The majority of households in the UK, Europe and the US will have a very connection to the Internet, and in most cases will have a device known as a Wireless Router to offer that connectivity for a minimum of 1 computer device. In most cases the Wireless Router will likely be employed to connect multiple devices from your local WLAN towards the Public Internet.

Before we specifically describe a Wireless Router, it is probably best to explain the role of the Router inside a data network. A Router's role is to read the logical IP Address on packets and see which network or sub network those packets need to become delivered to. A simple way to check at the router would be to compare it to your postal sorting office where letters get their post codes or zip codes checked to discover which area of the country the letter is destined for. In the UK, the first part of the postal code determines the area including an area of London or Manchester, and the next part determines a genuine street or road. An IP Address, when coupled having a network mask does almost a similar thing, but instead of the Geographical area, the router is capable of determine a particular area of an network.

A local router which can be attached to your Neighborhood Network or Wireless Specific Geographic Area Network acts since the local postman by determining the physical MAC Address of an device so which it can deliver packets towards the correct computer device.

In order for connecting for the Internet we normally have to have a modem that runs a similar protocols because the Company Access Network. In most cases we is going to be using either an ADSL Modem or even a Cable modem depending on who our supplier is.

A wireless Router will normally combine the functions of the modem, a router as well as a wireless access point, and offer not only wired connectivity to local devices by means of the Ethernet cable, but also give you the use of connecting to local devices by means of an wireless technology specified within the IEEE 802.11 Wireless standard. The IEEE 802.11g standard allows for local wireless connectivity at 54Mbps inside 2.4Ghz ISM frequency bands. The IEEE 802.11n standard was ratified in 2009 and provides for enhanced data rates approximately 300 and even 600Mbps and incorporates the MIMO ( Multiple Input Multiple Output) technology which necessitates use of additional antennas. The channel width can also be doubled from 20Mhz wide channels used in combination with previous versions of the standard to 40Mhz. Routers running the 802.11n standard with MIMO are usually a little more costly due on the cost of the additional antennas.

The home Wireless router may also act like a DHCP (Dynamic Host Configuration Protocol) Server, so that local IP Addresses could be automatically served as much as local computer devices, doing away with all the must manually configure IP parameters on each an every local device. Another protocol running on the wireless router with be NAT (Network Address Translation), which translates locally routable IP Addresses to Globally routable IP Addresses needed on the Internet. What this means is we could all use a similar local IP Addresses on our LAN or WLAN to convey locally, but utilize the Global Ip supplied by our Company when accessing the Internet. The router translates from near global on the way to stop it along with the reverse as packets are routed for the local network.

Any network needs a degree of security, particularly if connected for the Public Internet, otherwise anyone globally would have access for a network. The router provides this security by having a built-in Firewall function. Wireless networks have additional security issues because from the undeniable fact that anyone within range of one's wireless network, who features a wireless access point or device could join the network and to the reason eavesdrop on data conversations, or worse still access a pc oral appliance steal or corrupt information. For that reason a number of Wireless security protocols happen to be designed to protect the WLAN.

The first wireless security protocol was WEP (Wireless Equivalent Privacy) which uses an Authentication and Encryption key normally of 64 or 128 bits in total to safeguard the data as it traverses the wireless lan. WEP keys can easily be broken by someone determined enough to perform it and programs are freely available on the Internet with this purpose. For most home users WEP may be sufficient, but because you don't necessarily know who your neighbours are along with their intentions, it's easier to protect any local wireless network with a more advanced security protocol. WPA (Wi-Fi Protected Access) uses much stronger encryption than WEP and really should be utilized in preference to WEP when necessary. It is essential to notice that a lot of wireless routers come packaged with wireless security turned off, so it really is up on the consumer to discover the degree of security required and configure the parameters when originally setting increase WLAN. In the event you aren't technically minded arehorrified to find that a pal of relative which has some knowledge and judge the strongest protection available around the device, that will normally be WPA.
