Soo…
As I see, I am among the many with wireless problems…
Here’s the info that I gathered from terminal commands :slight_smile:
when I tried to check for firmware faults, the dmesg | grep firmware didnt do anything

sudo /usr/sbin/iwlist scan
wlan0     Interface doesn't support scanning : Network is down
 
lo        Interface doesn't support scanning.
 
eth0      Interface doesn't support scanning.

You might want to give the output of **dmesg | grep wlan

**Though another weird thing is it appears that driver is loaded. Perhaps you can make sure, as root run: modprobe rtl8187​ After which try restarting network manager.

#3

maybe I’m doing something wrong, but nothing happens when I type those commands… :confused:

#4

Nothing happen on the first one means nothing in the log relating to wlan. Nothing on the latter means it worked, and see if wifi shows up after restarting network-manager (or just disable enable networking I think).

The RTL8187B does not need external firmware. Everything is built into the device.

The “Network is down” message either means that (a) something is blocking the
wireless signal, or (b) wireless is disabled in NetworkManager.

When you post a question, ALWAYS state what version of openSUSE you use, and
what desktop you employ. We need that info to tell you what to do. In the
meantime, run the following commands:


sudo zypper install rfkill
/usr/sbin/rfkill list

Post the output of the second command.

I think wireles is working, but now I’ve been on windows pc :slight_smile: I’ll post the results as soon as I have free time to boot on linux :slight_smile:
