No ranging response received

[Jess2020]

Hi

About a month ago I noticed certain sites were having major issues loading content, other sites were fine, but some were just taking forever to load certain aspects of the site. This was on a Saturday, it lasted all of the Sunday then seemed to resolve on the Monday. This has now happened another 4 or 5 times since.

it is pretty unusable on some websites (Sky Bet and Coral are the worst, but they are not just limited to betting sites lol) but the weird thing is it only seems to be certain aspects of the websites, and not the whole site.

I've pretty much coped with it up until now but now it has started to affect me while I am logged onto my works network, yesterday and today I have been pretty much unable to do any work. I know it's a Virgin network issue as I created a hotpot from my phone network and everything worked perfectly fine, and it isn't just limited to my computer as it does it on every single device, either via wifi or connected direct to ethernet. I have the router in Modem mode and use the Google nest network but I also know this isn't the issue as I removed that completely and went back to basics and it still does it.

I haven't been able to put my finger on it but I googled and found some info similar to mine. I have logged onto the Hub and it seems I keep getting this particular log:

No Ranging Response received - T3 time-out;CM-MAC=**:**:**:**:**:**;CMTS-MAC=**:**:**:**:**:**;CM-QOS=1.1;CM-VER=3.0;

It seems to last a whole day/evening. It's currently not working again (it was working no problem at 5, but suddenly started to go haywire again by 6.30).

It's getting quite infuriating now to be honest. The service status I have ran said there are no issues.

I have tried everything, including keeping my router off for a whole day but it still just keeps happening.

Any ideas?

Thanks

Update: it is still the same this morning, so infuriating!

You need to power your power levels, Pre and PostRS errors and Network log for comment.

Also setup a BQM here  www.thinkbroadband.com/ping  This will monitor your VM circuit 24 x 7 and help diagnose any issues.

All the info I could find is below. It's still not working even though I had the router off for 2 hours.
