A local router which is attached to a Local Area Network or Wireless Local Area Network acts as the local postman by determining the physical MAC Address of a device so that it can deliver packets to the correct computer device.
In order to connect to the Internet we normally need a modem that runs the same protocols as the Service Provider Access Network. In most cases we will be using either an ADSL Modem or a Cable modem depending on who our service provider is. short term internet access
A wireless Router will normally combine the functions of a modem, a router and a wireless access point, and provide not only wired connectivity to local devices by means of an Ethernet cable, but also provide the option of connecting to local devices by means of a wireless technology specified in the IEEE 802.11 Wireless standard. The IEEE 802.11g standard allows for local wireless connectivity at 54Mbps within the 2.4 GHz ISM frequency bands. The IEEE 802.11n standard was ratified in 2009 and provides for enhanced data rates up to 300 or even 600Mbps and incorporates the MIMO (Multiple Input Multiple Output) technology which requires the use of additional antennas. The channel width is also doubled from 20Mhz wide channels used with previous versions of the standard to 40Mhz. Routers running the 802.11n standard with MIMO are normally a little more expensive due to the cost of the additional antennas.
The home Wireless router will also act as a DHCP (Dynamic Host Configuration Protocol) Server, so that local IP Addresses can be automatically served up to local computer devices, doing away with the need to manually configure IP parameters on each and 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. This means we can all use the same local IP Addresses on our LAN or WLAN to communicate locally, but use the Global IP Address supplied by our Service Provider when accessing the Internet. The router translates from local to global on the way out and the reverse as packets are routed towards the local network. outdoor event wifi
Any network needs a degree of security, particularly when connected to the Public Internet, otherwise anyone globally could have access to your network. The router will provide this security by having a built-in Firewall function. Wireless networks have additional security issues because of the fact that anyone within range of your wireless network, who has a wireless access point or device could join the network and therefore eavesdrop on data conversations, or worse still access a computer device and steal or corrupt information. For this reason a number of Wireless security protocols have been developed 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 length to protect the data as it traverses the wireless lan. WEP keys can easily be broken by someone determined enough to do it and programs are freely available on the Internet for this purpose. For most home users WEP may be sufficient, but as you don't necessarily know who your neighbours are and their intentions, it is better to protect your local wireless network with a more advanced security protocol. WPA (Wi-Fi Protected Access) uses much stronger encryption than WEP and should be used in preference to WEP when necessary. It is important to note that most wireless routers come packaged with wireless security turned off, so it is up to the consumer to determine the level of security required and to configure the parameters when originally setting up your WLAN. If you are not technically minded then find a friend of relative that has some knowledge and choose the strongest protection available on the device, which will normally be WPA.

Such devices are used to connect computers and other smart devices like you phone or tablet with the data network.
So, to connect your computer or smart phone to the internet, these wireless routers can be used and the device that is connecting to the internet with the help of router does not need to pay for any subscription.
A wireless router generally has a range of 100 meters; hence any device capable of accepting wireless data signals can do so if it is in the range.
Let’s see which ones.Home Use – These type of routers serve a small area and allows a user to connect his laptop within network range inside a house held as long as the laptop which is place in the wireless range.
Office Use – As the name type suggest, it is used in offices or large workspaces.
Here the internet can only be accessed if the LAN or Local Area Connection cable is connected to the computer or laptop.How does a wireless router function?A wireless router is based on plugging base set method, which is connected to a user’s internet connection.
The presence of a Wi-Fi router has become almost invariable.
Using the virtual router redundancy protocol (VRRP), it becomes active when any of the primaries, physical routers are disabled.
You might have other people piggyback riding through your router, which may reduce your speed at the same time, decreasing your data packets and increasing your charges.
Average home routers do not have malware detection or prevention software, hence resetting your router is your best bet against such an attack.
The router takes some time to resume its functions after power is restored.
Ensures that fresh settings are installed for the router, usually used when an administrator has forgotten their password.
