I installed Linux Mint 18.3 Sylvia Cinnamon as a dual boot setup on my old Dell Inspiron 1521. Since then I observe 3 WiFi issues on the Linux Mint.
First, I need to insert a Wifi Adapter on Linux Mint installation to get a WiFi connection while I don't need to do so on the Windows 7 installation.
Second, the WiFi connection will be disconnected after the laptop is put to sleep.
Third, the WiFi connection will be disconnected for a period of usage.
How to solve the above WiFi connection problems?
