Why can I connect to some websites but not others?

1. Check your Internet connection
   Ensure your device is connected to the network, and the router is connected to the modem and ISP.
   
2. Check the DNS settings
   Check the settings of DNS, if it is not set properly it won't connect to websites.
   
3. Check Firewall/ Antivirus settings
   Make sure the Firewall settings allows the browser to access the network and the Antivirus is not blocking the website.
4. Disable Internet Proxy
   Disable the internet proxy option in the browser settings, so that it bypasses the proxy server and directly connects to the website.
