Downstream power levels high again

[rolandjp]

I've taken notice that my downstream power levels are high since my last virgin media engineer visit (about a year ago) but never questioned if its a problem but will now. I read somewhere that it should below 10 and upstream power over 34. Would I need an engineer visit again?

Way too high. Either need adjusting at the street cabinet of a 10dbm forward path attenuator fitting, both are a technician’s job. Best wait for a VM staff member to get to your post.

Downstream power should be between -6 and +10, Upstream power between 34 and 51.  QAM on Upstream should all be 64.  That's what I go by anyway.  It's a decent yardstick for most circuits.

Hmm thought so, will wait for a staff member.

Hi rolandjp,

Thank you for your post. I'm very sorry to hear about the issues you've had with your broadband issue. 

As it has been some days since your last post, I just wanted to check in about your service. 

Are you still having issues?

[rolandjp]

Not having issues but as other members said power levels are not ideal and needs adjusting. Is an engineer needed?

Setup a BQM the hub can tolerate high dBmV downstream

I be more worried about your upstream
