My router (AirPort Extreme White gumdrop style) is only 2.4 ghz. I was just wondering if there is a way to know what another hotspot is running at so I can test my devices on both frequencies to verify proper functioning.
I don't know if you can without logging into the router. There might be an app out there but I haven't heard of one. The only way I knew it was the 2.4ghz antenna was because it wasn't working on both of my routers. You could try borrowing a router from a friend to test it out.
