Wifi on Lenovo ThinkPad s440

Postby Onsemeliot » 2017-06-30 05:37

I just upgraded a Lenovo ThinkPad s440 from Jessie to Stretch. Since I was already working on administrative tasks I wanted to set up wlan. Unfortunately proprietary drivers are needed. (i never attempted to use the non-free repository with Jessie.) Therefore, I followed the guide in the Debian wiki: https://wiki.debian.org/iwlwifi. I could install it but it refuses to accept the password for the wlan even if the password works fine on my own Jessie system.

Can anyone give me any clues?

Please reboot and post the output of the following commands
Code: Select all
uname -a
lspci -knn | grep -iA2 net
dmesg | grep iwl


Also, use `journalctl -f` to monitor syslog during rejected connection/authentication. Post the logs here as much as possible.

Thanks for replying, orythem27.

These are the requested outputs. (I did more than one try during recording the protocol.):

Right now you are using firmware iwlwifi-7260-17.ucode version 17.352738.0. Can you try downgrading firmware?

Firstly uninstall firmware-iwlwifi and remove /lib/firmware/iwlwifi-7260-17.ucode
Then download iwlwifi-7260-ucode-16.242414.0.tgz, extract and copy iwlwifi-7260-16.ucode to /lib/firmware
Reboot and use `dmesg | grep iwl` to verify loaded firmware version.

Or, try connecting to other wireless access points.

Sorry for taking this long to answer. Thank you for your tipps. I did update my main computer to Stretch also and encountered even more pressing issues there. Most notably the problem that the root authentification doesn't work. Even if I installed the system 3 times already checking the password very carefully. I hope I can work on this wlan issue soon again. I first need to deal with my main working machine ...

In the last days I tried many installs of Debian 9 (Lenovo ThinkPad s440 and Acer Extensa 5220), Trisquel 7 (Acer Extensa 5220) and Lubuntu 16.04 and 17.04 (Asus EeePC 1015PX) and I tested live sticks on all systems before. All those systems have the new installer with limited localisation options and authentication issues in common. On all systems I can use my wlan only without password protection. Today I even updated the Buffalo router. But it had no effect what so ever. (In the mean time an old Dell notebook with ubuntu 16.04 in the same network works just fine.)

To me it now very much looks like a problem which first appeared in Debian and did get spread to other distros using the same code base. It could be a systemd bug, considering that it even affects the root login in Debian ...

I finally managed to try what you suggested.
Code: Select all
# dmesg | grep iwl
[    2.141148] iwlwifi 0000:04:00.0: firmware: failed to load iwlwifi-7260-17.ucode (-2)
[    2.141215] iwlwifi 0000:04:00.0: Direct firmware load for iwlwifi-7260-17.ucode failed with error -2

Unfortunately "-2" as an explanation is not very helpful to me.
