My Move 2 appears to be a very sticky client when it comes to roaming between the accesspoints throughout my house. I have also have two Roams that do not have any roaming issues and hop from one to another AP without issues. I guess some driver-tweaking is still required to improve that.
Another issue I encounter is that the Move 2 refuses to connect to one of my accesspoints that runs on 5GHz wifi channel 153. It simply does not connect to it, even when it is placed next to the AP. Are there any region restrictions in play? I am in Europe but run my wifi system with US location setting. None of my other wifi-clients (Androids, iPhones, etc.) exhibit the same problem.
