The following section of this article on Wi-fi routers will include information on how a wireless router works.
How does a wireless router work?
The wireless router will not require the usage of cable wires. It will require a simple set up consisting of a box like device which is actually a radio transmitter and receiver, responsible for the exchange of radio waves which would in turn help in the supply of data in the connected devices.
The maximum range supported by the device is that of about 90 meters or roughly 300 ft. So, you can very well understand that the Wi-Fi wireless router provides you with a protected area network, limited within a small area.
If you own a pc which supports wireless access to wi-fi, you simply have to update a few software on your pc and connect it to the router. If you have any of the older models, you are likely to be provided with a wireless adapter card which is to be installed in your device.
The other gadgets such as iPads, tablets, android phones would not require any additional changes since they are already adaptable to wireless connections.
The wireless router will provide the connected devices with a unique number, referred to as the IP address. All the connected devices will be able to related to this address or rather the location. The router creates an invisible cloud of wireless internet connectivity. It creates a kind of LAN Network within your house or office.
Any gadget within the close proximity or rather within the range (called the Wi-fi Hotspot) of the wireless router will be supplied with an internet connection. You can connect as many devices as you want. However, the speed might fluctuate.
You will be supplied with a power adaptor along with the wireless router device. This will enable you to place your device on a wall. Ethernet cable will also be provided so that you can connect all your computers or laptops or any other device which does not support the wireless connection.
Modem V/s Router
A lot of us think that a modem and a router are the same thing, but they are not and both are magnificently important. In case you do not have a modem, you will not have the access to the internet at all.
To be precise, a modem plays the role of bringing in the internet connection to your home, which in turn is directed into your devices. Modem refers to ‘modulator-demodulator’, which means that a modem is responsible for demodulating the incoming analog data from the internet coming into a computer, turning them into digital signals.

A computer reads the digital signals and then the modem modulates the digital signals into analog signals which are received and processed by the internet. Thus, the modem is responsible for maintaining a dedicated connection with the internet service provider. Therefore, you have to have a modem.
The role of a router comes into play after this. The router has nothing to do with bringing in the internet connection. It is just there to pass down the internet connection from your modem to all the other devices in your house or office.
All the devices connected to the router will basically share the same internet connection. The process of how it is done has already been clarified in the previous sections of this article.
Thus, the question shouldn’t be Modem or Router? Rather, both Modem and Router are required for creating a home network. But if you are just concerned with having internet connection on just one device, you can go for just the modem which will directly give your device the access to the internet. However, if you desire to have internet connection on multiple gadgets, it is better to go with a Router.
