[gentoo-user] broadcom-sta for my wireless card

[gentoo-user] broadcom-sta for my wireless card

[allan gottlieb]

My older laptop needs broadcom-sta.  Back when I bought and setup the
laptop (kernel 3.18.12), I emerged broadcom-sta and wireless worked.

Now I am upgrading to kernel 4.9.16.  The kernel boots but no wireless.
In /lib/modules/3.18.12-gentoo-3 I have net/wireless/wl.ko.
In /lib/modules/4.9.16-gentoo-3 there is no net.

Am I supposed to remerge broadcom-sta?  If so how do I indicate the
kernel version for /lib/modules?
   Do I set the the /usr/src/linux symlink?
   Do I run 4.9.16 during the emerge?
   Something else?

thanks,
allan

Sounds like it installs kernel modules, so yes, after a new kernel build
you need to re-emerge all packages that install modules. Easiest way to
emerge all packages that install kernel modules is:

`emerge -a @module-rebuild`

Thank you dan, but how do I tell the build which /lib/modules/* to use.
I gave two guesses above.

it installs according to the /usr/src/linux symlink

Use `eselect kernel list` : it will show which /lib/modules it will go
to (as an example here's mine):

$ eselect kernel list
Available kernel symlink targets:
  [1]   linux-4.1.37-gentoo *
  [2]   linux-4.9.16-gentoo

If I merge a package with kernel modules, it will currently go to
lib/modules/4.1.37-gentoo, which is what my kernel symlink is set to.
You can use `eselect kernel set` to change this symlink. In my case,
using `eselect kernel set 2` will change it to 4.9.16. In your case,
list the installed kernels and set it to the new kernel and `emerge -a
@module-rebuild` and you'll be good to go.

Or you can set the symlink USE flag for your kernel package and it will
automatically set the symlink to the most recently installed kernel.

Thank you all.
