3-Instructions and configuration Manual of the Melon R658 router:

In this installation example, the source WiFi signal is connected to the long distance via the 36dbi Melon N4000 Panel antenna, which connects to the R658 USB cable and the R658 redistributes the Internet connection to multiple users or WiFi clients (computers of Desk, laptops, tablets, TV or WiFi cameras).

In this example to connect to an access point up to 2 kilometers away, we use an external high gain antenna N4000 with WiFi adapter RT3070. The antenna mounted to the WiFi adapter is placed outside the window and connects with a USB cable to the R658 device installed inside D It house or inside a plastic box that protects it from rain.
The R36 is a wireless local access point that repeats the desired signal to the house. In this way any computer with wireless capacity or tablet under any operating system will be able to take advantage of the high gain external antenna. And all this without having to install any software (driver or utility) on your computer or tablet.

4-Other Router similar to R658

In the market there are two other router similar to the R658 that meet the same function with very few differences in power and compatibility. Here we expose the opinions on the two most prominent repeaters and their advantages in relation to the r658.

4.1-alpha Network R36 Router

This router in its original version gave problems of cuts and falls of speed in the connection that the Melon R658 does not have. But Alpha has greatly improved the firmware on the 2019 with the new Alfa R36 2.32 that allows it to be compatible with WiFi RTL8187 chip antennas, which do not work with the R658. The model of Alfa is a little more expensive than melon and in our opinion as a repeater is better the melon R658, but the Alfa has other very interesting functions as a 3g Modem repeater.

4.2-OpenWRT Router SC-WE1626

This Openwrt SC-WE1626 router is ideal for use as a WIFI repeater. Its firmware improves the R658 as it is also in Spanish language as well as English, and is easier to configure than the R658. It also carries drivers for some models of WiFi antennas that does not include Melon as MEDIATEK RALINK RT3070 RT3072 RT73xx RT5370 rtl8187 rtl8188.

The main advantage of the SC-WE1626 model is that it comes with the enhanced version of LEDE OPENWRT firmware and that the WiFi broadcast power has more coverage with its four antennas.
