Dual Band Usage Instructions:
1. You must have a dual band WiFi router with 5G band if you want to have a 5G signal.
2. The adapter's max speed up to 867Mbps just works when you connect to 5G band, otherwise, it will just run at the max. speed of 300Mbps with 2.4G. Normally, your PC's network speed can't up to the wifi adapter's speed as it depends on many factors, Such as the network size，router, barriers, laptop or PC 's internal memory.
3. If your computer is desktop, speed is not ideal, you can try to insert the WiFi adapter into the USB3.0 of you PC, that may assure the power supply.

5. If your WiFi adapter is closed to the router, and you want to have fast speed in watching video and playing online games, we suggest that you should connect to the 5G band. If your WiFi adapter is far away from the router, and you just want to surf the website, you'd better connect to 2.4G band for better and stable signal.
