I have a Powerbook G4,867 Mhz. TI, Running OSX 10.4.8. No Airport or cards installed. I am using a Westell DSLWireless Modem with cables upstairs. I would like to take my PB downstairs and be able to go on line. I was told the airport card is no longer available. What options do I have, say with a USB WiFi ? What about a USB Flash Drive,Bootable. Thanks john
