|Now, our router is in our basement and my gaming computer is on the second floor|
First off, wireless sucks completely for gaming. More so if you have anybody else sharing your LAN and using up bandwidth which you appear to have.
Secondly, you're two floors away from the router so your signal strength won't be very high due to interference.
If it were me, I'd neatly pull a cable to your gaming PC and I'd get another wireless capable router and I'd connect it to the cable and then I'd plug my gaming PC into the router too.
This would extend your wireless network and improve coverage and signal strength throughout the house and would also provide you with the best possible gaming experience.
If you absolutely can't, or won't, pull a cable then you could try a wireless "range extender" and use that to do the same thing (with of course the exception of improving your gaming....as long as any component between you and the internet is wireless, your gaming won't be as good as if it were all wired).
For information on adding a second router just click on my name above in this response and read my “how-to” guide titled, “Add a second Router to your LAN” You'll want to use the single subnet scenario wherein you interconnect the two routers "LAN port to LAN port"
As an aside, the house I own has the basement ceiling finished with sheet rock making it pretty much impossible for me to neatly pull cables up to the main floor. My wife's home office is above mine (mine's in the basement) so I drilled a hole through the floor inside the closet. Luckily the closets also matched up so the cable is nearly invisible in both our offices. I'd have preferred a drop tile ceiling which would have allowed me to do a proper, professional, neat job of pulling to outlets but since I only had to pull one cable I did it through the closet. It's also worth noting that the ADSL modem and router are downstairs in a different part of the basement. As such my wife was getting poor reception on her wireless devices on the main floor so I bought a dual radio (2.4/5.0 GHz) wireless N router which I put in her office as per my guide and she has excellent reception for all wireless upstairs now.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
