Hi guys i finally got my wireless network card detected today. So i can see the card with 'ifconfig' (wlan0) but i'm not able to sucessfully get the card to grab an ip from my router.

When i try to grab an ip
'dhclient wlan0'

it doesn't output anything and when i go look the wireless card doesn't have an ip.


Info Distribution: Debian 7.1 (wheezy)
Wireless Card: Intel Centrino Advanced-N 6230

/etc/network/interfaces (wlan part)

auto wlan0
iface wlan0 inet dhcp
wpa-ssid MyWirelessLan
wpa-psk MyWirlesslanKey

If i do a 'ifdown' followed by 'ifup':

Could be a driver problem.
Your card should be supported through iwlwifi as stated on the intel website.
Easiest thing is to try apt-get update your system, if that does not help you could add the testing and/or backports repositories to /etc/apt/sources.list and try update again (relevant package is firmware-iwlwifi. the package in the various repositories can be found here without adding the repos to sources.list).
Otherwise you could try to download and install the latest drivers manually from here.
Hope it helps
