Ah, I can understand that! We actually had some pretty terrible internet when we first moved in, but for us it was because the base modem and router weren't all that great. We have better luck since we bought our own.
Like, when we first moved in we started playing LotRO and in the middle of group content we'd freeze up and one of us had to quickly log out so the other would have enough internet to live. His class was more important so I got to be the link dead person. There was also the "We're in the middle of an orc camp. Quick! Force close the game so we're not dead when we get back!" Fun times~
