My ImageClass MF264dw was working fine until this morning, when I get the error message "Printer is not connected" on my computer. I've re-connected to the wireless network from the printer. When I re-enter the password for the wi-fi, the error light flashes for a second, and then the screen says "Connected." I've tried restarting the computer, the printer, and the wireless router, all to no avail. Any help would be appreciated.
