copy the text to a text file - transfer using usb
To get ouput into a file without an editor pipe the result to file
e.g. inxi
inxi -Fxxxx > ~/inxi.txt
or from systemd status
systemctl status NetworkManager > ~/status.txt
or appending several commands to the same file using a append pipe
echo inxi -Fxxx >> status.txt
inxi -Fxxxx >> ~/status.txt
echo systemctl status NetworkManager >> ~/status.txt
systemctl status NetworkManager >> ~/status.txt
echo journalctl -xe --no-pager >> ~/status.txt
journalctl -xe --no-pager >> ~/status.txt
Or if you have an android phone you can tether your phone internet on the dysfunctional system
I use protonvpn - I have never experienced this issue - but hey - there is something - if you are not using systemd-resolved - the resolv.conf is not always reset correctly - especially if rebooted while connected
