Ubuntu 18.04 wifi doesn't work after update
4
I'm running Ubuntu 18.04 on a Dell Precision M6400. When first installed 18.04, WiFi was running fine. After automatic update, it doesn't any more.
WLan spots are displayed correctly, but when trying to connect it fails after about 1 min, a message appears: Connection failed.
Updated and upgraded already, but no success. Looks, like the driver / firmware is no more correct after update.
Any hints?

Sorry if I am asking the obvious...but have you tried a full shutdown & turn back on? I've had a couple of updates recently where I've had to do that after the update seemed to break something (not the same as your problem though).

Please edit your question to add the result of the terminal command:uname -rIf you interrupt the boot process at the GRUB menu and boot into an earlier kernel version, is the issue solved?

@B.Tanner: Yes, shut down many times in between.

@chili555: tried to boot into earlier kernel, both normal or recovery mode. Not successful, it didn't boot up. Locked up in an endless loop. Thanks so far.

Can you temporarily connect with ethernet and try:sudo apt install --reinstall linux-image-4.15.0-32-generic linux-headers-4.15.0-32-genericand then try the GRUB menu again?
