DNS doesn't work for me after reboot either.
My workaround is to manually add DNS entries to /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
I previously tried adding these via gnome-control-center, but it doesn't
respect these settings.
$ lsb_release -rd
Description: Ubuntu 18.04.1 LTS
Running 'sudo rfkill unblock wifi' alone is NOT a workaround.
After toggling 'Turn off Wi-Fi to save power' to OFF, gnome-control-
center wifi reports "No Wi-Fi Adapter Found".
The only 'workaround' is to leave 'Turn off Wi-Fi to save power' set to
ON, and to run 'sudo rfkill unblock wifi' on
Public bug reported:
The 'Turn off Wi-Fi to save power' setting defaults to ON.
Toggling 'Turn off Wi-Fi to save power' to OFF causes the wifi device to
be soft blocked.
BEFORE$ sudo rfkill list all
0: hci0: Bluetooth
Soft blocked: no
Hard blocked: no
1: phy0: Wireless LAN
