If you have a router, find the DNS server settings page of your router or check with the routers manufacturer website to know how to navigate to the DNS server settings page. If you don't have a router and your computer connects directly to your modem, then you should know how to find your DNS server settings page on your computer, it varies wether you are using a Mac,Windows or linux based operating system. If you already know how to do it then proceed to the next step.
The most common reasons why you can't access certain websites or have internet connection problems is because of your ISP (Internet service provider), not your computer, and especially not your modem or router. Mostly it is because your ISP is not maintaining their DNS (Domain Name System), don't worry about the technical stuffs for now.
Once you have found your DNS server settings on your router or computer, replace it with this.
