It is possible only between apple routers.. so only if you downstairs router is another apple.. otherwise NO.. it will not work.
You can use EOP adapters.. or buy a cheap second hand apple router or even an Express.. but the wireless is second best or third best option IMHO. Ethernet is tops.. EOP is good if it works.. wireless is runner up.. ie last.

Why not try a pair of these over domestic power loop.
Not cheap though Best buy link
The Apple solution might well need Two devices to extend range.
You would retain your ISP router/modem however would go into settings and TURN OFF wireless on that device - you can do this in the Java Web based control panels on most routers.
Now you sling the Ethernet cable between that router and a purchased Time Capsule device locally and set this up to create a new local Wifi network (Replacing that of the ISP supplied router) . Being a dual band device and being able to broadcast both over 2.4 Ghz and 5 Ghz frequency base bands simultaneously you could well see improved performance and range straight away.
However if not then you are going to need a further device an Airport Express set up in bridged mode somewhere between the Time Capsule and your upstairs rooms. Your may have to try various power points and locations to get coverage required.
Further Airport Express devices can be added in bridged mode as required to cover blind spots, however remember each additional device degrades the overall network performance somewhat.
Again this will get quite costly.

The downstairs router is not an apple product... darn. Looks like we need to find a way to get an ethernet cord upstairs haha. Thanks!
