I can't get my Photosmart 7510 to connect to my wireless. The troubleshooter says to turn off the MAC address filtering. It IS off. My Actiontec PK5000 has an area int the settings where a MAC address or IP address can be manually entered, but I don't know where to find these numbers.
My old 3-in-1 had this same problem, but I gave up and just used a USB cable and the Bluetooth connection with my laptop.
