Millions of Pre-RS errors

[NChannon]

For a while now I've had "funny" net issues but it's been hard to diagnose because some connections seem to be fine, but after reading a few forums posts I noticed that my hub stats aren't great...

My set-up is SH3 in modem mode. Router Status logs below are at the end of this message but the short version is I think the downstream power levels are too high, the SNR is too low and we're getting hundreds of millions of Pre-RS errors (quite literally, uptime of 24 hours can be into 500,000,000 errors) and although Post-RS errors are zero,  Ithink this is hindering the hub's performance somewhat because we just have strange net activity.

One thing that's really strange is that for the life of me I am unable to get in contact with anybody about this - I hate the UK telecoms industry for support, they've just got it all wrong, absolutely horrendous.

I'm hoping for someone from @virgin to help/arrange a tech visit to get this sorted as I rely upon it for work and I'm worried it's about to die completely.

Logs (No network log as it's pretty empty) - I think upstream looks OK?
