I have a router, that s all I have now with all the broadband what cable cats, landline, all in the

If there is only one computer with Internet access, just bring the phone line into the bedroom, and the cat is also in the bedroom.

If more than two computers are connected to the Internet, the Wan port of the router is connected to the back of the cat, and the Lan port of the router is connected to the computer.

Please be specific about the problem, if it is a cat and there is a line, it can be connected to 4 computers; If you use a cat and wireless router, you can connect a laptop with 4 computers and several wireless network cards; Since your cat has a routing function, it is recommended that you buy a switch (or HUB), 8 16 24 ports, which can be connected to the corresponding number of computers.

The router is connected to the cat, and then the cable from the router is connected to the bedroom, and you don't need to log in to the account if you set it up with the router.
