Hi, have replaced my old Belkin router with an Asus RT-N56R router and have set it up. Our ipad, iPod and iPhone all connect to the new wireless router fine, however our PC with an Asus USB-N13 for wireless connection will not connect to the router. It worked fine on the old Belkin router and can connect via iPhone hotspot to the new router but not directly. PC error messages mention DNS which I have flushed. Thoughts on how to resolve
