My L7650 isn't recognized on my network. I have found that the "link" lights by the ethernet port are not on (green or yellow lights). My printer works just fine via the USB port. I have followed HP online auto support but I can't solve the problem. Nobody addresses that "light" problem. I can power up the printer and watch both lights come on for a few seconds, then go out. I plug in my network cable and still nothing. This is frustrating. This printer isn't even 9 months old and I still can't get an help from HP support. Can anyone help me?
