I have have this install on Comcast -lrb- North NJ -rrb- for the last week . so far it be work fantastic , operate well above what I would have expect to get off Comcast 's network . that be say it do appear to be somewhat sensitive to signal issue . I have to have a Comcast tech come out and help trace out a wire because the modem would go squirrely around 9:30 or 10 every night and then start work in the morning . we located and remove 2 splitter which have clean up the signal strength issue -lrb- it be run at the top of the spec would strength for outgoing and incoming message -rrb- . hopefully thing continue go well !
