*Maximum speed varies depending on the service provided by the cable operator.

** IPv6 availability is dependent upon your ISP or Service Provider providing IPv6 capability.

Linksys DOCSIS 3.0 Cable Modem (DPC3008-CC)

After a great deal of research for my circumstances, this specific cable modem is my best available option as a "supported device" with Comcast, my Internet Service Provider (ISP). Amazon Prime offered a competitive price (since increased). The order arrived on time along with another Amazon order placed later that arrived a day early.

If you are a basic internet service consumer, you probably are not shopping for a DOCSIS 3.0 cable modem. If you want the best "bang for your buck" and need fast internet access say for video on demand or online gaming, read on.

Bottom line, this Cisco DPC3800-CC cable modem works on my Comcast service. It does not operate at DOCSIS 3.0 speeds. My quantifiable thru put is now more than doubled by replacing a leased DOCSIS 2 cable modem with this DOCSIS 3 modem. The pay back is 12.2 months by eliminating the Comcast modem lease. My disappointment rests with Comcast, not this product. Here is why.

While the FCC wants US ISPs to make 100 million bits per second (100 Mbps) download speed our national standard by 2020, we are FAR from that standard in 2012. A cable internet provider that implements the full feature set of the cable industry's DOCSIS 3.0 standard could meet the FCC objective. But my service provider is not even close and has no incentive to do so. All we can do, as consumers footing the bill, is to be informed (search "DOCSIS 3.0") and purchase products that will work if the service level is provided.

This modem drops connections and/or get hung up constantly. It gets hung up and reboots itself several times a day. Sometimes I have to manually reset/power cycle the modem to get it back up and running again. You should NOT have to manually reset or power cycle your modem 2-10 times a day, especially a brand new modem. Tried troubleshooting with Comcast and was referred to Linksys Tech Support, who then tried to refer me back to Comcast. After telling them that Comcast referred me to Linksys in the first place, they tell me it is beyond their scope of expertise and referred me to Cisco Tech Support. Cisco Tech flat out said that they couldn't do anything for me or my problem since there is nothing configurable on the modem. I asked if the modem was faulty then wouldn't Cisco have to replace it under their 1 year warranty? The Cisco Tech said there was nothing they can do to help.

This problem with constant disconnects affects a lot of Comcast customers and the only fix seems to be have the firmware flashed back to the Aug 2011 because the Jan 2012 firmware is faulty. Unfortunately, none of the tech support people that I got in touch would was knowledgeable enough to help. Of the two Linksys and Cisco Tech I spoke to, neither was able to even give me the default password for the Modem status page.

The DPC3008 maybe Certified by Comcast but neither Comcast nor any part of Cisco or Linksys will provide support for it.
This modem doesn't have a log page to see what went wrong and there is no interface or even download site for the user to change the firmware.

Also, when the modem is hung up or if the internet status is disconnected, there is no way to reach the modem status page through a browser via the IP address

I have grown to be a fan of Linksys / Cisco product s for a while. I kept getting calls from Comcast stating that my current purchased cable modem is no longer supported, and they would be happy to send me a new one free of charge, but of course, add the $7 per month rental charge. I work out of my home and had noticed my VOIP calls, and downloads were not as fast as they should have been after I analyzed my current system. I went ahead and purchased this product due to it being a Cisco product, and it being certified by Comcast.

After receiving the product, I ran with the modem for almost a month and speeds down and up were fantastic. My VOIP calls were clearer, and streaming and video calls were much smoother. However, I noticed that the modem would randomly drop the signal, and re-synch up again. The modem was in a open area, so I new it wasn't a heat issue, nor did the unit ever become hot. I called Cisco support, who directed me to Comcast support, as they claim it was a firmware issue that Comcast would manage. I checked online, and in the Comcast forums, I found others who also had the same issues. The current firmware release from January 2012 was the issue, and the only solution was for Comcast to roll-back the firmware to an August 2011 release. After almost 10 contacts (phone or chat support) with Comcast to report the issue and direct them to their own forum, the firmware was never rolled back, and the issue did not go away. I had to inevitably send the product back to and replace with a Surfboard SB6121. It's an alright modem so far, but upload speeds not so good as uploads are only bonded to one channel. I'll report back if something goes wrong with this new modem.
