I use a cat and a router to connect two machines, how to set up the router and the machine

First. Whether you set the IP or not. When there is not DHCP server setup. You have to manually set the IP address yourself. Second. Whether the network cable is connected. Ability to access another computer.

Third. Are you sure that the route setup is complete? (I won't teach you how to set up routing, you can find the setup wizard above.) The corresponding fill in is complete).

You see if your DNS is matched, 90% of you don't configure DNS, just point your DNS to the IP of the DNS server in the city, if you guess correctly, you can now get on QQ, but you can't get on the Internet.

Since you use the cat to surf the Internet, you have to dial up, and you still have to dial up after connecting the router!

Router 2 sets up dynamic IP to surf the Internet

1. Prepare 2 network cables, one end of which is connected to any LAN (1 2 3 4) interface on router 1, and the other end is connected to the WAN interface of router 2; The other network cable connects one end to any LAN (1 2 3 4) on router 2, and the other end connects to the computer.

Connect a cat to 2 routers to surf the Internet, connection method 1

2. In the setting interface of router 2, click "Network Parameters" - WAN port setting "- WAN port connection type" and select: dynamic IP (called "auto acquisition" and "DHCP" on some routers) - click "Save".

3. In the setting interface of Router 2, click "Network Parameters" - LAN Port Settings" - "IP Address" on the right side is modified to: > click "Save", and then the router will be prompted to restart.

Router 2 Setup Dynamic IP Internet Settings Summary:

1) The LAN port of router 1 is connected to the WAN port of router 2.

2) Router 2 sets dynamic IP to surf the Internet.

Step 1: Line connection 1 First, plug one end of a network cable into the 1 port or 3 port of the LAN port of the mobile all-in-one machine (because port 2 is the dedicated port of IPTV), and the other end of the network cable is connected to the WAN port of the wireless router 2 with another network cable, one end is connected to the LAN port of the new wireless router, and the other end is connected to the network port of the computer: 3 This method is only for the new router, or the router that has been factory restored.

If you are using a router, you need to factory reset the router first, press and hold the black button on the back of the router and wait for a few seconds, then release it to restore the factory settings. Step 2: Route Settings 1: Open the browser of the computer, enter "Because the address of the mobile modem is" in the address bar, and then enter the administrator login password (this password is used to log in to the router management interface, not the wifi connection password) in the box pointed by the home, and click OK.

2. Select "Automatically obtain IP address" in the Internet mode (because the mobile optical modem all-in-one machine has its own routing function, so the new wireless router does not need to perform broadband dialing) 3. Wireless settings, give your WiFi a name, and then set a WiFi password by yourself, click OK. Then tap Skip twice until the router management interface appears. At this time, the new router has been set up, and you can use your mobile phone to log in to the new wifi to surf the Internet.

Hardware: The LAN port of the router and the modem.

Software: Set dial-up connection on the cat, DHCP

Dial-up connection ensures that the cat can connect to the Internet service provided by the operator.

Enable DHCP to ensure that the modem can assign IP addresses to devices connected to the LAN portAdditional note: The router also has two working modes.

Router mode: The device between multiple routers is not in the same LAN as the modem.

The setting is simple, and the WAN port is connected to the cat LAN port.

Switch mode: The device is on the same LAN as the modem, and the devices between multiple routers are on the same LAN.

Slightly complicated, do not connect to the cat LAN port first, connect the mobile phone to the router wifi, log in to the background, change the router Internet access mode to automatic acquisition, change the LAN address to the same network segment as the cat Any unoccupied IP, and turn off the router DHCP function; Connect the LAN port of the router to the LAN port of the cat.

1. One cat can connect to two routers.

A cat can achieve 2 or more routers to access the Internet. But it's not like connecting both routers to the cat. Instead, connect the first router to the cat and set it up to surf the Internet.

Then connect the second router to the first router and set up the second router to finally realize that both router can access the Internet.

2. If only one broadband is enabled, you need to enable the routing function of the fiber modem, and you can connect the two routers through cascade. If you use a modem to activate two optical fibers, you can connect two routers separately, and the two routers can dial up Internet access separately, but the cost is higher.

3. There are two ways to connect between two routers:

1) Connect wirelessly.

Connecting two routers wirelessly is called a wireless bridging (WDS bridging). If you want to use the wireless method, connect the two routers to surf the Internet, the premise is that the first router and the second router both support wireless WiFi, and one of them cannot use this method if it does not have the wireless WiFi function.

2) Wired connection.

Compared with the wireless connection mode, the distance between the two routers can be farther and more flexible, and the network is more stable. However, wiring is required, which is more troublesome.

When using wired connection, only the second router has the wireless wifi function, and after setting, the wireless wifi on the second router can be used normally, even if the first router does not have the wireless function.
