poor network performance w/Vista Ultimate - software related?

[F@TMAN]

I've been experiencing poor network-related performance ever since making the move to Vista Ultimate (albeit with a new system) - anything from internet to network file transfers (if security settings will allow!). I also have a laptop that can perform brilliantly via. WLAN, however experiences similar performance issue when LANning (Vista Home Premium), so I've focussed on the following areas to solve:

*hardware - router, LAN cable/card
*software - vista

I've tried a different router port (Dynalink RTA1025W), different LAN cable and card (both cards using Realtek chipsets), however have not had significant luck (will admit slightly better performance). Software-wise, I'm not using firewall, and I've disabled TCP auto-tuning and Remote Differential Compression (I've also booted into safe mode w/ networking and did not notice any improvement, hence not concerned with 3rd party apps). I just can't figure out why I'm downloading close to 8Mb via WLAN, whereas LAN can barely do 1Mb...I do appreciate any further trouble-shooting suggestions, cheers

Hey,

I'm by no means an expert on Vista, but I have read about poor performance in vista before, some people get it some don't. Is it patched up?

You try looking at this article: http://technet.microsoft.com/en-us/magazine/cc162494.aspx or http://technet.microsoft.com/en-us/magazine/cc162480.aspx or http://technet.microsoft.com/en-us/magazine/cc162458.aspx.

Might give some insight into the way the kernel operates. Let us know if you have any joy. :)

I forget exactly what it's called but there's a network mapping service in Vista that kills network performance. Basically it attempts to interrogate all machines it's networked to to the nth degree to discover any attached devices and the full extent of any shared folders, more or less in realtime, rather than doing so on a case-by-case basis or only every so often, as in XP.

If I remember what it's called I'll post back.

mods, please move to general h/w, no longer seems s/w related cheers
