What should I do? I used my phone to turn on the hot spot and told the computer that the internet was limited. The IP of the ipv4 was automatically obtained. I used to be able to use it, but now I can't.

This problem involved the network settings and the allocation of the IP address. First, he checked his phone's settings. Make sure that you have selected "Allow Internet Connection Through Hotspots" and that you have enabled the data connection. If you're using an Android phone, you'll also need to make sure that the "mobile network" or "cellular data" option is turned on. If everything is set up correctly, the reason why you still can't access the Internet is probably because the IP address has been assigned to another device or network connection. In this case, you can try to change the IP address of the mobile phone's hot spot. The specific operation was as follows: 1. Open the phone's " settings " application. 2 click on the "Network and Connection" option. 3 Choose "Mobile Network" or "Cell Data". 4. Choose the 'Advanced' option. 5 Find the "Hotspot settings" option and choose "Change Hotspot settings". 6. Choose "Wi-Fi" as the "Network Connection Type" and click the "Change Type" button. 7. Choose the option 'assign IP address automatically' and enter a new IP address. 8. Re-connect the phone to the hot spot to ensure that the Internet can be successfully accessed. If changing the IP address still does not solve the problem, you may need to check the computer's network settings. You can try to restart the computer and check if the IPv4 address has been automatically assigned. If the IP address has been automatically assigned but the computer is still unable to connect to the Internet, you may need to change the settings of the routeror re-allocate the IP address. If none of the above methods solve the problem, you may need to contact your network service or technical support personnel for help.
