The messages do not look good, but as VM do not publish what they mean no normal users will not be able to help. 

Check with Area faults on 0800 561 0061 If you have a VM landline 150 this goes down to post code level. You could also try the web page status, but this is not recommended as it only covers issues that affect a very large number of customers.

VM will not dispatch any technicians while an area fault exists.

If no area faults found:

The primary place to report faults or for service requests is Customer Services on 0345 454 1111/150 if you have a VM landline or wait two or three days for a VM staff member to get to your post.

What’s not good about it I have internet I know some off errors when virgin was doing some work one more worried about is pre RS and post RS errors on channel 1

[Tudor]

Those errors are ‘small fry’ and if they do not increase it’s not a problem.

Hey Kelly1997,

Welcome back to the community and thanks for taking the time to post here on the forums.
I’m sorry to hear of the issues that you’ve been having with your connection, I have looked into your connection from here and cannot see anything that would be causing the issues with your individual connection and in your area. How has your broadband been running since you last posted?

Kind Regards,

Steven_L

Yeah all good now thank you engineer been out and sorted the issues
