Wi-Fi amplifiers, also called Wi-Fi repeaters or expanders Wi-Fi, are electronic devices that allow you to extend the range of the wireless signal Wi-Fi so it can reach areas of shadow, acting both on the strength of the signal and on the stability of the same. Wi-Fi amplifiers support two forms of use, as the main access point or as a point of access Repeater, allowing connection to other Wi-Fi amplifiers as well as Wi-Fi terminals. Features Wi-Fi wireless connections have become the main route of access to the Internet both in households and business environments for its effectiveness to extend the signal, ease of use and installation and comfort that assumes the absence of cables. However, the quality of the signal and the radius of coverage are affected by numerous factors, such as interference, away from the router or older network cards, which can lead to shaded areas where reception is poor. There are several options to improve your Wi-Fi signal, the installation of WiFi amplifiers one of the most effective. Wi-Fi amplifiers are connected to the main router and amplify the signal from its position, reaching in this way a greater coverage. Wi-Fi amplifiers are placed in a location where the connection is stable, halfway between the main router and the place where you want to extend the signal, and increases the same power and stability, avoiding the peaks of power that prevent connecting to the Internet in a stable manner. Wi-Fi amplifiers are generally compatible with 802.11 wireless protocols b and allow doubling the range of the main router, still possible also use several at once to cover a greater extension.

Functioning Wi-Fi amplifiers have two operating modes: primary access (Master Access Point) point: Wi-Fi amplifiers with this setting are directly connected via Ethernet cable to the ADSL modem/router and create a wireless network Wi-Fi different wireless network Wi-Fi of the modem/router ADSL, becoming point of access Principal.En this case we remove the Wi-Fi of the ADSL modem/router to prevent interference signal using the same frequency. This option is appropriate when the ADSL modem/router has a low power or works in the standard 802. 11b instead of 802. 11 g/n standards, that offer a power significantly greater. Access Repeater (Relay Access Point) point: in this mode, WiFi amplifiers are connected to the modem/router ADSL via Wi-Fi or Ethernet cable, acting as repeaters of the ADSL modem/router wireless network, achieving greater coverage by adding both signals.In this case the Wi-Fi amplifiers simultaneously act as remote access (Remote Access Point) point and client Wi-Fi. They are placed at a point within the radius of coverage of the main router or other Wi-Fi amplifiers, half way with respect to the place to the you want to extend the signal.
