Linux Mint 18.3: sudden problem with Wifi

[oops]

I am also having wifi problems with Mint 18.3. All the sudden my Dell laptop keeps dropping wifi connection and won't reconnect until i reboot. It happens whenever i close the lid and the laptop suspends. Now it does it kind of randomly even after rebooting. Also, I have 4 computers in my network running Mint 18.3 KDE and every single one of them suddenly are unable to download and install packages with synaptic. I get a broken packages error on all of them. After hours of reading and trying different proposed solutions nothing has changed. I've been with Mint for almost five years but I can't have a system that I can't use.

Those tips should help

instead of rebooting, just use Control-Alt-Backspace and reboot the desktop only, much quicker.

until you find the fix.

for me though, just simply toggling off the WiFi button, and wait 5 seconds, and toggle it back on, does the same thing

But why should a Mint user have to keep reconnecting his wifi? It worked almost flawlessly for five years.

Try booting from a previous kernel.

Switched off Wifi power saving permanently which solved the Wifi dropout problem.

However, at least every week Chromium crashes and hangs up the whole system, started with version 66.
Changed to Manjaro Gnome stable (without wifi power saving) and all problems are solved.

Bye bye Mint 18, you are not as good as Mint 13 and 17... Hope 19 will be better because I still like you, but for now I'm very happy with Manjaro.
