RUCKUS R 320 SLOW WIFI SPEED

[Lukman]

Hi,

I use R320 as my AP and have upgraded my internet speed to 300mbps from 100mbps. But the wifi speed that I can get is less than 20mbps, almost the time. So, how can I adjust the settings to get the maximum speed for my Wi-Fi?  By using LAN/direct to router, I can get the maximum speed as subscribed.

Please help me.
