Connecting Pc to Mac Wirelessly


I have just bought an Imac G5 2.0 Ghz/512MB/250Gb/Super-drive/Airport/Bt/20" This i have connected to the Internet via a Belkin ADSL Modem / Wireless-G Router all successful.

Now I want to connect my Dell Inspiron 8100 running Windows 2000 via a Netgear 108Mbps Wireless PC card. I've installed the Netgear software, and the PC card.

But it seems not so easy as the Network connection, can you help me to connect the PC wirelessly so that I can share the Internet & printer connection on the Imac. The printer is an Epson Stylus Photo R300.

I am quite new to networking wirelessly or ethernet, so don't assume that I know please.

Thank You
