But there are something you should know before you make a complaint about speed. 1. You must have a dual band WiFi router with 5G band if you want to have a 5.8G signal. 2. The max. speed up to 433Mbps just works when you connect to 5G band, otherwise, it will just run at the max. speed of 150Mbps with 2.4G. 3. This WiFi adapter will not boost the speed of original router, it just transmit the wifi signal. 4. 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.
