Why use a wireless router

Why use a wireless router

Number of households in the UK, Europe and the United States and an Internet connection, and most cases are devices called wireless router to connect at least one piece of equipment. In many cases, the wireless router is used to connect the different devices supported by the local WLAN.

Before describing the particular wireless router, is to describe the role of routers in the data network. IP router opportunity to read the logic of the package and decide which network or a small network to promote the necessary packages. An easy way to check is to compare the router after the isolation post office where the letter or zip code to see what areas of the country goes to the letter. In Britain, the first part of the postcode to determine the total area like London or Manchester, and elsewhere in determining the actual street or highway. IP address, subnet mask, and when it is almost the same, but the geography, the router can make a decision on a specific area network.

The local router is connected to the LAN or Wireless LAN acts as the local postman to mention the MAC address of the physical device as the device that can provide a good computer bag.

Connect to the Internet, you generally need a modem to run the same protocol and the access provider service networks. In most cases, is used either cable modem or DSL service up to us.

Wireless router usually combine the functions of a modem, access point and wireless router, not just wireless connectivity to local devices via ethernet cable, but also offers opportunities to connect local devices with wireless technology and reflected in the standard IEEE 802.11 wireless network. IEEE 802.11 standard allows connection of 54 Mbps Wireless LAN in the frequency band 2.4 GHz ISM. IEEE 802.11n standard was established in 2012 and provides data rates up to 300 Mbps or 600 levels, including the IMO technology (Multiple Input Multiple Output of Wales), which requires the use of additional antenna . The channel width is 20MHz wide dual route used by previous versions of the standard and 40MHz. 802.11n router with an average size of the IMO to implement a bit more expensive because the cost of the additional antenna.

Home wireless routers acts as a DHCP (Dynamic Host Configuration Protocol), the local IP address will be sent directly to the hardware inside your computer, eliminating the need to manually configure IP parameters for each unit built. Another wireless router running the protocol and NAT (Network Address Translation), which means that the global address IP routing, routable IP addresses needed on the web. This means that all use the same IP address on the LAN or WLAN to communicate in the country, but using the IP address provided by the global service provider, when we go online. Interpretation of previous international and local authorities through the outer casing of the router and local network.

Any network requires a reliable contact, especially when it is published, if not, no one can get from the international network. The routers offer security features and built-in firewall. wireless networks, in addition to security because someone writes on the network, wireless access to wireless devices, or to participate in a data network and then listen to conversations, or access the. Bad and the theft of a computer or device corruption of information is for this reason, the wireless security protocol that many is developed to protect the WLAN.

first wireless security protocol WEP (Wireless Equivalent Privacy) encryption and authentication using the public key of 64 or 128 bits in length to protect wireless data as a cross. WEP keys are easily broken with enough interest to do this with free programs available online for this. For most home users, WEP is sufficient, but you never know who your neighbors and their motives, it is best to protect the security of wireless LAN protocol is higher. WPA (Wi-Fi Protected Access) is stronger than WEP encryption used by more than WEP should be used when necessary. Importantly, most come packaged with wireless security disabled, so it's up to users to determine the level of security required to set the standards originally set up the WLAN. If you are not technically minded and looking for a relationship with some information and choice of power protection available on the device, commonly AWG. suntingan
