Diagnose and repair: Turn on tcp performance improving settings?

[ChehZaad]

This is a Windows Vista laptop. Due to some reason yesterday I needed to run "Diagnose and repair" in Network Sharing Center. Everything worked fine yesterday. But today when I started the laptop I got a small pop up window saying:

"The TCP setting needs to be adjusted to improve network performance."

There was a button on this window saying “urn on tcp performance improving settings.” I clicked the same but nothing happened. In it didn’t appeared again. However everything is working good, I would like to know what was that error about and which TCP settings it was talking?

It is normal to have such message once in a while. You don’t need to bother about it. It is actually just an optimization setting for your router which use to be enabled always and keeps running in the background. I think while running "Diagnose and repair" it may have got turned off and to turn it ON again, it gave you pop up.

Hi Charlene,
Could you give a bit more technical detail about the actual router optimization made?
Thanks
