Windows 7: Windows 7 RC - network consuming

Hello all,

I have an strange issue here. I have connected 1 server to internet (using linux) then server connected to a 1Gb switch, 1 computer with windows 7 RC connected to that switch and wireless router also connected to that switch.

Everything is working correctly exact when I start to download something on my windows 7 RC machine. Then my notebook connected by wireless going to have >1000ms response from my server. If I stop the downloading on the windows 7 RC comp then the response is going back to normal (1ms). I tryed also to emulate windows xp and red hat linux on vmware under Windows 7 RC and try to download something - it's working fine.

Also it is enough to just run mozilla and browse to get >50ms response from the server on my notebook.

I'm using Windows 7 RC build 7100. I have an ASUS L1n64 sli ws/b mainboard with Nforce 680a SLI chipset. Also have installed the latest drivers.

Anyone who have any idea?



Thanks
