Re: SuperHub 4 Power Levels

Power levels on the downstream are fine, what is worrying the Pre & Post RS errors are very high. These figures are accumulative since the hub was last power cycled. Also needed are the upstream levels, sometimes they are more important and the network log. So please power cycle your hub and post a new full set of data after about 2 hours minimum.

Re: SuperHub 4 Power Levels

Check with Area faults on  www.virginmedia.com/servicechecker or 0800 561 0061 If you have a VM landline 150

If no faults found:

Call Customer Services on 0345 454 1111/150 if you have a VM landline or wait a day or two for a VM staff member to get to your post.

Re: SuperHub 4 Power Levels

Channel 11 is really bad with noise ingress, the frequency that it is on is right in the DAB spectrum band, so that almost certainly where the problem lies. Check all cables connections are tight. You probably need a technicians visit. Best to wait for a VM staff member to get to your post.
