This happens with my Toshiba Satellite A80-154 laptop too. It has Marvell Yukon 88e8086 Fast ethernet controller. Moreover, i connect my system in office lan, so it has a static IP. And in many posts people mostly complain about DHCP and the network problems occur because of the DHCP. But this happens with static IP too. I actually upgraded from Breezy to Dapper, thru update manager. I never had this problem with Breezy. Since, I suspected that anything wrong might have happened during the upgradation, I checked with LIVE CDs, still the problem persists. And I tried installing XUbuntu on another partition just to check.. The network has the same problem!!
