Just got a 15" G4 Powerbook and Airport Extreme base station. I have the base station connected to my DSL router via the WAN port on the base station. My iMac G5 is connected to base station via the LAN port. The iMac does not have a wireless card. Powerbook works great with wireless Internet connection. Imac connects to Internet also just fine. But, I can no longer print from my iMac to my laser printer which is part of my LAN by virtue of being connected to one of the ports on the router. Can't print from the Powerbook either. Neither computer can see the laser printer. When I try to print, I get a "Printer not responding" error. What am I doing wrong?
