I bought a D-link DWL-122 USB wireless card.

I had it working all ok, with encryption etc. But after a short time of use my system locks up, no mouse movement no keyboard input.

update a few days ago when I went looking for the most recent driver their site linked to version 1.3.2. but it still crashed

then I found a newer version at MacUpdate - 1.4.7


I've had it installed for over 8 hours and not a freeze nor a kernel panic so far.

hope this helps you out.
