Style: DOCSIS 3.0 Modem Only
I purchased this modem in 2018 and here we are in 2024, it is finally starting to see some diminished performance. Overall it is still functioning but with noticeable degradation in download speed with some minor connection issues here and there. I work from home so will replace as I can't afford any connectivity issues. Prior to this I have not had any issues with the modem. It has performed well with speeds consistent with those purchased from my provider Spectrum. The original install was simple and I've never needed technical support as the modem has never had issues. I have a great Wifi router, and I would recommend this modem for anyone who is looking for a modem-only setup for direct connect or to pair with Wifi at 400GB speeds or lower. The price was great and longevity/performance exceeded my expectations for the price point.

Style: DOCSIS 3.0 Modem Only
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.

Style: DOCSIS 3.0 Modem Only
I was tired of renting my modems from the cable companies. So based on previous experience I decided to purchase this modem. I have previously worked for a major cable company in their high speed data division. Essentially going to customers and troubleshooting their internet connection problems (not the telephone tech support but a real person who could root cause a connection issue and resolve it for you). So I figure I know a little something about cable modems. Arris used to be a company with somewhat mediocre modems. Along with the Thomson RCA brand. There's been a lot of merging and aquisitions with the modems and Motorola used to make the best modems with the "shark fin series". Well peeps this is essentially a Motorola modem and delivers the performance that I expected for one of their modems. I have had zero issues since installing this modem. Installation was simple with the usual connections and a quick call to the cable company with the MAC address, Two minutes later surfing away like a champ. We use Ooma for our telephone service along with 3 Roku's on the go and two Android Media boxes and this keeps up with the stream seamlessly. Of course being Docsis compliant you can always go and remove the bandwidth cap if you want to (don't condone this but it's possible) to increase your bandwidth if you wanted to by running a script. In a couple of months this modem will have paid for itself comparing to rental costs from the cable company. 100% reliable, emits a good consistent upstream signal which is what is needed to make your internet happy. The cable company sends you a downstream signal which is your incoming data. The cable company is responsible for the signal strength heading your way. Your modem does have some tolerance in terms of how low the signal can go before connection fails but largely if it gets that low then the cable company should be fixing it for you anyway. The upstream is where it really counts and think of it like this, your modem transmits a signal to the cable company (they refer to it as upstream or return). The cable company and their servers are most likely miles away from where you live and your little modem sends out this little signal and between you and your cable company location it passes through a series of amplifiers that increase your signal strength in order to reach the hubs. As long as you have the signal strength to make it to them you're good to go. This modem never saw any fluctuation in the db readings on the upstream so I know that if there is an upstream issue then it is most likely owned by CC and not my modem. I have seen sporadic readings on other modems but nothing yet with this unassuming little box. The lights can be a little bright so if they bother you that much just put some tape over them. I bought this modem for it's performance not its aesthetics, I don't care what lights are on as long as I have a signal and everybody is doing what they want on the internet be it streaming, news or whatever. Good value a great buy and stellar performance.
