WiFi Issues On Dell Inspiron 1521

Post by vw98075 »

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?

Install ukuu ,Ubuntu kernel update utility. With ukuu, install latest version of 4.9 kernel version.Reboot and test.

Code: Select all
