Hi, I bought a new DLink DIR 615 N300. However instead of showing the link speed 300mbps, Windows shows it 150mbps even when the router is sitting beside the laptop. I am using a HP Pavilion 15-ab032tx with Realtek RTL8723BE 802.11 b/g/n Wi-Fi adapter. Is it beacuse 150mbps is the max speed of my WLAN card or maybe there is a problem with my router?
