vista-64 network question

[toreses]

I am using vista-64 with comcast networking
but in these days I found when my download speed is high maybe 700-800K/s
when it last for couple minutes, my internet is disconnected
I have to restart my moderm, I try to restart PC first, it does not work
I search on online, someone says that may be the problem from IPV6
because xp is using IPV4 and vista now also comes with IPV6, but IPV6 is not popular now
I try to disable IPV6, but it seems my internet speed is slower....
do you guys have any opinion for this case?

I doubt that IPv6 has anything to do with it.

In any case you can Uncheck IPv6 in the Connection Properties.

Other optimize the TCP/IP Stack.

I just disable the IPV6 in the connection properties
and the speed stays the same.
is it that all?
what do you mean by the Other optimize the TCP/IP Stack?

First read this.

Optimizing the TCP/IP Stack - http://www.ezlan.net/Internet_Speed.html

However the Utility mentioned in the page is only for Win XP.

For Vista use this (TCP Optimizer).
