Highly recommended for Time Warner users in New York

Like many others I paid Time Warner $10 a month to rent one of their modems as I had enough trouble getting the internet up and I wanted to not to bother installing my own. When I saw this modem for sale, I gritted my teeth and ordered it, fully expecting to spend a day on the phone with Time Warner. Surprisingly, installation was incredibly easy - I unplugged everything and replaced my old modem with this one. , and turned the wireless router back on and everything was (mostly) set up. Time…

Buyer warning! - Computers and accessories

  • Sturdy construction
Cons
  • Approximately

Not only did the product not last (83 days), Arris as a company completely lost my business. On top of the mostly terrible…

Pros
  • There's something there
Cons
  • No automatic

Super easy install with Comcast

I was looking for a DOCSIS 3.0 cable modem to get rid of the $10 a month rent on a family member's bill and came across this refurbished unit at Revain for less than half the amount time of new purchase. After much deliberation about whether to buy a new one or a used one, I decided on this one. Received the device (same day), connected to the PC, opened the browser, went to the Comcast activation page, entered the credentials and the router was set up and registered within 5 minutes! I…
