Moving the printer onto the actiontec ethernet port? if that fails you have a printer or cable issue.
We had a MI424WR Router, went bad after the elect. went off. Received a new one, went thru the steps. Our Belkin and Dynex switches would not work. Help from Verizon was: We don't support switches.
Turned everything off - unpluged eveything for 5 minutes.
Started MI424WR Router, waited 5 minutes, started computers 1 by 1, all went on line OK except our 810 Artisan Epson printer - We can't see it, locate it,
Re-installing all software for Artisan, still can't see it on any computers, Mac 10.8 and Dell W7 machine.
