The use of routers to routers, how to use routers as converters

I don't know what you mean by the network cable is the landlord's? It's really hard for you.

There are two situations:

One, is the original ** line:

First of all, there must be one who can access the Internet, generally through the "cat" to connect to telecommunications or Netcom, so that a machine can access the Internet.

Then connect the router to let both devices access the Internet. Refer to the router manual for the method.

In addition, you should also prepare three network cables (normal regular network cables), one long and two short, respectively: cat-router, router-computer, router-computer.

Second, it is a network cable that can already access the Internet.

This must have been picked up by the landlord's router. In this way, you can try to ask the landlord to see if the router still has an interface, and you can use the network cable to pull one for your other machine (generally the router can have 4 ports, and your router is also saved).

If you don't want to ask, it's complicated, use the line from the landlord to enter the WAN port, and connect the LAN port to your two computers. Set it as follows:

To make sure that the IP addresses of your router and the landlord's two routers cannot be the same network segment, if the two IPs are in the same network segment, first use your own computer to connect the B route, and then enter it in the address bar If it is the SOHO route of the northern network, it is , of course, the specific parameters are written behind the router to see for yourself) The setting method is as follows:

1. In the network parameters LAN port settings, change the IP to or in short, it is not duplicated with the IP segment of route A.

2. Select WAN port connection type in WAN port settings for network parameters: static IP;

Gateway: DNS: Each region will be different, and you can see how much you have; The method is to connect the network cable to your computer first, and then call up cmd and enter ipconfig in it -all and you will see this value in it).

Route A is set up in the most basic way (using dynamic DHCP).

After this is set up, your computer can generally connect to the LAN port of the B route, and you can access the Internet.

If you can't access the Internet yet, you can set up the DHCP of Route B as follows:

DHCP Server DHCP Service.

DHCP Server: Enabled.

Gateway: (Optional).

Default domain name: (Optional).

Primary DNS server: (Optional).

Alternate DNS server: (Optional).

After restarting Route B, your computer should be able to surf the Internet normally;

With the router, just follow the steps in the manual. The instructions are clearer than anyone else can tell you in this.

1) Router A + Switch B--- Expansion port is recommended.

The LAN port of switch B (any) is connected to the LAN port of router A (any), and the other ports of switch B are directly connected to the network interface of the computer.

2) Router A + Router B

Method: Router B only uses the LAN port and does not use the WAN port, which is equivalent to a 4-port switch. The LAN port of Router A is connected to the LAN port of Router B. Router B disables the DHCP function.

Method: Router B connects to the WAN port of Router A with the LAN port, then you need to log in to Router B, and set the WAN port to dynamic IP or fixed IP address.

The difference between methods and methods:

If used, then all computers that go online through Router B are visible to the administrator of Router A, and all computers that go online through Router A and Router B are in one local area network.

If you use this method, then the computer that accesses the Internet through Router A and the computer that accesses the Internet through Router B are not in the same LAN. The computers that access the Internet through Router B are invisible to the manager of Router A, and Router A can only see that Router B is connected to the network, and it is impossible to know and manage how many computers are connected behind Router B.

If you want to steal someone else's network cable to connect to two or three computers, the best way to choose the access method is to choose the best access method.

Added: Router B needs to change the default management address, such as changing to the same network segment) or different network segments) to avoid conflicts caused by the same IP address of the two routers, and disable the DHCP function as necessary.

Change your routing IP to the incoming route, not the same as your landlord's routing IP.

Turn DHCP off again.

Then all the wires are connected to the LAN port.

If you use the landlord's network cable, is the IP address obtained automatically or manually set? If it is obtained automatically, you click Start-Run, enter cmd, enter ipconfig all in the pop-up box, check the IP address, and then configure this IP to the WAN port of the router.

1. Use a network cable to connect the LAN port of the secondary router and the LAN port of the main router, turn off the DHCP service of the secondary router, and <>

2. And set the IP address of the secondary router Huijixiao.

If the IP address of the primary router is different from the same network segment as the primary router, for example, the IP address of the primary router can be set to.

3. The main router and the secondary router belong to the same network segment and the same LAN, and the terminals connected to the main and secondary routers can access each other. Compared with the routing mode, the switching mode has a small network load and high data efficiency.

4. The router is used as a switch, and does not include the wireless function that will affect the router, no matter which router's wifi is connected to the mobile phone or laptop, it is equivalent to connecting to the LAN port of the router, and all wired and wireless devices can access each other. Remember to set the WiFi password on your router.

There are two connection methods, which are wired and wireless.

Wireless bridging is to connect two wireless routers wirelessly; After the wireless bridging of the two wireless routers is successful, the wireless wifi name can be unified to achieve wireless roaming.

In addition, we can also use a network cable to connect two wireless routers, and there are two ways to connect the two routers with a network cable: set up a secondary router and set up a wireless AP (switch).

Wireless bridging is two wireless routers that are connected wirelessly without the use of network cables. Therefore, it is more convenient and flexible in deployment, and gets rid of the trouble of pulling network cables; In addition, after wireless bridging, the wifi name and wifi password on the two wireless routers can be set to be exactly the same, that is, wireless roaming can be realized after wireless bridging.

However, it is also because of wireless bridging that two routers are connected wirelessly; So, in terms of network stability, transmission speed, etc. Compared with the way of connecting two routers with wires, there is a certain gap.

The way to connect two routers with network cables has great advantages over wireless bridging in terms of network stability and transmission speed. Moreover, the distance between the two wireless routers cannot be compared with the wireless bridging method.

The disadvantage is that you need to deploy network cables, which is very troublesome; And if the distance between the two routers is tens of meters, you need to spend dozens of dollars more to buy a network cable. In addition, after connecting the two routers with network cables, the wifi signal on the two routers cannot achieve wireless roaming; That is, the wifi name and password on both routers cannot be the same.

Switches are generally used for LAN connections, switches are bridges, are devices at the data link layer, and some switches can also realize Layer 3 switching. The router is used for the connection between wans and wans, which can solve the ** packet between networks of the opposite sex and act on the network layer.

They simply accept input packets from one line and then send them to the other line**.

A converter is a device that converts one signal into another. A signal is the form or carrier in which information exists. In the automatic instrumentation equipment and automatic control system, one signal is often converted into another signal model after comparison with the standard quantity or reference quantity, and the two types of instruments are connected, so the converter is often the intermediate link between the two instruments (or devices) of Qingyan.

A router (also known as a pathfinder) is a computer network device that can transmit data packets to destinations through a network (selecting the route of data summoning and transmission), a process called routing. A router is a device that connects two or more separate networks, and routing works at the third layer of the OS model, that is, the network layer, such as the Internet Protocol (NTEMNePER) (IP) layer.

Replacing the router yourself can be done from: replacing it with a new power adapter; Plug in the network cable; Set the working status and password of the router, operate in three steps, connect to the new router Wi-Fi network and you can surf the Internet.

1. Replace the power adapter with a new one.

Unplug the old router power adapter and network cable, and replace it with a new router power adapter.

2. Plug in the network cable.

Connect the network port 1 of the home gateway device or use the network cable to connect the branches to the WAN port of the router, note: The network port of the home gateway device is connected to the TV set-top box.

<>3. Set the working status and password.

Use the management address provided on the label on the back of the router to enter the router management interface to configure the working status of the router and the wireless network name and password, and connect to the new router Wi-Fi network to access the Internet.

Hardware connection to ensure that the new and old routers are powered on, and the network cable connects the WAN ports of the old and new routers.

Software connection, open the phone settings, connect to the wireless network; After the connection is successful, the page will automatically jump to the settings page, if not, please manually open the Tongtong mobile phone browser, access, select "One step to change", and follow the prompts to complete the setting; After completing the setup, if the Wi-Fi wireless connection is disconnected, reconnect with the newly set Wi-Fi name and password. Connect the new router WAN port network cable to the inlet broadband network port to access the Internet.

A router is a device that connects various local area networks and wide area networks on the Internet, and it will automatically select and set routes according to the situation of the channel, and send signals in the order of the best path. Routers have been widely used in all walks of life, and a variety of products of different grades have become the main force to realize the internal connection of the backbone network, the interconnection between the backbone networks, and the interconnection between the backbone network and the Internet.

The steps to replace the router are as follows:

1. Remove your old router and connect the new router with the modem broadband network cable, if it is optical fiber broadband, you need to connect the network cable from the optical modem to the WAN port or WAN port of the router. If it is not fiber broadband, you need to connect the broadband network cable directly to the WAN port or WAN port on the router. Prepare another network cable to connect your computer to the LAN port or WAN port on the router.

2. On the nameplate at the bottom of the router, check the initial information such as the router's management address and default wifi name. Therefore, be sure to check and confirm the login address on the nameplate of your router. If you're going to set up your router with your phone, then connect your phone to your router's default WiFi network.

The rest of the steps are exactly the same as on the computer.

Meaning of router bridging

Bridging refers to the process of performing network packets according to the address of the link layer of the OSI network model. When the router is configured with the bridging option, it processes all data frames on all interfaces and investigates the location of each host in real time. If a frame is included on an interface, an entry is inserted into the bridge listing the MAC address of the host that sent the data and the interface MAC address that received the data frame, so that the routing table is continuously refined in the communication.

Transparent bridging makes the road posture high bypass transparent to the host, and its function is equivalent to a LAN switch. If two hosts in the same LAN communicate, the data frame will not be sent to other interfaces, because in the bridge table, the data frames are all from the same interface, if a frame is received, and the MAC address is not in its own Yanyan bridge table, the frame will be spread to all interfaces, and the bridge will also spread all broadcast packets, occupying the effective bandwidth of the network, causing network congestion.
