Summary: I bought this wireless modem to replace my old one (which I had bought used). The old one had a low power output, according to my spectrum analyzer. This new one works great. The output level is correct, and it roared to life as soon as my cable service provider registered its MAC address.
Summary: The cable company wanted me "rent" their modem for $11 a month so I read up on modems. This model was highly recommended. The cable guy asked me if I had my own modem & who I was using for cable at the time (I was moving & Time Warner was all that was offered at my new place) I told him I had previously had Comcast & he said that my modem from them would work with Time Warner. He also said it wouldn't work with At&t or Dish, Direct Tv, etc..
