You need to un-install the printer, again, using the patch.
Restart your computer.
Attach the 3300 with a usb cable to your computer. Insert the 3300 setup disk or use this 3300 Utility. It will ask you for your SSID, type of security and password for your wireless network. Now remember to install the latest firmware for the 3300 wireless adapter. Attach your printer to the 3300 with the usb cable.
Install the proper drivers, choose network, choose I am using a wireless print server and follow the instructions.
Do NOT join the ink program as it causes a problem in Vista machines. Your ink levels should also match the printer.
