The interface has an IP address. If you run:

if you run:

echo "nameserver" | sudo tee /etc/resolvconf/resolv.conf.d/tail > /dev/null

And reboot, do you get web access ok?

To do that without HDMI connected or? And if I get no web access how to let u know, or repair it?

Either way, it doesn't matter

And if I get no web access how to let u know, or repair it?

Can you help with this problem?
