A previous employer had a Xerox Workcentre 7655 which they changed the following year. I am now working with a Brother MFC-J6710DW which also has a wireless connection and I am getting interference from the drivers for the Xerox. I "removed device" for the Xerox several times and it kept popping back up. After rebooting, it is off the "divices and printers" list but still shows up on the list of ports and I am still not able to connect with the Brother. I have called Xerox and been told they are unable to help uninstall unless I have the serial number for the printer - which can only be gotten from the machine physically or if I am connected to it wireless.
