MB8600 is a DOCSIS 3.1 Cable Modem certified by Comcast XFINITY, Comcast Business, and Cox Communications. Owning your own modem typically saves $132 per year in cable modem rental charges. MB8600 supports ultra fast DOCSIS 3.1, the only cable modem standard that can deliver Internet speeds of 1Gbps or higher, up to many gigabits per second. Actual speeds depend on your cable modem service and the speed of your Ethernet LAN ports. MB8600 also has 32x8 support for the fastest possible speeds using the DOCSIS 3.0 standard. Even if you don’t have DOCSIS 3.1 service now, you can benefit from the 32x8 DOCSIS 3.0 capability that’s also built into this cable modem. MB8600 provides high-speed Internet for a computer, router, HDTV, game station, or streaming media device. To give simultaneous Internet access to many devices, plug in any router you like. MB8600 features low latency, for the fast response needed for many interactive games. It includes 1 open Ethernet GigE LAN port. There are 3 additional Ethernet GigE LAN ports masked behind a label. Current firmware supports bonding on 2 Ethernet ports, which is essential for delivering speeds over 1Gbps. Top actual speed is just under 1Gbps without bonding, just under 2Gbps with 2 bonded ports. In order to have port bonding increase your modem’s speed to just under 2Gbps or more, your router needs to support port bonding. It includes DOCSIS 3.1 Active Queue Management (AQM) which speeds page loads, gaming, and video conferencing. DOCSIS 3.1, 3.0, 2.0, and 1.1 support and Cable Labs certification ensure compatibility with services nationwide. Setup is fast and easy with our Quick Start guide. Our experienced USA-based support specialists are ready to help if you need them. With Motorola extras including advanced surge and lightning protection, and a 2-year warranty, MB8600 is a superb choice for customers who want the ultimate in cable modem performance. MB8600 does not include a WiFi Router or VoIP telephone adapter.

There was a problem filtering reviews right now. Please try again later.
The lights on the modem stay on (blue for DOCSIS 3.1), and the link light is blinking, but there is no connection.
Can't even access the modem's admin interface (192.168.100.1). The router is working fine when this happens (I can access other computers on the network).
Turning the modem off/on fixes the problem (it's able establish a connection pretty quickly after resetting, 2 minutes or so).
The event log in the admin interface doesn't have anything logged.
Power and SNR all seem to be within appropriate ranges.
Cons: Instructions say to go to xfinity.com/internetsetup but it doesn't load, you actually want /activate. Before realizing this, I tried to activate remotely from my xfinity account and it said activated, but it wasn't.
Overall opinion: There is no competition right now.
To use with Comcast / Xfinity:
1) plug in modem, attach coax, and connect port 1 to a laptop with Ethernet cord
2) go to xfinity setup webpage on your laptop and enter account credentials to activate modem (web page address is in instruction manual)
3) modem will reset and then you should have wired web connectivity with your laptop
4) unplug modem power, disconnect laptop and connect terminal 1 of modem with Ethernet cable to your router with router powered on, and then plug in modem power
5) after plugging in modem it will reboot and then your wifi should now work.
1) you may need to factory reset your router to get it to connect with this modem. I had to reset my apple time capsule reuter
2) this is a bridge modem, so you must power it down before connecting a router. Plug in router to modem and give router power, and then plug in modem power
3) only one port can be used. The rest are for bridging signals once that functionality is available from ISP. You can only use one of the four Ethernet ports on the rear
Update: Just did another SpeedTest. Achieved almost 950 mbps!!! I added a screen shot of those results.
TL;DR see pros and cons below
Had issues with my old Motorola Arris Surfboard modem constantly cutting out every 2-3 days forcing a hard reset. Since I've installed this new modem, I haven't had any outages. Great that Motorola is developing their own hardware now instead of in partnership like with the ARRIS Surfboard line in the past.
Product claims to be "plug-in-play" with Comcast XFINITY, but I still had to contact XFINITY customer support (over an hour via online Chat) in order to get it to register an internet connection where I could proceed to "activate" my new modem. So I'd say that's falsely advertised. I'm assuming Comcast does this on purpose so that they can up-sell you on your service when you contact them. The rep was trying during the entire activation process to get me to upgrade– I had to ask him if it was ready for me to activate after 45mins into the conversation when he said he "forgot" to tell me that it was ready. I call BS.
Other than the annoying BS with XFINITY and this falsely being advertised as plug-in-play with XFINITY, this product has been very reliable so far. Runs very cool and quiet. I know many other modems run very hot– but not this one. Was registering about 27x4 channels with XFINITY when I checked last via the modem's settings. This can support up to 32x4 (if I'm not mistaken).
-DOCSIS 3.1 and 3.0
-Reliable, has not cut out yet like past Motorola ARRIS modems have for me.
-Pretty simple setup (see cons for more details).
-The future of modems, great investment at a better price than the Netgear and ARRIS branded 3.1 modems.
-Comes with power cable, ethernet cable, velcro tie for cables, and a wrench to tighten the coax cable.
-One time price, versus the monthly fee of renting one from your ISP
-Standalone modem and not router/modem combo making it more reliable longterm.
-AQM for lower latency, have yet to really notice this since I use all my devices over WIFI.
-Supports bonded (two ethernet cables) connection to ISP if you are lucky enough to actually have Gigabit internet service. One LAN connection only supports up to 960 Mbps or so speeds, so bonded is a plus.
-4 LAN ports if you want a direct connection (e.g. if your router doesn't support bonded ethernet– most don't– then you can directly connect to your modem with 4 available ports).
-Just that they advertise this to work really easily with XFINITY. At least that was my impression. I still had to contact XFINITY to get this modem set up. Was about an hour total online chat with them. Normally it should register with your ISP and prompt you with a "Activate your service" screen in your browser from the ISP, but was not the case for me.
