Can anyone tell me the purpose of the wireless router, the details of the points, the specific point

Let me make it simple: unlimited routing and routing are all for Internet access, but why should there be wireless and wired? The advantage of wireless is that you can surf the Internet without plugging in a network cable, which saves you the trouble of wiring and keeps it beautiful. Nowhere is it most noticeable in an office full of computers.

Because it is wireless, you don't have to worry about whether the network cable is long enough, as long as it is within the signal range, you can move the computer at will, which is very convenient.

Because it is wireless, it is not limited by the interface, as long as you have a wireless network card, you can connect to the wireless router, unlike the ordinary router with only 4 LAN ports, this feature is obvious in public places, such as airports, hot spots in cafes. You go to turn on the wireless connection to dial on the line, no need to call the staff to pull the line for you (called the estimated no).。。

A wireless router is all about replacing your solid network cable with wireless.

You can access the Internet through the wireless network card of the notebook, the wireless function of the PSP, and the devices that support WLAN.

Before, you had to plug in a thick network cable...

Wireless broadband router + wireless network card, many families use it like this. For more details, you also see:

Connect the network cable to the router, and then connect the router to the desktop, open the browser, and set it according to the manual.

To explain the concept of a router, you must first know what a route is. The so-called "routing" refers to the behavior and action of transmitting data from one place to another, and the router is the machine that performs this behavior and action, its English name is router, which is a network device that connects multiple networks or network segments, and it can "translate" the data information between different networks or network segments, so that they can "read" each other's data, thus forming a larger network.

To put it simply, routers have the following main functions:

First, network interconnection, routers support a variety of LAN and WAN interfaces, mainly used to interconnect LAN and WAN, to achieve different networks to communicate with each other;

second, data processing, which provides functions including packet filtering, packing**, priority, multiplexing, encryption, compression, and firewall;

Third, network management, routers provide functions including configuration management, performance management, fault tolerance management, and traffic control.

In order to complete the work of "routing", the relevant data of various transmission paths is saved in the router, and the routing table is used for route selection. The route table stores the flag information of the subnet, the number of routers on the network, and the name of the next router. The routing table can be fixed by the system administrator, dynamically modified by the system, automatically adjusted by the router, or controlled by the host.

There are two concepts involved in the name of an address in a router: a static routing table and a dynamic routing table. The fixed routing table set by the system administrator in advance is called static routing table, which is generally pre-set according to the configuration of the network when the system is installed, and it will not change with the change of the network structure in the future.

A dynamic routing table is a routing table that is automatically adjusted by the router according to the operation of the network system. Based on the functions provided by the routing protocol, the router automatically learns and memorizes network conditions, and automatically calculates the best path for data transmission when needed.

Now let's take a look at how the router plays its role in routing and data in the network environment as shown in the figure. Now suppose that when a user A1 in network A wants to send a request signal to user C3 in network C, the signal transmission steps are as follows:

Step 1: User A1 will send the address C3 of the destination user C3 together with the data information to all nodes in the same network in the form of a data frame through the hub or switch in the form of broadcasting, when the router port A5 detects this address, the analysis knows that the destination node is not the network segment, and needs to route **, so the data frame is received.

Step 2: After port A5 of the router receives the data frame of user A1, it takes out the IP address of user C3 from the header and calculates the best path to user C3 based on the routing table. Because the network ID number and route of C3 are known from the analysis? f

There is a router, and there is no need for a computer to dial the number! It looks like you won't be using a router or can't set it up. Learn how to use the router's settings, and it will take care of your dialing.

First of all, with the BAI router you have electricity.

Du brain can not use broadband dialing to zhi Internet,Because the routing dao can help you dial the number,Your computer only needs to be connected to the subordinate router to automatically go online,Secondly,The wireless router is one more wireless ** function,You can send and receive your network wirelessly,Use the wireless of the notebook、The wifi of the mobile phone searches for your wireless router signal,And connect,You can go to the Internet wireless,Get rid of the shackles of the network cable。

The wireless router is to steal the network, and within the range of other people's network, you can use other people's network. The scope is not large, though.

Wireless means that you can access the Internet through the device without network cables and interfaces.

A wireless router is a device that converts the broadband signal from the cat into a wireless form.

A wireless router is a router that is used for users to surf the Internet and has a wireless coverage function.

A wireless router can be seen as a device that sends broadband network signals from the wall of your home to nearby wireless network devices (laptops, Wi-Fi-enabled mobile phones, tablets, and all Wi-Fi enabled devices) through the antenna.

Popular wireless routers on the market generally support four access modes: dedicated line XDSL cable, dynamic XDSL, and PPTP, and it also has some other network management functions, such as DHCP service, NAT firewall, MAC address filtering, dynamic domain name and other functions.

Wireless routers can be wired, and general wireless routers have 4 wired network ports;

The wireless router can be connected to the desktop type, provided that the desktop computer is equipped with a wireless network card.

In addition, if you are still unclear, you can find someone to install it, generally there are such teams in big cities, such as Hongtian Computer 010-5166-0335 in Beijing, which is a good company to install wireless routers.

The solution is limited, and the laptop does not need a network card.

It can be connected to a desktop computer and requires a wireless network card.

The purpose of the router is as follows: 1. It can be used as a DHCP server, and it can be dynamically allocated: it can do NAT conversion to convert private network and public network IP.

3: It can communicate with the network of different network segments. 4:

Some routers can double as a filtering function to protect against some virus attacks.

A router can dial up instead of a computer. It can realize one broadband for multiple computers.
