I have no IP address after resetting my network

It looks like you are normally using Wifi. (Because wired ethernet is disconnected.)

The Wifi adapter sees signal from a known network (green bars), but you are NOT actually connected to it (it says "Not Connected").

So the Wifi adapter probably has the setting "Automatically Connect" switched off (this sometimes magically happens after a Windows update) and you have to re-connect it.

Only AFTER that has been done the DHCP server can give you an ip-address.
