Sager 8120 Intel Centrino N-6300 not connecting

Raphleon_Donangelo · March 6, 2011, 3:41am

Hello everyone,

Alright this is my first post on here and I hope I got sufficient Information for you available. I am not a complete newbie to Linux. I ran Ubuntu based Distros before but this is the first time under a Debian based Distro for me. I got a newlaptop and this one does not seem to let me get my wireless to work after multiple efforts so I hope I can find help here.

My problem: My Intel Centrino N-6300 (](http://www.intel.com/products/wireless/adapters/6300/index.htm)) does not seem to find any network connections.

My previous attempts: (Some of which required me to reinstall Suse)

I installed new kernels as my first assumption was that the kernel was not supporting it. I know now that it is supported.
I installed drivers from http://intellinuxwireless.org/ which was pointless.
I installed backports (THat was still under Linux Mint. Same problem there.)
I tried NDiswrapper without success.
I checked rfkill as you can see further down below.

Alright here are some of my info’s I have collected so far. Let me know if anything is missing.

RFkill:

Soft blocked: no
Hard blocked: no

Hi,

That is weird, it seems that the iwlagn is well supported… maybe I am wrong.

Could you go to YaST =>Network Devices => Network Settings. Under the “Global Options” tab, click on the “User Controlled with Network Manager” button.

If it is, can you post the result of :

hwinfo --network

Raphleon_Donangelo · March 6, 2011, 3:55am

Thankyou for the fast response. It is turned on and this is what I get:

Ok, the driver seems to be loaded. So, it is not a driver problem.

Since knetwork manager is working, when you click on it on the tray, you click on your ssid on did you entered the encryption key correctly ?

In root, can you post the result of this :

iwlist scan

Raphleon_Donangelo · March 6, 2011, 4:02am

Another note. The odd thing is that it gives me the option to Create a Wireless connection but even if I do that with the correct information it won’t connect. Nor does it show any networks when I scan for them. Thank you already for all the effort you put into this. I spend the past weeks trying to fiddle around with this on multiple distros. I truely wouldlike opensuse to run as it seems to be a fascinating distro. I also speak german if that helps any of you.

Raphleon_Donangelo · March 6, 2011, 4:03am

It won’t even show any SSID’s for me. Not even if I scan for them. I can manually create a connection but that doesn’t work.

linux-55zh:~ # iwlist scan
lo Interface doesn’t support scanning.

eth0 Interface doesn’t support scanning.

DaaX · March 6, 2011, 4:05am

hummm…

And what give in root :

iwconfig

Sorry, no german for me…

Raphleon_Donangelo · March 6, 2011, 4:08am

iwconfig
lo no wireless extensions.

eth0 no wireless extensions.

That’s no problem, I just thought I offer the additional language option. Thank you for all your effort.

DaaX · March 6, 2011, 4:13am

Are you sure the wireless is turned on on the router ? It looks like your card have no association with the wireless device…

Raphleon_Donangelo · March 6, 2011, 4:15am

Yes it is all turned on. My wife is even connected to it right now on her windows machine. I double checked SSid, password, security type. Everything. it’s very confusing. This is the very first time for me that I had struggled so much with Linux. Windows 7 works just fine.

DaaX · March 6, 2011, 4:20am

Post the result please :

dmesg | grep firmware

Darn! The driver is loaded…

I don’t know… if you go in your admin config of your router, do you see the ip adress of another computer other than your wife’s win 7 ?

Raphleon_Donangelo · March 6, 2011, 4:56am

Nope. I know it is very confusing and I have absolutely nothing left I can come up with. In either case, thank you for all the effort you put into this already.

DaaX · March 6, 2011, 4:58am

Sorry,

I’ll let experts pronounce themselves on this one. It is out of my expertise now… there are some better than me in this area.

Good luck.

Raphleon_Donangelo · March 6, 2011, 4:59am

Thank you for all your help. Well you heard it folks, anyone has some more suggestions?

Raphleon_Donangelo · March 7, 2011, 6:43pm

bump Anyone has any suggestions?

Raphleon_Donangelo · March 9, 2011, 3:26pm

bump again

I checked now on multiple locations and nothing. I tried on Wep, on Wpa/Wpa2 and even on unprotected connections and nothing happens. It just seems to not be able to connect to anything although all the settings are correct. I would love to be able to replace my windows partitions with a Linux distro but without my wireless it is useless to me.
Any suggestions?

Raphleon_Donangelo · March 12, 2011, 4:59pm

Hmm, no suggestions anyone?

I upgraded to Opensuse 11.4, nothing changed. I tried with KDE, With Gnome, x32 Bits and x64 Bits, I used Yast to manually configure it and I tried Kde Network manager as well. Nothing changed.

I out of ideas what to do. I am willing to try anything at this point. if you think you need to remote desktop to see whats off. Feel free.
