The main router is set for g only as this was the suggestion on the Philips web site. All software is up-to-date.

The access point in Room 2 is on DHCP. It's actually a router that I'm using as an AP. I'm not sure if I can set that as a fixed ip. I'll have to play around with it.

Other than that, however, all the regular devices on the network are fixed ip as I indicated in my first post. From time to time, however, I do plug a laptop into that pronto network and that is also DHCP. Since I use that laptop to plug into another sub net on my LAN as well as the pronto subnet it would be a bit more complicated to set it on fixed ip.

BTW I am also controlling a pre-pro and a video processor via RS232 ports on the RFX9600. I assumed that this would not have anything to do with the problem.
