Problem with Hacks

Everytime I use the hack called "Injector" or some type of hack, it works fine but then in the middle of a game, or if the game is up too long, the game says that I'm going to lose connection, and my internet is fine. I'm running wireless and I don't know if that is the problem, or something is wrong. It does this every time I want to play a game, I end up losing connection to the game or something, I don't know.
Can anyone help me?

The gameguard is probably detection your hack.
