iwlist wlan0 scan returns no scan results.

Just a remark. When you run the "iwlist scan" as a user you'll receive cashed results only. To trigger the scan you have to run the command as a root.

If I then press the wireless button, and run the same command again it will return the actual list of available networks Some other times, pressing the button does not make a difference and I'm forced to run the command: rfkill unblock all

It would be good to see the output of the command "rfkill list all" when you can not connect. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

On a normal startup, iwlist wlan0 scan will find no wireless networks and rfkill will display the following:

rfkill list 0: phy0: Wireless LAN Soft blocked: no Hard blocked: no

"iwlist wlan0 scan" shall be run when the adapter is UP.

Nevetheless, the wireless light blinks showing activity (this did not happen on 11.2). Pressing the wireless button will make the wireless work.

What adapter is it ? Would it be possible to post the output of "hwinfo --wlan" ?

Earlier, if I tried to bring up the device instead of pressing the wireless button, like by doing: ip link set wlan0 up I'd get soft blocked yes or some times both yes.

It would be better to use either NetworkManager or ifup/ifdown to bring the adapter UP/DOWN instead of using "ip link set wlan0 up". This can be configured it yast2 network settings. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

zeus:/ # ifup wlan0 Network interface is managed by the NetworkManager -> skipping

Would it be possible to switch to ifup/ifdown in yast2 network settings ?

zeus:/ # iwlist wlan0 scan wlan0 Interface doesn't support scanning : Network is down

The interface can not scan when down. Try to bring it up with ifup, ifconfig or ip .

zeus:/ # iwlist wlan0 scan wlan0 Interface doesn't support scanning : Network is down The interface can not scan when down. Try to bring it up with ifup, ifconfig or ip .

I posted this because earlier, if you noticed, iwlist wlan0 scan will return "no scan results" until I pressed the wireless switch (after the laptop was first switched on) but after trying to bring the interface up with ifup it returns that the interface is down. So why is it returning "no scan results" in the first place? Is the interface up but not working because of another problem? Is it down but iwlist doesn't realize it? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

Also, after this error comes up, I can't bring up the interface not with the wireless switch nor the rfkill command. By then, the hardware block won't go away.
