iwconfig & iwlwifi fail to connect to a WEP network

[Egor]

iwlwifi driver fails to connect to a WEP-encrypted 802.11bg network.
My wireless card is
>> Intel Corporation Centrino Wireless-N 130 (rev 34)

When I connect either via wicd or iwconfig, I get a message in dmesg
>> wlan0: link not ready;

iwconfig wlan0 key ****
tells me «operation unsupported for device».

This problem is constant, I cannot connect to the network at all. As soon as I reboot my computer to M$ Windows7, everything works fine.

Do you know if this issue happened in a previous version of Ubuntu, or is this a new issue?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v3.4kernel[1] (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text.

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

ubuntu 11.10 was also affected, the driver there was iwlagn. Actually, I discovered apport-cli just recently, that's why I haven't filed the bug earlier :)

I'll test mainline kernel, thanks for the instructions.

I face the same problem on 12.04; the moment I changed the router to WEP Security from WPA2, Ubuntu fails to connect to internet.

Is there a bug fix ? Are some other Drivers compatible with Intel Wifi cards ?

[Egor (gluk47)]

The problem is still here.
I've tested 3.4.0-030400-generic, the log is attached, it's pretty much the same (excluding version numbers :))

[Joseph Salisbury (jsalisbury)]

This issue appears to be an upstream bug, since you tested the latest upstream kernel. Would it be possible for you to open an upstream bug report at bugzilla.kernel.org [1]? That will allow the upstream Developers to examine the issue, and may provide a quicker resolution to the bug.

If you are comfortable with opening a bug upstream, It would be great if you can report back the upstream bug number in this bug report. That will allow us to link this bug to the upstream report.

The bug does not affect the kernel. It's something with wicd and, possibly, iwconfig (If I use the latter correctly). I'll look through the manuals to find out where to redirect the bug.

For now I use the following solution:
# iw wlan0 connect <essid> key 0:<key> && dhclient wlan0

[Egor (gluk47)]

The bug persists. I cannot auto-connect to the WEP-encrypted network.
iwconfig fails to connect,

# iw wlan0 connect <essid> key 0:<key> && dhclient wlan0
works just fine.

It'd be nice if at least wicd had an option to use iw instead of iwconfig.
