My brand new iMac running Mac OS X 10.7.3 loses internet connection after computer wakes up from sleep.  This is not a WiFi problem because I am plugged in with ethernet.  It loses its connection roughly 50% of the time it wakes up and then I have to go through the diagnostics and reboot my cable modem and router.  It is very frustrating.  I have tried renewing the DHCP lease but the problem continues.  Has anyone encountered this problem and what did you do to fix it?  Thanks in advance.

iMac, Mac OS X (10.7.3)
