Routers WiFi

The Wi-Fi, often called Wi-Fi modems, routers are electronic devices that allow Internet access through a wireless access point Wi-Fi to the machines on a wireless local area network WLAN (Wireless LAN, wireless local area network). All telephone networks, whether fixed, mobile, cable or radio, have Wi-Fi routers to connect to the Internet and share the connection transparently with other computers that have Wi-Fi connectivity. Features Wi-Fi routers and Wi-Fi modems expressions are generic terms that are used interchangeably to refer to those teams that allow access to the Internet to a local network wireless Wi-Fi. Let’s look at some important features: configuration: normally the Wi-Fi routers are configured through web interface. An accessible web page on the IP allows setting all the options of the computer. Security: implement security on the Wi-Fi routers is important mainly for two reasons: protecting the use of bandwidth by strangers and prevent access intrusion to the local network machines. There are several systems to protect the access, being the most common set a WEP password or enable filtering by MAC, although all the security methods can be violated by persons with sufficient knowledge. Features: Wi-Fi routers are devices that perform several duties at the same time, since they act as a gateway, router, modem, switch and wireless access point.

Additional functions: often have network advanced features such as DHCP server, firewall, DNS server, filtering of packages or encryption. Storage unit: some models incorporate features that allows it to be used as a unit of shared storage accessible from any computer on the network, as I drive hard internal, USB port for connecting external hard drives or FTP file server. Types look at the main types of Wi-Fi, according to the type of telephone network routers give you access: fixed telephone network: to access the Internet through a telephone line fixed ADSL Wi-Fi ADSL routers are used. Mobile network: to connect to the Internet through a cellular network (GPRS, UMTS, HSPA, EVDO, WiMax, 3 G) have two options, the Wi-Fi 3 G routers, an external modem that has Wi-Fi connectivity, and the 3 G USB modem equipped with a basis Wi-Fi that implements the functionality of the WLAN router. In both cases requires a SIM card to identify itself to the telephone operator. Another possibility for mobile Internet access is to leverage the many mobile phones to serve as a Wi-Fi routers for other teams, being indispensable requirement for this that both have Wi-Fi connectivity. Telephone cable network: some Wi-Fi routers called modem are used to access the Internet through an infrastructure of television by cable. Telephone radio network: WiMAX router are used to get Internet connection over a telephone network by radio.
