Hi,

Been having this intermittent issue for approximately 2 weeks now.  When i say intermittent, its everyday, at intermittent points through the day.  
To confirm:
This is on multiple devices including Android phones, android tablet, 2 laptops on both frequency bands (2.4 & 5ghz), & desktop hard wired ethernet direct to router.

All devices drop at the same time.

I have ensured connections are tight on back of router, and on connection point internally in the house.

I have power cycled the router multiple times.

I have factory reset the router.

I have setup on thinkbroadband the monitoring wherein it pings continously.  See below of results.

https://www.thinkbroadband.com/broadband/monitoring/quality/share/b019587bb9da7efa180e540cb6ff1d16b3...

Upon visiting the status within my account, where i enter postcode and surname, its had on there listed there is a broadband issue pretty much everyday.  

Logs from router:

To put it lightly, I'm tiredof this, who do i speak to / what do i do next, as both my wife & I wfh?  The support desk is frustrating, as they just blame your equipment.  I'm technical, so please do let me know if i can try something different, or whether its needing an engineer to come out?

Hi Jouma,

Thank you for reaching out to us in our community and welcome, sorry to see you have been facing an intermittent connection, I was able to locate you on our system with the detail we have for you and it does look like a short term connection issue, this is consistant with a loose connection, please can you check all your internal connections, this includes all equipment plus any splitters both powered and standard.

Regards

Paul.

[Jouma]

Hi Paul,

Thanks for the response.

I can confirm I have checked internal connections, both at the terminal at the wall, and the back of the router.  We do not use any splitters.

I can also confirm the issue is prevalent with a laptop and desktop connected to the router using an ethernet cable.

Please let me know if there is anything further I can try / provide.

[Ashleigh_C]

Hi there @Jouma 

Thank you for updating us and we are so sorry that checking the cables has not improved things. I can see there are a lot of disconnections on our side so I think it would be best for us to get an engineer out to take a look. 

I will pop you a PM across now so we can arrange this, please keep an eye out for the purple envelope in the top right corner of your screen alerting you to a new message. 
 

[Jouma]

Hi Ashleigh.

Thanks for the response, unfortunately i've not had a PM come through?

[Jouma]

Hi,

Can i nudge this please, as this is still an intermittent issue

[Ilyas_Y]

Hey @Jouma, thanks for reaching out to us on the Virgin Media forums.

I'm sorry to hear about the issues with the connection.
I've had a look and this will definitely need to be looked in to 😞
I will send a private message - watch out for the purple envelope inviting you in.

Kind regards,
Ilyas.
