Internet speed reduces, once i switch to wifi

[bbalthazar]

Hello, im having a problem with internet speed, that comes from router. My speed is 70-80mbps, and if i LAN from modem to pc, i am getting that speed, but whenever i switch to the WiFi, speed get reduced twice.
Modem - centurylink
Router - ASUS AC1900
Pc wifi card - up to 300mbps
Pc is right next to the touter
I have a couple pc, and they all are getting same reduced speed.

One other thing, is that the modem, has integrated wifi, and if i do switch to that one, speed gets reduced as well.
