View Full Version : [ubuntu] No Wireless Connection anymore

Hi,

I am running Ubuntu 8.04 on a Dell Inspiron 6400 laptop and up until a day or so ago the wireless connection was working just fine. I always let the system download updates and I think the kernel is now showing version -19. But my wireless connection has suddenly stopped working. I've done a clean re-install of 8.04 and let the system download any updates but haven't added any new programs. It wanted to download a driver for the wireless card (which it did last time) so I let it do this. However all I get when I click the network icon are the options

Wired Network (currently checked)
Wireless Networks (unable to select this)
Connect to other Wireless Network...
Create New Wireless Network...
Connect to 802.1x Protected Wired Network..
Manual Configuration...

I don't get any network bars in the top panel as I used to and if I try
Connect to other Wireless Network...
and enter my NetworkName and WEP key then it thinks for a minute or so and keeps asking for the same information.

Any help greatfully received as I'm completely stuck here. I can't understand how something so easy to set up before is now broken.

Yes, please, please. Anyone? I'm having the same problem and can't seem to find an answer anywhere. New Ubuntu user, loving it and it worked perfectly upon installation, then magically started exhibiting the same behavior mentioned above.

It's worth noting that I can maintain a connection to an unsecured network without problem; the issue seems to be specific to WEP. Carl, is this true for you, too?

I'm using a Dell Inspiron 8600 and Hardy Heron. Hope you don't mind me doubling your question....I've only found this issue in one other spot (on Launchpad) and the thread was closed since no one answered. This really is the one stumbling block that keeps me from dumping XP entirely.

Fingers crossed....

I have asked the mods to put up a "sticky" warning Ubuntu users of this problem of doing updates and possibly losing funtions.


I had the same problem with losing wireless after the updates. I re did the commands that I used - to install wireless in the first place and it worked.

My concern is not so much just replacing wireless with some commands...it can be done. There are many helpful and fine people on this forum ready to help.

But my main concern if someone installed Ubuntu for a new user on a laptop and the new user thinking they did the right thing and did the updates and lost functions....it doesn't make for a good first impression.

Not only that, but this is something the Linux critics will instantly latch upon. Frankly I am tired (as others are) of hearing that "Linux is not ready for desktop" mantra over and over again. It is ready for desktop, but some glitches need to be worked out and new users should be at least be given a fair warning.

Especially after someone who has been using Windows for a long time and downloading updates and never lost functions.

If I come across of being critical, thats not my intention. I just think the update situation needs to be addressed.

Hi,

Just back from a meeting with friends. I mentioned this problem, and a friend did a (wireless!) update to test if this was indeed the problem. The moment the update was finished, he lost his wireless.
So now he's mad at me for suggesting the test ;-).
This is very bad. Updates are supposed to update your machine, not downgrade! Please fix this ASAP!

June 27th, 2008, 11:05 PM
Thank you....I couldn't agree more - now that I know it was an update I've done a little more searching and see this is certainly widespread!

So it sounds like a clean install will fix the problem....But (please pardon the newbie question...) any idea which updates are the problem? Is it all of them? Or is there a specific type of update we should ignore?

Thanks very much.

You have a different wireless card to me, so there isn't much I can do. Try
sudo modprobe ath_pci
sudo modprobe wlan_scan_sta

Then reboot. I'm not sure what else to do, best wait for someone to come along who has installed its drivers themselves. Also, what kernel are you running (uname -r)

801
June 28th, 2008, 12:39 AM
@Entropy:
kernel 2.6.22-15-generic
which is weird, I remember updating to ....19. I'll dig into grub to see what's happening there.

Both ath_pci and wlan_scan_sta modprobe give:
FATAL: Module (...) not found.

Thanks anyway, I'll be back to tell what grub gives.

801
June 28th, 2008, 12:51 AM
Hmmmm.... kernel (...)19 is on my Kubuntu laptop. The machine with the wifi problems (an EEEpc with Xubuntu) is indeed running kernel (...)15.
Should I do an upgrade to Xubuntu 8.04 LTS? Need to be sure on this, I'll better wait what happens to/with the other posters or updates, since the problem doesn't seem to be related to any single platform.
Nevertheless, thank you for trying!

June 28th, 2008, 01:11 AM
The kernel 2.6.22 is about a year old, rather than the current 2.6.24-19 release. Upgrading would probably solve the problem, assuming that there is nothing keeping you using the old version. Can you do
ls /lib/modules/2.6.22-15-generic
ls /lib/modules/2.6.22-15-generic/madwifi to determine if you have the drivers installed (which ship with newer kernels). This stopped working when you tried to update, correct? strange...

801
June 28th, 2008, 01:33 AM
@Entropy:
Ouch. I hadn't even noticed I was on 22 instead of 24. Good for you.

No madwifi directory in /lib(etc), so there's no point in posting the output of both ls.

Is anybody else with this problem on kernel ...22 like me? CarlWalters? qlucy? Because if they are, it seems like we tackled the problem.
I'll wait with upgrading until we know for sure.

@Entropy: yes, but the problem occurred not when I tried to update, but when the update succeeded. Small but significant difference ;-).

I am getting this same problem on a Inspiron 6000. One day, after some updates, my wirless went away. I tried a fresh install and now it will simply not work period. I have my restricted drivers enabled and still nothing.

Can anyone else who can't get their wireless to work after the updates post the results of
uname -r
lspci
ls /lib/modules

and make sure you haven't accidentially hit the wireless kill switch (fn + F2 on inspirons), ive spent hours trying to find out why wireless had stopped working just to press 2 buttons and get it back :lol:

@801

Could you do ls /lib/modules too. I want to see what kernel you were running before this. And, what version of (x)ubuntu are you running? I cant see why you would get downgraded (I dont even know if that is possible).

If you need wireless in the meantime you can install the madwifi drivers yourself or upgrade the kernel by installing one of the linux-image packages from the repos

@Carl

Does it work when you try to connect to unsecure networks. I'm going to change my network to WEP to test myself when I can. Can you post
uname -r
lspci
iwconfig please?

@qlucy

Can you post

uname -r
lspci
iwconfig too? This started happening after a update, correct?

Similar issue here - still probs with WLAN - either no connection possible (autoatic connection) or - after creating it manually - it looses accidently the connection and cannot reconnect or, if connected, cannot go to internet or internal adresses.

Thats really annoying :-(

What I would like to try is to uninstall any! wlan settings and programs and reinstall them - how can I do this? Any help appreciated :-)

Thanks in advance!

the update to kernel 2.6.22-15 seems to be the problem luckily the option in grub bootloader lets me load kernel 2.6.22-14. but why.

801
June 28th, 2008, 02:15 PM
Indeed deleonjavier, it's a kernel-related problem. That friend of mine found out that if you load the previous kernel using grub everything is OK again. I tested it on my machine, and presto!

@ CarlWalters & Grone1985
It seems that everyone affected by this is either running broadcom or athros cards. Is wireless turned on (FN + F2)? Is the driver still showing in the restricted drivers dialog? Can you post the output of
lshw -C network please? Try the steps at http://ubuntuforums.org/showthread.php?t=684495 to connect to the network and post any errors


Thanks for bringing that to our attention. It's probably best to let them handle it.

Wireless is still turned on (at least the light is on on the laptop), not quite sure how to check the restricted drivers though. The ouput of lshw -C is



lshw -C network

It looks from this as though there is no driver installed for the wireless interface. Although when I go to System->Administration->Hardware Drivers it shows "Broadcom B43 Wireless Driver" enabled and in use (although the box also says "No proprietary drivers are in use on this system"

If I try the instructions at http://ubuntuforums.org/showthread.php?t=684495 substituting wlan0 for <network> (not certain if this is correct?) then I get

Because of what qlucy said about being able to connect to unsecured networks I think its more of a wep issue. A bit of searching has brought up http://ubuntuforums.org/showthread.php?t=197102&highlight=broadcom+4318+ndiswrapper (https://bugs.launchpad.net/ubuntu/+source/knetworkmanager/+bug/139812). Can you do the quoted part and retry connecting. I'm pretty sure that your drivers are all working fine.

EDIT: Yes, wlan0 is correct.

I love Ubuntu don't get me wrong, but I to have been frustrated with updates breaking things.

A kernel update should come with a caveat, or the ability to specifically not do kernel updates would be fine (if we can already do that I haven't figured out how yet)

Regression testing is a must, especially where internet connections are concerned. The only good reason I can think of for not regression testing would be in the rare case where there is a security flaw that outweighs the endusers need to have a pain free wifi experience (yeah I'd rather fight with ndis wrapper than my credit card company, suddenly dealing with stubborn hardware seems easy when in that context no?)

Anyway. Keep up the good work Canonical, but slow down, enjoy the ride, if its not an urgent security update, then please take your time.

no go I'm afraid. I tried



sudoedit /etc/network/interfaces
add the line
iface wlan0 inet dhcp


(I'm glad I could remember a few vi commands from years ago :) )

and then



carl@carl-laptop:~$ sudo iwconfig wlan0 essid CarlWilliamWalters key 01234567890123456789ABCDEF sudo ifup wlan0
iwconfig: unknown command "sudo"

so I tried splitting the line in two

carl@carl-laptop:~$ sudo iwconfig wlan0 essid CarlWilliamWalters key 01234567890123456789ABCDEF
carl@carl-laptop:~$ sudo ifup wlan0
Ignoring unknown interface wlan0=wlan0.


so I'm still confused...

I think editing /etc/network/interfaces did it, but I should have told you to do sudo /etc/init.d/networking restart, which would have been done when you rebooted (maybe when you fn + F2 too? nothing has changed from what you posted anyway). Anyway, good to know what the problem is.

Thank you all so much for your help! Entropy, thank you especially, and I apologize for disappearing; I was away from my computer for a few days.

After reading all the posts I ran:
lshw -C network

the end said wireless=unassociated

tried Fn + F2, then lshw -C network again

this time it said wireless=disabled

did Fn + F2 to turn it back on, did the same thing and got wireless=unassociated again.

rebooted.

lshw -C network

now it says wireless=IEEE 802.11g

yay!!!

so far, so good...I've been online for awhile now and it's still connected. If it acts up again, I'll be sure to try the other fix, but it seems like it just needed to reinitialize and turning it off and on did it. I'm a bit surprised by this since I one of the first things tried was right-clicking on the wireless icon and disabling then enabling it, then rebooting....but I'll take it.

thank you again! this changes my world. :)
