Use the LTS kernel in the meantime. broadcom-wl must yet again be patched for 6.13. Tentative patch for broadcom-wl 6.30.223.271 driver for Linux 6.13-rc1 · GitHub There is an available fix but Arch hasn’t adopted it yet.

I ran into the same problem with the 6.13 kernel update, losing the b43 driver. What’s the best way to prevent updates from installing the new kernel until it’s fixed for this issue?

Do a system update, the fix has landed in repos.

Thank you!
