Wireless Network – Router Vs Access Point


When designing wireless networks, you can ask what is the difference between the router and the access point. The router needs to think of multiple servers as it performs many functions like a server. The access point provides only a portal for a wireless client that is connected to the existing local network.

Routers can perform many functions . Routers can connect multiple WLANs like a traffic police officer. Routers also work as a DHCP server. The DHCP server assigns a dynamic IP address to the computer each time the computer is started. If you do not have a DHCP server, you must assign a computer on each network with a permanent IP address.

As I mentioned before the router can function as a traffic police officer. You can use a router to forward the port to some computers on the LAN. For example, you can control all internet traffic that searches for the number of port on the game server for a particular computer on your computer.

The ability to connect multiple computers to a computer is one of the main features of the router. We assign a WAN IP address to the router from the ISP. This IP address is called a public IP address that everyone can see on the Internet. Because multiple computers are connected to the router, the router uses NAT protocol {Network address translation} NAT assigns the computers that are behind the IP address of the routers, their private IP addresses. NAT acts as a firewall because computers on the Internet in theory do not even see computers. You will only see the router's IP address. NAT blocks traffic to access your computer, but will not block trojans from leaving the Internet. Therefore, I suggest installing a firewall on LAN computers.

The role of the access point at a LAN to allow the wireless user to log in. The more people enter the door simultaneously, the slower the number of people. 802.11b access points are said to provide a temporary upload speed, but the actual speed is about 5MPS. The 802.11g has a resolution of 54 megapixels and the actual transfer rate is 20 MBps. Access points have the same security features as the router, such as WEP, WPA, 8021x, and TKPI, but do not have a router, such as a router. Access points do not have NAT, which would give you an unnecessary layer for your network. To keep simple access points, just simulate the laptop's connection to a wall port and that's it. The router uses the network boundaries to decide on traffic cops, who can come and block those who want to keep it out.
