[SOLVED]Arch not acknowledging wireless card.

Stromblad · 2011-08-13 02:34:27

So Im a returning user, feel like a total newb again.

I recently purchased an "Asus k53sv-xr1"

The wireless card inside is "Intel Centrino Wireless-N 100," I determined this by installing the proper driver in windows and checking the device manage (as asus could not answer my question as to the model number and the spec indicate "integrated blahblahblah"

Following the "Wireless Setup Instructions" I did the following (filling the xs' with their respective version numbers)

___________________________________________________________________________
"Installing Firmware (Microcode)

Important: Installing these firmware packages is not required since the 2.6.34 kernel update, when the firmware files were moved to the linux-firmware package.

If you need wireless connectivity to access pacman's repositories, the firmware files are also available direct from Intel. See this page, select and download the archive.
$ wget http://intellinuxwireless.org/iwlwifi/downloads/iwlwifi-XXXX-ucode-XXX.XX.X.XX.tgz"

After downloading, you must extract and copy the *.ucode file to the firmware directory, commonly /lib/firmware
# tar zxvf iwlwifi-XXXX-ucode-XXX.XX.X.XX.tgz
# cd iwlwifi-XXXX-ucode-XXX.XX.X.XX/
# cp iwlwifi-XXXX-X.ucode /lib/firmware/"
___________________________________________________________________________

The wireless setup manual goes on to say that
"If MOD_AUTOLOAD is set to yes in /etc/rc.conf (it is by default) that should be all that is required. Simply check for the presence of the drivers by running ip addr from a terminal. There should be a listing for wlan0."

My outputs are the following

lspci | grep -i net

eth0 no wireless extentions

Thank you in advance!

Update

I did modprobe iwlagn

and follwed up by

dmesg | grep -i wifi

iwlagn : Intel wireless wifi link agn driver for linux, in-tree

yet still nothing from iwconfig

dodo3773 · 2011-08-13 03:15:58

What shows up if you use "ifconfig -a"?

Stromblad · 2011-08-13 03:19:23

eth0 and loop,

after modprobing iwlagn

same

dodo3773 · 2011-08-13 03:32:11

Are you able to update? Do you have an ethernet connection right now? What kernel version are you using? Are you sure that the the toggle switch on the laptop for wifi is turned on (dumb question I know but that has gotten me before)?

Stromblad · 2011-08-13 03:34:57

The laptop has no physical switch for wifi being on or off, bios also no option (which is moot anyway since it works in windows)
I went downstairs and plugged in to physical connection and did a full system update "pacman -Syu" still nothing.
I checked modautoload, tried modprobing it in myself, nothing. Im stumped

Stromblad · 2011-08-13 03:41:05

and another update, evidently
dmesg | grep -i wifi

iwlagn : Intel wireless wifi link agn driver for linux, in-tree

is the result regardless of whether or not i execute modprobe iwlagn

So I suppose it does acknowledge it, yet cannot create a wlan0 for some reason

What about "dmesg | grep iw" or "dmesg | grep RF"?

Sometimes it is not a physical switch. It might be a FN+HotKey.

dmesg | grep iw

iwlagn: Intel Wireless Wifi Link AGN driver for linux, in-tree:
iwlagn: Copyright(c) 2003-2010 Intel Corporation

dmesg | grep RF

would take me a very long time to type out.

but its just a bunch of REISERFS...BLAHBLAHBLAH
mostly to do with journaling, formats and filesystem type information
is that relevant?

I saw a post from a while back that had "RF_KILL" in the output. Was hoping maybe that was your problem as well. Try that instead.

Stromblad · 2011-08-13 03:59:55

try rf_kill?

No I meant in the search "dmesg | grep RF_KILL". Check out your F keys F1 F2 etc.. Are you sure there is not an image on one of them that looks like a wifi signal? Like "FN+F2" or something?

Stromblad · 2011-08-13 04:10:46

oh yea, i tried pressing the fn f2 but either way iwconfig reports the same. Im not really sure whats going on here

After pressing it did you try rebooting / reloading the modules etc..

Stromblad · 2011-08-13 04:21:03

no i did not, however i will

Stromblad · 2011-08-13 04:24:40

I did it twice, same result each time, iwconfig reports no wlan at all.

I dont know if this matters but i failed to mention it, "Starting Nework" always fails when I boot

The starting network failure might have something to do with your rc.conf. It seems like you should at least be able to find your interface though.

.:B:. · 2011-08-13 04:45:23

Try this:

# update-pciids

Then check lspci output again.

Stromblad · 2011-08-16 00:23:44

If anything I have (re)learned some things about whats going on, which...ultimately led to more questions.

First these two snippets led me to some interesting ideas.

"Installing Firmware (Microcode)

Important: Installing these firmware packages is not required since the 2.6.34 kernel update, when the firmware files were moved to the linux-firmware package.

If you need wireless connectivity to access pacman's repositories, the firmware files are also available direct from Intel. See this page, select and download the archive."

From the "Wireless Setup" Wiki

and
"Using kernels 2.6.24 and up
These kernels have the iwlwifi driver included and the released drivers (available from this site under download page) do not work with these kernels. If you want to run the latest (or very close to it) development code with your kernel then you should use the compat-wireless project that retrieves the latest driver development code from the upstream repository. We do push our changes to this repository very frequently."

Which means that the firmware I downladed from http://intellinuxwireless.org/?p=iwlwifi, would not work.
I reinstalled, this time including the all the "iwl" packages from the "dev" section of the packages.

The result was the same.

dmesg | grep -i iw
would report nothing at all

until i input the command

modprobe iwlagn

then dmesg | grep -i iw would report
iwlagn: Intel(r) Wireless WiFi Link AGN driver for linux, 2.6.33-ARCH-ks
iwlagn: Copyright(c) 2003-2009 Intel Corporation

I really wanted to figure this out the arch way, but I can find little to no threads on my specific card.."Intel Centrino N-100 Wireless"
If anyone can help, it would be greatly appreciated. In the meantime, I will boot the ubuntu live cd and hope that wireless is automatically configured, that way I can at the very least, attempt to figure out what model card it reports and try again with that information.

My question, other than "can anyone provide some insight as to why the system can detect the card, but not be able to bring wlan0 up", is can modprobe insert modules that do not correspond with what is actually in the machine?

Thank you

Gusar · 2011-08-16 00:49:40

We need the output of 'lscpi -nn', so we'll know the pci-id of the card. But basically, an up-to-date kernel with an up-to-date linux-firmware package, and the thing should work out of the box. So, which kernel and linux-firmware package are you using?

Stromblad · 2011-08-16 01:02:46

Ill do the bes ti can, forgive my ignorance as im remembering commands as i go along.
