I have a Intel Centrino 6200 AGN card on a Thinkpad W510. I use the iwlwifi driver from intel (not compiled as a module).
I tried to keep the same configuration from one kernel to the other. I'm no pro in network, so perhaps it is a simple issue that I do not understand, but I already spent some hours looking for a solution without success. There are no errors during the kernel boot neither in wicd boot. I can see my card in lspci with no problems.
Apparently my interface is not recognized as wireless: Quote: iwconfig lo no wireless extensions. Eth0 no wireless extensions. Wlan0 no wireless extensions.
If I try to run wpasupplicant, I have some ioctl issues that says invalid argument. I thought it was related to cryptographic libraries, but I verified, the options of both kernels are exactly the same. If I just change my kernel in grub, it works well without any change in configuration between the two.
I don't really know where to find a useful log for that. I would like a precise error Does someone have an idea of the problem? Or does someone has an idea about where to look like to find more information about my problem? Thanks a lot and sorry for the lack of information, but I don't know where to search Baptiste Last edited by wichtounet on Sun Oct 07, 2012 1:24 am; edited 1 time in total DONAHUE Watchman Joined: 09 Dec 2006 Posts: 7544 Location: Goose Creek SC Posted: Sat Oct 06, 2012 7:46 am Post subject: Does Code: lspci -k show iwlwifi as module and driver in use for the Intel Centrino 6200 AGN? Does Code: ifconfig -a show wlan0?
If so does Code: ifconfig show wlan0? Does Code: ls /lib/firmware/iwlwifi-6000-4.ucode show the firmware present? Does help in menuconfig for Quote: Intel Wireless WiFi Next Gen AGN - Wireless-N/Advanced-N/Ultimate-N (iwlwifi) show Quote: Depends on: NETDEVICES =y && WLAN =y && PCI =y && MAC80211 =m && HASIOMEM =y and Quote: Selects: FWLOADER =y && NEWLEDS =m && LEDSCLASS =m && LEDSTRIGGERS =m && MAC80211LEDS =m && IWLDVM =m m or y acceptable.
N needs correction to m or y. Code: rm /etc/udev/rules.d/70-persistent-net.rules On reboot udev will rewrite it for the devices. Did you copy the prior config for use on the new kernel?
If so did you use make oldconfig to bring it in? Dmesg is your best log for this problem.
Open /var/log/dmesg with a text editor and search for wlan0 and iwlwifi and mac80211. Defund the FCC.

It sees your wireless, just iwconfig needs the legacy wireless extensions which are disabled by default for any modern nl80211 based driver. Use iw instead of iwconfig, or if you depend on wireless-tools for whatever reason enable CONFIGCFG80211WEXT in your kernel. Wpasupplicant should be passed the -Dnl80211 parameter.
