Is it possible to connect a router with a switch split cable?

Hello! Yes:

1. Find a network cable to connect the LAN port of the router you want to add to the computer, enter the IP address and account name and password of the router through the IE browser, and log in to the settings interface of the router: here you need to find: "Network Parameters" - LAN Port Settings - set the IP and subnet mask of the LAN port, the IP should be set to a different network segment from the previous level, if the LAN port of the upper level switch is set to:

2. After setting the parameters of the router, you can use the network cable to connect the switch to the LAN port of the router, and the computer that wants to access the Internet through the router will be connected to the remaining LAN port of the router, and the WAN port of the router cannot be used!

If the connection is set up, you can't surf the Internet normally, check whether the "DHCP Server" - DHCP Service of a router is turned on, if not, turn it on, set the IP and DNS of the computer to automatically obtain, if it still doesn't work, you turn off the DHCP service in the router, I have taken two before no problem! Try it too!

Then you use the router as a switch, and it's simple:

It's best to turn off the DHCP of the router without using the WAN port, otherwise, it may conflict with your local area network.

A router that does not use a WAN port is actually a switch;

Yes:As long as you have the network cable from the switch, you can connect to the Internet. In fact, the router is just a switch with a chip that can dial up the Internet.

Yes, and it can be managed separately.

However, the disadvantage is that it is easy to conflict with the upper-layer router and affect other machines to access the Internet, so it is best to change the gateway of your router and turn off DHCP

You can connect to the switch directly and connect the router to set it up as a switch (the same goes for wireless).

Yes, that's how our dorm is connected.

Yes, if you have other computers, you can also connect to this switch and surf the Internet together, and you don't need any setup.

Yes, buy a switch, plug this network cable in, and then connect a few cables out, and you can get on it (of course, the premise is that people's network speed is enough, otherwise save a little, don't expect too many machines to go online, otherwise the speed of "other people's homes" will also be greatly affected).

If he doesn't restrict you, you have to use the switch to split the n-root share;

If there is a restriction (only one is allowed), it will be shared with a router;

Definitely yes. It's equivalent to you sharing the network at the top of his side. According to what you said, the upper gateway is DHCP turned on, and then the IP can be obtained.

You just plug in the internet cable and set your computer's local connection to get it automatically. If it doesn't work, just see how your friends set it up. If you set a static IP address and you change it to a static IP address from the same network segment, you can fill in the same mask gateway DNS.
