Where you connected with the usb cable ? I do know that on the install cd it has the option to just connect by wireless or by usb.
Now on the back of the printer there is the network cards address it's called the mac address , you can write that down and then go into the router and in the tab where you have the accepted devices and you can see the mac address of the computers that are connected to the router you need to make sure that the mac address of the printer ie in there , if it isn't you can add it or I should say you need to add it. Then run the installer again.
If that doesn't work then go into your computers , control panel / network and internet / homegroup / view and print your homegroup password and write down the homegroup password. This is what the printer needs to connect to the router and you may have to manually enter it into the printer. The little screen on the front of the printer has an option to connect to the router and you will be prompted to enter in the router password.
