I found this little tidbit and was wondering if anybody knows if its a valid internet speed tweak? Supposedly sites load faster..


Go to Run, and write:
cmd.exe "enter"

c:\>netsh "enter"
netsh>routing
routing>ip
routing ip>dump

And then it will list off a whole bunch of need stuff.
If you scroll back towards the top of the dump,
you'll notice this little line:
( set filter name="Local Area Connection" fragcheck=disable )

It's a packet defragger. Why it's disabled by default is beyond me.
So here's what we do:

ruoting ip>set filter name="Local Area Connection" fragcheck=enable

And you should be good to go...

Just enabled it on mine. But the connection is already so fast, I can't really notice a difference. Perhaps someone with a lower bandwidth connection might see a change.
Anybody?

wouldn't checking to see if packets were fragmented actually slow your speeds as there is more overhead?

Hi there!

This is my first post. Congrats to everybody with a great forum. :)

I have been testing this tweak on a 1-way satellite system with 1 MB/s in a LAN, for about two weeks. On the LAN interfaces I cannot detect any change in speed. On the DVB interface though, I have a consistent speed increase of about 2% max. In bad weather conditions, this increase can be close to 6%.

Can any sat users confirm this? Also, there doesn't seem to be any info on the enire web about this particular command. If anybody has any information, please post it. :cool:

As long as you set the MTU, MSS, and receive window sizes correctly, fragmentation shouldn't be a problem.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS

Been running around Quora lately, luv it there https://tinyurl.com/ycpxl
