After the latest upgrade of Kernel til 4.13.12-1-default and the broadcom-wl-kmp-default corresponding version, wifi brake.
Now i didn’t get Sudo modprobe b43 to work either.
So i tried to downgrade kernel in Yast and removed the 4.13.12 and leave 4.13.10, but it just reinstall 4.13.12 again and problem resist.
I can wait til new fix on Kernel and Broadcom, but i tought i could downgrade. Isnt this possible?
Just want to report that i manage to fix the problem.
I did a mistake and upgraded the Broadcom-wifi-driver from x86_64 to i586. I see now the Broadcom-driver (x86_64) for Kernel 4.13.12 has not been released.
It was impossible to downgrade Kernel when the not corresponding Broadcom-driver was active. I reverse the Broadcom-driver to 4.13.10 and then downgrade Kernel to the same.
Now its working again.
