Network Transfer slows down

Vista has a built in TCP/IP autotune feature- That is what makes your network transfer slow down so much.
I don't know all the details, but have seen this b4- Do a google search for vista autotune- It will tell you how to change the settings and I think you can even turn it off.

    tcp set heuristics
    disabled
    
  • 
    netsh
    int
    tcp
    set global
    autotuninglevel=disabled

Network bridge suddenly stopped working in windows 10

Hi Shantanu,

To isolate your concern, we would like to know how your network bridge is connected? Is it a wireless connection or a wired connection?

In the meantime, we suggest that you set up your network bridge to refresh the adapter and reconnect the other devices. To do this, follow the steps below:

• Add Incoming Connections from the Internet.
• Bridge the two network connections that you want to use.
• Forget the internal network connection (under
  Manage Known Networks).
• Reconnect to your bridge network.
• Restart your computer and check if your concern persists.
  

Let us know if you need further assistance.
