* Every time you send a 1500 size packet out on a MTU1492 network you end up with two packets: 1492 + 8. That's why the speed drops - The second packet is almost empty! If you type:

ifconfig eth0

* It will show:

MTU = 1500

* The standard MTU<ref>:maximum transmission unit</ref> for DSL and cable is 1492 maximum, for DSL via PPPoE<ref>:Point-to-Point Protocol Over Ethernet</ref> it is often 1480 (you best ask your provider for the correct value). You can:

* Add the following line to one of your startup files in the ''start'' section, e.g. in
/etc/init.d/networking

/sbin/ifconfig eth0 mtu 1492

<center>'''OR'''</center>

* Add "mtu 1492" (a line by itself) to
/etc/network/interfaces
