What does a wireless router do? Let’s Have a Look

A router is extremely important because you would not be able to have more than one device using your Internet without it. A router can either be wired or wireless. You can use both wired or wireless router. The wireless router gives more flexibility of movement around your home. So you should know what does a wireless router do?

 

  1. Routers connect a modem to other devices to allow communication between those devices and the Internet. Routers usually feature several network ports to connect numerous devices to the Internet simultaneously.
  2. A router connects physically through a network cable, to the modem via Internet or WAN and then physically via a network cable. A wireless router can connect through various wireless standards to devices that also support the particular standard used.
  3. When you make a request for data from a website that information is wrapped up in many self-contained envelopes which are called “packets”. These packets contain the data and include the name address of the recipient.
  4. When the packet is created the label gets a return address and that is your IP address. If you have a static IP address it will assign to your network an IP address. The IP address is allocated your router links up to the ISP network.
  5. Home routers route data between networks in the best possible way. They also have to create a local network for your device. They do this because when you get an IP address from your ISP, that IP address is for your network, not for every device on your network. Router face problem because the only internet understands your network IP address which means that it must readdress the packets it receives from your devices with your network IP address and then remember to put the correct device address back on when it receives it the packet back.
  6. The next issue with the packet is that it faces the problem when it does not have a map address of how to get there. Routers take an important role to fix this problem. Routers take the data, read the address name, using a router table and send it in the right direction using the fastest route.
