This sounds very familiar. I am on 200.7.10.102.64. I will try to downgrade and see where it gets me.
Regarding Syamantak's mentions - this sticks out:
"If both APs are installed within proper distance where mesh AP can reach root AP, then roaming between them will also seamless."
The mesh is alive and well (or so the image leads me to believe)... but roaming is far from seamless. Though, I notice it has nothing for the signal column which leads me to believe it is backhauling via the wired LAN. Is there a way to switch the mesh to use wireless only to see what I get?
