Windows 10: ethernet does not have valid IP address

I have a W10 PC away from my main computer linked to my main wireless network by an airport express. All worked well but when I re-started after an absence of a month I could not get connected to the internet from my remote computer and had the message 'Ethernet doesn't have a valid IP configuration'. My main PC connected without any issue.

So a series of attempts to get a connection led to re-booting the airport express, the PC and main modem but all attempts failed to make a connection and any diagnosis repeated the above message. As a last resort, I plugged in a long Ethernet cable directly and suddenly all was well.

So I am now trying to understand the nature of the original problem - so that I can remove the long cable. Since the direct cable works, it looks as though the settings are OK for the Ethernet. So does this mean that it is the airport express wireless link that is the issue? The unit appears to be working OK but am I missing something else?

Thanks for any help.
