Hello, this is a post about installing wifi on a debian 9.1
xfce. It comes as a complement for the https://wiki.debian.org/wl
which is the reference page for this driver.
I have an HP laptop with a b43142 wifi chipset, (info obtained
(The install has been made on a sd card, so that one does not alter the main hd.)
This bcm43142 is not free, and the driver module is not
included in the default debian kernel.
is the link to the module page package. Download the module
corresponding to the debian version.
Then dpkg -i nameofthepackage.deb (some other packages like the
kernel headers have to be present on the system, see the wiki)
I compiles well. Then as root, remove the conflicting modules
(see the wiki), and "modprobe wl",
Check that the module was loaded : lsmod | grep wl
wl 6443008 0
(everything seems Ok)
Enter in a shell "/sbin/iwconfig" and one should see a "wlo1"
interface. (it is not necessary to be logged as root).
If nothing happens, then enter manualy the name "wlo1" of the interface in the line "wireless network" of the network manager (Wicd by default for xfce) that was empty.I hope it can help, Enjoy !
