The difference is: they are all dial-up, it’s just about who dials up. Both modes are controlled by the operator by default. Automatically obtaining an IP address can make it more convenient for users, but it cannot obtain a public IP, which means that it cannot build a server and use P2P services.
The operating environment of this tutorial: Windows 7 system, Dell G3 computer.
1. Broadband dial-up Internet access
Broadband dial-up Internet access, some routers are called: ADSL dial-up, PPPoE dial-up, etc. They all have the same meaning, that is, you need to enter your Internet access account and password to access the Internet.
Generally speaking, when handling and activating broadband services, the operator provides you with: broadband account number and broadband password, and you need to use the "Broadband Connection" program to connect. After the connection is successful, Only when the computer can access the Internet normally, select the "Broadband Dial-up Internet Access" method when setting up the router.
2. Automatically obtain an IP address to access the Internet
Automatically obtain an IP address to access the Internet. In some routers, it is also called: dynamic IP Internet access, DHCP Internet access, automatic acquisition, etc.
Plug the network cable from the cat into your home, or the network cable that the operator pulls to your home, and plug it into the computer. You can access the Internet directly without any other operations. This is the case of "automatically obtaining an IP address." Internet access.
When setting the router's Internet access method, you should select the "automatically obtain IP address" Internet access method.
Now the optical modem should have two modes: "bridge" and "routing". The "bridge" mode requires an external router to dial, and the "routing" mode requires the optical modem to help you dial the number. The optical modem will also become Once it becomes a router, it can automatically obtain an IP address and use it.
These two modes are actually dial-up Internet access, it just depends on who dials up. These two modes are controlled by the operator by default. Our Telecom can modify it through the online business hall. I don’t know if China Unicom can do it. To get rid of the operator's control, you need to turn off the "remote management" of the optical modem. The specific method can be Baidu's "optical modem to bridge" and "optical modem close remote management". Different models have different methods, but they can all be solved.
Automatically obtaining an IP address can make it more convenient for users, but it cannot obtain a public IP, which means that it cannot build a server and use P2P services. The operator may be doing this to save uplink bandwidth and not allow you to set up a server.
Generally speaking, the vast majority of broadband services handled by home users are: broadband dial-up Internet access. The second is: automatically obtain an IP address to access the Internet.
