I am having a problem with two of my computers, one Macbook Pro and one Macbook Air, both could not establish a connection from the Airport to the Airport Express base station. Even though with the base station I can connect other devices to it, such as the iPhones and iPads. I am sure it is not the problem of the base station. Suddenly today two of my computers refuse to connect to the Airport express base station. Does anyone have any hint to fix the issues?
I have tried to restart two computers, and also use the iPhone to enter the Airport Utility application and upgrade the firmware, everything is fine excepts that two mac computers refuse to connect.
I am having headaches for a while now, thanks in advance.
