connection speed

[Paul]

Are there any tweaks that can be made to either Windows XP or router
configuration to improve the performance of a broadband connection?

There are plenty of utils that change things like MTU and TTL but do they
really make any difference?

I've heard of SNR which by all accounts can improve speeds but is this
something that's dealt with by the carrier and handled automatically by the
router?

Does anyone know? There's so much anecdotal waffle about, I'm trying to cut
throught it!

Thanks

Paul

MTU should be 1500 for cable, and I think 1476 for DSL. But the
parameter that makes the biggest difference for broadband is the "TCP
receive window". Try setting it to a very high value.

Good luck, jimbo

Where is that key to be found, please? I am not a Reg. wizard and
searching turned up nothing here.

Try setting it to a very high value.

Approximately, how high?

And what would the default value be like?

Good luck, jimbo

Paul,

SNR, or Signal to Noise Ratio, is an analogue issue. If part of your broadband
service, it is something that you must trust your ISP to resolve. In general,
the broadband signal that carries your Internet service is their responsibility.

SNR can also affect your WiFi speeds, if WiFi is part of your LAN. There are a
myriad of tweaks that you can make to WiFi, most of which will affect SNR there.

MTU and RWin are settings that you can make. Both will make a difference, if
improperly set. I've written about MTU.

The Receive Window, or RWin value, you must make based upon the speed and
stability of your Internet service. DSLR Forums has a tool to help you tweak
this setting.

For information about TTL, which doesn't really affect you as greatly as the
settings discussed above, I give you WikiPedia.

We can advise you further, if you will be more specific about your concerns.

You need a utility such as DrTCP or Tweakmaster. My Win TCP Receive
Window is set at 256,950.

Good luck, jimbo

Thanks, great!

I don't really worry, it seams fine here - but I also don't mind tweaking
for that little extra. It usually happens those days when traffic is like
swimming in jelly!
