Hi,
Considering this issue occurs on 2 different machines, I also think this issue may be more hardware related. You may also try the following:
1. If the computers are connecting to a router, please ensure the router’s firmware is up-to-date.
2. Please run the following command in an elevated command prompt in Windows 7:
netsh interface tcp set global rss=disabled
netsh interface tcp set global autotuninglevel=disabled
netsh int ip set global taskoffload=disabled
3. Disable SNP in Windows 7 by setting Registry as following:
Note: Please perform a full-system backup first.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters]
EnableTCPChimney=dword:00000000
EnableTCPA=dword:00000000
EnableRSS=dword:00000000
If the keys do not exist, please create them and assign the value.
An update to turn off default SNP features is available for Windows Server 2003-based and Small Business Server 2003-based computers
4. If the issue persists, please add another network adapter to this computer and see how it works.
Hope this helps. Thanks.
