Airport Express and BT Hub 4
My new Airport Express dos not seem to playing nice with my WIFI network.
I have configured the Airport Express and joined it to my WIFI network using the Airport Utility.
It worked well for a few minutes. Then the internet stopped working via WIFI. (internet works fine over ethernet).
I then switched off the Airport Express and switched it back on again. Now none of my devices can see the Airport Express even though it is on and the green light is on. The Airport Utility doesn't even see the Airport Express.
Does this have anything to do with the security settings on my router? My router is a BT Business Hub 4.
See below for the security choices my router is giving me:
MacBook Pro (15-inch Mid 2010), OS X Mountain Lion (10.8.2)
