[x] ERROR: Failed to open 'mon0' for capturing

I am trying to learn how to do WPS attacks, you know to test network security. I have been following a tutorial on-line. I'm crazy new to all of this so I don't really know what I'm doing.

I have a ASUS K50IJ 4gb ram it has a Qualcomm Atheros AR9285 PCI-E rev1 in it. its using the driver ath9k which all the Linux forums say is the correct one for that chipset. oh and the OS is Kali 2.0

root@Kali:~# airmon-ng
PHY Interface Driver Chipset

phy0 wlan0 ath9k Qualcomm Atheros AR9285 Wireless Network Adapter (PCI-Express) (rev 01)

root@Kali::~# airmon-ng start wlan0
Found 5 processes that could cause trouble.
If airodump-ng, aireplay-ng or airtun-ng stops working after
a short period of time, you may want to kill (some of) them!

I have read many posts that say to use the cmd "sudo" to get around that error

root@Kali:~# sudo wash -i mon0

so yeah I'm not sure what to try next to get this working
(also I run "service networking start" and "service network-manager start" but my network connection never comes back so i have to restart the whole comp, is there a faster way to get but up?)
