VM Network team help needed in London area - total loss of internet - T3 T4 critical errors

Tuning in

I am posting it for the 3rd time, as for some reason the posts were flagged as spam. I will try to post the stats in the reply.

About three months ago we ordered 1GB package. It worked fine for a few weeks and then for a couple of months, we had all the problems with the broadband. The internet keeps dropping intermittently or sometimes it just does not work for days. It had not happened to us for more than 5 years. We both work from home and are heavy internet users. The contract is in my partner's name. We live in London.

We had probably 5 technicians coming over after countless of fruitless customer service calls. They are changing the Hub5 router (which does not really make sense, but they probably need to do something to justify their time on the premise). It only helped once when a more experienced engineer, Steve, came in and contacted the Network directly. A couple of days later everything started working again.

And the router was in "modem mode" (I have an external Asus RT-AX82U (fw: router linked via Ethernet cable - 2.5GB slot). I was advised not to do it (which is strange as it had worked for 2 years on HUB3 without any issue), so since the last change of the router it has been running as per default, but I still have an external router connected as an extension for the range.

What is really annoying is when you want to report that something is not working and you go to VM Status then you will get this lovely message:

"We can’t see any issues affecting"

Then you click that there is still an issue and you are getting:
"Looks like there’s still an issue with your connection
We’re looking into it. Check back here after 0 hour and if there’s still an issue we’ll help you book a technician." (I have just spotted it is 0 hours.. and I cannot do anything like I am blocked on your system - probably with a label - "difficult customer, do not let them book another tech visit")

Anyway, here are the stats. Hopefully, somebody from VM will spot something and will send help. And I am really hoping this is not my external router settings (which I really do not think so).

Hi @upsetgamer,

Thanks for coming back to us about your ongoing connection issues. I've taken a look at our systems and I can see that your downstream power levels are not where we'd want them to be.

In order to have this looked into and arrange for a technician appointment, I'd need you to confirm some further information.

I'll send you a Private Message to confirm a few details, so please keep an eye out for an envelope at the top right corner of your Forum page. I'll be in touch soon.
Thank you.

I have a new router since yesterday (5th one... yay...). The initial post had data from the old one. Sorry about it. I have not had internet for so long that they managed to change it again.

Here is the latest:

Hi @upsetgamer,

Thanks for coming back to us. After looking at our systems again, I can still see some downstream power level issues that may be impacting your connection.

Please get back to me via Private Message if you'd like to arrange for a technician to look into this further. 

However, if your connection seems stable, keep us updated on this going forward. We're here to help.

Thanks! 😊

With the Hub in Router mode the VM Team can remotely review the Hub's connection status.

Hi Client62, the Hub5 has been in router mode only. I DMed VM too.


We chatted to VM and they will send a regional Network engineer in two weeks' time. I wish they offered us 4G backup dongle. As you can see peak times are breaking the network for 2-3 hours.


Tuning in

From numerous Twitter threads, it looks like there was some serious issue in the larger East Ldn area.

These were my readings from yesterday:


and this is from today (not perfect, but at least I managed to do all my work on wifi and not on O2 tethering).


We are also expecting a Business Broadband with 4G backup. Hopefully, this would work for us as we have our normal work and side businesses that require a reliable connection to the internet.


Tuning in

I may close this thread. The Network fixed the issue. Fingers crossed that it will not come back in any shape or form:



The vm router is in router mode but many items connected via Ethernet including ubiquity ap’s and sonos but nothing you wouldn’t expect 

someone is going to tell me next the circuit is being brainstormed and falling over

its was all fine and set up the same way 6 months ago and was fine then

whats happened 


this is today

i have today ordered bt fttp can’t put up with this anymore 



Here is the bqm monitor

what fun !!!
