This is what i get what am i supposed to do?

S7R1D3R;If you have DSL your MTU is probably 1492 so 1492 - 28 for the headers =1464 so try 1464.

If you have cable check to see what your MTU is.It should be 1500.

Even if Windows has the correct MTU some modems & routers change it so you need to check their settings as well.

But if you have DSL try the 1464 first.

You acn see what the tcp/ip analyzer says at speedguide.net.Some people it works well for & some not so well.I know it doesn't work for satellite.

ok it worked this are the results:

Yeah, for satelite I use the Rev's settings on the TCP Optimizer.

It works great!

S7R1D3R;This tells me that your packets are not fragmenting at a mtu of 1492.So your connection settings are for DSL.Your not getting any packet loss to testmy.net with ping at this MTU.Your average ping time to testmy.net at you max mtu is 162ms.

You can use this to any site that allows ping to see your average latency to that site at your max mtu.If you just use ping without a byte number it only uses 32 bytes.So the latency will be a lot less but not as accurate for your OS's latency.
