Do you have a Windows notebook or computer in the house? If so, you can get it connected to the WiFi using the USB-to-Wireless set up that comes with the software for the printer. Normally you could also do this on a Mac, but this printer is not supported in OS X 10.8. It can work via AirPrint, but there is no full feature software and that software is what allows you to connect to the network this way.
Another alternative is if you have a wireless router with WPS (WiFi Protected Setup). Does your router have that feature?
Thanks,
