I upgraded from 16.10 to 17.04 and my laptop connects to home wifi but acts as if the network is not working, no website would load. It's not the browser, none of the apps work. A dozen reboots of laptop and router did nothing. Other laptops (win7), phones and tv use this network without issues. All was fine this morning but then the home wifi just stopped working on ubuntu (after waking it from sleep). For a few minutes it worked fine connected to the extender of that home wifi but then stopped that too. Ubuntu connects and uses my mobile hotspot without issues, so far. Any ideas? None of the fixes in previously asked similar questions worked for me so I was told in another thread to ask my own question.

Here is a link of the bug.

And here is what you should try:

Open a terminal and type or paste this and run it:

sudo -H gedit /etc/NetworkManager/NetworkManager.conf

Then edit the file and add these lines to the bottom of the file:

[device]
wifi.scan-rand-mac-address=no

Save the file and run this command in a terminal:

sudo service network-manager restart

Wild guess, have you tried changing your DNS?

sudo -H gedit /etc/resolv.conf

change nameserver 127.0.0.53 to nameserver 8.8.8.8, save & close.
