Hi Antonio,

Thanks for the reply. I will attempt these tests today and provide you as much feedback as possible.

We are using loop avoidance because in some (if not all) installations we will be doing there will be multiple AP wired to the same network to provide redundancy. And if we move to LoopAvoidance-II if I understand correctlt if should also provide bandwidth balancing correct ?
