Ad-Hoc Mode allows for a connection between two wireless (WiFi) devices without the use of an access point or wireless router. 
Example of Ad-Hoc Mode topology 

Possible reasons for using Ad-Hoc mode include:

• Neither computer or printer are in close enough proximity to a wireless access point.
• You are experiencing intermittent communication issues with your wireless router caused by interference or distance. 
• You do not own a router (access point). 

• Make sure the printer is turned  ON, and that the WiFi connection light on the printer is  ON.
  NOTE:  The WiFi connection light will go ON after scanning for local WiFi devices is complete.
   
  


• Verify the connection of the temporary wireless configuration cable* between printer and computer.
  NOTE:  Close the last Windows Plug-N-Play  balloon that appears, and cancel out of the Found New Hardware wizard.
    


• View or print the printer's default WiFi settings.  Click here for instructions.
  NOTE: The SSID, BSS and Channel values are the most important.
