Having this weird problem for some time. Wifi (5GHz) disconnects after some time; Restarting networking basically hangs the system. On the latest kernel as of now
sudo service networking restart

Solution tried but not working
Solution tried- Set power saving to off; Default was 3; Set it to 2
$ sudo cat /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
wifi.powersave = 2
Reboot is needed after this
