I just purchased a new iMac running Lion 10.7.3 ( 2.7 GHz with i5 ) and a 16 Gig Wifi iPad, I also have a G4 867 Power PC running Tiger 10.4.11. Currently I have a Linksys 2.4 Ghz 802.11g router connected to a cable modem and my G4. This makes up my small WiFI network. It runs well, but I also know that 802.11g and the 2.4GHz are older standards. I have been looking at getting the Airport Extreme, but I am not sure if I will be able to set it up because the system requirements for the Extreme 10.5.7 for set up and admin. I was wondering if I could do the set up on my iMac and then unplug and plug it into the G4 ? or perhaps you fine folks could offer up a better solution.
P.S The G4 does not have a Network card or any Wifi capability, I would like to keep it connected to the network with an ethernet cable, but I am not sure if a WiFi card or USB adapter would be cost effective. But I am open to any ideas.
