How to extend the wi-fi range of your network with repeater
The repeaters are often the easiest way to extend the range of a Wi-Fi network. They are devices that receive the signal of an existing network, they regenerate and retransmit it in its coverage area. They do not require any special configuration, since their purpose is not to create a new WLAN, but simply exploit an already present network. They also do not have to be connected via Ethernet cable, but only through AC power.
Often also called “wi-fi range extender” or with other similar names, the wi-fi repeaters have a major limitation: having to use the radio equipment for both communicating with the main access point and for extending wireless signal to the client, the available overall wireless bandwidth will be halved.
In the case of an 802.11g wifi network, for example, the theoretical 54 Mbps down to 27 Mbps and, in turn, the actual throughput is halved. These are solutions that improve wireless coverage, but decrease the speed. In addition to the stand-alone devices developed specifically for this purpose, the repeater function can also be performed by a traditional access point, not all access points on the market are able to operate in repeater mode, and this feature is not always well marked in technical specifications of the product. Before to buy an access point or router, check that the repeater mode network is supported.
Install a wi-fi repeater is a simple operation. First, it is important to choose the most appropriate point for the placement of the device: it does not require a wired connection to the network, so you will have a fair amount of freedom in the choice of location. Typically, the wireless repeater is located in an area with coverage limits of the original access point signal, so to maximize the signal range. Pay attentio to do not exceed: the signal received by the repeater must still be of good quality to avoid reducing the speed of connection.
