Bug Description

Hello Team,

Env - Dell XPS 9570
      Ubuntu 18.04.2 , HWE kernel

We are facing intermittently wifi reconnection issue on Ubuntu 18.04. Software upgrade is up-to date. Also some time we facing freezing issue due to this hard reset required to make machine back to normal.

This wifi drop and freeze issue happens only in home wifi networks. Not on home networks.

I came to notice this https://www.dell.com/support/article/it/it/itbsdt1/sln306440/xps-13-9360-ubuntu-killer-wireless-n1535-manuale-aggiornamento-firmware?lang=it here they manually adding the wifi firmware. I will try this later. Before that latest 18.04.2 LTS wifi inbuild driver doesn't supports this Dell XPS 9570 wifi driver? Please confirm.

I will share the required logs in next update

May I know what about Ubuntu 16.04 LTS, does this driver included or not ?

Does this kernel supports Killer 1435, 1435s and 1535 wireless cards ?

>> linux-image-generic-hwe-18.04 = 4.18.0.17.67

Or support for this wifi cards available in 5.x kernel, please specify.

Note:- As per killer networking, they haven't mentioned about 18.04
https://support.killernetworking.com/knowledge-base/installing-the-killer-1535-1525-1435-in-ubuntu-debian/

Please confirm which linux-firmware supports this driver?

Does any of the linux-firmware supports these killer wifi driver ? http://mirrors.edge.kernel.org/ubuntu/pool/main/l/linux-firmware/

Issue:- Intermittently reconnection / sometime freezing issue. Mostly seeing this in home network.

Does downgrade the linux-firmware package help?

Jay (jayram1989) wrote :

@kaihengfeng, no downgrade also not helped
As a workaround we replace to Intel wireless 8260 , 7360 card. But this is not acceptable, we have more than 10x users working on Dell XPS 9570 , 9560 models. Please suggest

Please test latest mainline kernel [1] and latest firmware [2]. If the issue persists, please attach `dmesg` output when the issue happens.

@kaihengfeng sure I will test this on 18.04.2 LTS and will update you..

@kaihengfeng, one question with the installation of https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/ , I can only see .tar.gz file, and no .deb pkg for this. Can I dwld this .tar.gz and extract this under /lib/firmware ? Please confirm
