Nowadays, wireless WiFi network is used for almost all devices: laptops, mobile phones, netbooks, PDAs. This technology makes for us more convenient and faster access to the Internet. Many providers now offer WiFi Internet access. In order to use wireless access technology, you need to use a router or access point. Both of these devices use a WiFi channel and are designed to provide radio coverage (AP mode), but, nevertheless, they are fundamentally different. Although the router can operate as an access point and has more features than just an access point. The router mode is determined by its setting. By default, the access point mode is selected in the router and there are many instructions on how to configure the router as an access point.
In addition, using an access point alone cannot protect you against network intrusions. In this case, for protection, you will have to use the capabilities of the firewall on your computer. In the router, you can configure protection against network attacks. Some of the advantages of using an access point include the fact that you do not have to configure port forwarding for torrents and dc. A standard access point provides signal reception in a radius of 200-250 meters, if there are no obstacles in the signal path that reduce the signal strength (concrete walls, iron structures).
If we compare the router and the access point visually, it can be noted that the access point is equipped with only one Ethernet port, and standard routers have five (four LAN ports and one WAN port).
As a rule, the WAN port is separated from the others and a network cable from the provider is connected to it. On the front panel of the router, there are usually light indicators that indicate the connection of a cable to a particular port. In LAN ports, clients of your local network created by the router are connected via twisted pair.
For access points, the DHCP server is disabled by default, and therefore, to connect to it via WiFi or Ethernet, you must assign it a static IP address. Using the Ethernet port, the access point can connect via Static IP or DHCP. You definitely need to know which connection protocol your provider has installed.
