It is Lucent Technologies WaveLAN Silver. This particular card is good because it supports WEP. I've tested it under OS 8.1 and later and is detected automatically under those OSes. Just remember to make AppleTalk "inactive" and to change TCP/IP from "Ethernet built-in" to "AirPort card (under Apple logo > Control Panel > TCP/IP).
Here is a very informative piece on wireless cards compatible with Classic Mac OS: AirPort | 802.11b | 802.11g | Wireless FAQ For Older Apple ...
If you're running OS 9.0 you will need AirPort 2.0.2 from Apple's website (AirPort 2.0.2 for Mac OS 9). If you're running OS 9.2 you will need AirPort 2.0.4 from Apple's website (AirPort 2.0.4 for Mac OS 9: Information and Download)
AirPort will not run under OS 8.6 or earlier!
Keep in mind this card is "plug-and-play" with OS Classic 8.x and 9.x but if you were going to install under OS X 10.0 or later you need a program like WirelessConfig (AirPort | 802.11b | 802.11g | Wireless FAQ For Older Apple ...) to get it working under OS X 10.0 and later. Not natively supported AND not "plug-and-play" under OS X.
Hope this helps! That machine is a bit old. I would recommend Classilla (Classilla: Building a Secure Web Browser for Mac OS 9 and the ...) for modern browsing on something that old. However I use Safari on my PowerBook G4 and iMac since Safari is still updated for those platforms.
