Checking network connectivity
│
│ - Command: ping -c 1 -W 5 1.1.1.1
│ - Exit code: 1
│ - DietPi version: v6.27.2 (MichaIng/master) | HW_MODEL:3 | HW_ARCH:2 | DISTRO:5
│ - Image creator: DietPi Core Team
│ - Pre-image: Raspbian Lite
│
│ Log file content:
│ PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data.

How I fix this:
1. Reboot, becouse nothing work.
2. After reboot, on all screen (for passowrd ..) - chose <Cancal> (need to open terminal).
3. sudo nano /DietPi/dietpi.txt
4.At the bottom, replace 1.1.1.1 and one.one.one.one with 8.8.8.8 (google dns)
