Archer C5 AC12000 Version 1.2   Have a Honeywell RTH6500 thermostat that I can't do the wifi connection procedure.  I connect to the thermostat, but then when I try to connect to the router it says no internet connection and blank page.  I've tried differernt phone and tablet settings manually tried 192.168.0.1, nothing worked, do I need to get into the router page and do some configuring?  Thanks
