Can't get wireless to work
Hi. I have a new laptop with an Intel Centrino Advanced-N 6235 - 802.11A/B/G/N Wireless LAN.
I installed Arch, and found it is automatically using the iwlagn module. I can't seem to get the wireless to actually work though.
When I try 'ip link set wlan0 up' or 'netcfg mynetwork' (see the file contents below)
I get the following and I'm not sure how to fix it:

Re: Can't get wireless to work
welcome to the forums, pacmon. Please use BBCode [ code ] tags when posting snippets. Please Edit your post and add them so that it makes it more readable. It also provides scrollers which prevents the thread from getting too long.
There's no such thing as a stupid question, but there sure are a lot of inquisitive idiots !

Re: Can't get wireless to work
Try to disable 11n feature and look if it helps a little:
modprobe -r iwlagn
modprobe iwlagn 11n_disable=1Offline

Re: Can't get wireless to work
Thanks for the reply. Unfortunately, I still get the same error.
I do have a couple other bits of info:
1. I know this wifi works because I've had it working with ubuntu 12.04 (what it came with) and linux mint 13 (worked immediately after system install)
2. There is an additional line of the error that I left off because I figured it was just the polite version or a side consequence of what it had just spewed, but I'll add it here just in case:
wpa_supplicant did not start, possible configuration errorLast edited by pacmon (2012-06-28 01:57:36)

Re: Can't get wireless to work
Update:
I updated my kernel to 3.4.4-2 and now my wireless device isn't even loading.
I get the following error:

I unpacked the it and placed the iwlwifi-6000g2b-6.ucode in /usr/lib/firmware (where other versions were available).
I did a modprobe -r iwlagn; modprobe iwlagn; and even rebooted, but it still won't recognize the file.

Re: Can't get wireless to work
What happens if you add the driver to your rc.conf?

Re: Can't get wireless to work
I tried adding it like so, but no luck. Still the same error about unable to find the ucode file.

Re: Can't get wireless to work
Isn't your driver iwlagn?

Re: Can't get wireless to work
It was, yes. I figured from the wiki bit that you linked to it was looking for something along the lines as what I tried.
I just tried MODULES=(iwlagn), but that didn't work either. Still the same error.

Re: Can't get wireless to work
So, you have the firmware:
firmware: iwlwifi-6000g2b-6.ucode
Which means the error message you pasted earlier
[ 2.630029] iwlwifi 0000:02:00.0: request for firmware file 'iwlwifi-6000g2b-6.ucode' failed.
indicates that something is b0rked in there. Have you removed the firmware you installed manually? Run lsmod to make sure you haven't got any conflicting modules loaded?

Re: Can't get wireless to work
Removing the iwlwifi-6000g2b-6.ucode file from /usr/lib/firmware had no effect.
I'm not sure how to tell if there's anything conflicting, but here's the output of lsmod.

Re: Can't get wireless to work
Well, your module is loaded, the firmware is present... I've got nothing else, sorry.
If you have a hardware switch, make sure it is toggled on. Other than that, good luck!

Re: Can't get wireless to work
Hmm. Darn. Well, thanks for trying. I guess I'll have to hope someone might have an idea why it won't load the ucode file.
Worst case - I guess I can't put arch on this laptop.

Re: Can't get wireless to work
I had once a similiar problem after i compiled the wifi driver into the kernel. The problem is that at the time were the driver tries to load the firmware when the filesystem is not ready yet. You have to make sure the filesystem will function correct, before the driver wants to load the microcode.
I hope this helps

Re: Can't get wireless to work
From the wiki page, perhaps something in this paragraph is relevant and/or something you could try:
The MS Windows NETw4x32 driver can be used with ndiswrapper as an alternative to the iwl3945 and ipw3945 drivers.
In some cases (specifically a Dell Latitude D620 with Arch 2008.06, though it could happen elsewhere), after installation you may have both iwl3945 and ipw3945 in your MODULES=() section of /etc/rc.conf. The card will not work with both modules loaded, so you will have to blacklist the ipw3945 module in /etc/modprobe.d/modprobe.conf and then reboot or remove the module manually before you can use your wireless card.
By default, iwl3945 is configured to only work with networks on channels 1-11. Higher frequency bands are not allowed in some parts of the world (e.g. the US). In the EU however, channels 12 and 13 are used quite commonly (and Japan allows for channel 14). To make iwl3945 scan for all channels, add options cfg80211 ieee80211_regdom=EU to /etc/modprobe.d/modprobe.conf. With iwlist f you can check which channels are allowed.

Re: Can't get wireless to work
@0x530302 Could you explain a little more about what you mean? Wouldn't the filesystem have to be functional long before it got to loading wireless drivers?
@MoonSwan I haven't tried using ndiswrapper instead - although this chip is a lot newer than the 3945 series, so it may not work, but it's worth trying.
As for the rest of it... my MODULES=() section is empty. I had tried manually specifying it there as jason suggested, but it didn't work (so I removed it again).
The next section is about frequencies issues and I'm not even there yet. With the latest kernel the device isn't even recognized.
Thank you both for the suggestions.

Re: Can't get wireless to work
Had the same problem, and found a barbarian wise workaround - which did the trick for me:
Just copied the firmware file from /usr/lib/firmware to /lib/firmware
I'm still quite new to arch, but for whatever reason udev finds it here.
Hope this helps!

Re: Can't get wireless to work
Hey,
I have a Intel WiFi 5300 and I was having the same problem with "no suitable firmware found!". I was able to get it working by following jimflim post. I added a /firmware folder to /lib, then "sudo cp /usr/lib/firmware/iwlwifi-* /lib/firmware/", "modprobe -r iwlagn", "modprobe iwlagn". At this point the wireless was working, but there is a larger issue that should be resolved.
The issue is that /lib needs to be changed from a folder to a symlink to /usr/lib. If you have a file or folder not owned by glibc in /lib, /lib won't become a symlink even though other updates have made it expected to be one. I unloaded iwlagn (modprobe -r iwlagn), removed the firmware folder I added to /lib, then followed the instructions at https://wiki.archlinux.org/index.php/De … iki:usrlib to update glibc. I needed to remove google-earth and ld-lsb, and then was able to run pacman -Su. Everything works now!
Dan

Re: Can't get wireless to work
I have the same card in my computer, Intel Centrino Advanced-N 6235, and it is supposed to use the iwlwifi module, not the iwlagn...

Re: Can't get wireless to work
Hey WonderWoofy, it looks like you're right. I think iwlagn was the old name for iwlwifi.
modinfo iwlagn and modinfo iwlwifi both show the same file name: /usr/lib/modules/3.5.3-1-ARCH/kernel/drivers/net/wireless/iwlwifi/iwlwifi.ko.gz
Also, my lspci -v shows:
0c:00.0 Network controller: Intel Corporation Ultimate N WiFi Link 5300
Subsystem: Intel Corporation Device 1121
Flags: bus master, fast devsel, latency 0, IRQ 46

Re: Can't get wireless to work
iwlagn is not the old name, but rather a different module/driver altogether. I would do an lsmod to see if you have any other iwl* modules that could be conflicting. If so blacklist those.
