No Wi-Fi Network on SLED-12

SUSE Linux Enterprise Desktop SLED Networking
1

Hi All,

I’m using SLED-12 x86_64. Today, when I’ve started my laptop, I’ve noticed that System didn’t detect any Wi-Fi Network. But Lastday it worked well, and I didn’t install/remove any system pacakges.

Currently, If I’ll Click ‘Select Network’ from the wi-fi it says ‘no network’ Please see the attached Image, but I can turn on/off the wifi. That means the wifi is enabled.

can any one please help me to figure it out.

I’ve installed the wi-fi driver using ‘broadcom-wl-6.30.223.141-3.19.src.rpm’ downloaded from the http://packman.links2linux.org/package/broadcom-wl/410485/all Then compiled it & installed it.

Please some one help, it’s very very urgent.

Hi
Haven’t bumped the wireless key (Fn key) on the system, or does it have a switch?

Is the driver loaded?

/sbin/lspci -nnk |grep -A3 Network

Hello Malcolm,

yes wifi on-off fn key is present, & it’s on.

Hi
You need to also blacklist the ssb driver… as in add it
to the /etc/modprobe.d/broadcom-wl-blacklist file.

Hello Malcolm,

I’ve found one file, 50-broadcom-wl-blacklist.conf, inside ‘/etc/modprob.d/’ directory and the file has bellow lines::

# modules blacklisted for broadcom-wl
blacklist bcm43xx
blacklist ssb
blacklist b43
blacklist ndiswrapper
blacklist brcm80211
blacklist bcma
blacklist brcmsmac

And also note that, my wifi is running, but no network is displaying, which I can connect.

Can you help me

Thanks,

Hi
Fire up YaST and under Network Devices, check on the ‘Global Options’
tab in the ‘Network Setup Method’ is set to NetworklManager Service.

Hello Malcolm,

I’ve checked, and yes it’s set to NetworklManager Service.

One another thing, I’ve tried, from the wi-fi settings, Hidden wi-fi network, click the connection dropdown & found previously saved network, then select the one & then click connect, but nothing happen
.

Thanks,

Hi
If the ssb module is active then in won’t work;

Try;

rmmod -f ssd wl
modprobe wl

Hello Malcolm,

linux-26oq:~ # rmmod -f ssd wl
rmmod: ERROR: could not remove 'ssd': No such file or directory
rmmod: ERROR: could not remove module ssd: No such file or directory
linux-26oq:~ # modprobe wl
linux-26oq:~ #

Nothing happen, what your thoughts.
I’m using SLED-12 form last 3 weeks, & this is happening from last week.

Hi
Oops, a typo it should be ssb (playing with SSD’s as well today…lol)

An update, maybe with glib or the kernel…
