There's a problem I have with the Wifi connection on my Acer-Aspire-E5-575G-Laptop with the newest Mint (18.3). I randomly get disconnected. Then I have to switch Wifi off and on again via control panel in order to have it work correctly afterwards until a new boot. I noticed that this always happens when the computer automatically "changes bandwith" (why???), see below. I only hope some Linux Mint expert can solve this problem. Thanks in advance!
Additional info:
There's no such problem when I run Mint from a "Live-USB-Stick" or under UBUNTU (which Mint derives from)!
Can anybody tell me please why that is?
