Note: Please note that you can cause damage to your system if you make a wrong move when editing the Windows Registry, so you do so at your own risk. Back up your registry before attempting to use any of the registry tweaks.
The TTL value in the registry specifies the number of hops that a TCP/IP request can travel through before timing out. The default TTL is 32. If you ever have trouble connecting to a host that is more than 32 hops away, you can try increasing the TTL to 128.
Step 1: Open up the Windows Registry Editor. To do this click on the Windows Start button, click on "Run" and type in "regedit" before clicking "OK".
Step 2: Find the following registry key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Tcpip\Parameters
Step 3: Look for a DWORD value named "DefaultTTL". If you don't have this then you will have to create it (see screenshot):
Step 3: Once you have located or created "DefaultTTL", you need to set the value of this. Set the value to "128" (without quotes).
Step 4: Close the registry editor and restart your computer.
