That is pretty wierd about getting better speeds with something else running.
The RWIN (recieve window) is set automatically for the best download in Vista so that shouldn't be a problem.
First, the speed tests that are out there are very unreliable.
Go to a site like Microsoft, HP or Adobe that has a big pipe and download a file in the 15 to 20 MG or more and cancel it at about 50 or 60% and see how it comes out.
Are you behind a router? If so take that out of the mix and hook your computer straight to the modem.
Are you running ethernet or USB to the modem? I know stange things happen when using USB.
I Have Comcast Cable for my Internet and using ethernet and after I installed Vista my speeds actually went up and have stayed up for the past 6 months. The only difference is I have Vista home premium 32 bit.
Hi, I have Vista Ultm. 64bit and my ISP limit is 8600/1120 kbps. When I run speed tests or download from any server, it never exceeds 4000 kb/s. But if I run something in background let's say windows solitaire the download speed immediately goes up to average 7000-7500 and stays like that until I shut solitaire down. Anyone have any ideas on that?
