The printer was set up as wireless and was working perfectly yesterday, but today, it refused to print in wireless mode. However, when I set it up as USB, it works fine.\n\nWhat I've tried:\n1. Updated firmware\n2. Reset Printer \n3. Reset Network\n4. Unplugged printer and held down restart button, then plugged back in\n\nSo far, nothing has worked.\n\nWhen I tried to set the printer up as wireless, it got to the point of asking me to unplug the USB cable. But, when I unplugged the cable, Next would never light up so the wireless installation could finish. \n\nI'm flummoxed and don't know what to do next.
