G4 10.4.8 compatible wifi dongle?

Is it a 700MHz/800MHz model, or a 1GHz/1.25GHz model?

If the latter, just get an 802.11g Airport Extreme card off eBay and upgrade to 10.4.11 (or better still Leopard)...

If the former, the card is only 802.11b (11mbps) and does not support WPA2 (and WPA support is flakey). I'd suggest a wireless ethernet bridge in that case, because the USB ports are only version 1.1, rather than 2.0, meaning speeds will be, at best, 11mbps.

+1 for the Airport Express. plus you can hook up a switch to it and get more devices on it.

Another recommendation for an Airport card.

I have an iMac G4 and I used a USB dongle for the longest time with it, and it just got to the point where I didn't want to fool around with it anymore. I don't know about all USB dongles, some might be decent, but the ones I tried were really unstable.

I have had several ones, mostly Belkin and different ralink chipsets. They often work right out of the box even on ppc. I suppose you don`t really know until you have it working. I have one with a separate antenna (bad reception at my desk) bought on ebay "Kasens G5000", worked right out of the box on a ibook G4 running tiger, and all stable.

What I did for my 700 mhz g4 imac was pick up a airport extreme 802.11g model off ebay for cheap and connected it up as an extension of my
airport network. Works great and even matches the look of the imac.
