the connection drops for varying periods of time ranging from a few mins to sometimes as long as an hour. When I have no internet connection there doesn't appear to be any change in the status lights on the superhub. I have the superhub 5 which I upgraded to over 4 months ago and it's been working absolutely fine until last week. The superhub is running in router mode. I connect from multiple devices over wifi and there is no difference which device im using, the problem occurs on all of them. I have tried restarting the superhub many many times. Sometimes the internet comes back when the hub reboots but often it doesn't. When the internet is working I get very fast speeds: I setup a Think Broadband broadband quality monitor a few days ago. Below you can see some graphs over the past few days... Friday had no dropped packets: Saturday had some: This morning / overnight has been terrible: I would appreciate some help to try and understand what's going on here as it's been extremely disruptive especially when im working from home. Thanks in advance328Views2likes9Comments
Hub 5 dropout
Afternoon, I recently contacted VM to discuss possibilty of obtaining a pod to assist an issue in 1 room of our house that has low wifi signal and they accepted that 1 was required, but as i refused to pay the £8 monthly charge (i don't agree with it), they then offered to upgrade my b/b to 1gig package and sent the new hub5. Since it has been about 10 days now, i am finding the Hub 5 keeps dropping signal in that my phone says connected to wifi but no internet access. Having used the VM Connect app, it does a test and says unable to connect to network but then it can connect instantly and says all is good. I have also noticed the wifi coverage is nowhere near as good as it should be in other areas of the house, rather than the 1 initial room that we had previously. In the room where the hub is, we have full strength wifi. Reading the forums now, it appears many other people have experienced similar issues with Hub5 so hopefully someone from VM can help here as the webchat option is waste of time in my experience.

Internet and TV drop out since December
I’m hoping someone from Virgin Media can help as this issue is still ongoing. My broadband and TV services have been repeatedly dropping out since the end of December. An engineer attended on Saturday (after I waited in for the appointment) and advised that there is a signal issue affecting my property and the four neighbouring houses. I was told this was a known fault and that it would be fixed right away. Unfortunately, nothing has changed and the broadband and TV are still dropping out just as before. This has now been going on for several weeks and is extremely frustrating. We have kids in the house and they are going crazy without a reliable internet connection, especially when the issue was already acknowledged as an area-wide fault. Can someone please: Confirm what the fault actually is Advise when it will be properly resolved Confirm whether this has been logged as an area/network issue Happy to provide account details via private message if needed. Thanks.75Views0likes1CommentEthernet on black WiFi pod issue
I have a hub 5x and two black WiFi pods on a 350Mb package. Off one of the WiFi pods, I have a tp-link powerline adapter connected to the pod via ethernet cable to serve internet in a garden office. All has been working fine for around 6 months. In the last week, there was some sort of over night outage for a few hours. Since then I’ve had issues with the one WiFi pod and internet via powerline (everything else came back fine after the outage). The WiFi pod pulses white indicating a connection issue back to the hub. I’ve power cycled everything in order several times. No luck. I’ve swapped round the WiFi pods in case of a specific pod fault and same behaviour. I’ve tried different Ethernet ports, Ethernet cables and power sockets. Again; no luck. What I have noticed is that the pod works/connects fine WITHOUT an Ethernet cable connected. As soon as I connect the cable, the pod cycles through connection again (blue, then green lights) but doesn’t revert to a solid white light; it pulses white as if there is no connection (even after waiting some time). the WiFi pod and hub are only six metres apart and with it working previously I’m confident it isn’t a placement issue. I can’t plug powerline directly into the hub (without a lot of cable/drilling work) as the hub is placed on a different electrical circuit to where the WiFi pod is placed. Both WiFi pods show up in the VM connect app indicating they are provisioned correctly I guess. I do have intermittent issues where VM app service status check returns that it can’t connect to hub but internet is working fine for a plethora of devices connected wirelessly and wired into the hub and the other WiFi pod so I haven’t paid much attention to that. I’ve exhausted all ideas on remedying this problem. Help gratefully received.Solved181Views0likes9CommentsPS5 suddenly stopped connecting to WiFi

I’m living in postcode B90. During these months ,the boardband service was keeping unstable. The service was keeping on and off especially on Sat, Sun or Public Holidays. It’s totally disappointed. Is that the services demand over load the server ?48Views0likes1CommentComplete loss of service - Tracking progress?
Does anyone know of a solid way to track progress on an issue? My internet has been out since Sunday afternoon, I can see in the network logs that there's an issue with the termination service, mac address isn't coming back with anything. Reported issue Monday morning, was told engineer was coming out Tuesday but that was a no show, chased this. Rescheduled on Wednesday, who popped over to say that he's seen, and checked with a outside cable engineer, looking at an issue. Had to follow up that night, because I'm still in the dark about it all, was told that there's an issue with the 'pit chamber' (hole under the junction box?), and it would be sorted by Thursday 7pm... It wasn't; Long discussion with support last night who explained the issue further, saying there was a blockage etc.. and it will be resolved in the next 72 hours... Now I don't mind, and appreciate that it can take time to sort, but there's been no real updates throughout, only a text to say an engineer is scheduled, and only when i contact support. The area service checker says everything is fine and dandy, so my wife and I have been tethered to my phone to work for the last 5 days, and I've had no messages/texts/emails since, to say what is happening. Support have been really polite and helpful, but I feel like they're slightly disjointed from what's happening on the ground? it'll be good to have an engineer give me a explanation of the issue and how it will be resolved, if there are difficulties and an ETA.
