The Wavlink AC750 setup is a worry-free job as one just has to follow the very simple setup procedure. If your device supports WPS, do consider yourself fortunate and intelligent. It's just the simplest way of installing the extender. But just make sure the router has this button also. So if your router has a WPS, press the WPS button on the router first. After about a minute, release the WPS button on the router, and then press the WPS button on the extender. Check the light indicators on the device above; if a red light is shown, it means that the extender is not connected. However, wait a little while as it sometimes takes longer for an extender to connect. Sometimes the appropriate lights do not come on due to the circuit and connection delays.
