I just got the E3200 extender because we are too far away from the router and it gives us slow speeds. I connected the router to the wall with the coaxial cable that it provided and then connected the extender to the wall upstairs with the other coaxial cable. I finally got the light on the extender to be a solid white, but I still can't connect to the extender at all in my wifi settings? What am I doing wrong? I assume the extender successfully connnected to the router downstairs because its solid white and when I unplug the cable it turns yellow, so how come it doesn't the show option to connect to it on any of my devices?
