Describes the functions of broadband routers used by home users.

It is estimated that many family Internet users will encounter a problem of multi-host internet access with a network cable. the most suitable solution to this problem is undoubtedly the purchase of a Broadband Router with a low price and many functions, many products also provide basic firewall functions.

So what functions should a Broadband Router suitable for shared Internet access at home have? In fact, this problem is rarely of interest to some netizens, because everyone thinks that a vro can access the Internet at the same time as long as it can implement multiple machines. Other functions are attached, and it doesn't matter if there are any other functions.

As a matter of fact, most of the current Broadband Router functions are already very powerful, and many functions are indeed very practical for general home users, which can improve the performance of many network applications, learn more about the additional functions provided by the vro, which can improve the network utilization and security.

Next, let's talk about the functions of current home routers. By the way, we will tell you which functions are more practical and which functions are of little significance:

DHCP function:

This function is one of the essential basic functions. It is implemented through a server in a network to provide the corresponding network configuration service, you can provide temporary IP addresses, default gateways, DNS servers, and other network configurations for network terminal devices. This feature is generally enabled by default. If not, you are advised to open it on the management interface, in this way, the computer connected to the vro can access the Internet using the automatically obtained IP settings in network settings, which is very convenient. Of course, DHCP technology also has its disadvantages:

Random IP Address: users' IP addresses are randomly allocated with uncertainty.

Access permission change: if a user's access permission is divided based on an IP address, the access permission varies with the IP address.

Inaccessible: IP addresses obtained through DHCP are uncertain, making it difficult for users to be accessed.

Application continuity: If you use networks continuously between WLAN networks in different network segments, changing the IP address will interrupt the application.

Poor security: external network users pose security threats to the network itself

UPNP function:

Universal plug-and-play (UPnP) is a common architecture for peer-to-peer network connection between PC machines and smart devices or instruments, especially in the home. UPnP is based on Internet standards and technologies such as TCP/IP, HTTP, and XML, so that such devices can automatically connect to and work with each other, so that the network, especially the home network) it is possible for more people.

The UPnP is widely used because it targets home networks, nearby networks, and networks in small businesses and residential buildings. Under the management of network control devices, it supports data communication between any two devices. UPnP does not depend on a specific operating system, programming language, or physical media.

This is not easy to understand, because it requires additional NAT and programming knowledge to be clearly explained, so we can simply understand it in this way, UPNP allows Intranet users to implement the following applications:

Multi-player online games, such as Warcraft and other multiplayer Combat Games)

P2P connections, such as BT downloading)

Real-time communication, such as MSN voice and file transmission)

Remote Assistance to Windows XP)
