have I find this comcast forum post at -lrb- ... -rrb- , I would not have buy dpc3008 . Cisco DPC3000 work fine earlier . now , I have no support for resolve drop connection issue with this dpc3008 . Comcast keep reset and tell no log of any disconnection activity . Cisco on the other hand be not tell what be with the firmware that people be talk on the Comcast forum . both company need to figure out the fix to this problem soon . update -lrb- April 18 2012 -rrb- : Comcast revert back the firmware build date to Aug 11 2011 and it fix the drop connection issue . definitely , this would change my opinion on the product to excellent .
