I installed telecom broadband in Haikou and accessed the Internet through Tianyi Broadband. How can I use two computers to surf the Internet after I buy a router?

Read the router manual! Check whether the router address is192.168.0. 192. 168. 1. In the address bar of the webpage, it belongs to the corresponding192.168.0.1or 192. 168. 1. When you enter the router, there is usually an introduction to quickly set up the router. Just look at it yourself and save the password of the online account in the router.
