How to set up a device so that it cannot access the Internet

How to set up no internet access permission

In modern society, the Internet has become an indispensable part of people's lives. However, there may be times when we need to limit access to the Internet, such as setting limits on children being able to access the Internet at home, or limiting employee access in certain workplaces. So, how do we set this up without internet access? Below you will find some solutions.

1. Router Settings

Most homes or offices have a router that provides wireless network connectivity. If you want to restrict access to the internet, you can set this up through your router. The specific method is as follows:

First, open your browser, enter the IP address of the router in the address bar, and enter the administrator username and password to log in to the router's management interface. Each router's management interface may be different, but you can usually find the information on the router.

Secondly, find options such as "Wireless Settings" or "Parental Control" in the management interface. Here you can set access control lists (ACLs). Access control lists can be used to restrict Internet access to specific devices during a specific period of time.

You can then add the MAC addresses of the devices you want to restrict and set a time period and date for access. During the period of unauthorized access, the restricted device will not be able to connect to the Internet.

Finally, save the settings and apply them to your router. In this way, you have successfully set up no internet access.

2. Operating System Settings

In addition to setting access permissions through the router, you can also achieve this through the settings of the operating system.

For a home or office computer, you can restrict access to the Internet in your operating system settings.

In the Windows operating system, you can set it up by following the steps:

First, open the "Control Panel" and find the "Network and Sharing Center".

Secondly, click "Change Adapter Settings", find the network adapter you are using, and right-click to select "Properties".

Then, in the "Properties" window, find "Internet Protocol Version 4 (TCP/IPv4)" and click "Properties".

Next, in the "General" tab of the "Properties" window, select "Use the following DNS server address" and set an invalid DNS server address, such as "0.0.0.0".

Finally, click "OK" and save the settings, so you have successfully restricted the computer's Internet access.

For mobile devices, such as smartphones or tablets, you can set restrictions in the device's settings.

On Android devices, you can follow these steps to set it up:

First, open "Settings" and find "Wi-Fi."

Secondly, select the Wi-Fi network you are currently connected to, and press and hold to select "Modify Network".

Then, in "Advanced Options", find "IP Settings" and select "Static".

Next, enter an invalid DNS server address, such as "0.0.0.0", in the "DNS 1" and "DNS 2" fields.

Finally, save the settings and exit to successfully restrict the mobile device’s Internet access.

To summarize, setup without internet access can be done through the router or operating system. Whether in your home, office, or other location, you can choose the appropriate setup method based on your needs and situation. I hope the above methods can help you to restrict Internet access.
