BCM43142 configuring problems

edrom · 2019-02-19 21:24:35

Hello!
I just installed Arch and have problems with configuring my wifi adapter. I do not consider myself a newbie, because about a year ago I used Arch as the main system. And in it time I figured out with wireless configuration, but now get failed.
So let's get closer to problem.

I have installed broadcom-wl-dkms with dkms as dependency. I have runned mkinitcpio -p linux and installed missed firmware. But still getting failed.

About basic info which I can share with you:

$ lspci -k

        Subsystem: Hewlett-Packard Company BCM43142 802.11b/g/n
        Kernel driver in use: wl
        Kernel modules: bcma, wl

$ ip link

    link/ether d8:5d:e2:bb:d6:6b brd ff:ff:ff:ff:ff:ff

$ iwconfig

Work methodically through the wireless page, and post the exact error messages: "still getting failed" is not helpful.

Moving to NC...

You are right, I probably did not describe my problem in very detail. I just tired after half of day trying to configure it by myself.

I will refer to the outputs listed above. As I see from lspci and iwconfig driver installed proper, but in Ip link I have state unknown for wireless adapter. And when I trying to find WiFi points via iwlist wlp19s0 scan I getting empty result (no scan results). And to addition KDE doesn't detect my adapter.

The output listed above says the interface is up and has a carrier, ie. you should be connected to an AP.

Ensure to stop all network managing services, post the output of "systemctl list-unit-files --state=enabled" and

that means to attempt a manual connection to figure which step fails (and why)

Also see https://bugs.archlinux.org/task/61119 and figure whether that's relevant to your current installation.

seth, first of all thanks a lot for reply.

$ systemctl list-unit-files --state=enabled
UNIT FILE               STATE  
autovt@.service         enabled
display-manager.service enabled
getty@.service          enabled
slim.service            enabled
remote-fs.target        enabled

5 unit files listed.

According to the guide:

This "guide": https://wiki.archlinux.org/index.php/Wi … figuration

You seem to have no network managing services enabled, so what brings the device up and establishes the carrier? How do you establish a network connection on (from the ip link excerpt, I'd guess there's) the wired interface?
"BROADCAST,MULTICAST,UP,LOWER_UP" doesn't show up there by magic.
Start from an unconfigured interface and log commands and outputs from attempting to bring it up, associate w/ an AP and get a lease.
I would assume you're trying to wpa_supplicant and that somehow fails, but we don't know anything about the problem yet.

At very least, post a complete journal (sudo journalctl -b) for the boot.
