What Does A Wireless Router Do
(Last Updated On: December 15, 2017)

As we have previously explained comprehensively that what type of work does a wireless do? The next thing we thought was needed for our readers to know was the technical details of how the tasks are performed by the Wireless Router in your home or office. To recall what the wireless router did, wireless router basically performs tasks of multiple devices as in the old days we had modems, switches and routers connecting our devices to the Internet. The wireless routers of today have modem and switch capabilities integrated into it.

The wireless routers we see today in our homes and offices not route the data to the designated device but also modulate and demodulate the data and apart from that the local network that we have within our homes or offices also communicates with the help of wireless routers as they have built in switch mechanism which allows for this to happen. Now these are the basic features of today’s wireless router, the latest technology has allowed for the wireless routers to have capability to handle dedicated data lines to each connected device, the connected device number can be upwards of 20 to 25 simultaneously depending on the specifications of the wireless router. So in this publication we are going to get into the technical features of the wireless router’s functions. So let’s get into it.

What Does a Wireless Router Do?

IP Management

The ISPs (Internet Service Providers) only provide it’s customers with a single IP address to connect to the internet. If you have multiple devices wanting to use the Internet that single IP address will do you no good. This is where wireless router comes in. The wireless router working with a single IP address and multiple devices connected to it, make sure that right information is delivered to the right device by distinguishing between the devices connected to it. Without this functionality in a wireless router it would be impossible for multiple devices to browse the Internet using a single IP address.

NAT (Network Address Translation)

This task is also very similar to that of the IP management but the only difference between the two is that the NAT modifies data packet headers to identify which data belongs to which device, going in and out of your local network. The modification in the header of the data basically points out which data packet is to be delivered to which device and so on.

Dynamic Host Configuration

No matter how many devices enter your local network and share information in that network, each device has to be allotted a unique address within the network to make the identification easier. The host configuration has to be done every time a new device connects to the network. Now this task is automatically done by the wireless router and doesn’t require human interaction to do so.


A firewall is basically a secure door between your devices (your network) and the Internet. A firewall basically rejects anything that is not a part of your network’s data transfer and is suspicious in any kind. The firewall capability is integrated within the wireless router to filter out any harmful or suspicious data packets and reject their entry into your local network.

These were the main tasks a wireless router performs in a network apart from the basic ones. We hope you find this publication useful. Be sure to check out our reviewed wireless routers, just follow the link.
