This article will teach you how to fix your computer’s Internet connection problems caused by errors in the Domain Name System (DNS). DNS is a server that translates website addresses so your browser can connect to them. If the addresses become outdated or the server has problems, you will find a DNS error and you will not be able to connect to one or more specific sites even if you have Internet access. It is possible to fix DNS issues by resolving your current connection, clearing the DNS cache, disabling additional connections, changing your computer’s default DNS server, and even restarting your router.

The steps

Part 1 of 5:
Troubleshooting

1. 

   Connect with another device. If you can connect a phone, tablet or a computer to the network and access the website you are having trouble with on your primary device, the issue is most likely with the device and not the router.

   • If you can’t connect to the second device, that doesn’t necessarily mean the router is the problem.
   • If you’re having trouble with a specific website, try access it using your mobile data. If you still can’t access this website, it means the problem is last.

2. 

   Use a different browser. This is one of the quickest ways to test your DNS connections. Download another free browser, such as Firefox or Chrome, and try to connect to the Internet. If the problem persists, you can rule out problems with the browser as the cause of the malfunctioning DNS server.

   • If the problem is not solved, uninstalling and reinstalling the old browser probably is.

3. 
   

   Unplug the modem and router. This will clear the router cache, which may resolve DNS server errors. To do this, follow the steps below:

   • Disconnect the power cable from the modem and the router.
   • Leave them disconnected for at least 30 seconds.
   • Reconnect the modem and wait for it to reconnect.
   • Reconnect the router to the modem and wait for it to reconnect.
4. < p>
   

   < br/> Connect your computer to the router via Ethernet. If you are already using an Ethernet connection, skip this step.

   • If you can connect to a website while using an Ethernet connection, the problem may be with the router. Most likely you need to restart it.
   • If you cannot connect to a website when connected via Ethernet, the problem is most likely related to the DNS configuration.
