Speed depends on connected device. At 2.4 GHz, real speed is 60% of physical connection speed. So look at connection speed of device you use . Than calculate and compare calculated and measured speed . If they match, that is maximum. If not , it is matter of settings. To achieve your max ISP speed go to AC standard and use compatible WiFi card or device.

Now I check c60 specs and it has 100 Mbit wan and LAN ports . You should get router with gigabit wan and LAN. So 100 Mbits is your max internet speed - LAN and WiFi.

I'm having the same issue here! Even in cable it doesn't go up to 95 Mb. If it doesn't have a Gigabit port why they sell it like "400 Mb compatible on WiFi!" Like these? I have 120 Mb on my house but I can't use it even on cable with Max speed!

I  bought this system because I have 200 Mbps but when I connect this wifi will not go over 100 Mbps even though it say it will do 450 Mbps
