tweaking rwin

My wireless network is slower in Vista than XP. Now this is not a
disaster because I'm getting 11MBPS. However, if I connect to router
via an Ethernet cable I get 29mbps. I've been advised to set the rwin
higher, to about 256,000. As far as I can tell, Vista is setting the
rwin dynamically. Is there a way to change the rwin in Vista? In XP
there were a bunch of tools, but I think Vista does this quite
differently. Thanks

TCPOptimizer from speedguide.net. It now works on Vista.

Prior to running TCPOptimizer, I could get about 4MB/s throughput on
my LAN (gigabit) using the TTCP utility. This throughput was between
an XP machine and a Vista machine, all with GB cards and a GB switch.
Yet from XP to to XP I was getting 36MB/s.

I then ran TCPOptimizer, rebooted, and now get a consistent 33MB/s
from Vista to XP and vice-versa.
