Mac Mini on ethernet sharing airport wireless for Iphone & Ipod touch

Hi everyone, I have my Mac Mini connected via the Ethernet port but I am sharing the airport out so my Iphone and Ipod touch can connect to the Internet via the wifi. I can see the wireless network but when I type the password in I get the message "Unable to Join the network "name here"", I have it set for the Channel as automatic, the enable encription using WEP, 40 bit and a five character password. did I miss something?

Try turning off Encryption and see if you can connect. If you can connect on an open network - then it is a WEP issue.

Note running Ad Hoc only allows WEP but it isn't very secure(128 bit WEP can be cracked in minutes, 40 bit WEP even faster). I highly recommend getting a dedicated wireless router so you can run WPA or WPA2.
