I've got the same issue with the receivers changing IP addresses every time I need to reboot the server. (The negative is that the rio named basement before reboot is now actually main level and I need to change names in the trio web app.) I have a 2wire router, but as far as I can tell no reservation process/procedure exists. Would it be technicallyhard to use the MAC address to link to the player name, it would seem to fix the problem if the router can't handle mapping the MAC to an IP address? My current workaround is not to reboot the server, but with all the windows critical updates that are coming out, thats only good for a week or so at best.
