My Xiaomi has WIFi, so I can't watch videos online, but I can cache, buckle, browse the web and play games offline, but I can't surf the Internet.

First of all, you need to install the driver of Xiaomi's portable WiFi. If you still can't create a WiFi network after installing the driver, it may be related to the missing/disabled components of your Windows system. If some simplified Windows systems will delete some system network components, or your security software/firewall prohibits the network from enjoying functions, I suggest you download and install Windows patches and modify the local security software/firewall configuration to solve this problem.

After successfully connecting Xiaomi's portable WIFI network, the mobile phone can't open the webpage. I suggest you confirm whether the computer can surf the Internet normally first. If the computer can open the webpage but the mobile phone can't open it after connecting to WiFi, it may be related to the client login method used by your network operator, such as Tianyi client, Ruijie client and other products, which may restrict network access. If you encounter such a situation, I suggest you go to Xiaomi community-Xiaomi portable WiFi version to find a solution.
