Windows 7 64bit Network Freezing

So, had a issue where my laptop which is running windows 7 64bit and the network was freezing copying large files.

On the laptop

• ipv4/ipv6
• virutalbox
• citrix access gateway plugin

The symptoms were large copies were freezing with 0kb/s

removed virutalbox and able to copy files again.

If i get time to investigate then look into if issue between CAG plugin and Virutalbox.

Update:

so the problem came back for some reason, also seems my virtualbox didn't uninstall correctly.

a. Running as Administrator in Command Prompt, type: "netsh int tcp set heuristics disabled"

b. Next, follow the instructions that Amrita wrote above.

                  First enter: "netsh int tcp set global autotuninglevel=disabled" and reboot.

2. mucked around with the settings in intel network card properties (latest driver)
