Airport card for Power Mac G4

Anyone know which airport card I need?

You need the original AirPort card or a PCI 802.11 card or an external component which provides the capability to use the 802.11 protocol.

An Airport card will obviously work but if you have space you can also buy a PCI wireless card. The trick is to get one that is Mac compatible. I have bought a couple off ebay. Just search for Airport card and you will also see PCI versions:

Here's an example from ebayUK. They are cheaper than the orginal airport card

Use extreme caution with third party PCI cards, as many support 10.3 and later ONLY.

If you get one specified for a Mac I find that they work fine. I have used 3 for different G4's with no problem. I paid a bit more to buy ones guaranteed for Mac rather than taking a risk with PC version and hoping the chip set was mac compatible. I have used them on 10.3, 10.4 and 10.5.

The advantage is that they can be faster than the original Aiport card that became very expensive after is was withdrawn.
