I'm using an Apple AirPort wireless network and cannot get Computer to Computer (Adhoc mode) to work. What should I do?

• To work in Computer to Computer (Adhoc mode -- WEP disabled), do the following:
  
  1. Change the channel on the PowerBook/iBook to a channel number that is five channels apart from an existing channel in the Create Network section of the AirPort Admin Utility.
  2. Create a network name in the Create Network section of the AirPort Admin Utility.
  3. Reboot the print server.
  4. Launch WP-Admin. (For OS X users, download the current OS X version of WP-Admin from the Epson web site).
