Okay, I just installed my Dell Truemobile 1450 today in 8F1111 with the 80122 kext added. It was detected as an Airport Extreme, but it said the link was down and I could not make it turn on. I played around with the airport commands in the terminal and then tried using iStumbler, and somewhere between the two, it grabbed an IP from the DHCP server as the built-in ethernet card. Everything worked fine, although the LED was not lit. After I rebooted, it no longer worked. Then things started randomly crashing, so I decided to format and reinstall. I installed 8F1099 and the LED lit up upon the first boot, it asked me which network to connect to, so I chose mine and it worked for a few minutes, and then the LED shut off once again. After that, I could not make it work. I have rebooted several times, but to no avail. Also, the airport commands no longer work in the terminal, assuming I'm typing them right. It says it cannot find such a command as "airport". At any rate, I do have an airport icon in the menu, but it says not configured and will not show up in the network panel. All I get is "built-in ethernet" (my real built-in ethernet card is not detected) and it will not grab an IP, nor will it function with a manual IP. The radio simply doesn't turn on.
