Comment 7 for bug 1993890

I've tried a suggestion from https://ubuntuforums.org/showthread.php?t=2480193 but after rebooting that didn't get wthe wifi working:
echo 'options iwlwifi power_save=0 uapsd_disable=0' | sudo tee -a /etc/modprobe.d/wifihacks.conf
echo 'options iwlmvm power_scheme=1' | sudo tee -a /etc/modprobe.d/wifihacks.conf
