A newbie need help with WiFi

Hi everyone, i tried to undertand something by myself for days before write this post, since i didn’t want to make another annoying thread, but i didn’t manage to solve my problem.
As write on top, during the installation my wifi network card hasen’t been found. Ethernet is ok, instead.

I followed the sticky guides as far as i manage and this is the result:

/sbin/lspci

03:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)

/sbin/lspci -n

03:00.0 0280: 14e4:4365 (rev 01)

dmesg | less

21.153514] Broadcom 43xx driver loaded  Features: PNLS ]
21.157015] Broadcom 43xx-legacy driver loaded  Features: PLID ]

Any suggestion on what to do now?

Ideally you need a wired connection

Make sure you have this repo

su -
zypper ar -f http://packman.inode.at/suse/openSUSE_Leap_42.2/ packman

zypper ref
zypper in broadcom-wl broadcom-wl-kmp-default

I’ve just tried, i accepted and updated everythig, but the problem is still unresolved :\

Please post:

zypper lr -d
zypper se -si broadcom kernel

Here they are, thank you for helping

Report back with output from

/usr/sbin/hwinfo --wlan
/sbin/ifconfig

Are you using wicked or NetworkManager to manage your networking? If you’re not sure, run the following and report back

sudo systemctl status network

I don’t know what to say, i’ve just turned on my pc and wifi is correcly working. I did nothing more after the last attempt.
I guess that something has been applied after the reboot. Maybe it’s what caf4926 suggested. Can you explain me what does that code do?
Anyway, thank you all very much.

The commands that Carl gave you were to install the required driver packages. A reboot will allowed the appropriate driver to load and your wifi configuration to take effect.
