How do I use a router as a switch, and how do I set up a router to use as a switch?

You connect the cable that came out of the cat to the WAN port of the router, and you see, it's the WAN port. The computer is connected to the LAN port with a network cable. Turn on IE from your computer, enter the IP address of the router in the address bar (generally, check the manual for details), and a web page will pop up, which will set the ADSL password.

In the future, the router will automatically dial the number for you, and your 2 computers only need to set an IP address or use the router's DHCP protocol service to automatically assign an IP to access the Internet.

You log in to the IP address of the land game to set the dial,It should be this,There is an address on the land game,The network cable out of the cat goes to the WAN port,The LAN port is connected to the computer。

Your question adds that you typed wan as lan, but don't know which lan in your question you want to fix, there are two "lans" in your problem

Home routers generally have one WAN and 4 LANs, and some have wireless.

You'll need to set up your router. If you have a router manual, you can set up PPPoE according to your router's manual.

Let me give you a brief introduction:

1, The local connection of the PC is set, the mask is, the gateway.

2. Connect to the router (play in IE.)

3. Set pppoe**, automatic dialing. Set DHCP.

4. Save and exit.

5. Modify the local connection of the PC to get it automatically.

At this time, you connect the cat's cable to the wan, and the PC to the lan, and you should be able to access the Internet.

1. Enter or, turn off DNS in the browser address bar, if there is a higher-level router, please set the router IP address to or, and other computers to set it to, anyway, pay attention to other IP address conflicts.

2.It can't be set because the IP address is already occupied by the higher-level router. However, some routers have a built-in switch mode, which you can set to switch mode directly after logging in, save it and exit it.

3. The router is used as a switch and wastes a LAN port, and other computers can only connect to the three free ports.

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. A router is the hub of the Internet"Traffic police"。

At present, routers have been widely used in all walks of life, and various products of different grades have become the main force to realize the internal connection of various backbone networks, the interconnection between backbone networks, and the interconnection between backbone networks and the Internet.

The main difference between routing and switching is that the switch takes place at the second layer of the OSI reference model (data link layer), while the routing takes place at the third layer, which is the network layer. This difference determines that routers and switches need to use different control information in the process of moving information, so the way they achieve their respective functions is different.

<>7.Then find the "LAN port setting", set it to manual mode, modify the management IP address to the different IP addresses of the same network segment of the main route, and then save it, then the router is set as a wireless switch (wireless AP).

Do you want to use your router as a switch? If you set it wrong, the consequences will be serious, so let's teach you how to set it up.

First of all, it is necessary to confirm whether there is already a router in the LAN, and usually the router is used as a switch when there are two routes at the same time.

Confirm the IP address range of the router on the current network to avoid conflicts when setting. There are many routes that have the same default IP.

Find a jumper to connect the router you want to set up as a switch to connect to the computer, and then set the computer's IP address to get it automatically.

After obtaining the IP address, we enter the IP of the router on the webpage to access, and enter the username and password to log in.

After logging in to the page, we first need to set the address of the router LAN port, click on the "LAN port setting" under the "Network Parameters" option in the upper left corner, and we will set the address in the upper right corner to remember not to conflict with the IP address of the router in use. The IP is set up in order to access this router later.

Because many people now use wireless routers, if you are a switch and do not need wireless functions, you can turn it off.

The most critical step is to click on the "DHCP Server" of the function option, and turn off the function after entering. If it is enabled, you will not be able to access the Internet from the main route, and you will not be able to access the Internet if you get the address to the address.

Use one network cable to connect the LAN port of the router and one to the computer. Why do I sometimes have access to the Internet?

Answer: The main problem is that your computer network settings conform to the management range of the router and there is no conflict with other computer IPs, such as the address pool of the router is (, it happens that your IP is in this range.

Sometimes you can't get on?

Answer: Your IP conflicts with the IP of other computers, and another point is that your IP does not meet the jurisdiction of the router, for example, your IP is an IP banned by the router and cannot access the Internet; Or your DNS server is not the address of the router; Or your gateway is incorrect, and you can access the network only if the gateway is correct and the IP address is not disabled.

Why use the switch directly, it is normal to be able to use.

Answer: The router is mainly responsible for the distributor of IP packets (the router works at the IP layer), and the switch (refers to the Layer 2 switch, which works at the physical layer) generally carries out the data packet through the MAC address. The main thing is that you can access the Internet, which is related to the network configuration of your computer.

If you want to know how they work, you can look up the principle of routers and switches.

First of all, go to the router, turn off the DHCP function of the router, and then change the connection mode of the router to a dynamic IP connection. Then change the IP address of the router to make sure that the IP address of the route is not the same as the IP address set by the other settings. Then just pick up a random lan port.

This way the router is fully in switch mode.

Absolutely. It's the same with our school. That is, the bus port (WAN) should not be plugged in. Plug both the bus and the breakout into the other ports only. That's it. Each machine has Internet access.

If you want to use the router as a switch, you only need to follow the steps below to set it up.

The following example is to connect a DI-624+A to a wired router and use the DI-624+A as a wireless switch, and all users obtain IP information from the wired router.

1.First, connect the network cable from the front-end router to one of the DI-624+A LAN ports, not the WAN port.

2.Go to the settings page of the DI-624+A router and turn off the DHCP server to prevent the connected computer from obtaining the wrong IP information.

Note: If you have another router on the front end of this router and it is also a D-Link brand, please change the LAN IP address of this router to another IP address of this network segment to avoid conflict with the LAN IP of the frontend router.

If the router does not set the second-level routing function (relative to the upper level) function, it will cause gateway conflicts if it is directly used as a switch, so it is recommended to query the IP address of the higher level and set the secondary level of the router you are directly connected to.

Go to the router factory reset 1 and wiring the 1-4 ports of the router arbitrarily, which is the usage of the switch.
