WiFi Appears to have been recognized correctly, however, no connections available

I’m really stumped. I’ve followed the stickied posts to try and troubleshoot the wifi but maybe I’m just missing something obvious. My wifi adapter is a bluetooth/wifi combo usb stick made by Cirago. It appears to have been recognized, the KDE network manager applet in the tray shows a wi-fi icon, however, no networks are found.

I installed Opensuse 13.2, kde and updated all the files with ethernet. I went into the Yast, and changed the network general settings to use NetworkManager instead of Wicked.

The bluetooth device works, but when I open the KDE applet, it does not show any networks (see screenshot).
The wifi device does indeed work as well, I’ve been using it with windows, and my raspberry pi OSMC installation.

Here’s the results from some troubleshooting:

Is there any other tests to try or simply obvious things that I’m not doing correctly?

If additional details are needed, please let me know I’m prepared to post more information as necessary.

Well, the KDE applet should at least show your interfaces, and the wired connection.

Something like in your screenshot only happens if NetworkManager is not running at all.

Can you please post the output of:

sudo systemctl status network

Thanks for taking a look. I actually don’t have a wired connection available right now, I’m currently typing to you from my windows install, however, when I installed OpenSUSE I did have it plugged in to ethernet, and the wired connection did show up nicely in the KDE applet like you mentioned.

Now for the output you requested:

Yeah, but still the interface should show up in the applet, even if there is no cable connected.

Now for the output you requested:

Ok, NetworkManager is enabled and running.

But the output is a bit short.
It seems to me that it is hanging when preparing the devices.

We had a similar case recently:
https://forums.opensuse.org/showthread.php/507894-Wireless-not-working?p=2719020#post2719020

There, blacklisting the ideapad-laptop kernel module helped. So maybe try that.
Disabling Bluetooth has been suggested as well, but I don’t know how you would do that with your USB adapter…

Thanks for the suggestions. I tried blacklisting the module by creating a file idea-laptop.conf


gregg@linux-wk7a:~> cd /etc/modprobe.d/
gregg@linux-wk7a:/etc/modprobe.d> ls
00-system.conf               50-blacklist.conf  50-ipw2200.conf  99-local.conf
10-unsupported-modules.conf  50-bluetooth.conf  50-iwl3945.conf  idea-laptop.conf
50-alsa.conf                 50-fglrx.conf      50-prism54.conf

and placing inside it:

blacklist ideapad-laptop

After rebooting, no effect seemed to happen.

Another thing I noticed after unplugging the device dmesg gave a bunch of errors (maybe relevant):

I also tried disabling bluetooth using the KDE bluetooth to turn it off. Neither seemed to have an effect.

I really don’t know what the issue is or what to try. I guess I’m fairly incompetent when it comes to configuring linux on my own. Does anyone have any other suggestions to try?

Have you tried to not connect your bluetooth device at all?
Or is this a combo device (bluetooth and wireless)?

Please post the output of “usb-devices” to find out the bluetooth “driver”. Blacklisting that one might help too.

Hi wolfi323! Sorry for the delay.

Yes, you’re correct. The device is a combo device with bt and wireless in the same dongle.

The output of usb-devices was:

I really don’t understand why the device isn’t working, it seems to be recognized correctly and drivers installed. How would you recommend proceeding on this?

This seems to be your bluetooth device:

T:  Bus=03 Lev=02 Prnt=03 Port=03 Cnt=02 Dev#=  6 Spd=12  MxCh= 0
D:  Ver= 2.00 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs=  1
P:  Vendor=0a12 ProdID=0001 Rev=68.17
S:  Product=CSR BS8510
C:  #Ifs= 2 Cfg#= 1 Atr=e0 MxPwr=0mA
I:  If#= 0 Alt= 0 #EPs= 3 Cls=e0(wlcon) Sub=01 Prot=01 Driver=btusb
I:  If#= 1 Alt= 0 #EPs= 2 Cls=e0(wlcon) Sub=01 Prot=01 Driver=btusb

So I would try blacklisting the btusb module and reboot.

Okay, so I added the line to my ‘/etc/modprobe.d/50-blacklist.conf’:

blacklist btusb

and rebooted. This didn’t have an effect on the wifi status. The output of that device from usb-devices changed to:

T:  Bus=03 Lev=02 Prnt=07 Port=03 Cnt=02 Dev#=  9 Spd=12  MxCh= 0
D:  Ver= 2.00 Cls=e0(wlcon) Sub=01 Prot=01 MxPS=64 #Cfgs=  1
P:  Vendor=0a12 ProdID=0001 Rev=68.17
S:  Product=CSR BS8510
C:  #Ifs= 2 Cfg#= 1 Atr=e0 MxPwr=0mA
I:  If#= 0 Alt= 0 #EPs= 3 Cls=e0(wlcon) Sub=01 Prot=01 Driver=(none)
I:  If#= 1 Alt= 0 #EPs= 2 Cls=e0(wlcon) Sub=01 Prot=01 Driver=(none)

How should I proceed?
