I just set up a network of 315s and have connected several devices to it without problems. But I am now trying to connect an Apple Airport Express, configured as a bridge, so I can stream music through it. I can identify the AirPort and configure it to try to join the network. But it never joins, and I just get an unknown error message. They are both WPA2 passwork protected, and I even tried creating a new Aruba guest network with no password to see if I can get the Airport to connect to it. No dice. Has anyone been able to connect an AirPort Express to an Aruba network, and are there any tricks or settings you can recommend? Thanks
