How to use airport express as wifi extender?
I have a gateway wifi router from AT&T and I want to extend the wifi range but having problem configuring it. First when I plugged the airport express my Mac's airport utility cannot locate it. Then I decide to hard wire it and my Mac recognized it but it asked for my password when this is my first setup. After resetting airport I managed to bypass the password but now it seems to be picking up another network near by. After changing it to my provider the light on my airport is still blinking and whenever I click on the airport icon on the airport utility it will indicate that the wifi network I have chosen cannot be found and that I should make sure that my main router is plugged. So does anyone who uses AT&T's gateway router has any success in connecting with the express as an extender?
