when using Route Policy to restrict my ADSL for Business and my Virgin Media connection from Home Use,

On this new firmware, or you mean you had the difficulty all along ?

It's never worked . The new firmware enable syncing with annex m, but load balancing was still rubbish.

In fact I now have an RMA to return this device, so hopefully it will get fixed once and for all.

Back to my trusty Billion as this router is rock solid, even without being able to load balance.
