Intel Centrino Advanced-N 6205 not working on XUbuntu 11.4
Hey,
I just can't connect to a wirless Network using the build in networkdevice. The Networkmanger shows "device not manged". It has been connected to the network during the setup prozess.
Another usb Wirlesscard is working perfect (curently pluged in under wlan1) but I want to use the buildin.
Here are some Information's. If you need more just ask.

Re: Intel Centrino Advanced-N 6205 not working on XUbuntu 11.4
Please detach the USB wireless, make sure the wireless switch is set to ON and run and post:
Code:
rfkill list all
cat /etc/network/interfaces
cat /etc/NetworkManager/NetworkManager.conf
Thanks.
It is very confusing to try to sort the readings between built-in and USB, so when we are running diagnostics, please be sure the USB is detached.
Re: Intel Centrino Advanced-N 6205 not working on XUbuntu 11.4
Ok, i'll remove the externel one. But I need to replug it to post the results.
Code:
$ rfkill list all
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
Code:
$ cat /etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
I've just removed the configuration of the wlan0 out of this file. It doesn't make sense there, if I want to mange this with the Networkmanger. Thanks for the hint.
Code:
$ cat /etc/NetworkManager/NetworkManager.conf
[main]
plugins=ifupdown,keyfile
dns=dnsmasq
[ifupdown]managed=false
Now the Networkmanger print: "Device not ready".
Re: Intel Centrino Advanced-N 6205 not working on XUbuntu 11.4
So far, so good! Now, again with the USB detached, please let me see:
Code:
sudo iwlist wlan0 scan
Thanks.
Re: Intel Centrino Advanced-N 6205 not working on XUbuntu 11.4
The rusult:
Code:
$ sudo iwlist wlan0 scan
wlan0 Interface doesn't support scanning : Network is down
Edit: rebooting solved this error. @chili555: Thank's for your help and time. :)
