Got mine working!

osx 10.3.x
dwl-g122
rev B1 fw: 2.02
Drv1.0.7.0

Was there a trick to it? What steps did you go through?

Thanks!

Install the proper driver as mentioned above.
reboot
install usb device
wifi util will pop up (good sign)
launch network tool and it will show the detection of the new network device.
apply

then configure things as needed....

I couldnt get mine to work, but it picks up the network etc.. but wont connect. I have the G122 B1 version but a F/W 1.00 you mentioned yours were a 2.02 im not sure if the F/W would make a difference..

Are you able to give a more descriptive detail how you got yours to connect to network? thanks.
