Short version, I'll provide additional details if you need them.

I'd first look at current IP address either in Gnome's network settings of with the use of ip a command in cli. If you know what your IP address should be and it's currently different -- then we need to resolve how your computer should receive an address (most likely from your router?) and why it doesn't do it. Please tell, if that's the case.

If you don't know, if IP address is correct one or not, then the most basic way to test connectivity is with the use of ping cli command. Basically, you need to test two things:

  1. Can you computer connect to some IP address in the Internet? (1.1.1.1 or 8.8.8.8 are good and easy ones to test)

  2. Can you computer resolve website addresses such as fedoraproject.org or google.com?

If both are yes then you have a good connection. If one of the answers is no -- you need to resolve the problem with it. And to resolve anything you first need to understand, which of the two is the problem.


First ping test would be

ping -c 10 1.1.1.1

If you see replies from 1.1.1.1 and 0% packet lost in the statistics report -- then (most likely) you're connected to the Internet (and so your IP address should be the correct one). Then run the second ping test.

If the command seems to hang (that's because no replies are coming in), says Destination Host Unreachable, and says 100% packet loss in the statistics -- then you have no connection to the Internet.


Second ping test would be

ping -c 10 fedoraproject.org

Again, if you see replies, then you dns config is the right one, you connection is ok. If the browser still can't connect -- we need to look at browser's configuration.

If there's an error like this: ping: fedoraproject.org: Name or service not known, then your dns configuration is wrong. I'll try to provide some tips, if that's the case.


Please tell what's the results of the test are, or if you need additional help to perform them.

i checked /etc/sysconfig/network-scripts/ in network-scripts, It was ifcfg-enp3s0 that would be ifcfg-enp5s0... i changed ifcfg-enp3s0 into ifcfg-enp5s0. Now i can use the internet..without worrying... thanx, anyway

If you use Fedora with a GUI, in general you don't have to change/edit your network scripts, NetworkManager does that for you. Unless you've disabled it or something, of course.

Checked my network-scripts folder, and it too contains a script with a wrong device name. Still my connection works because configuration in NetworkManager was updated correctly to refer to new device name.

In any case glad you were able to resolve your problem.
