My Mini connected via AP to the router gets full connection speed. My wife's Mini connected to my Mini via AP and Internet Sharing gets full speed. Only when her Mini is connected via AP to the router is when her connection speed is half to 2/3 what it should be (dl speed is half to 2/3; ul speed is full).
