I recently installed a new Frontier Wi-Fi router and the person who installed it suggested a 5 GHz setting alongside the 2.4 GHz, which is quite nice. However, only certain devices can find/see the 5 GHz channel in the Wi-Fi settings (the default is 2.4 GHz, called Frontier111 for example, and the 5 GHz is called Frontier111_5G).
All Apple devices and the TV (Samsung) can see the 5 GHz Wi-Fi AP, but the Android phones and one Windows 8 computer can't. One Windows 8.1 can find it strangely enough.
I've tried changing settings in Device Manager but it doesn't help much, only buffs the 2.4 channel performance by a bit. Also, there are no settings that show 2.4 or 5 GHz in Device Manager under my Wi-Fi driver. What should I do to fix it?
