After I updated my 9.10 laptop this morning, no wireless interfaces show up. Ifconfig / iwconfig show only my lo and eth0 interfaces, but not my ath0 interface. I can get online if i use my ethernet jack, but just no wireless. I had madwifi running on my atheros chipset. Could the update have broken that and I have to reinstall the madwifi drivers?

Asus eee 900ha Ubuntu 9.10
2.6.31-17-generic kernel

UPDATE:

At Grub, I have the choice of booting into the 2.6.31-17, -16, -15, or -14 kernel. When I boot into the -16 kernel, the wifi works fine. I tried booting into back into the -17 kernel and it just doesn't work there. I've tried disabling, then enabling the wireless in bios, but that hasn't worked either.

Good evening, I am having the same problem. I have a Dell laptop with the 3945ABG chipset. The wireless was showing as disabled when using 'lshw -C network', although there were no errors in the normal places (dmesg etc) Going back to -15 fixed the problem. Looks like there is a problem with the upgrade to -17? Linux ubuntu 2.6.28-15-generic #52-Ubuntu SMP Wed Sep 9 10:48:52 UTC 2009 x86_64 GNU/Linux

To add more colour to my problem. Its actually2.6.31-17 that I'm having a problem with, where the wireless is working with 2.6.28-15. Although annoyingly in the older version sound or the laptop build in mouse pad are not working. Sigh.

Anyway, here is the output of various commands for both the working and nonworking configurations. Hope it helps!

Comparing the two output from dmesg, looks like there is a problem in the startup, as this line is missing from the non working output...

Similar problem on my Dell Inspiron 500m

Booting with kernel 2.6.31-15 works OK, but with 2.6.31-16 WiFi only comes up 1 in 5 boots/restarts.

I just updated to 2.6.31-17 as the bug fix list mentioned iwlwifi several times, but it looks like this is just as bad. Its probably a timing issue.

Please check if you have all the correct kernel packages installed, eg linux-headers-generic and/or -backports etc. It sounds like that, had the same myself.

January 9th, 2010, 03:11 PM
Thank you for your reply, though what would be the correct packages? I installed the wireless backports package, but simply installing had no effect. Is there configuration involved? Or do I need to downgrade the install and then re-upgrade?

I wondered if I was missing something obvious. Now, after reading this thread, I see that I wasn't. Reverting from the -17 kernel to the -16 kernel caused the wireless to come right back up.

I'm eagerly awaiting a simple fix for this, perhaps loading some kernel module. I suppose that eventually the kernel itself will get fixed.

Hi everybody

The madwifi drivers has to be recompiled after every major updates namely the kernel updated. So it can be solved by recompiling the madwifi. No need to install it again.

Dr KurianI don't believe the madwifi module has any effect on the original poster's Intel 3945ABG.

Assuming you have linux-image-generic installed (the kernel meta package) you need linux-headers-generic to be installed as well (the meta package of the linux kernel header). If both are installed everything should be working.

I can test if I have the same problem as you (same network card), but need to boot to Ubuntu and downgrade the kernel.

Could you post the output from:

dpkg -l | grep linux-

Much appreciated.

Just a note, I've installed the backport on the advice from someone on this thread, however I have not done anything to configure them...

Alrighty, then 3945ABG fans! Let's hunker down and solve this thing! First, is your wireless card activated but just not connecting? Please do:
iwconfigDo you see an interface wlan0, perhaps? If so, what happens, or doesn't happen, when you click the Network Manager icon and try to connect? Do you see your network? Does it ask for encryption details, WEP, WPA, etc.?

If you have no interface, let's load the module and check again:
sudo modprobe iwl3945
iwconfigNow is the interface present? Can you click and connect?

If you still have no joy, let's see what the kernel has to report:
sudo cat /var/log/messages | grep iwl

Madwifi has absolutely nothing to do with 3945ABG, so forget that. Also, Network Manager will not allow a wireless connection if you are connected wired, so disconnect the wire and reboot before you try the wireless.

FWIW, I am replying with a 3945ABG and the latest kernel. It works fine.

Hi chili555, I have different hardware but a similar problem.

Following your ideas:-
With kernel...-17 iwconfig shows my wifi interface. This is sometimes "eth0", sometimes "eth0_rename", but left-clicking on the network icon does not list any access points.
With both kernel...15 (wifi OK) and kernel...17 I get the same info in the messages log:-

Any suggestions?

Another one with the same trouble. Acer 5534, Atheros chipset. Using the latest compat-wireless driver. Worked fine before update. Recompiling didn't fix.

Would really like to see a fix!

@Statik-

Please start a new thread referencing your Atheros whatever. Also tell us if you looked for a later version of compat-wireless and if you included make clean in the recompile. Thanks.

Chili555, thanks for your help. iwconfig looks like the following

Doing the modprode iwl3945 had no effect. The interface is there, but is disabled. The wireless icon at the top reports this, as does lshw -C network.

Very mysterious! Please open a terminal and do:
sudo tail -f /var/log/messagesThen open another terminal and do:
sudo rmmod -f iwl3945
sudo modprobe iwl3945 fw_restart3945=1Now, in the messages terminal, does the firmware get reloaded and all the iwl-phy0s come to life?

When your wireless is disabled, i.e. in 2.6.31-17, do the Fn keys have any effect? On my laptop, wireless and bluetooth are enabled and disabled with Fn+F4. You should be able to see activity in messages.

The system picked up the activated iwl3945 driver, but its still disabled. (The desktop displayed the new wireless connection but said disabled.)

The laptop doesnt have anything like that on the keyboard, (its a Dell XPS M1330 if you know the machine.) there is however a kill switch, which is definitely off as Im posting this from the laptop, albeit on a older version. (The sound and other things dont work on this version, which is why I'd like the latest one to work!)

Appologies. The sound doesnt work on the old version however the wireless drivers do. On ubuntu 2.6.28-15-generic the sound works, its just the wireless that doesn't.

Appologies. The sound doesnt work on the old version however the wireless drivers do. On ubuntu 2.6.28-15-generic the sound works, its just the wireless that doesn't.No problem. It just makes me think that the computer's BIOS and the ACPI system in the operating system are not working and playing well together. dmesg will probably give us some more clues.

Please reboot and confirm that, in the computer's BIOS, under PCI, that IRQs are all marked 'Auto Detect.' Also, please open Synaptic and confirm that you have installed libsmbios2 and linux-backports-modules-karmic-generic. Please install if not. Please post:

Unfortunately my BIOS does not seem to have any options for the PCI, it would seem Dell like to lock down the machines they make...

I did not have that backports package installed. I have now installed it, does it require configuration?

Output from rfkill is below, Im guessing hard blocked means it thinks the kill switch is active (would also disable the driver on lshw?) However I assure you this is not the case, as I am posting this from the laptop!!



0: dell-wifi: Wireless LAN

Im guessing hard blocked means it thinks the kill switch is activeYes, indeed! Please do:

If so, we can blacklist dell_laptop. If not, I can keep trying.

Ah-hah! That did indeed solve the problem, as soon as I ran the rmmod the wireless was detected! Awesome thank you very much. Is it worth dropping this as a sticky as Im sure there are a lot of Dell users suffering?

I hope they will find it by the search function. You might just mark the thread 'Solved.'

To make this permanent, edit /etc/modprobe.d/blacklist.conf and add dell_laptop.

Hi Everybody
Please visit my thread to recompile the drivers
http://ubuntuforums.org/showthread.php?t=1309072

This fix may not solve everyone's problems, but it certainly solved mine. Thanks and kudos to Dr. Kurian.

Incidentally, the latest Kubuntu upgrade, which included a kernel upgrade, also fixed the problems with my microphone not working with Skype. Very nice when a problem just goes away.

Even though I am the original poster of this thread, I haven't been able to get any help since the thread was hijacked by someone with a similar, but fundamentally different problem. Many people are saying that they have wireless interfaces, but just cannot connect to a network. I have no wireless interfaces. When I run iwconfig or ifconfig, all I get is eth0 and lo for interfaces. I wouldn't think this would be solved by simply recompiling my madwifi drivers since before I installed madwifi originally, my wifi was working, just with different drivers. I really don't know what to do since I don't have any interfaces at all. Any ideas? Thanks

Boy, it got hijacked big time and I was not as careful as I wished. Let's start from scratch and I promise I will eject the hijackers immediately.

Please post:
sudo lshw -c network

@chili555 -- please help me!

I found this thread and followed the advice you gave as I have the exact same problem as the poster. Long story short I executed the command you posted


sudo rmmod -f dell_laptop

Only for me it didn't solve the problem, it made it worse, now I have no wireless in either kernel. Please can you let me know how to undo this command???

A while back I was running the -17 kernel and encountered the no-wireless problem. I took Dr. Kurian's suggestion and my wireless problem was solved. But now, after the -17 to-19 update, it's returned. And, as before, reverting to the previous kernel (now -17) solved it.

Is there no end to this? Is there some way to immunize the wireless facility against kernel updates? Having to dance this quadrille on every kernel update is a pain in the butt.

Added note: I recompiled the madwifi drivers according to Dr. Kurian's instructions and got the -19 kernel working also. I also had to dump pulse-audio (in favor of xine) to get sound working again.

I had to recompile the compatwireless drivers after the last kernel update which made wireless work great again.

Some info on how to do the recompilation and integrate the result into the running kernel would be much appreciated.

Hello, i'm sorry for my ignorance, but i am a newborn to linux. i am also using a dell laptop with a 3945ABG chipset wireless card. despite the help provided for others, i am having the same problem as lietopurify. it's not that i just can't connect, it's that i have no interface. i am using a much older version of ubuntu aswell, 6. something i don't remember off the top of my head.

I would give all the specs i could but i have no hard wire connection and am working with a spotty connection from a neighbor, as well i'm running winxp also. i have tried mostly everything posted in this thread. jotting them down on paper and switching over but to no avail.

I have no intentions on jacking this thread, again, mind you; but i've always wanted to learn linux, and frankly this is turning me off to it.

So, has anyone made any progress with this?
Help would be so greatly appreciated.
Or a point in the right direction of an open system that actually works.

Thanks.
