Upstream channel 1 (id 6) has x170 t3 timeouts!
Thats bad even for virgin.
They could just be old so it may be worth rebooting / factory reset to see if it locks on to a different channel ID.
It's a quick simple way to see if we can get it better.
Either way, its a clear problem and it's not your fault.
If a reset doesn't help it's up to virgin.
The rest of it looks good.
