I could authenticate and use WPA2 PEAP WiFi for now. So, if any, it seems specific to the model. -- You are receiving this mail because: You are on the CC list for the bug.

Sometimes it works, and it often works if you unload the module and reload it. Or do you mean there are changes and it should be fixed now? -- You are receiving this mail because: You are on the CC list for the bug.

Skimming over net indicates that it's an issue that can't be easily fixed: https://bugzilla.kernel.org/show_bug.cgi?id=190281 Intel couldn't spend development resource for the older chips like this... -- You are receiving this mail because: You are on the CC list for the bug.

I'm also not able to reproduce it here, it looks like it happens most of the time with a Fritz!Box 7330. Looks like a Packet of Death from the Fritz!Box :-) Looks like I need a workaround like: if dmesg | tail -50 | grep "Call Trace"; then rmmod iwldvm iwlwifi mac80211 cfg8011 modprobe iwlwifi fi Not sure if this works as NetworkManager dispatcher script. -- You are receiving this mail because: You are on the CC list for the bug.

If yes, any chance to check with Leap 15.2? Although it's a kind of bugs we can't fix in our side easily (basically a firmware bug), the newer kernel might have a better chance to get fixed. -- You are receiving this mail because: You are on the CC list for the bug.
