Upstream/Downstream Channels DB

Hi all,

Suffering with some latency spikes, please could someone have a look at my Downstream/Upsteam channels - also if someone could explain it, that would be even better

 

Thanks!

Re: Upstream/Downstream Channels DB

Power levels are way too high on downstream, nearly double the maximum. Probably need a technician’s visit 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 http://www.virginmedia.com/servicechecker

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.
