@kamlesh365 Hi,If you perform speedtest on a single PC, you will not get the result you want (200).Actually, Load Balance selects which WAN port is session-based. If you use FTP to download a video, PC will establish only one session with end-point. When you have a lot of sessions with end-points, Load Balance router can assign these connections to different WAN ports according to router’s policy, in this way all the bandwidths of WAN links are in good use to speed up the whole traffic. That is why Load Balance router can aggregate several WAN links together.
