Posted: Sat Oct 06, 2012 4:28 am Post subject: [SOLVED] Linux Kernel 3.6 - No more wireless

Hi,

I tried to update to the Linux 3.6 kernel today, but I'm having issue with wireless. 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 wpa_supplicant, 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

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.

wlan0 no wireless extensions.

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 CONFIG_CFG80211_WEXT in your kernel. wpa_supplicant should be passed the -Dnl80211 parameter.

Code:

# iw dev wlan0 scan

I tried it, didn't change anything.

No, I did the configuration myself from scratch.

I didn't see anything of interest in that stuff

Does someone have another idea ? Or perhaps, does someone understand the outputs better than me :oops:

?

The output looks totally fine. The kernel detects and drives your wireless correctly. wpa_supplicant does spew some errors, but that is normal. Just make sure that it is called with -Dnl80211 parameter.

The thing is that it works when I switch my kernel with the exact same configuration. So, imho, I doesn't comes from configuration flag ?

anything at /var/log/wicd ?

have you poked around the wicd gui? you can set nl80211 as driver there and order connection

your iw output is missing the magic word

anything at /var/log/wicd ?

Nothing of interest. There are only a line about the fact that no network has been detected...

have you poked around the wicd gui? you can set nl80211 as driver there and order connection

Yes, I tried to change the driver from wext to nl80211, but it didn't change anything.

You're right. When I'm running my 3.5.4 kernel, it has the associated magic work in it. What can I do "associate" it ?

After the recompile please try both wext and nl80211 drivers with wicd and post your findings. _________________ Defund the FCC.

Code:

[*] cfg80211 wireless extensions compatibility

Using that is generally not optimal. This is why the kernel disables it by default. Wireless extensions exist only for legacy compatibility, and they will not offer regulatory domain support among other things (so you will be in "world" domain with limited txpower and passive scanning only). Finding what still uses wext and switching it to nl80211 would be a better idea.

@ wichtounet does wicd and 3.6 kernel work with [*] cfg80211 wireless extensions compatibility compiled in? with driver wext? with driver nl80211? _________________ Defund the FCC.

@chithanh
Possibly the nl80211 driver doesn't use the extensions and doesn't care if they are available.
Even with [*] cfg80211 wireless extensions compatibility, going to nl80211 driver did increase my reported bits per second from 150 to 240. Thanks for that.

Edited to remove statement that
