I'm not sure if others have experienced this, but I find that almost daily my two Replay TVs get "unnetworked".
I've gone completely wireless (use one Linksys WRT54G with Sveasoft as one ethernet bridge and a Buffalo Wireless G ethernet converter as the other bridge, use a Linksys WRT-54GS as the router). Although each ReplayTV usually still shows the channel guide of the other, when you try to access a show on the other Replay, they aren't talking. Usually requires a few DHCP renew/refreshes and/or contact ReplayTV before I can get them both to see each other on the network. Once they see each other, no problem in streaming shows between the two.
Anyone have any suggestions as to how to maintain connectivity between the two?
