I recently switched ISPs. The old ISP required that their modem also act as the router for my network. My new ISP did not, so I am (preferably, I might add) using my Airport Extreme (latest model with updated firmware) as my router. After doing this, I can no longer print to my DCP-8065DN. The printer is connected via Cat5 to a switch/hub that is connected to the Airport via Cat5. I am trying to print from my MacBook Air, connected wirelessly. I can delete/add the printer, but when I try to print, the print status app says "The printer is not responding." Is there some setting I'm missing for the Extreme that might be preventing it from properly assigning an IP to the printer, or something else? Thanks..
