168.0.1
If you still get an error, try:
ping -f -l 1454 192.168.0.1
The numbers in each of these examples (1500, 1492, 1480, and 1454) are
values for the Maximum Transmission Unit (MTU). Continue issuing
this command with lower and lower MTU numbers until you get normal
ping responses instead of an error message. The highest MTU value
that does not result in an error is the correct one for your network. It??™s
not unheard of for an MTU as low as 576 to be required, although
Microsoft recommends no value less than 1,400 for Windows XP.
3. Once you??™ve found an MTU that works for you, open the Registry Editor
(see Chapter 3) on the client machine.

4. Expand the branches to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
Services\Tcpip\Parameters\Interfaces.
There should be several subkeys under the Interfaces key; most likely,
you??™ll find three. View each key??™s contents, and find the one that corresponds
to your primary network adapter; it will be the one with more
values than the other two, and will have an IP address value set to the IP
address of the machine.
5. Once you??™ve found the correct subkey, create a new DWORD value in it
by selecting New and then DWORD Value from the Edit menu. Name
the value MTU.
6. Double-click the new value, choose the Decimal option, type the MTU
value you determined earlier in this procedure, and click OK.
7. Close the Registry Editor when you??™re done; you??™ll need to restart Windows
for this change take effect.
