Take an Internet caf router, how to use a router in an Internet caf ?

The router of the Internet café is set with a username, password and IP address, and you can't get in without it! Generally, the identity of the router is admin, the password is empty, the IP address or if you have the above things, it is easy to say, enter the IP address in the IE address bar, enter the username and password in the pop-up dialog box, and enter the settings screen. The router is mainly IP address and MAC filtering, just remove the option!

In addition, you can manage the network with "Jusheng Netmaster" and "P2P Terminator", and you can restrict the Internet access function of a certain computer or all computers! If the Internet café already has a "P2P Terminator", you can install an "Anti-P2P Terminator", and the above software can be found for free on the Internet.

You don't seem to be stating your problem.

Take an Internet café router? The router is a device that can be held directly in your hand.

As for the description of the router, there are many kinds of hardware routes on the market, and there are many soft routes. If you buy a hard router, there are relevant manuals, and you can search for tutorials on the Internet for soft routes.

It is difficult to break through the limit when it is limited by routes.

As for modifying the router, if it is a hard route, it is basically impossible, and you can't even think about it without professional technology.

Here are 4 words for you: don't even think about it.

What if a hard route can be changed directly by bypassing the password?

Is there still security in the world?

First of all. Is it okay for an Internet café to have no routers?

Generally speaking, you can't do without a router, but it's not so absolute. It's okay for an internet café to not have a router. Routing can also be replaced by Layer 3 switches. A Layer 3 switch consists of a switch and a router.

Roughly speaking, routers are used to connect different network structures. For example, connecting the network between the Internet café and the telecom, and separating the intranet of the Internet café from the telecom's WAN, is the most basic function of routing. Therefore, there are generally only one or two routers in a network, which means that there are only one or two networks in this environment.

If you use routing at home, there are usually more than 2 computers to form a small network, and the route is also used to isolate the network between the 2 networks at home and telecommunications, which is also called LAN.

Of course, routing can also be used for packet processing, network management and division of virtual networks, he includes the function of switches, routing technology is more complex, for us ordinary people, as long as we know that it is used to [separate different networks]. This is his basic role.

Here's how to set it up:

1. Do not connect the secondary circuit to the main router first.

2. One end of the network cable is connected to any LAN port of the router, and the other end is connected to the computer.

3. Change the LAN port IP of the login interface through the computer to avoid conflicts with the IP segment of the main router;

4. WAN port Internet access mode selection: dynamic IP connection, enable DHCP server.

5. Wireless settings and keys, save and exit.

6. Connect the network cable from any LAN port of the main router to the WAN port of the wireless router, and the computer can access the Internet at this time.

One of the functions of the router is to connect different networks, and the other is to choose the route to which the information is transmitted. Choosing a smooth and fast shortcut can greatly improve the communication speed, reduce the communication load of the network system, save the network system resources, and improve the smooth rate of the network system, so that the network system can play a greater role.

From the point of view of filtering network traffic, routers function very similarly to switches and bridges. But unlike switches, which work at the physical layer of the network and physically divide network segments, routers use specialized software protocols to logically divide the entire network. For example, a router that supports the IP protocol can divide the network into multiple subnetwork segments, so that only network traffic destined for a specific IP address can pass through the router.

For each received packet, the router recalculates its check value and writes a new physical address. As a result, using routers** and filtering data tends to be slower than switches that only look at the physical address of the packet. However, for those networks with complex structures, the use of routers can improve the overall efficiency of the network.

Another obvious advantage of routers is that they can automatically filter network broadcasts. In general, the entire installation process of adding a router to a network is much more complex than a plug-and-play switch.

Generally speaking, heterogeneous network interconnection and multiple subnet interconnection should be done by routers.

The main dust game of the router is to find the best transmission path for each data frame passing through the router and efficiently transmit that data to the destination site. It can be seen that the strategy of selecting the best path, that is, the routing algorithm, is the key to the router. In order to complete; In this work, the relevant data of various transmission paths is stored in the router - routing table for routing selection; .

The route table contains the flag information of the subnet, the number of routers on the network, and the name of the next router. The path table can be fixed by the system administrator, dynamically modified by the system, automatically adjusted by the router, or controlled by the host.

1 Static path table.

The fixed path table set by the system administrator in advance is called a static path 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.

2 Dynamic path tables.

The dynamic path table is a route 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.

Scheme.

1. The wireless router is used as a switch, and the DHCP service of the Internet café is turned on (this situation is the most).

1. When powered on, use a needle to reach into the reset hole and hold it for 5 seconds to restore the router to factory settings.

2. The computer is connected to the wireless router separately (wired or wireless), and the computer enters the wireless router and makes the following settings:

1. Turn off the DHCP service of the wireless router, otherwise it will conflict with the DHCP of the Internet café.

2. Set the IP address and subnet mask of the LAN port so that the router and the Internet café machine are in the same network segment, and the IP address does not conflict.

3. Exit after saving and restart the router.

3. The Internet café switch is connected to the LAN port of the wireless router with a network cable, so that the router can be used as a switch.

Fourth, now your device can be used normally.

There are other situations, 1. If the Internet café uses a manual IP address, you can also manually set or open the DHCP of the wireless router, but pay attention to setting the DHCP server in the same network segment as the Internet café.

2. The router can also be used as a router, but it is necessary to set the wireless LAN segment address and the Internet café in different network segments, which are also divided into static IP and dynamic IP, and you can choose according to the situation.

Yes? What do you mean.

Multiple computers in Internet cafes need to use switches. There are too few routing ports and few wireless support channels.
