Well it certainly isn't an Intel. G3s are PowerPC, which is why there is a PPC forum. Sadly no iMac G3 has a better WiFi than WEP/WPA1 128bit encryption 802.11b. So if you are in a location that needs to be secure, you are better off getting an ethernet WiFi bridge, and putting the iMac on the ethernet LAN port of that bridge. To find out if your iMac supports Airport 802.11b, see this article http://support.apple.com/kb/HT2256 Be sure to read the notes if you need an extra adapter.
