I get the very slow speeds on all of my devices when not connected via Nord, the company VPN doesn't seem to affect this too much although it is a little slower, around 10%
I've just set two different PC's, both wired to the router to use Open DNS, my company pc sets a specific DNS when I connect to the company VPN. No difference to the speeds on either pc to note. If on my gaming pc I connect to Nord I get 255 Mbps down currently, better but not even close to what I'm paying for.
I've also tried a laptop connected via 5 Ghz Wifi, speed is 5 Mbps down 50 up, on Nord, 67 down, 45 up so something is clearly amiss with my connection.
No-one so far has been able to help me why this is happening and why the speeds have tanked without a VPN, I can only there assume throttling based on my very limited knowledge.
This has been going on since mid January this year when I upgraded, I've spoken to Virgin yet again, gone through the testing and finally they have agreed to replace the router but I'm not at all confident it will fix the issue, time will tell I guess.
Again I very much appreciate all help & advice given...
