Slow upload speed on Gig1

I posted this earlier on the wrong account so here goes again...

I am seeing reduced upload speeds of around 15-25Mb all the time. 25Mb is rare, it is normally closer to 15Mb.

I have spoken to second line support, after waiting 1.5 hours and being transferred to 3 different people, to be told basically Virgin don't care about what upload speed you are getting it's not guaranteed and that there is no problem on my line.

Thing is, I have been told all upstream channels should be 64QAM, I have 1-2 channels at a time that are dropping down to 32QAM. Although second line support told me this is expected behaviour.... It was not like this when first installed so I find it hard to believe this is expected.

I have reset, tried different cables, devices, ensured the coax cables are connected correctly, tried with and without the attenuator fitted by an engineer for my old Hub 3. Still the same issues.

Live BQM 

My BQM looks awful, it has actually generally been ok (see below for snapshot from 11.01.21)

11.01.21 BQM 

SamKnows real speed test shows around 21Mb upload hitting the router right now. Download is fine, I am testing on a wired gigabit enabled connection.

Please, could someone confirm if there is a problem here or not, phone support don't seem to be all that helpful.

I will post router info below.

Thanks
