Hi
@slynightsky - welcome to Computer Forums!
Generally speaking, even on a 200meg connection, wifi performance can be quite variable especially if you have a larger home.
The first thing I'd say is, if you're able to, would be to try and move the router to a more central location, though this may be difficult depending on where your connection comes into your house.
Otherwise there are all sorts of products out there, what works for you might unfortunately involve a bit of trial and error.
The first thing I would try in your position would be a wifi extender. It essentially copies the signal so it will only perform as well as the signal it receives and it may slow things down a bit, in exchange for a more stable connection...
