Centrino N-1000 Wireless chip not connecting with encryption

English Network/Internet
#1

Have been unable to use Wi-Fi except on an unencrypted AP. This is not acceptable, but I can’t get the Centrino Wireless-N 1000 (called “Link 100” in some places) in my Toshiba Satellite to connect with encryption. The Intel project for Linux Wi-Fi drivers says of the driver recommended for this chip “**The iwlwifi driver has been merged into mainline kernel…” ** The driver that seems to be installed is iwlagn.

Checking further to see if the kernel module iwlagn actually is installed:

modprobe -c | grep iwlagn

options iwlagn 11n_disable=0
options iwlagn 11n_disable=1

< snip >

Looks like the last option disables this driver and then it is named as an alias for iwl4965. (Is that right? The man page for modprobe doesn’t mention alias.) Can I tell from this list (shortened by snipping more alias statements of the same form) which driver is functioning for Wi-Fi? The iwlagn driver was the default for this 32-bit openSuse 11.4, but that driver name no longer appears in the Yast page for wireless configuration (network/network devices) where the driver is said to be r8169.

In directory /lib/modules/2.6.37.6-0.11-default/kernel/drivers/net/wireless/iwlwifi there are three modules: iwl3945.ko, iwlagn.ko, and iwlcore.ko. But the driver recommended for my chip is iwlwifi. How can I use it rather than the drivers that don’t seem to be working? And how did r8169 get configured? This driver occupies many directories under /sys/bus/pci/drivers/r8169.

I’ve followed the directions in the sticky posting in this forum. But I have not seen how to control the Wi-Fi driver so I could try the one Intel recommends for this chip. Suggestions would be most welcome.

Nearly all the instructions given in the Forum say that you should mention the
version of openSUSE that you are using. Congratulations - you nearly avoided
complying with that directive. Only the kernel version of 2.6.37 gave you away.
That kernel means 11.4. :slight_smile: The Intel wireless drivers have changed and improved
a lot, which is part of the reason that your system does not conform to what you
read on the Internet.

Any problems that we would find and fix with the 2.6.37 kernel, which is 7
generations old, are likely to have already been fixed. I suggest that you add
the wireless repo for 11.4 and install the compat-wireless package for your
kernel. That will get you modern drivers, and I expect that your problems will
disappear.

Thanks for directing me to the wireless repo. Added it, updated, cycled the machine off and on. modprobe now tells me

In linux 3.2 driver “iwlagn.ko” was renamed to “iwlwifi.ko”

My reading of this makes iwlwifi the current driver, deprecating iwlagn.
However, modprobe also shows the driver is now iwlcore.ko, not iwlwifi.ko or iwlagn.ko.
A file search shows that iwlagn still exists, but with a newer date of Jan 2012. Iwlwifi has been added to my machine, with microcode (a dash 3 version) for the Centrino Wireless-N 1000 chip. Will a later version of microcode be installed and used automatically?
However, after one power cycle, neither kNetwork Manager nor Yast/Network Devices/Network Settings report that wlan0 exists. Obviously I’m missing something. Pointers appreciated.

(PS: the version of openSuse was not in the body but in the signature)

I never read signatures. Never assume that anyone else will.

What does ‘lsmod | grep iwl’ show? With a name change in compat-wireless, you
may need to blacklist the old versions.

You should also post the output of ‘/sbin/lspci -nn’ for your wireless card.
That info will tell what the correct driver is named.

I see the wlan hardware, but no mention of a driver. None installed? Modprobe confuses me by showing names of two wlan drivers:

Yast Network Settings and Network Manager show no wireless card/interface. Clicking on “Add” in Yast produces a dialog page on which the pull down menu for “Module” is blank. This Toshiba has a touch-button on the keyboard to toggle wlan0 on/off–it is on. In Network Manager the “scan” option shows no interface and no AP’s.

I’d like to stay with openSuse 11.4 until 12.2 comes out, but it’s looking like this install is too messed up to bother with fixing. I hope that’s not right and there’s a simple fix (well, as simple as Linux allows :-).

That is not a correct usage of grep. It searches for the EXACT string you
enter. It does not use wild cards. No driver will be named iwl*.

You don’t see anything because you do not have a driver loaded. Why I don’t
know. Are you certain that you installed the compat-wireless package for your
kernel? I don’t see any evidence that you did.

Does the output of the dmesg command show anything of interest? DO NOT POST all
of it. It is too big, and most is not of interest.

#7

dmesg | grep driver
mentions nothing related to wireless.
Substituting ‘wireless’ or ‘802’ or ‘1000’ in the grep command produces no output. Looks like the driver module isn’t installed.

YOU need to read the output. Grepping for arbitrary words is not going to be
very fruitful.

#9

Reading the output of lsmod shows nothing that appears related to wireless or WiFi–apparently no module installed.

Have tried to load iwlwifi manually, but modprobe reports an error: module not found. Used the module name both with and without the .ko extension. Searched for *.ko files to identify their directories, then copied iwlwifi into many of them, for example /lib/modules/2.6.37.6-0.20-default/kernel/net/wireless/ (which is the latest update of the kernel for 11.4 that I see in the On Line Update of Yast). Changed the working directory to one containing a copy of iwlwifi.ko; modprobe still couldn’t find it. Used the full path as in modprobe /lib/modules/2.6.37.6-0.20-default/kernel/net/wireless/iwlwifi (where it is visible in Dolphin)–modprobe still can’t find it.
Read up on modprobe usage, but learned nothing that helped. Working in a terminal with SU=root privileges. Network Manager is running, visible in the system tray. NM says the wireless device (with the MAC address displayed) is disconnected. Have tried configuring in Yast, with ifup–same result.
I must be missing a detail in using modprobe. Would appreciate a pointer to my error(s).
Thanks

For the record, you should not copy modules willy-nilly into multiple
directories. The kernel will have it in the correct place. If it does not load,
then something else is wrong. If your system has created a wlan0 device, then
the driver is loaded.

First of all, please post the output of the following (inside code tags the way
I am doing):

This one is your wireless device, and 8086:0083 is definitely in the tables for
iwlwifi. The driver uses a subvendor code, but I have not yet determined if it
uses that to include/exclude devices.

This output confirms that iwlwifi is available as a module.

After a fresh reboot, please run the following commands and post the results:


/sbin/lspci -nnv | grep -A4 0083
lsmod | grep iwlwifi
sudo /sbin/modprobe -v iwlwifi

The first of those will report the subvendor code for your device, the second
will reverify that iwlwifi is not loaded, and the third shows you the correct
syntax for loading it.

In the meantime, I will look at the driver source to see what it does with that
subvendor info.

Please remove all but the first 3 lines of this file. First of all, modprobe
does not use any extension. Once you added line 4, the rest of the file is
ignored. Secondly, the device will be loaded from its PCI ID, and a modprobe
will not be needed for it. BTW, the subvendor ID (the 1305 part of the lspci
output) is one that is allowed. Once you have fixed 99-local.conf, the driver
should load.

#16

But the driver didn’t load. Booted a live CD (11.4, same as installed) to see if a driver would load. It did: iwlagn, the original module with the original problems. That is, the config screens won’t accept the WPA password (PSK, managed) installed in the 802.11n router. What’s so frustrating is that a new iPad accepted the same p/w and connected without a problem.
I’d re-install 11.4 but would face the same need to install the iwlwifi module, which I have not been able to do. Is there a way to swap modules after a clean install? What’s the outlook for wireless in 12.2? Maybe I should wait until Sept :frowning:

Release 11.4 has a bug that was introduced with RC2 and not fixed until after
the release. This bug prevented WPA/WPA2 connections. As openSUSE NEVER
remasters the distribution media, that is the reason the 11.4 Live CD does not
work for you. Any 11.4 system needs to be updated. Have you done that?

Have you fixed the problem that is in 99-local.conf? If not, do so now and
reboot. Then rerun the following commands


lsmod | grep iwlwifi
sudo /sbin/modprobe -v iwlwifi

Please show everything from the prompt and command at the beginning, and the
prompt after the command completes.

Modules must be built using the exact kernel headers and the compiler used to
build the kernel. Do you think modules can be swapped? The answer is from one
openSUSE kernel to the same one. Even changing from 3.1.10-2 to 3.1.10-3 would
fail!!

If you want the latest set of modules for your kernel, you should install the
compat-wireless package for your kernel.

#18

Edited 99-local.conf and rebooted. (replaced the host name with yyyy)


yyyy:/home/konsultor # lsmod | grep iwlwifi                              #no result
yyyy:/home/konsultor # /sbin/modprobe -v iwlwifi
FATAL: Module iwlwifi not found.
yyyy:/home/konsultor #

Yes, have done all the on-line updates and activated the wireless repository for 11.4. Checking again for compat-wireless, I see that I installed compat-wireless-scripts and c-w-kmp-default, but there are three other packages: c-w-kmp-desktop, c-w-kmp-pae, and c-w-kmp-xen which are not installed. I’ve assumed the package names containing “compat” but not “wireless” are irrelevant.

Your message is the first I’ve heard that 11.4 as distributed has a bug in WPA. No searches of the forums revealed anything like that. So, if the updates have corrected the problem, it seems some other error entered my copy of 11.4 (I do have fat fingers sometimes). If all that is accurate, then the best move for me might be a fresh install of 11.4 followed by an on-line update. That’s not too hard as /home is in a separate partition and I have backups on a server. However, I believe I tried that some time ago (last year?) What do you think?
Thanks.

You need the c-w-kmp that exactly matches your kernel. If you are using the
“default” kernel, then you have the correct version.

That issue was widely discussed at the time, but the search mechanism on the
forums is not the best.

If you are doing a fresh install, then switch to 12.1. The wireless stuff was
improved a lot.

Rejoice in 12.2! This version of openSuse turns up not only the on-board 802.11 chip but also a USB-attached AUStech device.
Thank you, developers.
