First thanks for any help I get. Now here is my dilemna. I'm using Air Port extreme, connected to a G5 with my Powerbook laptop connected to The G5 wirelessly. All working fine and have been for a year. Just updated to Leopard(everything is up to date) ran Time Machine with my Seagate 750GB external HD(connected to G5) as the the backup and it works fine. But when I try to find Time Machine with my Mac Powerbook through my wireless network, I can't find the Seagate external HD drive. Please help and thanks for reading!
