Issue #548 has been updated by Walter Sonius.
Works for me on X201, not sure if its the same ac-7260 adapter, have you tried the other internal mini-PCIE?

---------------------------------------- Bug #548: Lenovo X201 Fails To Recognize Upgraded WiFi Card https://ticket.coreboot.org/issues/548#change-1943
* Author: Jeremy Brown * Status: New * Priority: Normal * Target version: none * Start date: 2024-07-15 ---------------------------------------- I am running coreboot 24.05 on my Lenovo X201.
I decided to upgrade my WiFi card from an Intel Centrino Advanced-N 6205 to an Intel Wireless-AC 7260; since I selected the option to support Intel PCIe cards in my build config I expected everything to work but my computer fails to recognize the new card. The old card is still recognized if I reinstall it so I know I didn't mess up the socket somehow; I've read reports of the 7260 [working with a modded factory BIOS](https://richbits.rbarnes.org/installing-the-intel-7260-in-the-thinkpad-x201....) so I don't think there's an electrical issue. I've seen [somewhat related bugs](https://ticket.coreboot.org/issues/311) but it seems their issue isn't mine.
I've attached lspci data from both chips and my build config, lmk if additional information is needed.
