Consistent Disconnections

Every day or two pretty much my internet goes down.

The logs on the router show this: How do I fix this?

Re: Consistent Disconnections

Go into your hub again and post the up/down stream stats.

Re: Consistent Disconnections

Your logs in your first post are clearly showing the connection dropping between the Hub and VM's servers, it does look like an upstream problem, with the accompanying T3 errors.

You will need to contact VM for resolution, either by waiting here about a week until a VM Forum Team Member picks up the thread, or give them a call on 150 from a VM line or 0345 454 1111 for a quicker response.

Your power levels and downstream SNR are fine BTW.

Re: Consistent Disconnections

great - I will in the first case try and wait for them to look here (as I have all the logs already!).

Thanks for your help!

Re: Consistent Disconnections

Hey dylanuk1,

Thanks for getting in touch and Welcome to the Community! 😄 

I'm sorry to hear you've been having trouble with your Broadband connection recently. 

I've taken a look at your account and can see that we have an open SNR fault ticket in your area (Ref:F006230406) and the review date is currently set for 5pm today.

Let us know if you're still having trouble this evening and we can take another look. 

Take care 

Rebecca

Re: Consistent Disconnections

Hi Rebecca_G

I was away and then there were some more service issues with our connection. That has now been fixed - but I am still seeing this issue approximately once per day:

Is there something you can do about this?
