Why is ping not getting through?

Question

linux

Greetings to all)
I decided to install archlinux. During installation, I encountered a problem with setting up the Internet (peap / mschapv2). With the help of this instruction https://bbs.archlinux.org/viewtopic.php?id=188783 I connected to the network. However, I ran into the following problem. When I ping an external resource nothing happens, I stop ctrl+z. When I turn to the internal resource of my network, everything responds.
I tried to make a request for the site with curl in the cut, I get the html of the provider's site, and so on when accessing any external site.
What could be the problem?

How are you connected to the Internet?
If directly, then the question is - is the network card configured in accordance with the parameters that the provider gave you?
I tried to make a request for the site with curl in the cut, I get the html of the provider's site, and so on when accessing any external site.
Isn't the provider's page with an error message hidden in this html?
