My server & 2 rios are all connected via ethernet wire.
I have the receivers connected to a 10mb dlink hub which is the n connected to a Linksys wireless router.

I had two reos synched for sevearal hours yesterday with no issues. I did start screwing around with the queue on the master unit which ultimately caused an exception error on the server, but that was minor compared to the problems of using the beta '02' java.
