Mercusys Wifi Extender Setup

There are many reasons why the 300mbps Mercusys MW300RE is so popular. First of all, its performance is very good for its price. In addition to other extenders, it is very important to have 3 external antennas and to use MIMO technology. This feature significantly increases the speed of the wireless network and spreads the wifi signal to wider areas thanks to its antennas. In addition, with the WPS mode feature available in different brands, you can easily install and position the device by determining the area with the best wifi by using the LED lights.

You can place your Range Extender device by mounting it on the wall where you want the wifi signal to reach. Since it is used with 2.4 Ghz wifi channel setting and has MIMO technology, the MW300RE performs well in terms of coverage and wifi speed. Once you make a connection with the WPS button, there is no need to complete the setup and connect again and again. Unplug it whenever you want, take it wherever you need wifi and plug it in. It is very practical.
