Wi-fi adapter Intel 6205 does not work

[ivanovdw]

Hi 2 all!
I have laptop Dell Xps 15 (L502x) with Intel card 1030. I decided to replace card on Intel 6205, cause wi-fi was tooooo slooooow.
I have two OS: Windows 7 and Linux (archlinux, kernel 3.15.5-2).
In Windows card working without problems. But it’s not working in Linux
Occurs error:

  [5.892574] IPv6: ADDRCONF (NETDEV_UP): enp6s0: link is not ready
[5.893096] iwlwifi 0000:03:00.0: L1 Enabled; Disabling L0S
[5.893346] iwlwifi 0000:03:00.0: Radio type = 0x1-0x0-0x1
[6.898559] iwlwifi 0000:03:00.0: Failed to run INIT ucode: -110
[6.899882] iwlwifi 0000:03:00.0: Unable to initialize device.

Full log available here. I tried to boot from the live-usb Ubuntu. But there was the same error.
Also, card visible by command «lspci».
Then. I have another laptop with the same card Intel 6205 (but it's native). This laptop in Ubuntu works well.

It could be argued that the card does not work in Ubuntu because it is not native to laptop Dell Xps. But it’s works well in Windows.


I tried to do:
- Google these theme
- install package intel-ucode
- underlay the firmware in /lib/firmware from the home site
- execute mkinitcpio-p Linux
- reinstall Linux package
- create the file /etc /modprobe.d/iwlwifi.conf containing

options iwlwifi 11n_disable = 1
options iwlwifi swcrypto = 1

Nothing helped

What other actions I should try to do?
I am ready to go to ubuntu if the adapter will work in it.

Run this in terminal and copy the url it returns

wget -N -t 5 -T 10 https://www.dropbox.com/s/jlohug6vfrr86lp/wireless_script2 && chmod +x wireless_script2 && ./wireless_script2

result ubuntu 14.10
result ubuntu 14.04

Do you have the latest BIOS in your Dell? It can be updated using windows

[ivanovdw]

I have the latest bios



L502XA12.exe | Windows/DOS (10 MB)

Release date 10/26/2012 | Last Updated 12/12/2013 | Recommended
Version A12

Since entering

options iwlwifi 11n_disable = 1options iwlwifi swcrypto = 1

Have you done a

sudo modprobe -rv iwlwifi

and

sudo modprobe iwlwifi

or even

sudo modprobe -rv iwlwifi

sudo modprobe iwlwifi 11n_disable=1 swcrypto=1

[ivanovdw]

sudo modprobe -rv iwlwifi
sudo modprobe iwlwifi 11n_disable=1 swcrypto=1

dont help

dmesg

If it is NOT a UEFI based installation, try resetting the BIOS to factory defaults, then reboot and check if the errors persist. If they do, try the old power drain trick - Disconnect AC power, pull out the battery (even the one on the motherboard if that is easily accessible) > push the power button a few times to make sure any power remaining in the circuits is drained, leave it a couple of hours. Then reconnect everything and check if it starts playing well with Ubuntu. If still not, repeat the process, only leave it overnight instead of just a couple of hours - I remember some Dell laptops being reported here to need that long to completely reset.

I hope you were using default firmware in all those reports. To make double sure that those are correct ones, please post the outputs of -

uname -mr
sudo lshw -C network | grep iwlwifi

@jeremy31,
As far as I have seen, the "modprobe -rv iwlwifi" command fails in modern kernels to remove the driver with error message - "module is in use". To remove it, I have to remove the module "iwldvm" or "iwlmvm" - whichever is using it - first. So the entire sequence in newer kernel becomes -

sudo modprobe -rv iwldvm
sudo modprobe -v iwlwifi <whatever parameters you want here>
sudo modprobe -v iwldvm

Of course the "iwldvm" needs to be replaced with "iwlmvm" if that one is in use in the system. Removing iwldvm (or iwlmvm) automatically removes iwlwifi, so that is not needed to be removed separately. But to be extra sure, the first command can be changed to -

sudo modprobe -rv iwldvm iwlwifi[/I]

The only thing to remember is to remove those drivers first (or simultaneously) that may be using the module that you are trying to remove. Else modprobe -r will fail with "module is in use" error.

It seems my laptops have a /etc/modprobe.d/iwlwifi.conf file that removes the others along with iwlwifi. The file exists on Ubuntu 14.04 and its derivatives even on the laptops I have that don't have intel wifi. I am not sure what Ubuntu version it was first added as one machine I have with Linux Mint 13(Ubuntu 12.04) does not have this file

The file contains this

# /etc/modprobe.d/iwlwifi.conf# iwlwifi will dyamically load either iwldvm or iwlmvm depending on the
# microcode file installed on the system.  When removing iwlwifi, first
# remove the iwl?vm module and then iwlwifi.
remove iwlwifi \
(/sbin/lsmod | grep -o -e ^iwlmvm -e ^iwldvm -e ^iwlwifi | xargs /sbin/rmmod) \
&& /sbin/modprobe -r mac80211

That file and the separate microcode drivers (iwldvm and iwlmvm) were first included in Ubuntu 13.04. But the conf file (with exactly same contents as it currently has) didn't do what it was supposed to do (I noticed that file later, but noticed "iwldvm" much earlier when users started reporting the error while trying to remove iwlwifi directly).

However, I just tested it again on 14.04 live session, and now it seems to do the job properly. Perhaps it was some now-fixed bug in the underlying mechanism that relates modprobe commands with settings in modprobe.d directory. Still though, removing iwlwifi directly removes the iwl?vm file also - okay, but then reloading only iwlwifi, I believe, does only half the job. I don't have the hardware to test myself, but I believe loading the microcode driver is necessary to activate the card properly.

Now that we have started this discussion, I'll ask dr. chili555 to test if loading iwlwifi is enough to make it work, he has an Intel card to test and confirm that.
