We have a Ruckus network running on a Zone Director 3000 (9.12.2 build 101 fw), we are running entirely on R710 Access Points.
We are finding that the handful of surface 3 devices we have on Campus are unable to remain connected to an AP. They connect and then about a quarter of a second later they renegotiate on to a different AP, the ZD logs show the constant hoping. It happens so much the devices can not move much traffic.
The driver Microsoft ships doesnt have roaming controls or they aren't exposed in the gui. I've played with driver settings that are in the registry and not exposed by the gui, and none of it has made the connection any more stable
