A:Answer All AC Airless is either 2.4 GHz or 5.0 GHz, did you mean it is not recognizing your 5.0 GHz? You have to make sure your 5.0 GHz has a SSID, and a Name, otherwise it cannot log on to it. I know mine at home has two separate names, and two separate passcodes. Did you name your 5.0 GHz wireless yet?
