I have a Comcast modem in my basement that i hook up to with a wireless adapter from my computer which is on the 2nd floor. I am able to connect but the connection is horrible when i play BF3. Would buying a good router around $50-$70 and hooking it up to the router w/ ethernet improve the connection? The modem is in the corner of my basement and i cannot move it because it is with my cable and telephone, but if i got a long ethernet and a good router to place the router in the center of the house in the basement, would that help the connection at all? Any other suggestions would help.
