3945ABG wireless card doesn't work with 8.04

[DO55]

In 7.10 the wireless card work ok with my lenovo n100 but the wireless card dose not work with cd live for ubuntu 8.04 (hardware wireless LED is off )

[GGS1988 (gunther-schrijvers)]

I have the same problem with this wireless card. I can see wireless networks but I can't connect to them. In 7.10 it did work but today I did a fresh install of 8.04 and it doesn't work anymore.

Same problem here.

It connects if I turn off security on rooter (WEP/WPA).

[Scott Dunbar (scott-xigole)]

The same issue occurs with a Dell Latitude D820. Worked perfectly in 7.10. No LED, no connection in 8.04.

[Wassermam (buchalla)]

Same problem here.
The live CD (Ubuntu 8.04) and the fresh install doesn't work.
My notebook is a Gigabyte 566U

[Davjack (david-davjack)]

I have the same problem (Ubuntu 8.04 on a Dell Inspiron 1720)

[caecus314 (caecus314)]

I have the same problem of seeing networks but not being able to connect to them in Kubuntu 8.04. I also installed Ubuntu 8.04, thinking it might be a problem with Knetworkmanager, but there was no difference. I am using a Lenovo T61p with an Intel 3945 wireless card.

I have the same problem with no LED and no network at all with my Lenovo C200 and 3945ABG wireless card, when I use the old kernel from Ubuntu 7.10 it works again, but with the new kernel it's dead...

[mkaatman (mkaatman)]

Fresh install of 8.04 on my dell d620 and I can see networks but it never connects.

In 7.10 it worked about 75% of the time.

I may confirm this bug on a Lenovo R61. Under Ubuntu 7.10 wireless worked fine, using the restricted driver, but using 8.04 no LED and no connection seems possible.

[slomobile (slomobile)]

I can confirm this on HP laptop dv9335nr with Intel 3945abg. Worked fine in 7.10 and 8.04 beta until about a week ago. I stayed current with updates but just accepted them blindly, sorry not sure what updates caused issue. I then installed 8.04 final and it never worked. In 8.04 beta, network manager applet failed to display prompt for wpa password. In 8.04 final nm applet disappears from notification area but continues to appear in current session. Wired network is functional but Ubuntu doesn't seem to notice when cable gets disconnected.

I am using a Lenovo T60, and I thought it wasn't working either. I finally discovered after looking at the logs that it does work, but that the wireless LED does not work. However, I have a problem with the network manager. I am using WPA2, and after I select WPA2 and put the passphrase in, it works. However, when I go back into the network manager it has reverted to WPA. And after rebooting, I have to go back into network manager, select WPA2 AND put the passphrase in again to get it to connect. Also, I am unable to enter anything into the nm-editor.

My wireless bcm 43xx dos not work too, the driver native is not work

The same problem here.
My 3945ABG worked perfect unter Ubuntu 7.10 and with Ubuntu 8.04 it doesn't even iwlist anything.

[mperezs (mauricioperezs)]

The problem is not related to Ubuntu version but with the kernel version. I have the same problem and was able to make the wireless work changing the kernel back to version 2.6.20-16-386 or earlier.

The problem start when the kernel was upgraded to 2.6.22-xx

Give it a try to this and comment.

Good luck.

[mperezs (mauricioperezs)]

Sorry, the working kernel version is 2.6.22-14-386 anyhow the other one should work anyway. The problem started with kernel upgrade to 2.6.24-xx

[8200 (8200)]

Hi mperezs.

I have only got kernel 2.6.24-16; 2.6.24-17; 2.6.24-18 on my acer with Ubuntu 8.04. So I can't test.

But when I boot with Ubuntu 7.10 (live-cd) it works.

[Sue Ori (orisue)]

Hi. Same with my ACER 5672WLMi. All ok on 7.10.
8.04: No wireless networks visible (scanable). Card detected correctly as shown in dmesg etc...
I am not able to find the old kernel versions, hints very much appreciated how to get around this bug. Or I go back to 7.10 [deep sigh].

I have hp 530 notebook and I am able to connect to my University's (un-secure) wireless network from the very beginning after installing 8.04. But the LED does not work. LED used to work in 7.10 , where ubuntu used restricted drivers.

[Johnson (jaxit)]

same problem in samsung R25

[8200 (8200)]

Is there a solution or workaround for this bug yet?

I need to use my wireless card and don't know how (with Ubuntu 8.04).

Thank you!

[NetWorker (davis-jeff)]

I haven't seen a fix for this bug, but you can make it work. It didn't work with 7.x either. What I have found with my T60 is this:

The Thinkpad wireless LED does not work with Ubuntu. Don't let this throw you. It is on if the switch is on, the LED just doesn't work.
I use WPA2 encryption. Every time I boot into Ubuntu I find that it has reverted to WPA. I have to manually change it to WPA2 and copy/paste the encryption key in order to get it to connect.
If you still have problems check the syslog. Also try "ifconfig wlan0".

If you are still having problems send me the relevant syslog messages and the output of the ifconfig command.

I am using WPA2 encryption

Two days ago I tested a few thing (ndiswrapper, wicd, iwl3945 options, hardy-backports etc.) many hours late at night and I even found a solution which works sometimes (before that it NEVER works):
There must be a bug with network-manager - try wicd instead and your wireless will work better.

But todady I switched to debian 5.0 beta and here I only got to copy one file (iwlwifi-3945-1.ucode) to /lib/firmware, also installed wicd and it just runs smooth 8-)

Can you reproduce this bug with a supported Ubuntu version? Thank you for telling us!
