HOW TO INSTALL WIFI DRIVER IN LINUX MINT 19


Did you realize that your newly installed Linux Mint 19 operating system can’t pick up on the several wireless connections available in your area? The only alternative is to use an Ethernet connection.

This article will deeply explain how to connect your Linux Mint 19 operating system to a Wi-Fi connection, update wireless drivers in Linux Mint 19 operating system, and how to troubleshoot wireless connection problems in Linux Mint 19.

Wireless connection problems in Linux Mint 19 will always be so strange to Windows users. Windows users who had been using Windows 8 or 10 and decided to explore the Linux environment may be stranded since Windows usually install the wireless connection drivers by default, which is opposite in Linux.

Solutions on How to Fix the Wireless Connections in Linux Mint 19

There are several methods to go through this and make your Linux operating system detect the wireless connections available in your area. You need to know that some of the ways may work or fail to work for you.

It would help if you attempted all the listed solutions until you find one that enables your Linux operating system to detect the available wireless connections.

Here are some of the few solutions that hopefully will work for you and make your Linux detect the available wireless connections:

  • Check if the wireless adapter is installed properly
  • Broadcom Chip
  • Reinstalling your Realtek wireless driver driver  
  • Update
  • Using ethtool

Solution 1: Check if the wireless adapter is installed properly

This is precisely where you should begin with. At some point, this only can make your Linux detect the available wireless connections in the vicinity.

Here are the steps you need to follow:

  • Open the Driver Manager. This will help you find if the wireless adapter was installed correctly. (You will always find the Drive Manager in the second column just after clicking on the Administration that is in the first).

            You may then see that a Wireless adapter isn’t installed and that you need an Ethernet connection or Linux Mint on USB to have it installed.

  • Use Ethernet or USB disk and switch from “do not use this device” to the device questioned and select on apply changes afterward to install the necessary drivers.
  • Wait for Linux to get the correct drivers via Ethernet or the Linux Mint copy located on the USB Disk that you used to install the operating system from.
  • Check if the wireless connections are available by clicking the symbol of the connection situated at the system tray.
  • All you need to do now is to select the right wireless connection from the list and proceed by entering the password to get connected.

Did that only work for you? If so, congratulations, but if it failed or you found that the wireless adapter was successfully installed, let’s move to the next solution.

Solution 2: Broadcom Chip

This method may make the wireless connection work in your Linux operating or may not work for you. 

At this point, you may be so desperate to try everything to bring your wireless connection. So, try this.

Here are the steps you need to follow:

  • Plugin your Ethernet cable
  • Click software manager
  • In the search box, type Broadcom and press Enter
  • You should then download the “Broadcom-sta-common and Broadcom-sta-source.” (Download both of them).
  • It would help if you then went back to the menu and in the search box type additional drivers.
  • Wait for the search to complete.
  • Your Ethernet connection will stop, and you will notice a pop up with “Broadcom B43 wireless driver and Broadcom STA wireless driver”.
  • Select on the Broadcom STA wireless driver and activate it.
  • You will then be able to connect to your wireless connection.

I hope this worked for you, and if it failed, try the next solution.
