Should of done this years ago
I'm not sure why I didn't buy a modem years ago. Time Warner was charging me $8/month to rent theirs. I bought this modem to save money and I'm glad I did. Modem works great. It's fast and very compact about 1/2 the size of the modem I was renting. I'm very happy with the purchase and would recommend this modem.
