Question

We are experiencing random connection drops during the day, here are the modem stats, for you to hopefully spot something, all connections are tight!

It's unusual to have 'Post RS Errors'.Maybe a bad Hub.

Tudor · Answer

Those stats usually indicate noise ingress, but not always. You definitely need a technician’s visits to rectify..

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. This board is not a fault reporting system.

Any update regarding this issue?&nbsp;

Hey MacmillaN, thank you for reaching back out and I am sorry to hear you are having some connection issues.
I have taken a look and I can see you levels are very good.
How has the connection been over the weekend?

MacmillaN · Answer

Good Evening @Matthew_MLas mentioned previously in the comments, other users are saying it’s&nbsp;unusual to have 'Post RS Errors'. Possibly a bad hub and those stats usually indicate noise ingress, my hub was before posting the stats experiencing random connection drops!Thanks for your time!
