[SOLVED] Dell XPS15z no wireless Intel Centrino Advanced-N 6230

erbey · 2012-04-08 15:20:45

Hi, I have just installed arch on my dell xps15z everything is going well exept my wireless isn't working at all.

dell xps15z wiki says that wireless should work fine so I am a bit confused. I have wireless_tools and network manager installed.

iwconfig looks like its saying there is no power to the wifi. But I'm not sure if thats the case and if so how i force it to give the module power. I do have a keyboard shortcut to turn power on and off to wifi and in Ubuntu it works and turns both bluetooth and wifi on and off but in arch it only turns bluetooth on and off while wifi seems to be constantly off (if that is the reason wifi isn't working).

Wifi does work in ubuntu and windows its just arch thats having the problems by the way.

network manager isn't in the top bar but if i open it it doesn't show any connections or let me add any. But i can connect to the internet with ethernet even though network manager doesn't show it.

can anyone offer any advice? I am new to arch but have been on ubuntu for a few years and decided to give arch a go and learn a bit more about linux in general.

If you've just installed Arch with the new 3.3.1 kernel then that is likely causing the wireless problem. Several people , including myself, are reporting issues with Atheros wireless devices under the new kernel. Seems to be an issue with the Atheros 3.3.1 kernel module and not Arch itself.

Except that he has Intel...

You should follow the generic instructions for getting wireless to work first. If that does not work, you can - with certainty - say there is a problem with your wireless; until then, it could be everything.

firstly thanks for the replies. Sorry I hadn't tried the manual setup, but I still had no luck

iwconfig wlan0 mode ad-hoc (even though i know i don't want ad-hoc)

 
Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0 ; Operation not permitted.

ip link set wlan0 up ( ihoped this might give the module power)

 
RTNETLINK answers: Operation not permitted

iwlist wlan0 scan

wlan0     Failed to read scan data : Network is down

Are any of these outputs giving any hints?

You ran the commands as root right? The firmware is installed? Does dmesg show anything interesting?

erbey · 2012-04-08 19:53:29

Sorry everyone. I figured it out. I forgot to add network manager to the daemons section of /etc/rc.conf. Everything works perfectly now. Sorry for wasting anyone's times and thanks for the responses.
