I've tried the "temporary (and embarrassingly crude)" workaround, which seems to be doing the trick using sys-kernel/gentoo-sources-2.6.31-r6.
Have you tested with gentoo-sources-2.6.32?
(In reply to comment #5) > Have you tested with gentoo-sources-2.6.32? > Unfortunately same problem with gentoo-sources-2.6.32.
I meet the same "Unknown error 132" problem. However, my wireless card (IWL3945ABG) is still usable. The problem is occurs after I update my kernel to 2.6.31-r6. My old kernel is OK and its version is 2.6.30-r8. This problem doesn't prevent me to connect to the net, but if I switch the card off and then turn it on, ifplugd is unable to do the reconnection, and I have to stop the /etc/init.d/net.wlan0 and restart it.

I had to remove all iwl4965-related modules via rmmod, modprobe them again and the wifi worked. I could live with that... Now I can't connect via wifi at all.
Same problem with iwlagn on my brand-new Dell Inspiron 13z w/ IWL5100 (haven't tested anything older than 2.6.33-rc1). Workaround: disable RF kill switch in the BIOS (it had a name like "Wireless Switch" or something)
I had this problem using kubuntu 9.10 on a sony vaio but it seems that it's been solved now (fingers crossed). I had been trying to play with rmmod and modprobe (reloading the drivers modules) but was not successful. Try this: - su - rfkill block all -- switch off wlan from hardware switch - rfkill unblock all -- switch on wlan from hardware switch If this does not work yet, go to the software repositories, and download and install all sources, headers, backport modules, etc related to your kernel. Hope that this could have been of help.

It seems that this bug totally prevents ifconfig to configure the card (ifconfig is even unable to turn on the interface). Although with some problems, wpa_supplicant is still usable. I hope this information can provide a workaround.
Help me figure out if I got this right: You gentlemen are all getting "rfkill is enabled; disable it to proceed" errors. You have no hardware rfkill switch, right? [1] Your laptop manufacturer has a key binding to disable/enable rfkill, but it just doesn't work in Linux. If you were to add the key binding yourself (like comment #2's link suggests), everything would be fine, right? If I'm right on the above, I *think* that the laptop-mode mailing list is the best place for this. [1]: If you do, just switch it's state and you are done.

I'm not sure what the "rfkill switch" is, but I have a small switch on the side of laptop to switch on/off wifi. If I turn wifi on, I'm still not able to run wireless connection. However I haven't something like "laptop-mode" installed before and the wireless connection worked. So I don't know how to report this bug, because I don't understand the problem at all.

If you turn off the switch, no OS can turn on the card.
I've found the rfkill utility and used it: # rfkill list 4: hci0: Bluetooth Soft blocked: no Hard blocked: no 5: phy1: Wireless LAN Soft blocked: no Hard blocked: no So apparently it isn't switched off. Then I try to take it up: # LC_ALL="C" ifconfig wlan0 up SIOCSIFFLAGS: No such file or directory # LC_ALL="C" dhcpcd wlan0 wlan0: dhcpcd 4.0.15 starting wlan0: read_interface: No such file or directory
