I reuqest you to turn off the firewall program (Norton, McAfee, PC- Cellin etc) if you have installed any and then try using the printer.

dsl signal / light on modem ..ok
connection to computer ..ok
able to log-in to the internet service provider ..ok

check your IP address setting on the computer, must be set to automatically get IP address, same goes for the DNS setting.

When in Audio Tuning Wizard ask you to enable RightSound technology just say no. that solves everyting to me.
