Tips to Speed up Windows 7 Network
First, check the Network Interface Card (NIC) configuration and the Network port configuration to make sure that they are synchronized properly. Sometimes the Windows 7 network is slow because one of these components is ill-configured. Also, if the auto negotiation between the NIC and network switch doesn't work properly, the NIC may use different settings that will still allow data flow but restricts its rate. Thus, to speed up your Windows 7 Network, the NIC configuration and Network port configuration should always be in sync.
Another thing to try is that you can also disable autotuning. This helps in saving time on DNS and network discovery. To disable autotuning in Windows 7, open the command prompt (type cmd in Run dialog). In the command prompt, type the following:
Netsh interface TCP set global autotuning=disabled
You can check if the autotuning is disabled by typing the following:
Netsh interface TCP show global
It should show the value of Receive Window Auto Tuning Level as Disabled.
One final thing to try is to clear the DNS cache. To clear the DNS cache, type in IPCONFIG /FLUSHDNS in the command prompt.
