ndisuio.sys and serious performance problems
« on: July 29, 2011, 06:22:55 pm »
I was running qBitTorrent on Windows XP and noticed serious performance problems with my internet connection. Looking at the firwall logs I notices a lot of, really a lot of packet being blocked, they all were for ndisuio.sys. So I googled this file and decided to deactivate the corresponding service. Helped immediately. I do not have WLAN hardware on my PC anyway, I do not even know, by what this was activated. I must be getting old.

It's the Wireless Zero Configuration-Service. You find it under the control panel, administration tools, services => Wireless Zero Configuration

German: Konfigurationsfreie drahtlose Verbindung
