Upload Speed Issues Along with Signal Loss

[amel2018]

Since Saturday (1st October 2022) I have had poor upload speeds, <8Mbps on a 1gig line, the download speed is fine. Looking into this it appears as though from almost bang on 1pm which seems suspiciously round, there has been signal loss on the line (see attached thinkbroadband) then looking further into the router stats the upload channels are syncing at 32QAM on all but one of the channels which doesn't appear to be right, I'm sure these were 64 previously.

Virgin CS doesn't appear to see any faults and believe they don't guarantee uploads despite this causing an issue with certain connections. Any ideas how to progress? Have tried all the basics checking cables and resetting Virgin Hub 4.

Hi @amel2018 

There are a lot of tech guru's on the forum that can look into your issues but when posting the hub stats they need the full details from the Router Status page. So please  copy/paste 3 FULL sets of data onto here (not screenshots) – from the Downstream, Upstream, & Network Logs pages.
