HP Recommended
Product: HP Officejet Pro 8600 Plus e-All-in-One Printer - N911g
Operating System: Microsoft Windows 10 (64-bit)

I just installed the latest update 5.7.0 to HP Print and Scan Doctor after several months of being unable to connect my Officejet 8600 Pro to my wireless network. After the update I got to the last step of connecting successfully, then a message saying "Unable to connect . . ."  I ran a Diagnostics and everything was fine except "No Filtering FAIL." What does this mean? Is it fixable? If so, how? Could it be caused by a USB cable running from the printer to the computer? Thanks in advance for your help.
