I have just installed a new wireless router (D-Link DIR 655) in my home, replacing a Linksys unit. I have a desktop and a laptop that run Windows Vista, and a 5 year old Apple PowerBook G4. My printer is a wireless Brother MFC-255. Since installing the new router, the two computers that run Vista, show the printer status "off line", and will not print. I have uninstalled, then reinstalled the printer software, but the status still shows off line. My Apple laptop will still print however. I'm not the most computer savvy person in the world, so any help would be appreciated, before I have a computer bonfire in my back yard.
