[SOLVED] can't find wireless interface on Samsung 700G7C

[jody]

Hi

I have just installed a basic working gentoo on my Samsung 700G7C,
and went on to install wpa_supplicant following the handbook
http://www.gentoo.org/doc/en/handbook/handbook-x86.xml?part=4&chap=4
My configuration file:

[BillWho]

jody,

Did you compile the correct modules for your interface

If you did, are they loading

Do you have the wlan0 symlinked to net.lo and added to the default renlevel

Did you make the entries to /etc/conf.d/net

Hi BillWho

Thank You for your reply.

Thanks for your help.
With 'emerge --search iwl' i found a lot of iwl ucode, but not exactly the one i was looking for (iwlwifi-6000g2b).
Some googling brought me to the page http://intellinuxwireless.org/?n=downloads
where i found that the code i was looking for is hiding behind the name iwl6030.
After emerging net-wireless/iwl6030-ucode and rebooting my machine,
i am now able to see the wireless interface with iwconfig:

Hi
There still seems to be a problem with the firmware (i guess)...
The loading of the module seems to work, but when i start wpa_supplicant, this fails,
and a look into dmesg shows some error messages(Microcode SW error detected):

jody,

Try kicking it off with

Hi BillWho

Sorry for the delay in answering.

I tried the command you suggested; it gives some verbose output, but seems to die at the same position:

[jody]

It looks like this problem with iwlwifi has been known for months:
https://bugzilla.kernel.org/show_bug.cgi?id=42890
The error described there is not exactly the same but the dump
shown in dmesg looks very similar tio what i get.

So i guess i'll have to wait with WIFI until a fixed kernel appears...

Did you try the mentioned workaround?

options iwlwifi 11n_disable=1 # for modprobe.conf

or

iwlwifi.11n_disable=1 # for grub.conf grub.cfg or lilo.conf

Thank You for your suggestion.

In my grub conf i have now this:

Both variants achieve the same result, so don't worry about that.

Reading again, it seems that a rather recent kernel is used (3.4-rc7). With that bootparameter, it should 'hide' the problem. However, I did notice a lot of work in the iwlwifi driver in the main git kernel and wireless-testing tree's.

First, another less intrusive suggestion:

Hi rexilion

The unintrusive method worked!
The version of iwlwifi ther is 18.168.6.1 instead of 17.168.5.2.

Now i am able to start wlan0, and it also gets an IP address from dhcp:

Good to hear! If you ever feel adventurous, start playing with git, I can recommend that

I have still errors even with the wireless testing kernel....

I don't know really what the hell to do...

Sorry, I thought the the thread was about the card (Intel 7260) and not about a specific model.

I opened another thread but I could not find any help... so I wanted to understand if the solution found in this thread was applicable also to my case, given that the card is the same.
