For a while before upgrading to 15.3 I had to run “iwlist scan” on my laptop after each boot, but after upgrading to 15.3 I cannot get wifi to connect at all.
The hardware is Intel Dual band AC8265 in a Lenovo Thinkpad X270 with kernel driver iwlwifi.
Some details:
xenakis:/etc # iwlist scan
lo Interface doesn't support scanning.
eth0 Interface doesn't support scanning.

Where should I look next?
I have tried using ip to bring it up but it does not do anything I can detect.

Just to note I am not using KDE or gnome, window manager is fvwm with X.
The network was working before the upgrade but yes I have used “yast2 lan” many times to zero effect. I have also retyped the password in case it got corrupted. I also tried settiing the kernel driver from auto. I have looked for a log file but failed to find any error message.
The other machine that uses WiFi was ok after the same upgrade so I was not expecting any problems.
I found an old thread I helped with which shows how to get some diagnostic output from wicked and wpa_supplicant (involved in the wireless authentication/association). These
Follow the steps there to get the debug output required from the respective daemons. In particular the wicked.log and /var/log/wpa_supplicant.log at least. As the output can be lengthy, consider uploading them to susepsate. You may need to install the ‘susepaste’ package first. It can be used like this…
I followed the recipe and have got the wicked.log and wpa_supplicant.log an they are big. Trouble is the susepaste says
“Paste failed :-(” for both files
