4. Find Optimal Position

The purpose of a Wi-Fi range extender is to expand the Wi-Fi coverage in your home, by capturing the signal from your wireless router and expanding it further. To accomplish this, you need to place the range extender within the existing coverage area of your wireless router. However, to maintain an excellent wireless signal for your Wi-Fi devices, the range extender needs to be positioned within optimal distance from the wireless router. Here's how to accomplish this:

1. Plug your range extender into an available power outlet in the area you'd like to expand your home's Wi-Fi coverage to.
2. Check the circular status light on the front of the range extender:
   

1. Solid Blue

1. Indicates an excellent wireless signal.
2. Solid Red

1. Indicates a weak wireless signal.
2. If the status indicator light shows a weak signal, plug the range extender into a power outlet that's a bit closer to your wireless router.
   

1. Repeat this process until the range extender indicates an excellent signal.
