How to fix the Internet on a remote computer via ssh?

Question

linux

There is a raspberry pi with a usb wifi dongle for remote access to raspberries. After connecting to the raspberry via ssh, the Internet does not work on it. It does not occur to me where to look, where to fix it.
System: Arch under arm for raspberries
Connection Manager: Connman
The situation is such that raspberries connect to a home access point and allow you to log in to yourself via ssh, but by itself it does not give access to the Internet, when pinging it gives Unknown host yandex.ru for example. When connecting raspberries via Ethernet to the same router, there are no such problems.
Tell me where to dig. Thanks in advance.
