Last night I powered my Xfinity Surf Board SVG2482AC off and then back on. Since then, my Honeywell wifi thermostat will not connect (all other wifi devices have connected). I get the following error: "The thermostat was unable to obtain an IP address from your network. Make sure that your network is configured to assign an IP address to this thermostat." I've never had this problem before, and the Surf Board instructions say nothing about configuring the router in such a manner. Any and all help appreciated!
