Answer 1

You will see the same performanc with a 3 meter, 15 meter, or 100 meter ethernet wired connection...  The speed won't decrease with those lengths...  

Answer 2

Stick to using a wireless connection to avoid the hassle of running all that cable downstairs. A wireless connection is good as long as it's within 50 feet of your router generally. Connecting your computer via ethernet cable won't make any improvements, since the internet speed isn't influenced by whether or not you use your cable to connect or by a wireless connection. Only advantage you would gain by using an ethernet cable is if you plan on transferring files from one computer to the other in your home, since the transfer speeds would be much higher than if one of the computers had a wireless connection.
