MTU Size in DSL Router AND speed [modified]
-
If you are having slow download speed in you cable/DSL try changing the MTU size to 1500. You may see improvements of 20 Times. Just thought I will post that in the forum. -- modified at 22:24 Monday 11th June, 2007

Did you use the thumb wheel adjustment to change this. Or is there a magical command that the modem will respond to perhaps? :confused:

It's a registry setting. Can't remember where, but I'm sure google can find it. :) Marc

Wooo, so if I change my MTU from 1492 currently to 1500, my 1.5MB (megabyte) ADSL link will suddenly give me 30MB/s??? cool! :-D

Typical you have to log into management console using class C Ip address like 192.168.1.1 or 10.10.10.1 for Ciso PIX and stuff like that. It is the Riuter seting for LInksyss/dlink/Ciso/Netgear kind of Router and Firewall. you can check your speed using simple test like http://www.speakeasy.net/[^]

Uh... exactly how is changing the MTU above the actual path MTU supposed to help out here? DSL's 1492 MTU is due to the ISPs setting it up as a PPPoE tunnel, so you have an IP packet inside an IP packet. This adds 8 bytes to each packet as its sent down the wire, thus causing the 1492 byte MTU that you see. Plus, remember that connections also follow an ICMP path MTU discovery protocol, and limit themselves to the smallest detected MTU between the two end nodes anyway.

There you go again, trying to counter urban myth with fact. Will you never learn?

Actually MTu Sidde is ISP specific. So you have to experiement to get an exact value for your situation.

It's a setting in the ADSL Modem/Router, don't know of it being in the registry but stranger things have happened.
