How to set up the wifi ? ( 13.2 KDE, 32bit )

sseebbyy · February 26, 2015, 3:03pm

Hello, openSUSE comunity !
I never used this OS before, so I have no big idea about how things works.

I recently installed v13.2 32bit on my brother’s laptop, because I really think it works faster than Win7 32bit.
It really looks cool, I like it, and it also works faster, but I have a problem: Wifi is not working.

It is not showing up like in windows7, by default.
All I see is that black cable, with a little red X in the bottom of icon. It says “NetworkManager not running”.

So my question is, how do I set up the wifi connection ? I want a detailed explication exactly for 13.2 KDE, please.

Thank you very much !
Have a good day.

This is unusual. Normally the installer recognizes that the computer is a laptop. Apparently it missed in this case.

Yast → Network Devices → Network Settings

Click the “Global Options” tab.

Look for “Network Setup Method”. It is probably showing “Wicked Service”. Switch that to “Network Manager Service”.

Then click “Continue” or “Finish” near bottom right.

After that, you should be able to configure WiFi with the tray icon.

Thank you very much for replying !
I did all you said, but after I clicked on “Finish”, I got a message that was telling me to have
I clicked “ok” even if I’m not sure if I had that thing opened… my brother removed that white window with few apps from the desktop (no idea how to reopen it), and I got an error saying that the Network is not available, or something like that.
I clicked on ok… then wanted to give it a second chance, but when I opened the Network Settings, I got this message: “Warning ! Network is currently handled by NetworkManager or completely disabled. YaST is unable to configure some options.”

What should I do ?

In the Global Options, that “Enable IPv6” is marked, at “DHCP Client Identifier” is nothing written, and at “Hostname to Send” is written “AUTO”.
Also, the “Change Default Route via DHCP” is marked, and looks like unmarkable.

As nrickert told you: use KDE’s networkmanagement icon in the system tray to setup your wireless connection.
It should not show a red X any more.

sseebbyy · February 26, 2015, 10:01pm

I have absolutely no idea what should I type, and where, in setting the wireless…
Can you please tell me that ?

PS: I have plugged in the cable, and the network works fine, but I want the wireless to work.

wolfi323 · February 26, 2015, 10:49pm

Click on the icon, and you should see a list of networks. Click on one to connect, you’ll then be asked for a password if necessary.

If you don’t see any wireless networks then your wireless card is probably not working at all.
In that case, please post the output of “/sbin/lspci -nnk” (or “lsusb” if it is an USB device) so that we know what model it is.

nrickert · February 26, 2015, 11:03pm

You need to look for that icon in the tray. It should not have a red X any more. It might have changed appearance. I think it looks like a wire with a connector in the middle, or it looks like the WiFi indicator on android cell phones. If not sure, hold your mouse over each tray icon until it tells you what it is for. Find the one that seems to be network related. Then click that, and see if there are WiFi options.

It is possible that your WiFi card is not recognized by the linux kernel. So post the output from


/sbin/lspci -nnk

Use code tags to post the output. You can generate code tags with the “#” icon in the forum edit window, then paste the output between those.

Fraser_Bell · February 26, 2015, 11:20pm

On the right hand side of your panel/tray (the bar across the bottom of your screen, if you have not changed its position), there is a network icon:

This dialogue, or similar, should pop up:

The picture was done with internet cable pluged in. When it’s not connected to the internet, a little red x appears under the network icon.
Tell me if you need more pics.

You found the right tray icon for wireless settings.

There are several possibilities. One possibility is that the wireless is blocked. This can happen if you use a key combination (often FnF2) to turn off WiFi in Windows. The fix for this is to boot to Windows and make sure that it is turned on. Or see if that same key combination works in opensuse.

Another possibility is that your card isn’t being properly recognized. This could be because you need the firmware. The quickest way to solve this is to install the broadcom-wl driver from Packman.

If you don’t already have the Packman repo configured, then do that first. You can do that with Yast → Software Repositories, click on Add, then check the box for Community repos. Then select Packman and hit Okay (or Finish or whatever it is).

If you have Packman configured, then use Yast → SoftwareManagement. Type “broadcom” in the search box and hit search.

You will need to install: “broadcom-wl” and “broadcom-wl-kmp-something” where the “something” matches your kernel. If you have the default kernel installed, use “default” there. Or “desktop” if you have the desktop kernel installed. You can find which kernel you are using with the command

uname -a

This doesn’t work out of the box.

You could install the proprietary broadcom-wl driver as nrickert mentioned already.

It should also work with the included b43 driver, but you would need to install additional firmware (that cannot be included for legal reason).
You can get the firmware by installing the package “b43-firmware” (also available on Packman), or by manually downloading/installing it as instructed here: http://linuxwireless.sipsolutions.net/en/users/Drivers/b43/#openSUSE

wolfi323 · February 27, 2015, 11:36am

You should be able to choose “Community Repositories” there.
Strange.

So no more clicks for me here…
Then I wanted to see the Software Management, and I got this:

To get rid of this dialog, you should remove/disable your installation medium (the 3rd one in your list).

No, there are no updates selected.
You’d need to add the Packman repo first to see the necessary packages anyway.

As you don’t seem to be able to choose “Community Repositories”, just enter the URL manually:
http://packman.inode.at/suse/openSUSE_13.2

Or just run this commands instead (taken from the link I posted) and your wireless should work after a reboot:

sudo /usr/sbin/install_bcm43xx_firmware

sseebbyy · February 27, 2015, 2:25pm

You are talking about that error that appeared, and I skipped ?
If yes, about what list are you talking about ?
(if you can, reply with my pic, edited)

Finally !!
It works like charm now. Really, thank you very very much !!

wolfi323 · February 27, 2015, 3:44pm

The repo list in YaST->Software Repositories, right when you open it:
http://s28.postimg.org/e85yz28y5/snapshot3.png

Delete or disable (i.e. untick the “Enable” checkbox) the 3rd entry (“openSUSE-13.2-0”), or you will be asked to insert that USB stick every time you open YaST.

sseebbyy · February 27, 2015, 5:24pm

Done
Thank you very much again, for everything !
This is what I call a real support.

I wish you good luck in everything, have a nice life.
See’ya
