Hey All, I had followed and read up on all the websites as well as forum posts on doing this upgrade. But i have realized this...if i shutdown the computer for a while (Not sleep) and reboot, the dell 1500N wireless card appears to be working. But when i go and restart the computer, it dissappears and any restart after the first time i turn on the system from a complete shutdown, the airport card is undetected. By the way, i have used pacifist to install the airport extreme 2007-002 as well as 2007-003 updates but still have the same issue. Anyone have these issues or can shed any light on what i should do? The dell 1500 card that i have are the following: Wireless Card Type: AirPort Extreme (0x14E4, 0x87) Wireless Card Locale: USA Wireless Card Firmware Version: 126.96.36.199 Thanks for your help or comment.
