i have Docsis 2.0 from Scientific Antlanta Webster Modem which i want to use for internet with my subscription to Multichoice Dstv. i also have a 5 way coax splitter. i have connected the coax cable that comes from Dish LNB to the IN port of the splitter then i have connected the Decoder with the splitter as well as the Cable modem. but unfortunately the signal goes down but when i remove the Modem the TV plays. From what i know the LNB is powered by the Decoder so if i remove the Decoder then it will be no signal being sent to the Modem. i cant figure out how can the Modem work and i asked and he said that the signal comes from LNB encrypted then the smartcard decrypts it so the modem does nt have the decryption key. i thought maybe the power that is being sent by the Decoder to LNB wont be enough if the Modem is connected but i cant figure out how to solve that. if someone knows please help!!!
