Do you have an idea what is doing that ? I have removed apmd services and everything that concerns energy savings ! Thanks for all your tips :)

Vince,
Try turning off auto-negotiation on your Ethernet card. Set it to
100Mbps full duplex or 10 Mbps half duplex. I had a similar problem
with a realtek card. I think it was an 8139. It did not negotiate well
with a dlink router.
ethtool or mii-tool should help determine which works best, then add the
appropriate option to /etc/modprobe.conf. I could not find a definition
of realtek's supported kernel parameters in /usr/share/doc/... Maybe
google.
It could be related to power management. I have had similar issues on my old Pentium II when left unattended for some time. To solve my problems, I just did:
chkconfig apmd off chkconfig acpid off service apmd stop service acpid stop
