HUB 4 1gb connection speeds of 80mb if im lucky

HI Everyone

So having an issue with many phone calls and chats and its getting no where so i'm going to post here to see if this helps or i might just downgrade again or even leave virgin media at this point the amount of effort it has cost me, anyways i digress the main issue is my DOCSYS 3.1 connection.

I have rebooted and hard rebooted countless times now and things stay the same. i haven't gone above 80 mb since the 6th aug. 

I believe my modulation should be QAM4096 but its currently QAM1024, also getting a-lot of errors on my docsys3.0 connections, here is a print out of my router status downstreams, upstreams are great.

Re: HUB 4 1gb connection speeds of 80mb if im lucky

Hello buddy.

Yes 3.1 channel should be 4096, I suspect it's dropping because the power level is too low. It's a touch noisy too at only 40 db.

3.0 channels power are on the low side but within spec, at least at the time you took the data.

The worrying thing is the post rs errors on your 3.0 downstream.

You need a bit of a tune up/levels adjusted perhaps that will eliminate the noise.

Either way it's not your equipment, it's up to virgin to fix it.
