Im trying to add my Airport Express to my exisiting wireless network - which runs from a speedtouch base station. I only want to use the AP to use air tunes but i cant seem to get it running in client mode. The interface on the Airport Utility seems different to that described in the online help here: http://support.apple.com/kb/HT1731
Everytimes i try to add it to an exisint network the AP dissapears on its restart. Any ideas if what im trying to do is possible. I've tried creating the network initially with the ethenet cable connected - which works, but then when its detatched although the AP status light stays green it disapears from from the network and i cant stream.
thanks for any help and advice.
This was the post that finally got my airport express working! Thank you! I was doing everything right except choosing the correct security protocol. I had to call my ISP to have it switched from something I hadn't even heard of to WPA/WP2 then BAM, it worked first time. Apple should really have included something about the security settings in the manual...that would've been helpful.
