Why my wired local network link speed on the computer shows 100 Mbps when the router says it is 150 Mbps/300 Mbps capable?

As we explained above, 150 Mbps/300Mbps refers to the maximum wireless link speed. The wired local network link speed is decided on the capability of router’s LAN ports, the characteristics of Ethernet cables and the Ethernet Adapter of the computer. If the router has 100mbps LAN ports, the local network link speed will show 100Mbps.
