creatxr · January 29, 2025, 6:19pm

loss BCM43142 wifi card after update:

i have two wifi cards, one is internal BCM43142 wifi card, the other is usb realtek wifi card.

after updated, i found that under the wifi drop-down list or with ifconfig command, it cannot find the BCM43142

with command lspci : 03:00.0 Network controller: Broadcom Inc. and subsidiaries BCM43142 802.11b/g/n (rev 01)

and i 've also re-install the driver with sudo pacman -S broadcom-wl-dkms with no error but some warnnings:

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.

johnf76 · February 4, 2025, 4:01pm

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?

naim · February 6, 2025, 1:15pm

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

johnf76 · February 7, 2025, 4:54pm

Thank you!

johnf76 · June 3, 2025, 3:59pm

It happened again. Lost BCM43142 wifi after update to kernel 6.12.30-1-cachyos-lts. I’m running Thinkpad X131e (I’m using an external Panda wifi card to connect, works fine, so it’s a problem with the new BCM43142 driver, as the old one worked).

I’m ok waiting for a fix, just wanted to let you know. Thanks!

naim · June 3, 2025, 5:08pm

Can you post the dkms build log? Another user reported this too with the latest LTS kernel.

johnf76 · June 3, 2025, 5:34pm

I think this should fix it.

Thanks! I’ll test it once the patch goes through as part of updates.

johnf76 · June 6, 2025, 9:11pm

Just got the update, installed and rebooted. I’m back online with the BCM43142. Thanks!!
