Review: rubbish - leave it ALONE more TROUBLE than its worth problem seller 1/10 Review: Pros: - Great speeds - Stable - Easy to setup (see note below) Cons: - Runs warm - Bright LED lights I bought this to replace an aging DOCSIS 2.0 modem I had been renting from Time Warner Cable (and had, over the years, paid enough in rental fees by many modems - gulp). It works great with the TWC service and based on standards and prior experience, I see no reason it wouldn't work with all major providers. As others have noted, you get a minor "speed boost" over older modem - this is not due to an increase in sheer maximum speed, since that is set by the cable company, but rather due to the ability of this modem to bond up to 16 channels maintaining the maximum speed more stably (instead of the speed bouncing up and down). The only thing that troubles me about this device is the fact that it does get fair warm to the touch - so make sure it's in a well ventilated area. The blue LEDs in the front panel are also very bright - and even if you wanted to cover them up, you can't effectively block the light as it comes through the main body (sides and back) of the device which cannot be covered due to the need for ventilation. This isn't a problem for me since I keep it in a "wiring cabinet" with plenty of ventilation and a door to block the light, but I can see it being an issue for some. Note on setup - I attempted and failed to be able to use TWC's "auto-setup" so I called their support line. They told me there was an "outage" in my area so while they would enter the data, I wouldn't be able to use the modem until the outage was repaired. This was curious to me, since my internet worked perfectly with the old modem not 30 seconds before. So, with the guy on the phone (without him telling me to), I unhooked this new modem and re-plugged in the old one...suddenly he tells me the outages is fixed and he's able to provision the new modem. Strangely, as soon as he enters the new modem, the "outage" reappears. So again, I switch modems without him telling me to (now having the new one plugged in) and boom, outage gone and new modem works like a charm. Long and short of it? If TWC doesn't see the modem they have in their system plugged in and powered on, there's an "outage" and they can't install a new modem. So if you can, plug in both your existing modem and this new one at the same time (maybe in different rooms) and they'll be able to set the new one up with no issues - in fact, auto-provisioning may work. ## Features - Item category: modem - Trademark: GENERIC - Manufacturer: Generic ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01ERK1JLM | | Best Sellers Rank | 378,902 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 175 in Modems | | Box Contents | Cable Modem, Power Cord, Quick Start Guide, ethernet cables, power cord, quick start guide | | Brand Name | ARRIS | | Colour | white | | Compatible Devices | Personal Computer | | Customer Reviews | 4.3 4.3 out of 5 stars (8,584) | | Data Transfer Rate | 400 Megabits Per Second | | EU Spare Part Availability Duration | 2 Years | | Global Trade Identification Number | 00612572209929 | | Internet Service Provider | xfinity | | Item Dimensions L x W x H | 12.7L x 5.4W x 13.3H centimetres | | Item Type Name | Cable Modem | | Item Weight | 1 Pounds | | Manufacturer | CommScope | | Maximum Downstream Data Transfer Rate | 686 Megabits Per Second | | Maximum Upstream Data Transfer Rate | 131 Megabits Per Second | | Modem Type | Cable | | Network Connectivity Technology | Ethernet, Wi-Fi | | Number of Ethernet Ports | 1 | | Number of Ports | 1 | | UPC | 612572209929 | | Unit Count | 1.0 count | ## Product Details - **Brand:** ARRIS - **Compatible devices:** Personal Computer - **Connectivity technology:** Ethernet, Wi-Fi - **Internet service provider:** xfinity - **Product dimensions:** 12.7L x 5.4W x 13.3H centimetres ## Images ![ARRIS (SB6183-RB) Cable Modem - Fast DOCSIS 3.0 16x4 Gigabit Cable Modem, for Comcast Xfinity, Cox, Spectrum and More, 1Gbps Port, Maximum Internet Speed 400Mbps, 2 Year Warranty - - Image 1](https://m.media-amazon.com/images/I/51PbjvN726L.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐ rubbish *by A***B on 21 October 2023* leave it ALONE more TROUBLE than its worth problem seller 1/10 ### ⭐⭐⭐⭐⭐ Review *by B***T on 22 March 2015* Pros: - Great speeds - Stable - Easy to setup (see note below) Cons: - Runs warm - Bright LED lights I bought this to replace an aging DOCSIS 2.0 modem I had been renting from Time Warner Cable (and had, over the years, paid enough in rental fees by many modems - gulp).
