Telecom users dial-up Internet access (telecom e9 package), one cat and one switch, how many computers can be connected at most?

Hehe, it doesn't depend on your network equipment, but on your broadband account. Generally, the number of terminals allowed for broadband accounts below 4M here is two, which means that you can connect two computers at the same time and dial-up the Internet using broadband connection, but the third one cannot be connected. There are four restrictions above 4M, but if the router is used to solve this problem, there is no such restriction if the router is set to dial automatically. I'm not sure where to limit the number of your computers, but there is a relatively simple test method, that is, you use a computer to connect to broadband, click broadband connection, and then keep broadband connection and click to disable local connection directly. At this time, the broadband connection will be disconnected, but the number of internet dials in the operator's database has not been cleared, and then the local connection will be enabled, then the local connection will be disabled, and then the local connection will be enabled. When you see the number of connections that can no longer be used, you will know what the limit is.
