Created attachment 287521 [details] dmesg dump I am on Arch Linux. Hardware: Acer Aspire A515-51 lspci: 02:00.0 Network controller: Intel Corporation Dual Band Wireless-AC 3168NGW [Stone Peak] (rev 10) firmware-version: 29.163394017.0 arch firmware package: linux-firmware 20200204.b791e15-1 Wifi connection sporadically disconnects, presumably under heavy load and then tries to reconnect to the AP, sometimes immediately, sometimes not for some minutes. Error mostly occours while downloading larger files. Simple SSH connection seems not to trigger that error, respectively I did not encounter...

Created attachment 287553 [details] second dmesg dump with 2 hw resets
I downgraded the firmware by renaming iwlwifi-3168-27 iwlwifi-3168-29 to iwlwifi-3168-27.ucodeBAK iwlwifi-3168-29.ucodeBAK and its now using iwlwifi-3168-22.ucode (firmware-version: 22.391740.0) No hw restarts since an hour or so, even with heavy traffic.
cheered too soon! It also crashed with the 22 firmware. Same error message.
DB cleanup. Please re-open if still relevant. Thank you.
