I purchased the combo through Amazon. As soon as the window closed to return (1 month), it started dropping connections. After 6 service provider visits and nothing was resolved because the modem router would work and as soon as the tech would leave, it started dropping connections. Sparklight cannot update firmware and Arris won't. This is the only item that I have purchased from Amazon that is absolute junk and not cheap. NO ONE will address this issue.
