The extra fancy go-fast options in the TCP protocol are negotiated between sender and receiver. In any case, even if the router could do anything, by definition a bridged device, which is what your talking about here - is a layer 2 only device and cannot modify the packets in any way. If you would be willing to tell us exactly what your Internet connection is, what hardware/software devices it consists of, and what speeds it is supposed to be and what speeds your seeing, we could give you some advice that might help you out.
