Motorola Mb8600 Docsis 3

The xfiniity compatible modem was super easy to set-up following the quick start guide included in the box. Word of advice for comcast / xfinity subscribers — when stepping through the set-up wizard, selecting the option to text an activation code is a joke — the code is only good for 15 minutes but i didn’t receive the text until 30 minutes had passed; just stick with your xfinity account name for the activation and provisioning. Xfinity upgraded to docsis 3. 1, and, while my own 6 year old trusty motorola surfboard sb6580 was working fine, xfinity found every reason to pester me about an upgrade and how much i’m missing not having a 3. I prefer to own my own modem, so, after perusing compatible modems for my region on xfinity’s approved device page, i narrowed my choices to the arris surfboard sb8200, netgear cm1000, and, this, the motorola mb8600. All three are comparable at 1001 mbps, 32 down x 8 up docsis channels, and docsis 3. All the cool kids love the arris — especially after they ditched the very problematic intel puma chipset and went with the broadcom’s offering — and for very good reasons, it has great hardware specs. Sporting 3gb of ram, 128mb /16 of nand flash memory it’s a tasty treat. And, were it not a horrific white box that clashes with everything in my apartment, i’d happily have purchased it. Vanity, thy name be monkey rat, i know. I’ve never had a lot of love for netgear, and, i found its hardware lacking — 128 mb of flash memory and 256 mb of ram. Ultimately not a huge game changer, with current theoretical home speeds at 1gb, but one would expect something a tad more, well, more from a name like netgear. While its feature rich — which, is saying something for a cable modem — i really saw no reason to down this path.

I recently upgraded my cox internet from the premier (150mb) to the ultimate (300mb) option. The ultimate internet can have speeds around 300mb down and 30mb up. With the upgrade, cox incorrectly sent me a docsis 3. 0 modem with a $10 monthly rental fee. With it i only got speeds up to 170mb down. Then i checked on amazon and there was a $10 off special on this motorola docsis 3. I purchased and received it in a couple of days. After i received it, i called cox to switch the modem (gave them the model number and mac address). After that i ran a speedtest and i got 343mb down and 32mb up.

Connected pc directly to modem and did the activation online. Super fast activated on comcast in under 5 min. After i activated the modem i connected my router and away i went. Internet now is more snappy. I moved from a zoom 5341h(4×4 modem)im on the blast tier and am seeing 230 meg down x 13 meg uploadsignals on my older modem were at +1 power on 4 downstream channels with an snr of 37upstream power stayed the same. As you can see with attached picture my snr greatly improved with this modem.

Received the motorola docsis 3. 1 cable modem on-time from amazon. Up and running within 15 minutes, no call to comcast. Motorola ultra fast docsis 3. 1 cable modem, model mb8600, plus 32×8 docsis 3. 0, certified by comcast xfinity paper instructions were in the box and also online. No firmware available for prior update. I had previously confirmed that this device is acceptable to comcast. Before buying any network device, always check that your isp supports the device you plan to buy. Unacceptable for us to rate an item poorly if its is not compatible with your stuff.

Instruction manual is terrible but motorola support is too notch. To use with comcast / xfinity:1) plug in modem, attach coax, and connect port 1 to a laptop with ethernet cord2) 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 laptop4) 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 power5) after plugging in modem it will reboot and then your wifi should now work. Tips: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 reuter2) 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 power3) 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.
