Knowing the following will give you a better product experience. 1. The specification of this wireless USB adapter is 1300Mbps (2.4G: 400Mbps; 5G: 867Mbps). A router with 1300Mbps or above can maximize the performance of our USB wifi adapter. It has nothing to do with the quality when you can't get the maximum speed. The network environment, router, barriers, laptop and PC 's internal memory…the interference of many factors can affect the speed. 2. Please plug the Wi-Fi dongle into the USB ports behind the computer host if you have a desktop. This way will let the Wi-Fi dongle get enough power to stay stable. 3.
