WD My Net n900

Hello,
I seem to be loosing bandwidth over my WiFi. I range from 4-19 MBPS. But wired I can get about 28-30. Is there something I can change in the router settings?

The router allows you to change the band and frequency. If this has been already configured differently and you still have the same results then it’s possible for the device to be malfunctioning.
