The internet is full of tutorials about using a Raspberry Pi as Router or how to set up a WiFi bridge but what I am looking for is something special I couldn't find any useful information about.
I have a Ethernet connection in my room but the WiFi from the router in the basement is not available here. However my tower PC is connected via the one single Ethernet connection anyway.
As I have a Raspberry Pi Zero W laying around I was wondering if it would be possible to plug the Pi Zero via USB to my PC and let it create a wireless network only for my room (something like an access point) that will route the data from my PC (which is obviously using the Ethernet connection) to the pi using its USB connection to the PC.
I would like to connect my smartphone to a wireless network in my room without buying new hardware.
I attached a primitive painting to explain what I am looking for.
