My BluRay DVD player will connect to the first node that it sees when the mesh comes up (router node), and stick with that connection. The router node is all the way across the house from the player. Kinda marginal, but it doesn't roam, which I suppose makes sense for a stationary DVD player *smile*. So I've bound it to the node in the room that it's in, and that makes things work better...at least the sense of order appeals to me, makes it do what I think that it should do on it's own *smile*.
Works perfectly for us, by the way, sticks to the node in the room that it's in like glue.
