first step
First, prepare a computer, a mobile phone, and a mobile phone to install a handheld university (different terms in different regions, use the software that you can log on to your broadband account). The function of the mobile phone is to log in to the account, and the function of the computer is to manage the router. No computer? Then use another mobile phone instead of a computer to manage the router. Turn on your mobile phone and find the MAC address of your mobile phone. This article takes iphone as an example. How to find other mobile phones on the Internet. Settings>General>About this machine>Wireless LAN address, remember your MAC address after you find it, you will need it later.
Second step
The network cable is connected to the WAN port of the router. Then the computer connects to the router WiFi . Generally speaking, wireless wifi can be connected. If your desktop computer or cannot access the management page, you can directly connect your computer to the router LAN port with another network cable. Enter your router management address in the browser. It is written on the router, or in the manual, usually 192.168.1.1 or 192.168.0.1. This article takes 360 router as an example.
Click Internet settings, different routers have different opinions, but you can probably see the picture below after you go in, and it is basically correct. 
There is a MAC address in the above picture. The first step is to replace the original MAC with the MAC you found. After the change, remember to save it, and then we choose static ip to go online.
third step
At this time, look for it directly, and go to router settings>modify router settings. The sentence depends on your router. Find the DHCP server, as shown in the figure: 
Then connect the network cable to the router lan port, that is, pull the wan port to the lan port, and then turn off the DHCP server (above), remember to save it.
the fourth step
Connect the mobile phone to the router WiFi , open the Pocket University, and log in to the broadband account. Then go to see your WiFi details, this article still uses iPhone as an example. 
After turning off dhcp, if the IP you get starts with 192.168, there is no need to take the next step. If you made a mistake in the previous step, go back and check immediately; if the IP you get starts with 10.195 , it means success. I circled the part and filled it in the second step.

All the information to be filled in the picture above comes from your mobile phone. After saving, turn on the DHCP server, the one that asked you to turn off just now, then connect the network cable to the wan port, the computer will go online normally at this time, and you're done. Can't get on the phone? Just reconnect to WiFi.
Every 24 hours, Tianyi.com will redistribute ips for you, so I will perform the above steps again, so troublesome? Rest assured that generally other information will not change, but this IP address.
