Wi-Fi doesn't work since 4.4.0-104

[alex]

since 4.4.0-104 kernels my Wi-Fi isn't working. It doesn't show up in Network Manager, wireless network device is not visible via ifconfig/ip a l commands, though, it's visible for lspci. I had to revert back to 104 kernel. Wi-Fi card is:

So wifi does work with 4.4.0-104, but not any kernels newer than that?

[Kai-Heng Feng (kaihengfeng)]

I guess this chip uses proprietary driver?
Please attach `dkms status`.

[alex (a-gerasymenko)]

Hi,

yes, I installed proprietary driver via Additional Drivers.

Should I run `dkms status` running *109 kernel?

Yes, please.

This command shows the same result from all kernel version.

Here is an output from `dkms status` command:

dkms status
Error! Could not locate dkms.conf file.
File: does not exist.

[Kai-Heng Feng (kaihengfeng)]

Try to reinstall broadcom-sta-dkms or bcmwl-kernel-source.

[alex (a-gerasymenko)]

Thanks,

reinstalling bcmwl-kernel-source made my wireless work.
