TWC gave me this RCA DCM425 DOCSIS 2.0 modem when I first signed up for their service 4 years ago and it never let me down. Since it is small and unobtrusive, I figured it was somehow inferior to other fancier cable modems. So, when TWC announced that they would start charging a modem rental fee, I decided to buy my own and go with the big gun most recommended by TWC - a top of the line Motorola Surfboard (SBG6580). The Motorola was bigger, sexier, and touted as a DOCSIS 3.0 powerhouse that would increase my speed and throughput. Unfortunately, I started having trouble with it from Day One - my speed was lower, websites timed out, and I was suffering 40% packet loss. When I ran a speed check, the speed was fine (as advertised) but sites weren't opening, YouTube was lagging, and my overall throughput was miserable. TWC tried and tried but couldn't figure it out...all the way up to their Tier 3 support level.

In the end, I found my old friend, the RCA DCM425, here on Amazon and decided to try things the way they used to be. The RCA was a breeze to set up and after a short 8-minute phone call to TWC to have them activate it...BAM! My internet was back to the way it was - fast, smooth, and awesome! No lags, no time-outs, no headaches. Sometimes simple is better. DOCSIS 2.0 is fine for me and the Surfboard's going back. Perhaps it was just a bad unit but TWC didn't seem to think so. In any case, I'll stick with my reliable RCA.

4.0 out of 5 stars Can't beat the price
Reviewed in the United States on December 29, 2012

This is a bare-bones cable modem with no configuration options supporting up to DOCSIS 2 (i.e. not for gamers who need high-speed). I paid $15 for this cable modem to replace my rental modem. It has worked great for the last month. I did have to set it up again but I was trying to set up an Obiphone and I may have messed with the configuration. I am about to cancel my modem-rental contract and save some money.

The key is to follow the installation process that other reviewers have posted: 1) unplug everything 2) connect the cable to the modem and plug it in 3) connect your computer to the ethernet port of the modem and try to get to the Net 4) go through Comcast's process for connecting your modem 5) connect your router (you might have to reset it)

Like most customers apparently, I ordered this RCA DCM425 broadband modem to get out from under the monthly charges for renting a modem from Comcast. It's billed as the same one used by Comcast... but it's NOT! I found, to my dismay, that when I went to swap it out for the Comcast rental RCA unit, the new one from Amazon lacks one vital feature: a telephone output port. We recently bundled our services from Comcast and now take TV, broadband cable ...AND telephone from them. But, without a telephone port, I'm going to have to return this one to Amazon and look for one with all the ports I need. BE CAREFUL, BUNDLERS!

i received my rca modem, fast delivery, great packaging,love how it looks, spent about five minutes with comcast tech support, gave them my mac number and model number, then he sent a test signal to see if my rca received it, worked immediately, after getting off the phone, i connected my router and vpn, it may have taken ten minutes cause i was trying to see if it would work without calling comcast, but now i am very happy, i am using windows 7 with an acer desktop phenom quad core, the manual does not list windows 7 compatibility but after reading the reviews one person said it works with windows 7 so I took a chance so glad I did, if you have a big pile of cash and want to keep paying for a rental unit, ok, but if you are trying to save? check this little modem out, this modem is faster than my comcast modem.

3.0 out of 5 stars Good unit...Bad Cable Company
Reviewed in the United States on November 19, 2012

The unit works great BUT it s the same inexpenssive unit the cable company sets for their installs SO get set for a hassle with your provider. The cable company I have service through only recommended 5 units...naturally the most expensive. When I bought this unit the tech rep tried to tell I couldn't use this unit because they would have to approve the MAC address and this wasn't their approved unit. After going through 5 tech reps and threatening to sue I finally got them to approve the unit. The unit works great and I have had no problems but keep in mind that the cable company has the ultimate say.

5.0 out of 5 stars Great modem but no longer suppoted by Time Warner!

TWC just fried my modem last week, supposedly during one of their updates. I had owned it just over 3 years, to stop paying lease fees. Tech came out today and replaced it with a TWC modem which I will promptly replace as soon as my new purchase arrives from Amazon. Looking on the TWC website, this RCA modem is no longer supported, so I cannot replace it with like item. Make sure your cable provider supports before you buy!
I ordered the exact cable modem that Time Warner has supplied me with for years and has just started charging a lease fee of $3.95/month. Since I have to battle with them every 2 years to lower my monthly bill to retain me as a customer, no way was I going to pay that lease fee. My purchase will pay for itself in a year. I did not feel the need to purchase the more expensive models that TWC listed as compatible on their website-these were $77 and UP! I did online chat rather than sit on telephone hold waiting for a rep, someone came online with me in less than a minute. Though the whole conversion process took about 30 minutes as she verified my account, obtained MAC number, etc, online chat worked great for me. I could walk around and do other things and just kept an eye on the chat summary. The new modem is in place and all is well.
