Hi @jtaczanowski Thanks for the great repo. This is not so much an issue, but more of an information for you and others using this repo.

Initially, I had trouble connecting to my wifi AP, and I tried different intel kexts, and discovered the following. Apparently both AirportItlwm and itlwm does not work for the intel centrino 6200 card. No matter what kext I used, both in Big Sur and Monterey. I also happened to own a Thinkpad X200 with the intel centrino 5300 card installed, so I tried to boot your EFI, and to my surprise, I was able to get to the installer and my wifi connection worked. Since the 5300 card is not in the whitelist for the X201, I couldn't test this card in the X201, but my guess is that it would work with a hacked BIOS.

Then I made a speculation. Perhaps the 300 line of intel cards work, and 200 line of cards do not work. I went ahead and bought an intel centrino 6300 card for my X201, which is in the whitelist. My speculation was correct! I was finally able to install Monterey on my X201 with the intel 6300 card fully working.

So the summary is like this: -intel 5300 works -intel 6300 works -intel 6200 not working

Hi @discus7l :) Thank you for sharing your insights :) I use 6300 model and unfortunately I don't have another with 200 card to test this issue. I don't see any restrictions about 200 cards in https://github.com/OpenIntelWireless/itlwm (kext for Intel WiFi cards) project It's hard for me to say what the problem could be.
