Internet setup

Even if I'm not a specialist I will try to explain, I hope some  
peoples with more knowledges in this kind of stuff will say if  
something is wrong.

The mtu is the number of byte contained in one paquet sent over a  
network.
Changing the size sometimes improve your connection because the  
paquets sent this way are then smaller and then do not need to be  
split up or less need to be split up.
Normaly the MTU by default is at 1524 bytes or something like that  
(sorry I don't have the number in mind...).

Regards

Johann
