Hi guys, this is my first post here and I am in search of procedures to set up Airport!Well, I want to setup an Airport Connection with the BSNL Router WA3002-g1 and I don't have a Airport Express card. My ethernet card is Based on Realtek 8139 chipset and my router is also connected via ethernet port. Being a noob on this regard, I just know that Airport is some kind of Wi Fi access for MAC OS X. How can I set up the connection ? If I have to buy some other hardwares then please specify.I am running MAC OS X 10.5.1Please help me here.
