Hi! 

 
I&amp;#39;m developing a project and it&amp;#39;s working well at 10Mbps
( _10MBIT_ define at LPC23_EMAC.c) with TCP protocol. The ping
response is perfect: 

 
ping 10.0.0.180

You should check the capabilities of your hardware. The Ethernet
PHY is a separate chip on your board. It may or may not support
support link speed autonegotiation. It may support 10 Mbit/s only.
Look up your Ethernet PHY part number and download the datasheet.&lt;/p&gt;
