Hello all! I just ordered a new iBook G4 for my fiancee, and being new to the Mac world, I have a few questions regarding airport. 1) Airport card: I know the iBook G4 uses AirPort Extreme, but can I put in a regular AirPort card 802.11b and have it work? Also, would the speed make any difference for web surfing and email? I have Earthlink cable modem, if that makes any difference... 2) AirPort base station: I really don't want to shell out $200 for the Apple base station (although it looks damn sexy, and works great probably). What are my options for a base station? Does it have to be 802.11g, or is b ok? 3) 2 computers online: I will be getting a PowerMac G5 soon, and I want to hook it up to the cable modem also. Do I need an airport card for the G5 as well, or can I connect the G5 with a cable to the cable modem and also have the wireless setup going for the iBook? As you can tell, I'm very new to all this, both Macs in general and wireless networks. Any help or advice would be greatly appreciated!
