2 out of 5 eggsFast modem but bad connectivity

Pros: Fast, 5 Ghz speed, DOCSIS 3.0

Cons: You have to bridge it in order to work, the concept of having both modem and router is brilliant but it gives poor router like features, in fact lacks those.

5 out of 5 eggsTop of the line

Pros: Great Price going through, Very easy to install, all information that the ISP would need to add the modem to your account is clearly named on the device as well as the product comes with a card that has the information, Web based UI is a bit overwhelming, but Motorola offers good help guides for what each options is.

Cons: Where the help guides inside the Web UI is good, there should definitely be more information available for some of the rarely used features. help is a bit vague on some of the features.

Other Thoughts: All in all, this product is a great addition if you are in need of a DOCSIS 3.0 all-in-one cable modem, router, wireless unit.

5 out of 5 eggsBang for the Buck and Long-term Savings

Pros: -No Modem Lease Fee indefintely through ISP,
-Modem and Router in Single Unit reduces wire clutter and saves space.
-Gigabit ethernet supports virtually any consumer level bandwidth speeds currently available. Also allows for fast transfering of files between different devices within the same Home Network.
-Dual Band N-router has good range and signal strength, capable of supporting multiple wireless devices at quick speeds.
-Supports upcoming next-gen technology such as DOCSIS 3.0 and IPv6.
-Router Software/Firmware has extensive features, including parental controls.
-WPA2-PSK (and other options) to help ensure "bandwidth thieves" aren't robbing you blind.

Cons: -802.11 n is "old" technology, does not have newer AC level wireless bandwidth.
-Does not come with adjustable external antennae.

Other Thoughts: Running 50 Mbps service from ISP, seeing speeds over 7 megabytes/sec. through my wired ethernet desktop PC. Supplies plenty of wireless bandwidth and connections stay strong throughout the apartment, even after travelling 60 feet through multiple walls, and servicing up to 3 wireless devices simultaneously (Laptop while gaming, iPad, Android Smartphone). We have two people playing MMO's (one wired, one wireless) at the same time with no speed or connectivity issues.

Good bang for the buck and pays for itself (by not having to pay modem lease fees) far sooner than when it will need to be replaced for newer tech. Would Recommend to Friends and Family.

3 out of 5 eggsUpdate to my recent review

Pros: All in wireless router and cable modem, small footprint.

Cons: Ever since the recent update older devices in 2.4Ghz randomly lose internet access. Resetting the adapter resolves the problem, but it will randomly happen again. I tried many settings and advice from forums with people having similar issues, but the problem continued. I ended up replacing it with the enormous sized 6782-AC(compared to the 6580). Range is better on that unit especially in 5Ghz, but the 2.4Ghz problem still exists, but with better 5Ghz range, I bought a 5Ghz adapter and things fly.

This 6580 is dual band, but they do not run at the same time.

Other Thoughts: I'd recommend the White (and large) 6782-AC over this one because it range is better in both 2.4Ghz and 5Ghz and they run concurrently, the unit seems to run cooler and power supply is built in (no power brick)

1 out of 5 eggs

Pros: Only need one device

Cons: So slow, only getting 9Mbps while plugged in. On the on the SB6121 I get 95Mbps. Don't know how they can advertise the speed when it is not there.

5 out of 5 eggsGreat!

Pros: I have owned this Motorola/ARRIS modem for a few months now and have not had any problems with it until today (see other thoughts) It's been reliable and quick, works well with my wired and wireless devices plus my WD Cloud

Cons: Either Comcast or ARRIS pushed a firmware update recently that messed up Wi-Fi. (see other thoughts)

Other Thoughts: When I got this modem, the set up page ( was all Motorola, It was simple, basic looking with the features an average user would need. Just within the past couple weeks, either Comcast, or ARRIS (who now operates the Moto SURFboard line) pushed a new firmware which changed everything. The setup page is all ARRIS now, but the new firmware also messed up the Wi-Fi where it would cut in and out. I ended up just factory resetting the modem then setting it back up to how it was and it seems the problems have been solved. The new ARRIS set up page is much better looking than Moto's, and with pretty much the same options, but much easier to navigate and use.
