Public bug reported: Ubuntu 19.10 Kernel 5.3.0-18-generic Hardware: Thinkpad T460p (also tested on T480s) with Intel 9260ac wifi card.
Expected: Wifi connects, uploads/downloads as normal Symptom: Wifi connects, as soon as an upload/download (any heavy traffic) start, the system comes to a crawl, becomes barely usable, and I end up opening a prompt to reboot. The system is unusable. This happens even with the Live USB version. The only solution I found was to download a different (newer) firmware. Latest version from: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi This is iwlwifi-9260-th-b0-jf-b0-34.618819.0.tgz I then manually copy the contained firmware to /lib/firmware, remove all other versions and make a link to iwlwifi-9260-th-b0-jf-46.ucode that the kernel expects to load. This completely resolves the issue. This is the carsh log (Thinkpad T460p, but identical to T480s, all fresh installs): -------------------------------- Oct 20 01:51:13 weywot kernel: iwlwifi 0000:03:00.0: Error sending SCAN_CFG_CMD: time out after 2000ms.
