Wifi disabled after suspending

Hi guys, newbie Ubuntu MATE user here. i have this problem where whenever i suspend my laptop (closing the lid) disables WiFi, and i don't know how to enable it back. is there a command i can do? maybe a script? i've seen this is a well documented issue, but i've tried multiple solutions to no avail. i'm not very experienced with Ubuntu yet, so please explain it to me clearly.

Here's my uname info:
Linux plex 5.0.0-31-generic #33~18.04.1-Ubuntu SMP Tue Oct 1 10:20:39 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

cheers!

(forgot to say i'm using Ubuntu 18.04.3 LTS x86_64)
