I have a linksys WRT54g (v2) router and i want to adjust my MTU but i have no idea how. anybody know?

I know zip about this since I'd never heard that acronym before, but this site seemed pretty informative if not a good starting off point.

Hi Rifletank

Adjusting your MTU (Maximum Transmission Units) is something that should not be undertaken lightly. The default setting for an ethernet interface is 1500 this being the ethernet frame size. Excessive fragmenration can occur if the setting is incorrect. An ethernet frame is nominally 1500 octets in size while 576 is the max for a slip connection (used by WinSock). Don't forget to account for the header when calculating a new MTU.

Incorrect MTU will result in a slow down of your network. Good luck. BF

in other words, is adjusting (raising or lowering?) the MTU is kind of like OCing my router/modem?

Hi Rifletank

No, that is not how it is. Rather it is more like selecting the right sized box for the goods that you wish to send. If the box is too small the goods need to be cut up and put into several boxes, while if the box is too large then there is a lot of wasted space.

Both scenarios result in a slow down of your network connection. BF

BF that's a great analogy. Makes it simple to understand.

what would be a good number to set the MTU at to get the best speed?
and going to my original question, how would I change that number?

Hi Rifletank

1500 is usually the best for an ethernet network. How you change it is a function of the operating system that you use, and details of this are contained in the original post by Dashwood using the DR.TCP program or by use of registry edits for later systems. BF

I'm set to 1492 because I am on a DSL connection and because that is what D-Link 2nd level tech support told me to do.
