A:AnswerNot sure, best to call them and double check. A word of caution with this unit. Very sensitive to lightning. Mine died just 6 weeks after purchase. Out of the warranty period of 30 days. Recommend what ever modem you go with, the addition of a lightning surge/arrestor, that is added to your cable input just before the modem.
A:AnswerOnly canles are a power and small ethernet cable. Comcast will supply if you need one, but you should go to the comcast outlet and get one.
You can pick up a cheap RG6 coax cable anywhere, like best buy in the tv section.
