I had two computers at home, one for broadband, one for my dad and one for me, so I got a road bike

The network segmentation of the router, which is one of the most important functions of the router, can divide the entire network into different network segments according to actual needs.

2.The working process of the router is the third layer device in the OSI Layer 7 network model. When it receives any packet (including broadcast packets) in the network, it has to transfer the second layer of the packet (the data link layer).

(called "unpacking") to view the third layer of information. Then, the route of the packet is determined according to the routing table, and then the secure access table is checked. If it is passed, the second layer of information is encapsulated (called "packing, and finally the packet**"). If the network corresponding to the MAC address cannot be found in the routing table, the router will return a message to the site of the source address and drop the packet. That's where the router works.

A brief description of the program.

3.The limitations that the router imposes on the network The router is a connectionless device, and its working mechanism makes it a ** and forgotten network device. Just because the router has to have a "split" process for any packet, even if all packets from the same source address to the same destination address are sent to repeat the same process.

This makes it impossible for the router to have a high throughput, which is one of the reasons why the router becomes a bottleneck in the network.

Bandwidth allocation needs to be set up manually, which is cumbersome and not suitable for you.

Routing is a great way to get both of you online at the same time without interfering with each other, but if one of them uses a lot of bandwidth-intensive software, the other can use less bandwidth.

Depending on the demand, if one person places something, the other person will be very stuck

OK. Router to router, second router setup, there are two ways (provided that the first router is already set up):

The first method: dynamic IP mode (the first route is the primary route, and the second route is the slave route).

1. Plug in the router and do not connect the LAN port of the main router first, and reset the slave router (restore the factory);

2. Connect the computer to either LAN from the router

to enter the settings page;

3. Follow dynamic i

p mode setting;

4. Then set the SSID, encryption method and password;

5. Save and restart;

6. After setting, put the main route to LAN

The network cable that comes out of the port is connected to the WAN port from the router.

The second method: wireless AP mode.

1. Connect the computer to the LAN port of the router first, and change the IP address of the slave router. For example, most router addresses are, we just need to change from router IP address to that;

2. Turn off the DHCP function from the router in the settings;

3. Finally, connect the network cable from the main router to the LAN port of the slave router (any one is fine), note that it cannot be the WAN port.
