Only iMac can connect to WIFI, not iPhone, not Nexus 4 or PS3
Hello, i bought a brand new Airport Express and when I installed it I needed to put a "WPA/WPA2 Personal" security (instead of the "WPA2 Personal") for it to be detected by my phones and my PS3.
It all stopped working for no reason now. I am connected via WIFI with 1 iMac and 1 Macbook Pro but i either can't see the signal with my phones and PS3 or i just can't get connected to the internet when I see the signal (stays at "registered")
I changed my airport because of a similar problem but in the end it was the antenna that was broken (6 years old Airport Extreme). Why is it always happening and there was no change in the configuration or any update at all.
