intermittent connection problems, internet keeps cutting out/unstable

I'm having issues with intermittent connection dropouts on my broadband with countless T3 timeouts. In conjunction with this I'm receiving a large amount of RS errors. I spoke on the phone and phone person forced me to reset router/he did something on his side; no change. I was then assigned a network engineer to come fit a new router and that has not solved the issue, he confirmed there's no issues with power levels either. I rang up Virgin again and kept getting non-UK call centre who don't seem to understand it's not a device problem but the actual internet is down and kept making me restart/reset the router which as proved before had no issues, and even try to redirect the call to a third party gadget support.

Below is RS errors of since the last clear out, previous it was more than 100k on some of the channels (in space of a day).

Re: intermittent connection problems, internet keeps cutting out/unstable

I'd say the power range is far to wide for downstream! (-3 --> +4.5 dBmV)

VM would need a tech to investigate!

Re: intermittent connection problems, internet keeps cutting out/unstable

It's getting to the point that due to errors/corrupt signal the router will get to the point where it will automatically restart itself once it hits the threshold. This is unbelievable, how do you expect people to WFH?

Having checked this is going to need a technician visit, I will send you a Private Message to get some more details to arrange this for you.

 

Looking forward to hearing back from you.
