Hi papa kay and welcome to LQ.

Some things to include are the specifications for the hardware in your system. Do you know that you have a wireless adapter, and anything about the model? Or will you need some guidance on how to find that information from your system?

For instance, "lspci" is a good command to show the devices in your system. Also "sudo iwconfig" will show whether or not a wireless device has been detected and has a driver assigned for it, also potentially working.

Consider using those commands and posting the outputs here. Also please give some information on your system if it is a standard PC where someone can look up the specs by manufacturer name and model number.

Welcome!

I had a similar problem with an old HP laptop and Mint 17.3. Turned out that the wireless was from Broadcom, and most linux distros do not support their hardware out of the box. As I recall, I connected to the web by ethernet and clicked on Administration --> other drivers. That installed what was needed, and my wireless has worked fine since. If this works, it's a quick fix. If not, then the solution will take longer.

This thread may be helpful, though some details have changed.

Good luck.

You probably need the firmware package for you wireless adapter. There are different firmware packages for different brands of cards. You install them through the package manager.

Code:
$ lspci
will show you which brand of wireless adapter you have. Then, just install the firmware package with that name, i.e. firmware-intel.

papa kay,

Congratulations, you have a Realtek wifi card (this manufacturer's cards can be a real pain in Linux).

Having said that, this link should provide a solution to your problem:

The selection of the antenna is part of things, however it may also be that the WIFI adapter is not yet installed in the system.

This is where the output of iwconfig would be helpful to know if the adapter is working already versus not.

Here are some links which I found (untried), but seem to guide you to installing and loading the driver for this adapter.

http://ghoshbishakh.github.io/blog/b...8723be-hp.html
http://www.linuxlinx.com/2016/05/ins...linuxmint.html

They have slightly different details, but they seem to be saying the same advice:
  • Download the driver
  • Install build tools
  • Build the driver
  • Install the driver
  • Load the driver
  • Some suggestions for alternative methods to get it working, and then how to validate that it is working
