Hey there, I have a question. I saw you post on a problem similiar to mine
http://www.cablehack.net/forum/comca...od-work-2.html
Basically I tried to change the HFC mac to one of the ones from list of macs and changed the Ethernet mac as well except for the last number I changed it to up 1, I then put the config file and saved it all and nothing. I tried to change the hfc mac only and nothing I started only putting the config file and not changing macs and nothing, I tried 4.2.2.2 it is set to 208.67.222.222/208.67.220.220 I tried 68.87.72.14 as the tftp server and nothing. I tried load config from tftp and nothing and left it at load config from isp and nothing. When I do change to dns automatically I get the comcast start up screen. I am stumped any help is greatly appreciated.
