I have a Powerbook G4 1.67Ghz running MorphOS 3.20. The Airport is extremely poor, downloads are about 128kB/s max, uploads are maybe a 10th of that or less. In MacOS 10.4 it works fine. Sure its an old card, but it does proper speeds. Same in Linux. I have tried to toggle the loopback interface as others suggested. I have tried completely Open SSID, with no security. It doesn't matter, its just so slow this cannot be the "normal". Are there open issues/bugs on the Airport driver? I have an Atheros card coming, but it would be great to use the built in Airport. Ethernet works fine.
