#2

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?

@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, 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

I'm able to reproduce this with QCA6174 802.11ac Wireless Network Adapter on a Dell XPS 13 9370 (07E6). From a bit of googling this seems to be a widespread problem, but only mentioned solution is to replace the wifi card, as also mentioned in this bug report.

Jay, did you have any success from testing the newer kernel + firmware?

@bryce no luck, I tried with latest kernel and for failed to apply linux-firmware as per #28. So I moved to replace the wifi card.

That's too bad it didn't work, but thanks for testing it. I've read suggestions that it relates to bluetooth, so am currently testing with that disabled in bios, but I don't have high hopes. If it doesn't, I'll probably just go with the replacement option myself.

These Dell XPS series laptop mostly comes with these killer wifi. It's better Dell to collaberately work with ubuntu to fix the issue.

Have you tried this - https://www.dell.com/support/article/ba/en/babsdt1/sln306440/killer-n1535-wireless-firmware-manual-update-guide-for-ubuntu-systems?lang=en any luck?

Thanks, I've installed that firmware update and will give it a try.

As I expected, disabling bluetooth in BIOS didn't resolve the issue.
Apparently in the Dell XPS 13 9730 the wifi card is soldered to the motherboard, so replacing it is sadly not an option.

I'm also keeping an eye on https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1799988 which seems relevant at least to my case.

The firmware update seems to have done the trick.
