How to speed up a Wi-Fi router?

Question

WiFi

My ISP gives me a speed of 100 Mbps. When connecting a twisted pair cable directly to the network card through the speedtest.net service, it gives almost 90 Mbps. When I distribute through the Asus RT-N10U router, the speed through the same service is already 18 Mbps. A friend said that you need to tweak the router settings, frequency, etc., and not sit at the factory. Tell me, what parameters can be changed on this type of router?
