ARRIS / Motorola SurfBoard SB6141 DOCSIS 3.0 Cable Modem

I am planning on giving back my leased TWC Modem and buying this Motorola/Arris SB6141 DOCSIS 3.0 modem. Does anyone know if here are any issues w/this modem and Mac OS X 10.9.5? Any info would be great.

Is WMM enabled?
Does your PC have a Wireless-N adapter?

  • How do I get a Motorola SurfBoard SB6141 DOCSIS 3.0 Cable Modem to work with my AirPort?

    I just bought a Motorola SurfBoard SB6141 DOCSIS 3.0 Cable Modem to replace the one Comcast was renting to me. My configuration is as follows:
    Modem is wired via ethernet to the AirPort Time Capsule
    Time capsule is wired to an iMac, a PC, and an Xbox 360
    Time capsule is wireless broadcasting to connect various peripherals around the house (iPhones, consoles, printer, Macbook, etc)
    Anyway, while the modem works great plugged straight into the iMac, we completely lose our internet connection (wired and wireless) if I plug the AirPort Time capsule into it.
    Does anyone know if there is a conflict that I can disable on one of these devices? The airport utility was warning of a double NAT.

    Did you power off the SB6141 for 20min before you change over from iMac to the Time Capsule.. this is required. (Test at 5min if you want).
    Make sure the TC is set to dhcp on the internet tab.. and DHCP and NAT on the network tab.
    Power up the modem.. wait a couple of min for it to settle down then plug in the TC.
    No luck try longer times.. or ring comcast and ask them to reset the IP.
    If your TC is tall one or running 7.6.4 firmware.. another problem may arise where the 6141 does not connect properly.. there is a problem between this modem in particular and the apple routers.
    You can try using a crossover cable instead of ordinary patch cable or use a small 10/100 switch between them.. that will sometimes help.

    Had the same problem even after calling comcast, how do i turn off block sync mode?

    Block synch mode is not a function that is able to be toggled on and off by an end user. Nor would you want to. It means that the modem is synchronized / online with the Comcast system.

  • Airport Express not working with Motorola Surfboard Sb6141 and TWC

    My 2012 Airport Express was working fine with my Motorola Surfboard Sb6141 and TWC until about a week ago when the signal started dropping constantly. I hard wired the modem to my computer and everything worked fine. I took the Airport Express to the Genius Bar and it is working fine. I have followed the instructions posted throughout this board to reset the AE to factory settings, then turn everything off for 1/2 hour, turn on just the modem, the the AE 15 minutes later and the computer 15 minutes after that, but to no avail. When I try to set up the AE using Airport Utility, it allows me to assign a name and password, but then the light goes to solid amber and I get "An unexpected error occurred. Try again." Any ideas?

    I'm still struggling trying to get the SB6141 to stay connected with my Airport Extreme but it drops altogether every day or 2 but if you're looking for an alternative, I've heard the Netgear CMD31T works well with the airport.

  • Internet jamming up with new Motorola SURFboard SB6141 modem

    I recently purchased a Motorola SURFboard SB6141 and every hour or so our internet jams up (we have an iMac, iPads and iPhones), I reset the modem and it works great for another hour or two.  We have an Airport Express router.  Everything worked fabulously until we set up our new modem.
    I read on an older thread that the firewall in the SB6141 wasn't compatible with Apple products and folks had great success with turning off the firewall on their modem.
    Can anyone give me steps to turn on my modem's firewall?  Or, is there any other advice to be offered?
    Thanks so much!!!

    Hi - I just switched to Comcast and I bought my own Motorola SB6141. The tech left and it didnt actually work until we unplugged the modenm and restarted it. The TV worked, the VOIP owrked, but not the internet. When everything came back up it was working and we changed the name of the network and the LAN, and it worked for a few days and it was slow. Since I bought my modem at BB and its withing the return policy I'm going to return it. Based on the discussions I have read throughout this forum, it seems to be a total headache to try and get SB6141 to work with the setup I have. If you check the list of approved devices by Comcast, the SB6141 is on there, but ther are other devices that have gone through more thorough testing - http://mydeviceinfo.comcast.net . Most of the devices that have undergome all 3 tiers of testing will be the best bet. The downside is that you will have to call their tech support and get them to approve your device and get it set up. The comcast forum doesn't paint a pretty picture as well with this modem. Looks cool, though - it has that APPLE WHITE cleanliness!
    Good luck to us all!

  • Will my airport extreme 2nd generation work with docsis 3.0 cable modems?

    Will my airport extreme 2nd Gen work with docsis 3.0 cable modems?

    RRoger, everything is working fine.
    So, what is the actual problem here?  You are now wondering if the Vonage can handle the speed from the modem? Is that the "problem" after all this discussion?
    now I am wondering if my current setup will allow me to get docsis 3.0 speeds.
    What speed is your Internet provider delivering to you?
    The AirPort Express uses 100 Mbps Ethernet ports, so it will handle up to 100 Mbps. We have already told you that.
    Vonage likely does the same. The answer is almost certainly "yes" .......both the Vonage and AirPort will handle the speed from the modem.
    If you want to double check this, please provide the model number of the Vonage,  and we will try to look up the specifications for the device. If you have documentation there with specifications for the Vonage device, check to see if the Ethernet ports are listed as 10/100. This is standard with almost all devices, with some of them handling even higher speeds 10/100/1000.
    Chances are, your network will handle a lot more speed than your service provider is supplying to you. So, the "choke" point on your network may very well be your service provider and modem......not the Vonage and AirPort.

  • Networking: extend wireless network Apple Time Capsule to cisco DOCSIS 3.0 cable modem

    How should I connect a Time Capsule (4th gen) to a Cisco DOCSIS 3.0 that came with xfinity service to create a wireless extension to network... any  special settings???
    Should I use the Cisco or TC for the DHCP controller?

    You cannot wireless extend a network using TC.. Apple designed it to only work with other Apple products.. this is not that unusual.. but it is important .. you cannot do what you want.
    One network .. one router. Keep the cisco as the main router and plug in the TC by ethernet and bridge it.. that is router bridge not wireless bridge .. you will find the control in the NAT and DHCP section of Lion
    Or download the vastly superior older version of the utility here.

  • Best Cable Modem for Airport Extreme 802.11ac ?

    I own an Airport Extreme 802.11ac.  I am preparing to purchase a cable modem.  I have pretty well selected a - Cisco Model DPC3010 and was wondering if anyone had experience marrying the two? 
    NOTE:  I have heard that though the Motorola Surfboard version (ARRIS / Motorola SurfBoard SB6141 DOCSIS 3.0) has been tested with the AE, the modem still drops connections a lot with TWC.  Has anyone had similar experiences using that modem? 

    ISP:  I am working with TimeWarnerCable in Clarksburg WV area. 
    CISCO & TWC:  I have already confirmed that the Cicsco router is usable on their network - confirmed through TWC tech support and Amazon product reviews.  This is true despite the router not listed on TWC's external and internal approved lists. (The Tech escalated to confirm Amazon review statements that the device could be connected).
    CISCO & AE: I am just curious if someone else out there has experience using it with their AE - no matter who is their ISP. Any hiccups?  Any thing to watch for?   (Thanks in advance)
    Note:  the Motorola device IS on the TWC approved list, but there are too many reports of frequent dropped internet connections.

  • Can I use my airport express to establish wifi with Motorola SB6120 SURFboard DOCSIS cable modem?

    Can I use my airport express to establish wifi connection with a Motorola SN6120 DOCSIS 3.0 cable modem?

    Yes, the AEx goes into router mode.. plug in via ethernet to the modem port.. you then need to power cycle the cable modem.. it might need to be off for 20min or more before it will lose the previous connection and start afresh with the Express.

  • Having trouble "extending" Airport Express to DOCSIS Motorola Surfboard

    In 30 minutes of searching this forum, it is clear Bob Timmons is the man when it comes to Airport Expresses.
    I had ATT DSL connected to 3 airport expresses (A1264) for streaming music in smaller apartment.
    I'm now in a bigger rental home and want to extend the network.  After some tinkering, I can get the A1264 to "join my wireless" network but I can't get it to "extend."  When I choose those settings, I get the blinking amber light - and it will not work.
    I'm connecting to a Motorola Surfboard DOCSIS 3.0 cable modem.  Can anyone help?
    Thanks
    Ron

    If you are trying to extend the network wirelessly......Apple's extend a wireless network feature will only work with other Apple wireless routers. 
    To confirm, please see this excerpt from Apple's product literature on the AirPort Express:
    Extend an existing Wi‑Fi network’s range.
    If you already have a wireless network in your home and want to extend its range, AirPort Express can help. Just place it in range of your primary base station — an AirPort Extreme, AirPort Time Capsule, or another AirPort Express
    http://www.apple.com/airport-express/
    If you have a Motorola modem/router providing your wireless network, the AirPort Express will not be able to extend that signal.

  • Bridge an AirPort Express from an Extreme connected to a Motorola DOCSIS 3 cable/modem/gateway via an ethernet cable? Can I connect ethernet to the Express to setup/handshake/coordinate, and then unplug the ethernet cable from the Express?

    In other words, does the AirPort Extreme NEED to be the device connected to the coaxial cable, or can I connect that cable to the Motorola SBG6580 DOCSIS 3.0 cable modem/wireless gateway? (My Internet provider requires DOCSIS 3.0 for speeds above 12 megabits/sec.)
    Will the Airport Extreme "program" the Express via an ethernet cable, and than the cable can be removed?
    The "bridge" or "repeater needs to be quite a distance away from the physically connected cable modem/wireless gateway and the ethernet- connected AirPort Extreme, and we have wall-to-wall carpeting, and the walls and ceilings are off-limits (family politics), so a looooong ethernet cable is out of the question.
    Any help is GREATLY appreciated!
    Thanx!
    P.S. The 802.11 in my house (ground floor, about fifty feet away from the modem; in the living room about 35ft away *****! And Motorola touts this wireless gateway as having amazing coverage (360, I think they call it),but in fairness, this house is old and has a 5 hanset cordless landline and a microwave and a fan, etc., etc., etc......

  • No internet from grandecom cable modem

    Solved!
    Go to Solution.

    If the WRTs gets a public IP address 24.155.*.* from your ISP then the router configuration is correct. Check the Status page in the web interface.
    Do those computers use DHCP?
    It's probably best if you open a command prompt window on your computer and enter "ipconfig /all". Copy the full output into your response. That should show your current IP configuration on the computer.
    The gateway IP address in your LAN 192.168.1.* is 192.168.1.1.

  • Motorola - SURFboard DOCSIS 3.0 High-Speed Cable Modem - Silver

    can you use a Motorola - SURFboard DOCSIS 3.0 High-Speed Cable Modem - Silver and a router instead of the modem/router that they provide?

    I'm not sure if you're asking about DSL or FiOS service.
    DSL service requires a DSL modem, not a DOCSIS modem.
    FiOS does not use modems, just routers.  FiOS routers do have a MoCA (coax) port to talk to the ONT and set-top-boxes.  You can use non-Verizon routers with FiOS, but it requires an Ethernet connection from the ONT instead of MoCA.  If FiOS TV is used, a Verizon router must be in the mix.
    So, the short answer is there is no Verizon service that uses DOCSIS.  Cable-modems are not used with Verizon services.
    Good Luck.

  • Help - Motorola - SURFboard DOCSIS 3.0

    Good Morning, I tried searching but could not find an answer to my questions. I purchased the Motorola - SURFboard DOCSIS 3.0 recently and have had problems with my internet connection ever since. Almost everyday about 12-1 AM it shuts down and reboots. Will do this same things at other times during the day. Yesterday, I had flushed my DNS settings - first time ever. I find the page load times to take much longer than before. I switched out the cable company's provided modem (2005 technology) for my own (save $5 a month) - I am now regretting this change. Any ideas what might be going on? I don't want to return it - if I can repair it on my own. Thanks in advance - any help is appreciated. FH

    The only time when your modem/router would be involved as far as streaming goes would be how fast your connection is compared to how strong your wifi connection is.
    A wifi signal with one bar may not be able to transmit the signal at all angles that well everytime the signal bounces back or however that works. At least that's the only logical thing I would think about.
    As far as streaming being slow though, are you using silverlight or an adobe player of some kind? I have fixed so many machines where adobe player had hardware acceleration turned on which would destroy a persons streaming ability.
    Another option would be to try to reset the settings for your browser. If you can supply the browser I can gladly supply information on how to do this.

  • Motorola Surfboard 5101 Cable Modem

    I just wanted to post a message about my findings and my solution to the Mototrola SurfBoard 5101 Cable modem. I use comcast as my ISP. I was using an old COM21 modem. I was getting around 4300 KBPS on a broadband test from Speakeasy. Since Comcast was starting this PowerBoost, I needed a DOCSIS 1.1 compliant modem and the COM21 modem wasn't. I went to my localComcast office to switch it out since I was leasing one. They gave me a SurfBoard 5101. I already saw the postings and the articles on Macfixit.com. I tried the modem and was getting 2700 Kbps. I tried everything to get the speed better. Connecting my iMac directly to the modem. Tweaking TCP settings.
    I called Comcast and they said they never heard of the issue. I explained of all the postings I saw and the artiles also. She said she believed me but didn't know of the problem. I found one article talking about using other modems. The newer Surfboard 5120 modem said was better but had issues with Comcast's network and would disconnect. They said the linksys cable modem wasn't any better. The one they said was the best was the DLINK DCM-202. It was 49.95 on sale at Best Buy. I thought, what the **, I'll try it. If it didn't work I can return it. I got it home. Installed it. Provisioned it and ran the Speakeasy tests. I was blown away. I got a speed of 9049 Kbps. Just ran the test while typing this.
    So if anyone else having this issue, I would return the cable modem back to Comcast and ask for a non Motorola modem. That's the advice the Comcast rep told me. Or just buy the DLINK modem. I can now return the 5101 modem and stop leasing it and finally I get my full speed.
    Thanks!!!

    I did some more research into this and see what anyone out there thinks. The Dlink modem uses a TI chipset with a method of controlling ACKS called Turbodox. It does ACK filtering. I also have read the the newer Motorola Sufboard modem (5120) works fine with Macs. This modem also uses TurboDox.
    If you run a tweak test from DSLREPORTS.COM, it states to turn on selective ACKS. Selective ACKS is an option in OS X. Delayed ACKS are. I have tried the delayed ACKS on my iMac with the 5101 but didn't have any luck. I noticed also a person mentioned in the macfixit.com article said he thought the delayed acks setting helped his issue.
    I am wondering if the TurboDox is taking care of this "selective acks" setting at the modem level instead of the machine level. Since the Macs can't do this the modem does and the connection is much faster.
    I found a white paper on the TurboDox implementation and what it does with ACKS:
