Hi, All:
Got an issue when using "iw" to configure my WIFI card.
Issued a scan command and got a "command failed, operation not permitted"
Then changed to root as somebody suggested to do it again, it got worse and said network down. See below for screen capture:

spirent@coast198:~$ iw dev wlan0 scan
command failed: Operation not permitted (-1)
spirent@coast198:~$ su
Password:
root@coast198:/home/spirent# iw dev wlan0 scan
command failed: Network is down (-100)

System set up:
Running Ubuntu 13.10 server version, using a mini PCIe card with QCA9880 chip (ath10k driver should be in 3.11 kernel release).

Can somebody tell me what's wrong?

Thank you!

Nick Shu
