How do I fix dns address can’t be found error when searching internet?

[Android Central Question]

When I try to connect to most websites via my tablet, I get an error that dns address can’t be found. Also on some apps it says check internet connection. I have strong wifi signal and no problem connecting to google. It does not matter what search engine I use. I restarted tablet but that did not work. Thanks

To get to a website, the human readable name (www . google . com) needs to be converted to its IP Address (216 . 58 . 216 . 164). This is done by a DNS server. Which DNS server you use will depend on the internet connection you have (mobile data, home wifi, public wifi). The error you are getting is the "I cannot find that web site name" error from the server. This should result in the DNS server asking the upper level DNS servers to do the lookup and pass the info back down the chain. If a second attempt to reach the website fails, there is either a problem with the DNS server you are using or the name has a typo or the name really does not exist.

Unfortunately, there is no EASY way to pick a different DNS server from the one your internet provider is using. If you are sure the name should be found, you can follow the instructions at this website to pick a different DNS server, but note the warnings.

If you are going to do that, I'd recommend Google's DNS servers, 8.8.8.8 and 8.8.4.4. I use them, they're fast (they have servers all over the world to keep them fast to you wherever you are) and they're constantly monitored, so if anyone tries anything with one of them, it's fixed in moments - like by the time you try again.

But, as Joe said, heed the warnings - you'll have to know your router's address (that's the gateway address) and you'll have to use a static IP that your router will accept. If its DHCP server is set for 2-255, chop that down - make it, maybe, 2-20 (how many devices are connecting to your router, anyway?), then use 21 or 22 as your tablet's IP address ending. (The first 3 numbers will depend on the router - 10.<something>, 176.<something> or 19<something>.<something>. The first 3 numbers have to be the same as the router's IP address.) The subnet mask can be 255.255.255.0.
