Comment 2 for bug 1828578

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 ?
