On Your Network If you have a Wi-Fi network in your home, it’s easy to block the website you want via a Wi-Fi router. Most routers don’t have user-friendly interfaces, so this can be a bit annoying. One more thing, the steps to do this vary with each router, but the basic process will remain the same. So if you exercise some restraint, then in reality this method is very easy. One more thing to note that if you tamper with any wrong settings then it is possible that your connection may be closed. Therefore, if you get stuck somewhere, contact your Internet service provider immediately.

1. We followed this process on Beetel 450TC1 router provided by MTNL in Delhi. Apart from this, also on the Binatone router provided by Airtel. The same process had to be followed on both the routers. To get started you need to go to the router’s settings. Open any browser and then type in the address bar. Then press on enter. This address is different on some routers, so if it doesn’t work, check the documentation provided by the Internet service provider to see if it is mentioned.

2. Now you need to enter username and password. It must have been set up at the time of your connection installation. By default username: admin and password: password. If it is not there, contact your Internet Service Provider and get the correct username and password.

3. We have already mentioned that interfaces can vary. In our MTNL router we found that we can block website through Access Management > Filter option.

4. There is a drop-down menu here, which is known as Filter type selection. We chose URL Filter and then entered the names of the websites we want to block in the URL field. Above this field is an option named Active. Here we see two buttons, Yes and No. We chose Yes and clicked on Save. With this we wish that all the websites are blocked.

5. You can create 16 list of blocked websites, in which each list will have 16 websites. In this way you can block a total of 256 websites. Will say once again that this process may be different in every router.

This guide will help you block websites on almost all devices. If you know any other way to block website then do let us know through comments section.
