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.

    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?

  • Re: Motorola SURFboard SB6121 DOCSIS 3.0 Cable Modem

    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.

    How do I get a previous version of Firefox. Firefox 17 does not work with online banking edit

    P.S. Firefox 17.0.1 is supposed to be released Friday ([https://wiki.mozilla.org/Firefox/Planning/2012-11-28#Current_Releases ref.]) so you should start checking for updates tomorrow by going to the Firefox Help menu and clicking on "About Firefox". See [[Update Firefox to the latest version]] for more information.

  • How do I get back to 3.6? 4 says it won't work with my configuration, even though I'm running 10.5.8

    I downloaded Firefox 4 & it overwrote 3.6. F is saying that it will not open with my configuration even though I'm running 10.5.8. How do I find & download 3.6? I'm totally screwed, since I can't seem to import my bookmarks, setting, etc, into Safari or any other browser.

    Unfortunately, Firefox 4 supports only Mac OS X 10.5 and above on Intel hardware. The system that you are currently using is no longer supported by Firefox (details can be found [http://www.mozilla.com/en-US/firefox/system-requirements.html here)].
    <BR><BR>You can revert back to previous version of Firefox by following these steps:
    # Open the Applications folder.
    # Drag the Firefox application to the Trash.
    # Download and install Firefox 3.6 from [http://www.mozilla.com/en-US/firefox/all-older.html here].

  • How do you get [(webcrawler) searchengine]in the search bar? Or will it work with foxfire?

    I can appreciate that the search bar already has google, yahoo and bing search in it's search bar. But is there any way to put webcrawler.com in the search bar as a search engine. I tried to figure it out but with no luck. Thanks for reading my question, and any help at all would be appreciated.

    In addition to what John said, Final Cut Pro X is a digital download from the Mac App Store. To see if your MacBook meets the requirements, see > http://www.apple.com/finalcutpro/specs/ Anyway, the App Store will give you an error if your MacBook isn't compatible.
    Since the Final Cut Pro X launch, it's only available at the Mac App Store, so you can't get it in a DVD. Instead, there's an advantage: you can install it as many times as you want in all your Macs for free

  • How do I get back to FireFox 5. The 7 version will not work with the college's MIS - which does not support version 7, which was downloaded automatically.

    The Angel management system used for classes does not support version 7. That's huge.

    Old versions of firefox 4,5 & 6 are no longer supported or considered secure. You put your system and your personal data at risk if you use them. Further more if you download from third party sites you face other potential risks or inconveniences.
    The recommended official solution is to use Firefox 3.6 which is still supported, and will be 3.6.23, which will upgrade soon to 3.6.24
    Another alternative is to use the current secure firefox for all day to day work, and use a separate firefox portable for the problem school site. With luck a firefox portable version will be available with firefox 3.6.23 which is currently the supported version. http://portableapps.com/apps/internet/firefox_portable/localization#legacy36

  • 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!

  • How do I get my ipod to play a playlist from reverse order? (Start with recently added song instead of first added)

    How do I get my ipod to play a playlist from reverse order? (Start with recently added song instead of first added)
    So I'm adding new songs to a very old playlist? Is there anyway that when I add them, they automatically go to top of playlist? How about getting one song to the top of a playlist.  That drag to arrange function is very annoying because it is slow and the playlist does not scroll up very well on a PC.

    Make a new playlist by pressing the little plus button at the very lower left corner of iTunes. An new playlist will appear in the Source pane called "untitled playlist". While the name is highlighted, you can change it to whatever you want. Drag all of the tracks from all the albums that comprise a single book to that playlist. Sync that playlist to your iPod.

  • How can I get the iBook app on my Mac to backup ePubs I created with Pages on my iPad? Only seems to want to work with purchased from the ibook store.

    How can I get the iBook app on my Mac to backup ePubs I created with Pages on my iPad? Only seems to want to work with purchased books from the ibook store. The problem is, once I create a document in Pages and turn it into an ePub to be opened in iBooks, I delete the document in Pages, because I don't need two copies taking up space on my iPad. Before Maverick, iTunes would backup everything in my iBook app on my iPad. If something ever happened to my iPad, all of my created ePubs would be lost and I would be screwed. I suppose I could keep everything on Pages and go to iCloud and download my documents to my Mac, but that is a lot of steps. I may have to do that if there is no other way, but I am hoping someone will have the answer for me. Pretty disappointed in iBooks app for Mac at this point.

    iBooks only syncs purchased books. Others must be synced in iTunes.

    How do I get a new icloud account for my phone when it was setup with my wifes account?

    Go to Settings>iCloud and sign out. Any synced data, such as calendars and contacts, will be removed.
    To get a new ID: go to http://appleid.apple.com and create a new ID - you will need a different non-Apple email address from any ID you already have.
    Then go back to Settings>iCloud and sign in there, enabling any data types you want to sync in the list there. You will be asked to create a new @icloud.com address when enabling Mail.
