Pros: -Specs far above what I need and what I expect to need/want for many years to come
-Simple setup
-Default color = Black
-Runs warm, but shell is ventilated well enough (unless you put it in an enclosed space)
-2-year warranty, which is double the warranty period of the more expensive, competing product
-Helps you avoid paying lease fees
-Good history with TP-Link products, in general

Cons: Minor con: Status LEDs are actually brighter from the side as they are from the front

Other Thoughts: My review is from the angle of a power user in a 2-level home with a robust network with 15+ active wired nodes and 8+ wireless devices. I have had a D-Link DIR-868L Router & Motorola/ARRIS SURFboard SB6141 Cable modem in place since I switched to Xfinity/Comcast 50Mbps service in early 2014. It has been an extremely reliable setup and I had a bit of trepidation changing anything. We are all fairly heavy Internet utilizers, coupled with the fact that I work at home and have a home server/website utilized by a few hundred people a week, as part of the support function of my job. That usage grew from a few people each week, so upload speeds and reliability became far more important over the course of the last 2 years. As you may already know, this TP-Link TC-7610 costs about 35% less that the SB3141, which could mean either the Motorola is overpriced or it could mean that the Motorola is a better quality device – Only time will tell…
The switchover from the SB3141 to the TC-7610 was far simpler than I had anticipated. I had figured it would have to be done via phone, but was surprised to find that I could simply connect the coax cable to the new modem and then connect my laptop to the modem via the Ethernet connection. Note: I was logged into my Xfinity account with modem self-configuration start page open on my laptop before I began. Once the modem had powered up and made the connection to Xfinity, I simply stepped through the process and after a modem reboot, all was working perfectly. Internet test speeds are pretty much identical to the SB3141 and overall functionality seems to be identical. For wireless centralization, I have the modem & router on a shelf in the hallway above our washer & dryer. It also means that I look at it regularly as I walk by. Not being particularly fond of the mismatch of the white SB3141 and black router, I really like the fact that the TC-7610 matches the router. Of course, that doesn’t play into the rating of the device, more just to my OCD ;) As mentioned in the cons section, the front Status LEDs are actually brighter from the side (because of the vent holes) than they are from the front and since I have mine situated so that the side is facing the hall, it provides a nightlight effect. However, the overall brightness is still more subdued than the SB3141 status lights.
I give this device 5 out of 5 eggs without reservation. It is a great overall value, with the same specs and double the warranty of the competing product, yet costs 30-35% less.

Pros: Received in 2 days with free Shoprunner Shipping. Called Time Warner to up the speed on my plan from 50Mbps to 100Mbps, and give them the MAC address to activate the modem on my account. In less that 15 minutes I was up and running, with download speeds of 118Mbps, and upload speeds of 11Mbps. Whats not to like?

Cons: Only problem I had was reading the MAC address on the bottom of the modem so I could activate it. Plenty of space for a larger label for those of us with age-challenged vision.

Pros: Plug and go.

Cons: None.

Other Thoughts: I'm not sure people should be down-rating a product because it "isn't supported by x cable company". You need to go to your cable company's website and find the list of supported modems. They will have one somewhere on their site. Then you pick something from the list. You can't just buy anything and expect it to work (in a perfect world, sure, but...).

This cable modem is on Comcast's list (as of 2015) and it works fine. I followed the simple instructions that came with the modem and had no issues. Within 5 minutes or so it was up and running and I haven't touched it since. That was over 6 months ago.

I don't have any trouble streaming Youtube HD or Netflix. My MMOs work fine.

Here's comcast's list of approved modems.

http://mydeviceinfo.xfinity.com/

There are cable modems that support even higher tier speeds, but if you are not subscribing to the extreme tiers there's no reason to pay extra for something you're not using. Just buy what you need.

Pros: Very easy to set up. Comcast customer service tech had no problem activating my system in just minutes

Cons: I didn't buy this 2 years ago when I went to cable.

Pros: Like most cable modems, it's just plug in the coax cable and the ethernet cable, plug in the power and you're good to go. It was cheaper than most other modems.

Cons: It takes a little longer to connect than the RCA/Thompson DCM425 that was provided by Time Warner Cable, but it was a matter of seconds and not minutes. I usually don't have to restart my modem so it's not a deal breaker for me

Other Thoughts: This modem is on the approved list for customer purchased modems at Time Warner Cable. They have also made it easy to provision your own modem, you don't have to call anyone, it's done through the web browser. TWC modem rental fees went up to $10 in January 2016, so this modem will pay for itself in half a year, then you start saving money. Also, I received marginally better speeds from this modem than the TWC provided one, but it's really the cost savings that makes this modem worth it for me.

Pros: Price is slightly better but that was not the reason for the purchase, speed tests very high using Comcast and I'm promised 50Mbits but seem to be testing at 70. Up speed maxes at 6Mbits and this is the same as my previous, much older Doc 2 modem.Some reviews on other sites say it runs hot, mine does not. Buy it,

Cons: None so far

Pros: Good stats, aesthetically great, small size, doesn't feel cheap

Cons: CableOne doesn't support this model. I'm sure it would work fine, but they won't connect it just because it's not on the "Supported Model" list.

Pros: When it comes to having a Cable Internet provider, most service providers will lease you their own equipment for use with their service. Some providers will charge you equipment fees. There are limitations to what those devices are capable of in terms of bandwidth and connectivity. This modem will allow you to relinquish the OEM device and remove the monthly equipment fees being charged to your account (be sure to send your provider the old equipment upon activation). Upon receiving this modem, the first step was to power on the modem and establish connectivity via the Coax Cable installed by the ISP. My initial set up from there consisted of directly plugging the modem into a computer via Ethernet. A simple CAT5e/6e cross over cable works perfectly. Certain providers allow modem activation through one of their account webpages. Other carriers will automatically redirect the modem to an activation page once connectivity is established and a web browser is launched (if this is the case, be sure any manual DHCP and DNS settings are removed). If neither option works, calling the ISP and registering the device via MAC address works perfectly. With this modem, the process took a little less than 10 minutes to be completed and connectivity was established. The ISP will dial into the modem and remotely power cycle and activate it. Be advised, some carriers will remotely flash the firmware on the modem with one of their own, assuming they fully support the modem on their infrastructure. Luckily, my carrier did not do so, thus preserving any custom functionality I used from the modem.

Cons: The device gets warm under constant use, but that's expected of any modem. Keep it ventilated if possible.

Other Thoughts: I am currently subscribed to the Charter Spectrum network. My bandwidth throughput averages 60Mb/4Mb, with ping times averaging between 8ms and 22ms. I do tend to see the connection peak higher than the 60Mb I'm subscribed to. I've also noticed that I have 8 Downstream Channels and 4 Upstream, with a maximum connectivity of 200 IPs Incoming/Outgoing. For any users that torrent or use some form of file sharing, I suggest you cap your seeding ratios to a limited number of users and throttling your bandwidth accordingly.
Also on the coaxial connection, try to minimize the number of splitters and devices being tethered onto the hardline before it reaches the tap. I requested my ISP to install a separate line from the outdoor residential tap to the modem, which alleviated a lot of my bottlenecks and service interruptions due to flooding.
Also, as a side note, if you subscribe to VOIP through your ISP, you will have to keep the phone box/modem that runs the service. Speak with your ISP as to how that connectivity will remain established, if necessary.

Pros: -Docsis 3.0 provides 8 times faster speeds than 2.0
-IPv6 standard
-Gigabit ethernet port
-Saving money by owning rather than renting

Cons: -Takes a little longer than the average modem to power reset
-Produces a little more heat than the average modem
-Slightly larger than some modems
-Download speeds limited to 340-350mbps (might need to replace in 2020?)
-Docsis 3.1 will come out soon

Other Thoughts: I had to get rid of Comcast triple play and get rid of phone and cable to use this, but it was well worth it. This modem works just as well if not better than the old TC8305C I was renting from Comcast, and over the course of a few months pays for itself. Definitely a great investment, especially if you're near the start of a contract.

I needed to do a hard reset before this modem started collecting updates from Comcast. Once the online light was green, it started working with my router a few seconds later and through Wi-Fi I was able to activate with Comcast. Easier than I expected.

Pros: It has a maximum data rate of 343 Mbps downstream with eight channels and 143 upstream with four channels. This DOCSIS 3.0 modem is also backwards compatible with DOCSIS 1.0, 1.1 and 2.0 standards. It supports IPv4/IPv6 dual stack, PPT, L2TP and IPsec VPN pass-through, and support for IGMP v1/v2/v3 multicast.

Cons: Keep in mind this is a budget modem. Other wise none. See other.

Other Thoughts: There are faster modems, about twice as fast available. But for me and most other people a faster modem speed will not make a difference. Just because the speedometer goes to 200 doesn't mean it can goo 200. If you cable provider only provides 50Mbps a fast modem will not make your up and down speeds faster.
