This is on Comcasts approved device list but is there anything that would prevent using it on their network? Config'd for Cox or TWC?

If it is used and still registered to previous account, it can't be used. The config files are pushed down when the modem is connected and activated. The 3008-cc model was made for comcast

When I called to connect it, I was told that the modem was already registered with a Comcast account and I couldn't use it. Luckily, I called back and got a different technician who could connect it. So far, the device has been consistent and I haven't had any problems, but I almost wasn't able to use it. It might depend on the technician as to whether or not they'll connect you with service...Just a word of warning when buying used. It would have been nice to know that ahead of time.

Go with Netgear, it's approved for all those providers and easy to set up. Also neither Linksys or Cisco have anything to do with the modem, last 3 years manufactured by Belkon.

I don't think so, but I don't know absolutely. The device had to be entered into Comcast's registry as the modem device, but there was NO software (CD or otherwise) other than the Model Number, the serial number and the CM MAC number. I think the only thing proprietary about Comcast's "rental" modems for customers are the rental fees !

This modem was not intended for personal use. It was created for ISP use only, which is why some people may experience wireless incompatibility.If you purchase this modem to use as a customer owned modem on Time Warner Cable's service, it is very unlikely that WiFi will work, especially if you live in Kansas, Missouri, Wisconsin, Ohio, Kentucky, Tennessee, North Carolina, or South Carolina.In short, internet should function fine, but I would not purchase this expecting wireless service on Time Warner's network.

ONLY if this specific model is listed on Comcast's Approved Modem List. From what I have read, they have changed their hardware and support networks to specifically exclude "non-approved" modems. Their tech support people may pass you around but their hands are tied.

Yes, I have the TG862G and I run XFinity phone, wired and wireless internet. I don't pay rent anymore for modem and router. TV requires a separate digital cable box supplied by Comcast. Some configuration may be required, which Comcast Support will not help you with. I was able to resolve my iphone5 connectivity issues by going to online forums. Everything is working fine now.

I can't say for sure. I checked Cox's site, and they list only a handful of devices, and DON'T list this particular one (Linksys DPC 3008-C) I bought, as an approved replacement (although, that doesn't mean it won't work!). Many cable (ISP) providers want you to either rent or purchase your equipment from them, so rarely do they include models that they DON'T sell themselves. My apologies for not having a more definitive answer, but I have Comcast....an entirely different animal altogether. As much as I hate to say it, you may have to call their tech services dept., wait on hold for an hour or two, before you can actually get an accurate answer. I can't say for sure.

I have been using this modem with Comcast without issue. I just had to call them and give them the unit's mac address and wait on the line for a few minutes while granted access. After that I returned their modem and reduced my month bill by $5.

YES!!! Called Cox customer support and gave them serial number and details of unit. They were very helpful and not concerned that this is a 3rd party router (not their leased unit). Router does drop signal to wireless laptop every once in a while but easy to reconnect. I use wireless to connect two televisions (Netflix via Roku) and a couple of laptops and iPads. Signal is strong and haven't seen any problems with buffering on Netflix/Amazon streaming video.

Yeah it worked perfectly with TWC for me. You just have to call them and they will get it registered. It took a bit because of some problems but it works so much better than my last modem.

FWIW - Cox just sold me ($89) the SB6182 as their premier cable modem, even though their web-site clearly lists the SB6183 as new to Cox as of 6/27/14.....I have it installed and it works quite well. Though I will not be shy about getting the SB6183 if it pops up in their store window next week.

I use all of my own gear. I will not allow Comcast to put anything other than a cable TV box in my house. Comcast's device can be used by Comcast to provide public WiFi. You have to opt out if you don't want the device in your house to provide this service.

I can't say specifically about TWC, but i have it hooked up to a Surfboard6141 (comcast) with no issues.

I've had this modem for a long time and I have Comcast/Xfinity. However, I just looked at the approved device list on the Comcast website (http://mydeviceinfo.comcast.net/) and the SB5120 is no longer listed.

I use it with Comcast and have no issues, I can't speak to its compatibility with a wireless modem.

I've been using this Cable Modem with Cox Communications in San Diego since 11/29/2013 without any problems. Cox will wipe and replace the firmware within a few hours of connecting your modem to their network, their EULA states that they can do whatever they want to your equipment if it connects to their network and they are NOT responsible if something goes wrong.

I've had no issues with it. The tech when he installed my service tried to upsell me a newer modem saying this one was too slow. I constantly get 8 Mbps down and 5 up. And yes I have Comcast.

I got this for Comcast, found out later they won't let it on their system. I'd contact them and see if they allow it on their system.

I recently purchased this. Prior to doing so, I spoke with Time Warner Cable about its compatibility and they confirmed this was a compatible modem/router combo. All TWC networks operate at half duplex. The specs for this modem are listed at full duplex. As such, the purported 343Mbps is correct, but TWC networks will not be capable of that speed, regardless of service level.
