I just purchased a MBP 15" which has an 802.11n Airport Extreme built in. I also purchased a new Airport base station which has 802.11n. I have a desktop G5 Power Mac, dual 1ghz which I bought new in 2004. I would like to upgrade the Airport Extreme inside the G5 to make it compatible with the 802.11n Base Station, but it seems that the only Airport Extreme available is 802.11g. I think I have 802.11b in the G5. I also have a 12" powerbook also purchased in 2004, which my wife will use for email and web browsing. What is the best way to configure all these to get the best wireless reception. I also want to put a remote hard drive on the base station to use with these three computers in the house. I am wondering why there is no n version of the extreme that I can put in the G5. Is there any 3rd party hardware available? should I wait for the next gen extreme? Don't know a lot about networking, I like the plug and play of the Airport hardware.
