I just purchased an iBook for my wife this past Saturday. When I was going to buy it, I asked the salesman a question. I told him that I have a Linksys access point and a Linksys wireless access card. I used to use both the access point and card for my Sony Vaio laptop which I no longer have. He told me that I couldn't use the card for the iBook. That I had to purchase the Airport card, which I did. He told me that I didn't need to purchase and Airport Station. That the Linksys access point will work fine. He also asked me if it was 802.11b and I told him "yes". He said it's OK, the Airport card (802.11g) is backward compatible with 802.11b access point. But now I get the iBook, install the card, and the software and it doesn't see my PowerMAC which is the other computer it needs to connect to. I then asked they guy whom I sold the Sony laptop too to please bring the computer back to see if it would connect to my powermac and it did! Tried it agin with the iBook and it doesn't see the other computer which is the PowerMAC. Why is this not working? I'm I doing something wrong? Do I need to purchase an Airport Station???? Please! Someone help me in fixing this problem WITHOUT having to purchase and Airport Station.
