RCA's latest DOCSIS 2.0 certified cable modem, the DCM425 is future-proof and supports up to 16 upstream flows in silicon and represents a further improvement of DOCSIS product-line in a small form factor. The 16 upstream flows allow operators to provide tiered data services and support more efficient traffic prioritization schemes for telephony. Not only does the cable modem allow symmetrical data transfer, and tripled upstream throughput, but the modem integrates Broadcom's Propane technology, enabling the connection of more Internet users without additional bandwidth. RCA's case design is consistent throughout its product line of cable modems and gateways.

I am getting ready to turn in my third one of these to Mediacom. They keep issuing this same modem and the modems crap out between 6 to 12 months. They start by sporadically dropping the connection and resettting and finally won't connect at all.

For the people saying that this is a good modem, must not be using the internet at a constant rate. If you are a hardcore internet user like me, where you are constantly downloading, gaming, or web-browsing, then do not rent/buy this modem. You WILL have your internet connection dropped constantly. I have to unplug the cable modem about once every 30 minutes then replug it back in to get my internet to working status. I've called Comcast to make sure it's not something on their side and it's not. It's not my computer either because I used to get download rates tremendously high and no dropped connection before I moved about 2 months ago. After purchasing a my own cable modem instead of renting this one, I have had a large increase in my speed and have had no dropped connections.

I don't know why so many people are having problems with this unit-it does very well for me.
The stock power supply may be at fault here. I connected this using my old Toshiba's cable modem power supply.
It is rated at 12 volt DC @ 1 amp and is of the linear regulated type.
The AC adapter supplied with the RCA is one rated 9 volt DC @ 500 ma and is a switching type.
I believe it may be the underlying cause to all these problems because my RCA has been rock solid reliable and fast.
However, I do not own this unit, it is supplied by Time Warner Cable. If anything goes wrong with it, I bring it back and get another-simple!

With this modem have had average speeds of about 8 mbps downsteam and 750+ kbps upstream. After only three months of servive, this started having serious connectivity issues, slow speeds and dropped connections. After a few weeks of this, it failed to connect at all. Further investigation revealed that two capacitors had died. Replacing these using high quality parts with doubled capacitance value, I now have average speeds of 10 mbps down, and 800+ kbps up. These speeds are on par for the service I subscribe to. I am currently shopping for a replacement, no telling how long this will last.
