[SOLVED] ifconfig interface flag RUNNING is not set

Hello,

I'm trying to install OLSRD on some Intel Galileo's. Somewhere in the progress it says:

Code:

Checking wlan0:
    Interface not up & running - skipping it...

Checking ifconfig I see that it says "UP", but I can't seem to figure out why my wlan0-interface isn't "RUNNING". Most solutions on the internet mention something about checking your cables and such (because they have issues with a wired Ethernet connection) but that's of no importance for my wireless interface. Could anyone be of any help?

I have an Intel Centrino Advanced-N 6235 plugged in, which is working (I can ping other devices with it). Other information that might be useful are given below.

TLDR: How do I get my wireless interface to be "RUNNING"?

Code:

root@un:~# ifconfig wlan0
wlan0     Link encap:Ethernet  HWaddr 0c:d2:32:3e:22:42  
          inet6 addr: fd00::10/64 Scope:Global

          RX bytes:1526 (1.4 KiB)  TX bytes:1828 (1.7 KiB)

I adjusted /etc/network/interfaces to be the following, which solved the issue!

Code:

# The loopback interface
auto lo
iface lo inet loopback
iface lo inet6 loopback

# Wired interfaces
auto eth0
iface eth0 inet static
        address 192.168.2.10
        netmask 255.255.255.0
        broadcast 192.168.2.255
        gateway 192.168.2.1
        network 192.168.2.0

# Wireless interfaces
auto wlan0
iface wlan0 inet6 static
        pre-up modprobe ipv6
        address fd00::10
        netmask 64
        wpa-driver wext
        wpa-conf /etc/wpa_supplicant.conf

It now shows the "RUNNING" flag in ifconfig.

Code:

wlan0     Link encap:Ethernet  HWaddr 0c:d2:92:3e:20:42  
          inet6 addr: fd00::10/64 Scope:Global
