I was hoping to get some help / suggestions on the setup of the 9600 and the rfx9400 and a fp-1 for a customer of mine. Here's the scenario :

9600 AND THE RFX WORK PERFECTLY IN STANDALONE MODE. I ADDED THE FP-1 ( HARDWIRED TO HIS ROUTER AND WORKING FINE) AND THEN CONFIGURED THE 9400 INTO NETWORK MODE AS WELL AS THE PRONTO. CONFIGURED THE PRONTO TO THE ESCIENT. HERES WHERE THE PROBLEMS START. NOW THE PRONTO READS "CONNECTING" IN THE TOP RIGHT CORNER AND WHEN I PRESS AN ICON I GET "COMMAND FAILED ". WHEN I SET THE RFX AND PRONTO BACK TO STANDALONE, EVERYTHING IS FINE AGAIN.

After reading through all the posts concerning 9400/escients, I realized I hadn't updated the firmware when comfiguring the 9400. Would this be it, or do I need to do more setup on the customers Router to make this work? Any help would be greatly appreciated.

I would definitley start with updating that frimware and then get back to us

It sounds like you are not connecting to his network, therefore none of your commands will work in network mode. You need to make sure that the 9600 is set correctly to access the wireless access point on the home network. Then you will be able to send commands through the 9400 and communicatre with the FP1. The 9400 will not serve as your access point for the home network, it only lives as a wired component on the network when used in network mode. Hope this helps and let us know if you get it resolved.

I think I would check that the physical connection from the 9400 to the home network is reachable by the home network's wireless access point (so there's a path: 9600 -> wireless access -> wired access -> 9400). It's a long shot, but if your customer has done something funny with subnets on their switch/router, it's possible everything's connected but still won't communicate.

I would also connect a PC to the home network and do a "ping" to the 9600 and 9400 from the PC. If you get a ping reply from one, you would most likely get it from the other (unless there's some very funky networking going on that you probably wouldn't find in anyone's home). If you don't get ping replies from both, then there's a chance the customer's home network is your problem. If you do get ping replies from both then I would suspect a pronto-side configuration problem. I have multple 9600's and 9400's on my home network (all in network mode) and I can ping all of them from my PC.

You could also take a look at the diagnostics screen and see if that gives you any more info (Backlight+Menu+FirmKey2)

I don't know if this will help, but it might give you a couple more ideas.
