VM don't do traffic management anymore and haven't done for quite some time:
"We've got great news for all customers on our broadband tiers of 30Mb and above. After listening to your feedback, we've decided to stop applying our traffic management policy to download speeds. So now you can download as much as you like without worrying about traffic management slowing you down.
Our new policy is simple:
We only restrict upload speed
Your speed is only reduced while the upload threshold is exceeded. So the speed reduction could only last as little as an hour as long as you reduce your uploads"
Edit: I just realised which thread this is. Without going round in circles about traffic management and anything else you can think of can you copy and paste your power levels, config and log from the shub so we can take a look at what is going on. Click this
link and scroll down to the fifth post (mine) so you can see what you are looking for. If you are using the shub in router mode (which I am sure you will be) go to
http://192.168.0.1 (you can click that) it will take you to the router login page which is the first pic on that link I gave you.
