Comment 64 for bug 1589401

Mathieu Trudel-Lapierre:

I don't think you can expect all people affected by this (alot!, I have probably helped 10 people on reddit, and many on askubuntu, see http://askubuntu.com/questions/761180/wifi-doesnt-work-after-suspend-after-16-04-upgrade/761220#761220)

That being said, I have some new information for you. Regarding this bug (not the one with lockscreen!)

- I CAN'T reproduce with broadcom, seems you might be right about Intel wifi.
- With Intel I can reproduce right after a reboot with using suspend from menu or losing the lid.
- sudo systemctl suspend does not seem to be affected. Strange as that is.

I have also downloaded all the new firmware drivers from kernel and put in /var/lib/ it was messing quite a few, dmesg with errors. Same problem.

Hope this helps you :)
