I'm unable to establish connection to a WEP-encrypted 802.11bg network. I get a message «link is not ready» everytime I try.
The problem persists, making unusable one of the networks I need. As soon as I reboot my netbook to M$ Windows 7, everything works just fine.
I use ubuntu 12.04 LTS with vanilla 3.4.0-030400-generic (obtained from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-precise/ )
To connect I use either wicd or iwconfig, with similar result.

Have you tried using WPA-encrypted networks? Do they connect any more reliably?
WPA/WPA2 bg networks work without any problems. As well as unencrypted ones.
802.11n networks show significant packet loss rate (up to about 80%). Didn't figure out, if it was because of iwlwifi bug (and iwlagn previosly), or because of buggy cheap routers. The problem remained in M$ Windows; 802.11n at home worked dramatically slowly with Acer Aspire One 2 (AFAIK with ralink wifi card) and with some relatively modern MacBook. I had to configure my router to disable 802.11n to get acceptable connection rate.
I'm confused, are you saying you're using WEP with 11n? That's not even supported by the standard.

Sorry to confuse you. The comment was in response to the question about any other issues. Sure, the WEP-network is b/g.
In the passage about 11n I kept in mind WPA/WPA2 nets.
Let's keep the 11n thing out of this bug then and focus on the WEP issue.
Works for me. Can you run "iw event -t -f" while it's trying to connect?

iw event -t -f

Sure! Added as attachment, a connection cycle looks like:
1338390400.063965: wlan0 (phy #0): scan started
1338390400.100945: wlan0 (phy #0): failed to connect to 00:1b:9e:12:ce:55, status: 1: Unspecified failure
1338390400.101268: wlan0 (phy #0): scan finished: 2462, "ZXDSL531BII-1A0EE6"
The ESSID ZXDSL<...> is the network I'm trying to connect.
Hmm, that looks a bit like you're not giving it a key or something??
Maybe you can connect to the network using
iw connect ZXDSL531BII-1A0EE6 key 0:<your key>
iw connect ZXDSL531BII-1A0EE6 key 0:abcde
for a 5-character key. You can also give 10 hex chars, or 8 chars/16 hex chars for longer WEP keys.
Thank you, it works. That's strange: I copied a key from wicd config, just the same, as I provided to `iwconfig key`. So, this bug is invalid, I'll go find out what's causing the trouble. iwconfig, maybe.
//Not sure what new bug status to choose) Closed, resolved, or, maybe, rejected. Thank you anyway :)
Not sure what the problem is then, but obviously not a driver bug. Sorry I can't be of more help.
Looks like I can't change the status either... should probably be RESOLVED INVALID and then CLOSED INVALID
Thank you, I'm closing this.
