Modem work as expect with no issue . my isp provider -lrb- bresnan -rrb- be finally upgrade to DOCsis 2.0 so I have to upgrade my old Linksys modem to one that support it . I simply unplug my old modem and replace it with this new one and then call my isp service department to give they the new MAC address . once they configure that on they end , I be back online and have have no problem since . I have almost always be satisfy with linksys product and use they often with little to no complaint .
