On which operating system are you getting this error message? It is possible that its necessary drivers are installed properly but software is not. Please check if the WiFi icon is coming into the system-try or not.
If this does not happen in your case, then uninstall the Quantum application / driver if it is installed on your computer. If it is not installed, then reinstall by right clicking on it and choose “Run as administrator” mode.
If both things don’t work either, then you’ll have to install its core basic driver manually on your computer. Please let me know if you need its basic driver, I’ll provide it to you.
