Happy New Year all, First of all let me introduce myself and somebody who is moderately literate when it comes to computers. My computer is homebuilt and I can normally find a solution for a problem and fix it myself. However this one completely baffles me. The problem is that ANY download (with the exception of certain P2P downloads such as Torrents and certain online games) starts downloading at normal speeds, and then rapidly plummets to 0kb/s. And any streaming video ie. Youtube, randomly stops at a certain point and will go no further even after refreshing. A few pointers; I am running Vista Ultimate 64bit, and recently partitioned my HD to dual boot with Win7 Ultimate 64bit however both OS' experience the same problems. I have tried to download the files on Chrome, IE and Firefox all with the same results. I also have a laptop running XP 32bit which does not experience his problem. I used to run Kaspersky with the same issues, but my sub ran out so now using standard windows firewalls, disabling the firewall makes no difference. As I have no idea what the problem may be, please let me add that I am using an Nforce Networkingcontroller, which i do not believe is the issue however. And my router is a Netgear WPN824v3 My ISP is Tiscali (whom I do not recommend whatsoever!) Note: http://www.techsupportforum.com/forums/f217/solved-internet-stops-downloading-after-a-few-seconds-515031.html This forum sounds particularly similar, pointing to a potential issue with Windows Scaling or something? I have tried "netsh interface tcp set global autotuninglevel=disabled" yet to no avail. I am convinced now that this must be to do with my router perhaps not supporting TCP Windows Scaling.
