I recently get new Sabrent USB wireless adapter, but I am not able to get my Sabrent USB wireless adapter to work, please help me as I am a beginner in Linux. Sabrent manual has two methods one is by compiling a driver from the source code, but there are not any instructions of how to do it and I am lost. And there second option is by copying the firmware files directly to the lib/firmware folders. I did that but when I ran sudo ./wlan0up and sudo .wlan0down, but everything I do results in a “Could not get interface for wlan.” Please help me.
