When I first moved across to Linux and tried a number of distributions from Linux Mint, Ubuntu and PopOS; I found that I was having the same issue when trying to get my wireless connection to work on each of the systems.
Coming from a Windows based Operating System to Linux and facing this issue was almost enough to send me back to Windows. Though having spent a lot of hours online searching for the solution I stumbled across the below which I hopes helps others that are having the same problem.
I am using a TP-Link Archer T9UH v1 [Realtek RTL8814AU]. The last part of this description ‘RTL8814au’ is the driver name that I need for this wireless driver to work.
You can take a look at your own system and see if this also matches what you have. Do this by opening the terminal and typing:
This terminal command shows all the usb connections that are connected to your machine. The top one in my case is my wireless wifi from TP-Link who have stopped their Linux support for the latest release.
If you find you have a different driver you can try searching this in google, or if this is not working taking the 8 digit identification number and searching that for a driver. In my case this number is 2357:0106. Though you may want to try this driver if you have no luck with others as I have seen others that this has also solved their wireless connection issue.
Open the terminal and type the following commands:
git clone https://github.com/aircrack-ng/rtl8814au.git
sudo make install
Restart you computer and now your wireless issue should be solved!
