How to speed up your 802.11n connection

If you've upgraded your wireless networking equipment to the latest and fastest standard, 802.11n, you may not have experienced the performance boost you were expecting, because by default, Windows XP is not optimized to handle the processing of the data as more bits are transferred between the WAP and NIC. You can edit the registry to turn on a feature called Receive Window Scaling that will speed things up. As always, back up the registry (use the File Export option) before making changes. Here are the instructions:
Open your registry editor.
1. Navigate to the following key: HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters
2. Right click an empty space in the right details pane and select New DWORD value
3. Name the new value Tcp1323Opts
4. Double click the new entry and give it a hexadecimal value of 3
5. Again, right click an empty space in the right pane and select New Dword value
6. Name the new value TcpWindowSize
7. Double click the new entry and give it a hexadecimal value of 40000
8. Reboot your computer to force the changes to take effectYour network adapter should now perform faster with 802.11n routers and WAPs.

How to move the Public folder to a different drive

Vista has a folder named Public that you can use to share files with others on your network, or others who log onto the same computer with a different account. It's handy for that, but some folks want to move it off the C: drive (its default location) because that drive is getting full. You can do it by editing the registry. Here are the steps for moving it to the D: drive (substitute the appropriate drive letter).

  • First back up the files and folders in the Public folder by copying them to another location. Before copying them, in Explorer click Tools Folder Options View and select Show Hidden Files and Folders, so you can be sure that you copy all of them.
  • Now open the registry editor and navigate to the following key: HKEY_ LOCAL_MACHINE \ SOFTWARE \ Microsoft \ WindowsNT \ CurrentVersion \ ProfileList
  • In the right pane, double click the key named Public
  • Change the data value to D:\Public
  • Reboot the computer
