I have consistent network activity on one of two dns323 boxes, even while there is no drive activity. My transfer rates are about 10% of the rate for the box with no network activity. Both boxes have no dhcp server, no add-ons, no itunes server, nonUPNP no FTP, and no items in scheduled download/upload. I have had this same problem with an older DNS323 which has I replaced because of same issue. It also makes restart slower (?`6 minutes). Any ideas?
