My bedroom, living room, and study are all reserved for network cable jacks, so don t you use a rout

You need to open broadband to access the Internet, generally a website is limited to one computer, and now Netcom Telecom has restrictions in this regard. You have left network cables in all three rooms, and you can only use one computer to access the Internet after opening, and you can't access the Internet at the same time, unless you use the router to set it up, and then other computers need to connect to the Internet through the router.

It is estimated that it is not possible, and the reserved network cable jack is connected to the main network cable.

There is no such thing as a free lunch, you need to have broadband to access, and your pre-installed network cable must be connected to broadband.

In this case, you have to apply to the community to open before you can get on, and the current cost is generally a little more expensive!
