To block a website using your TP-Link router, you will need to access the router's web-based setup page and create a new website blocking rule. Here is a general outline of the steps you will need to follow:
1. Connect your computer to the TP-Link router either wirelessly or via an Ethernet cable.
2. Open a web browser and enter the router's IP address into the address bar. The default IP address for TP-Link routers is typically 192.168.1.1 or 192.168.0.1, but you can check the router's manual or label for the specific address.
3. Enter your router's username and password to log in. The default username and password are usually "admin" and "admin", respectively, but you can check the router's manual or label for the specific login information.
4. Navigate to the "Security" or "Access Control" section of the router's setup page. This will vary depending on your router model and firmware version, so you may need to refer to the manual or online documentation for guidance.
5. In the website blocking section, you should see an option to create a new rule. Select this option and enter the URL of the website you want to block. You can also specify the time periods during which the website should be blocked, if desired.
6. Save your changes and exit the router's setup page. The website should now be blocked on all devices connected to the router.
Note: Some TP-Link routers may not have the option to block websites directly. In this case, you may be able to achieve the same result by setting up content filtering or by using a third-party web-filtering application.
