Hi all,
My laptop is Thinkpad T550 with an Intel Wireless 7265 net card. My
system was upgraded from opensuse 13.2 and it worked smoothly for half
years after upgrading to Leap 42.1. Yesterday I did a upgrade as usual
and after that my wireless network did not work. I tried to figure out
the problem, and found that the NetworkManager might be the reason. The
reason I draw this conclusion is that not only using the plasma applet of
NetworkManager but also using nmcli as root user I cannot scan the
wireless net, as show below:
nmcli device wifi rescan
Error: Scanning not allowed while unavailable or activating.
Meanwhile, when I use iwlist scanning I got the output like this:
ThinkSuSE:/home/ibex # iwlist wlan0 scanning
wlan0 Scan completed :

(the output is length, I only paste the first cell here.)
I even can use wpa_supplicant and dhclient to get an ip address on my
wireless card, as:
wpa_supplicant -i wlan0 -c ./wpa_config
dhclient wlan0
however, after all this I still cannot ping any address in WWW, while by
the wired net card it works as before.
I also checked the log of systemd by
systemctl status
and find the NetworkManager complains as :
NetworkManager[1108]: <error> [1456047017.557955] [supplicant-manager/nm-
supplicant-interface.c:737] interface_add_cb(): (wlan0): error adding
interface: Timeout was reached
NetworkManager[1108]: <info> (wlan0): supplicant interface state:
starting -> down
Is there any one who can give me some suggestions? Thanks.
