I'm using an Ethernet Arduino board.
I've downloaded a code that uses the ERxPachube library to upload data to Pachube.
In this code, I didn't use DHCP, I assign the IP address manualy.
It works but at some point, the connection is lost.
Any information about it wiuld be usefull for me.

You're going to have to post some code. What have you tried already?

Here is the code I use :
/*
Pachube Data Out

Demonstrates use of the ERxPachube library.
Push local sensor data to Pachube server.
If you don't have a Pachube account, register one first (http://www.pachube.com/).

To run this sketch, you need:
 1. Create a same feed as http://www.pachube.com/feeds/23408
    (A manual feed with three data streams with ids 0, 1, 2.)
 2. Use your API key to replace the space holer PACHUBE_API_KEY below.
 3. Use your feed id to replace the space holer feed id 23408 below.

Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13

* Created 22 April 2011
* By Jeffrey Sun
