Great SOHO Gateway
By Timothy Walker
When assessing this type of equipment, one ought to distinguish amongst the device itself and other components that may affect it is performance. Blaming the manufacturer for issues likely caused by one’s ISP is akin to saying, “I can’t get past third gear because of all this construction on the highway… I’ll never buy a Jaguar again!”

Not for the timid or uninformed
By R.B.
The SBG6580 may genuinely be a niece all-in-one device if you have the forbearance and know-how to get it setup right.
First off, there is a feature called ‘IP Flood Detection’ that needs to be disabled. (It is located beneath the Firewall page) By default, it is turned ON. When ON, this feature in the end causes everything to slow to a crawl. Turn it OFF (uncheck box) and you will never go slow again. This is surely a failing on Motorola’s share to default a poor-functioning feature ON in the introductory place.
I would agree that Motorola’s interface is clunky in general. It is finelooking powerful too and progressed users will be competent to do most of what they want with it.
My carrier is Comcast and I take delight in real-word DL speeds of up to 4MBps (32mbps). Admittedly, with a lot of of my apps, I’m actually around 3MBps, which is a great deal fast for me. I have (2) hardwired PCs, (1) hardwired printer, (1) wireless laptop, (1) wireless printer, and (3) other hardwired gadgets on my network.
I do experience a random ‘reset’ of the modem on occasion. I have yet to track down what is causing it. I can’t blame the hardware (yet) but it occurs with such irregularity (sometimes not for 5 days or more)
It isn’t a perfective modem/gateway, but it is capable, if a touch user unfriendly.

Great Amazon Experience – Wonderful Motorola Product
By Techie
Watch Video Here: http://www.amazon.com/review/R39QUHRRDZ4OWW Sorry for the Dyslexia – This review is on the Motorola SBG 6580 SURFboard eXtreme Wireless Cable Gateway – for the duration of my video I used an imcorrect model number 
BIG PLUS to this unit: You do not have to buy a seperate WIRELESS N ROUTER which saves with regards to $100 or so further and added cost. Some have said they purchased the lesser Motorola unit and then purchased an extra Wireless N router. This seems like an unneccessary expense to me.
Things to know:
This modem will ONLY work for CABLE-delivered Internet such as Comcast Xfinity ™ and a lot of other ISP’s using CABLE Internet signals. It will NOT work on AT&T UVerse network (because UVerse uses a hyped-up DSL technology)
1. Unbox unit
2. Connect AC Power Adapter to wall (recommend plugging into UPS power supply)- plug the other end into the back of this router.
3. Connect COAX cable from ISP wall plate to your modem. This is the same hexagonal cable connector type as applied to connect to CABLE TV.
4. Grab the included cat 5e ETHERNET CABLE (looks similar to a telephone cable) and plug one end into your laptop or PC and one end into one of the 4 ethernet jacks on the back of the unit.
5. If you don’t have an ETHERNET jack on your laptop or PC you’ll be going wireless – run the included INSTALLATION CD and follow the directions.
6. Open your webrowser (Internet Explorer, Firefox, Chrome, etc) and type in the modem address 192.168.100.1 then enter your username– admin and password– motorola and hit login button.
7. You’ll be looking at a web-based SETUP SCREEN with TABS from left to right.
8. Click on FIREWALL tab, locate the IP FLOOD DETECTION checkbox and UNTICK IT (remove the checkmark) then click on the APPLY button.
9. Pick up phone and call your ISP. From the box that shipped with your device – read the ISP the model number (SBG 6580) and the MAC ID number (the MAC ID varies from one unit to another and is printed on the bottom of your modem itself as well as the shipping box.
10. Be sure your isp offers DOCSIS 3.0 SIGNAL or you will not reap the max speed from this device.
About the accompanying video:
about 4 minutes of hands-on demo with this device including real world speed test from the Internet. Remember to go to FIREWALL settings and un-tick IP FLOOD DETECTION – if you don’t you will not get max performance. Otherwise simple to set up and blazingly fast. Note: Hard-wired (ethernet) is always going to be much more quickly than wireless. This proved true on my network, 30.77 mbps download speed realized (hard wired) vs 10 mbps Wireless. Overall I’m exceedingly happy – no negatives at all. A Must-Have piece of equipment. Important: Your ISP needs to provide good quality signal and use DOCSIS 3.0 engineering science to achieve the higher speeds (30 and above) cited in this review. Don’t blame this instrumentation if you have a bad ISP connection you won’t get the performance. My ISP is Comcast. Fiber optic is a lot more quickly than UVERSE IMHO.
