    Had to return it the same day I bought it. As of the day I purchased it, it is not supported by WOW internet. Only reason why I give it 1 star, was unable to use and objectively evaluate. I have owned ARRIS modems previously.

    It took me a couple weeks to find someone to install this item and I found out it wasn't the correct item I could use but it was too late to return it so I have a brand new modem I can't use.
