Issue #445 has been updated by Masc Masc.
I would like to add a latest update. I have been having the wifi card problem intermittently and I decided to change it. I purchased another Atheros AR5B95 and so far the problem seems resolved (I have been testing it for a few days and the issue seems gone), supporting the idea in Martin Roth's post.
---------------------------------------- Bug #445: Thinkpad X200 wifi issue https://ticket.coreboot.org/issues/445#change-1418
* Author: Masc Masc * Status: New * Priority: Normal * Target version: none * Start date: 2023-01-06 * Affected versions: 4.18 ---------------------------------------- Compiled coreboot latest revision from source and built a coreboot rom image for X200 with SeaBIOS (also tried with Grub as a payload). The laptop beeps and the power LED flashes at startup and the wifi card does not work (cannot enable wifi in OS). The operating system is Debian Bullseye and the wifi card is an Atheros AR5B95. The OS boots normally, but no wifi is available. The wifi card has been tested and works fine with latest stable libreboot release.
