Connecting a Router to Another Router as a Layer 2/3 Switch (?)

[news]

[wireless]

Hi. Excuse my likely misuse of terminology, it's been a good while since I've gotten any sort of education on Networking and the OSI Model.
I've recently acquired a laptop that does not have any WLAN card. Obviously, that means that it can only work through Ethernet. However, my router is on the ground-level floor of my home, and I am a literal basement dweller. As a result, using the internet with this laptop - which is something I want to do - is a no-go.
I do have an old router, however. I was wondering if it's possible to go into the Router's settings, and make a wireless connection to the current Router/Network that has access to the internet. Then, using this Old Router as an intermediary, I can connect the laptop to this Old Router and gain access to the internet through the Ethernet connection.
Is this possible? If so, how would I go about doing it? And please feel free to ask for any clarification.
Regards.
