Hi All- So I have OSX installed and running very smoothly on 10.5.6. I replaced the Atheros card with a DW1390 card before I installed MacOS (iAtkos image) and for the first few boots the card was working great on Wifi. Then the wifi stopped working after I booted up, but it would still show the card as installed. So when booting I would use the physical switch to activate the wifi - the LED would turn on and everything would work fine. Now a few boots later OSX says there is no airport card installed at all and I can't activate it at all using the switch - the LED never comes back on. Has anyone else experienced this issue? Any thoughts on how to resolve? Thanks for any insight! Andy
