SOLVED - BCM4352 wireless card problem

Good day to everyone, I'm a happy Devuan new user. After I tested this distro on my desktop computer now I am trying to get everything working on my laptop too.

This is the first real issue.

After the installation seems that wifi card not working.

lspci output give me my wifi card

01:00.0 Network controller: Broadcom Limited BCM4352 802.11ac Wireless Network Adapter (rev 03)

I googoled for the drivers and seems that I have to install this package


https://wiki.debian.org/wl#Installation


So I follow instructions.
Now it's time to configure the network correctly, so I follow this guide


https://wiki.debian.org/WiFi/HowToUse


Wicd section before, without success.

From the command line I have this outputs:

~# ip a

RTNETLINK answers: Operation not possible due to RF-kill

seems there is an RF-kill problem.

~# rfkill list

	Hard blocked: no
2: hci0: Bluetooth

3: phy0: Wireless LAN

Wonderful.

~# rfkill unblock all

I obviously posted only my wifi internet

The man page tells me I have to edit

/etc/network/interfaces

Ok now I am a bit tired. I don't understand how the interface is brought up automatically during boot up, I am not sure how to edit this file and I am no more sure this is the right way to make my wifi working.

Why Wicd doesn't work, for example?

Could you give me any advice or help?
Thanks in advice.

Enable the networking service to run the ifupdown scripts automatically at boot.

Define "right". I much prefer /etc/network/interfaces over wicd or ceni, but then I prefer systemd-networkd over ifupdown so...

Please describe how you are attempting to make it work and what exactly happens when it doesn't work. Check the logs for errors and post them here if you can't figure out what they mean.

Re: SOLVED - BCM4352 wireless card problem

If you're using wicd or some other network manager, you should not configure /etc/network/interfaces. They will fight with each other if you do.

The most common cause for wicd to fail to see the wireless interface is that wlan0 is not set as the default wireless interface in wicd preferences. Maximize the wicd window and you'll see where to get to Preferences. (Or click on the little arrow if you can find it.) It's also possible to set the wireless interface in /etc/wicd/manager-settings.conf -
wireless_interface = wlan0

This works and that's what i was asking about the "doing right" thing.

Now the only issue is that I have to click the "Switch on Wi-fi" Wicd Network manager button every time I turn on my laptop.
