Power levels too high

[donmaca]

Hi, so I've just moved to a new property and did a self-install. Looking at my Router stats it looks like my Downstream power levels are far too high - can someone confirm? Thanks

Downstream are way too high, 10 is the max, although you do not seem to be getting any RS errors. You need a technician’s visit to adjust them unless it’s an area fault:

Check with Area faults on  www.virginmedia.com/servicechecker or 0800 561 0061 If you have a VM landline 150 The phone goes down to post code level.

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.

Thanks, I managed to get a technician booked. There were RS errors but for some reason they disappear...

[Tudor]

Happens exactly the same on my Hub4. Probably yet another firmware bug.

Hi donmaca,

Thank you for your post and welcome to the community. 

I'm very sorry to hear about the broadband issue you've bene having. 

I'm glad to hear you've been able to get a technician booked in for this. 

Please do let us know how the visit goes.

Ive just more or less had the same issue as you with +10 to +11 and tech came out.

I was advised by the tech guy the self install cable is junk and he always replaces it with the thicker cable.

if you do manage to get a tech ask them to put in the thicker cable with the splitter and inline filter (if you don't have a wall box and only a cable from the wall).

Hi SonarUK, thanks for the message and welcome back to the forums. Can you confirm if you are having issues with the service or did the engineer indeed replace the cable when they arrived? Please let us know if you need anything ^Chris
