Original Apple 11Mb/sec 802.11b Airport wireless networking card for older Apple laptops and desktop. See below for a list of Apple models that require this type of Airport card. These computers cannot take the newer Airport Extreme card and can only support wireless using the original card which Apple stopped manufacturing some time ago.
Being 802.11b standard compliant means that this card is fully compatible with 3rd parts routers and wireless access points as well as Apple's own Airport base stations.

This card is used and fully tested, and is supplied with 6 months warranty against failure.
