I have installed Ubuntu 16.04 as a dual boot with Windows 10. I have a TP-Link wireless adapter, model number "Archer T2U". It works fine under Windows 10, but Ubuntu doesn't see it. I have no idea how to install a driver for this.
I found a help message somewhere that said to go to "System> Administration> Hardware Drivers", but as far as I can tell, I have no such folders or directories on my system. Keep in mind that I have only a couple of days experience with Ubuntu, and none with any other form of Linux. Also I have no internet connectivity on the target machine, so any files will have to be downloaded from a different computer and manually transferred to this machine.
