The actual transfer speed of USB 3.0, 3.1, 3.2, and/or Type-C will vary depending on many factors including the processing speed of the host device, file attributes and other factors related to system configuration and your operating environment. The package provides the installation files for N300 Micro USB WiFi Adapter - N300MA Driver version 1015.4.1230.2011. If the driver is already installed on your system, updating (overwrite-installing) may fix various issues, add new functions, or just upgrade to the available version. USB issues often, but not always, relate to drivers problems. It is recommended you update your USB Drivers regularly in order to avoid conflicts. You can download a Driver Installer to run a free scan to check if your drivers are up-to-date.
