I am having two Ruckus R510 access points.My internet service provider is offering 900 mbps speed but WiFi speeds are only 400 Mbps max. I tried changing channels from auto to Speicific ones and changed tired by changing DNS but none of them improves my speed.Is this an issue with Ruckus R510 models? How can I get more speeds(Atleast 700-800mbps) on wifi with R510.
