How do I use a Netgear CM400 cable modem with my Time Capsule router?

I switched out my TWC modem for one I bought. I called and activated a CM400 Netgear modem with time Warner cable. They said it is activated and responding. My time capsule is on a green solid light but i can't connect to the Internet! Why??

Your previous setup may have been a modem router and the TC is connected in the wrong mode.. it should be dhcp and nat with a pure cable modem.. is it?
You also might need to put the TC into the correct mode.. then power off the modem for about 15min.. (try 5min first).. power up the modem.. wait 5min and then power up the TC .. it should grab the public IP and route that to the network.. reboot all the clients so they get fresh connection and see if that works.
If not give us a few screenshots from the airport utility of how the TC is setup.

  • How do I use a Windows PC and Mac with the Time Capsule?

    Hey all,
    Here's the situation that I face. I have a Windows Desktop PC without a wirecard, and a MBA..
    My Time Capsule is connected to my ADSL modem, and my Windows PC is hooked up to the TC via LAN.
    I was able to set up the TC from the MBA easily and got it up and running flawlessly.
    However, when I started Airport Utility on the windows machine, it was unable to detect the TC, though it is plugged it physically to it via LAN.
    Would appreciate any advice.
    Thanks!

    Make sure the windows 7 network is set to home not work or public.
    You might also need to turn off the firewall.
    Airport utility can usually detect the TC without trouble but the default names are probably wrong for SMB network..
    Name of TC (and wireless if later you use it) should be short no spaces, pure alphanumeric.. especially no apostrophe which apple seem to put in by default.
    In the disk sharing page, make sure guest account is turned on and has read and write permissions.
    Make sure workgroup is set correctly.
    In the windows machine make sure bonjour is installed and working.
    In windows explorer type \\ipaddressofTC or \\TCname.
    If no go, press and hold the reset button on the TC and redo the setup from the windows computer.

  • How can I set up a guest access point with a Time Capsule and an Airport Extreme? I am using a Telus router with the Time Capsule used as a wireless access point (bridge mode). I don't want the guest access point to have access to my network.

    How can I set up a guest access point with a Time Capsule and an Airport Extreme? I am using a Telus router with the Time Capsule used as a wireless access point (bridge mode). I don't want the guest access point to have access to my network.

    The Guest Network function of the Time Capsule and AirPort Extreme cannot be enabled when the device is in Bridge Mode. Unfortunately, with another router...the Telus...upstream on your network, Bridge Mode is indicated as the correct setting for all other routers on the network.
    If you can replace the Telus gateway with a simple modem (that performs no routing functions), you should be able to configure either the Time Capsule or the AirPort Extreme....whichever is connected to the modem....to provide a Guest Network.

  • I am using an Macbook pro in conjunction with a Time Capsule. I back up all my aperture librarys on it, but how can i view these images that are stored on the capsule please ??

    If you want to see what is in a file that is backed up by time machine then you have to restore the entire file. Having said that I have had good experience with Time Machine and individual files... if the file is there then all of it's components are almost for sure there. A way to get around this in Aperture would be to use referenced images. The images then still exist as individual files and can be backed up and restored individually. You would have to do so on a file by file basis though and your album information would still only be saved within the Aperture library.

    No, you connect to your Time Capsule wirelessly to "Extend" the network..

  • How can I use an USB contacted SC-Card at the time capsule via my iPad!

    I have a camera memory card with an USB-connector. In my holidays I want to store the pictures from the card to the time capsule.
    I want to use the ipad for remote access to the timecapsule. The pictures from the card should be stored at the TC.
    Is this possible with the time capsule and remote acces via iPad? Which app is required?

    Here is what I would look into.
    Use iCloud and photo stream to upload pictures taken with the iPad.
    Find a remote log in utility, or web based app to then remote to your computer.
    Download the files from photo stream to your time capsule.
    As far as recommending a remote log in utility. I have not experience in that area and would need to do research my self.

  • How do i set up a wireless access point with ny time capsule

    I am using a new Airport Extreme and want to utilize my older TC to create a wireless access point or maybe an aditional router using the same newtwork.  What are the steps to set this up?
    Thanks

    You will first need to perform a Factory Default Reset on the Time Capsule.
    Resetting an AirPort Base Station or Time Capsule FAQ
    Then, temporarily locate it in close proximity (same room or nearby) to the AirPort Extreme.
    Open Macintosh HD > Applications > Utilities > AirPort Utility
    Click the tab in the upper left hand corner of the AirPort Utility window that reads Other AirPort Base Stations (1), then click the Time Capsule
    AirPort Utility will take a moment or two to analyze your network, then announce that the TC will be configured to extend your wireless network.
    Enter a name for the TC (you can use the same device name that you used before if you wish) and click Next.
    AirPort Utility will take a another minute or two to configure the TC and then tell you that the setup is complete. Click Done
    At this point, power down the TC and move it to a location that is approximately half the distance from the AirPort Extreme and the area that needs more wireless coverage.....to give the TC a good strong signal to "extend"
    Power up the TC and wait for the green light and then you are all set.

  • Can i use the computer while backing up with the time capsule for the first time? the

    I would like to install the time capsule. Since it will take some hours to complete the task, do you know if, at the same time, I can work on the computer?
    Thank you.

    Yes, work away.. it might slow down the backup but not significantly.. make sure you do that first backup by ethernet connection though.. it should take less than over night.. so really not that big a deal.

  • How do I use my 8300 as a modem for my laptop

    Hi all,
    I'm new to this forum. This is my first post...
    I'm trying to set up my 8300 smartphone to be used as a tethered modem for my laptop to be able to get the full internet content anywhere with in cell coverage.
    Question 1: 
    I got instructions from the 'BlackBerry HELP' icon on the phone (my question was: how do i use my device as a modem) which seemed very complete. The modem is dial-up and when I try to connect I get Error 718 (basically a timeout error). 
    Can anyone help? 
    Question 2:
    Since this uses dial-up, would I be using my cell phone minutes?
    Thank you, Lar 

    hello,
    first thing is to look on the forum if people have already solved your issue. In this case, the tethering subject is quite frequent. You will certainly find your answer among these discussions :

  • As a Verizon FIOS client, can we just use Ethernet cable to connect to time capsule, or do we need their router to connect to the time capsule?

    As a Verizon FIOS client, can we just use Ethernet cable to connect to time capsule or do we need the Verizon router to connect to time capsule?

    The Time Capsule is indeed a wireless router with simultaneous dual band capability...and a hard drive for backup purposes. You can use that to your advantage if you configure the Time Capsule as I suggested in Bridge Mode.
    The Time Capsule will provide a 802.11n 5 GHz band and a 802.11n/g/b compatible 2.4 GHz band to allow virtually any device to connect to the network.
    I suppose that you could also use the "g" wireless network provided by the Verizon router as a "guest" network or something similar if you really do need another wireless network.
    It might be possible to configure the Time Capsule as the main router on the network....that's a question for Verizon. But even if you might be able to do this, I'm sure it is not supported by Verizon, so you would be on your own in the event of any Internet connection difficulties on your service.
    And, since the Time Capsule does not have a built in modem....you would still need to add a separate modem to the installation anyway.
    That's why my suggestion is to use the Verizon device as the "modem" and let the Time Capsule provide the dual band wireless network and of course, handle the Time Machine backups.

  • I have a new Macbook pro and can't recall the password I used with my Time capsule - How can I (ideally) retrieve or possibly change the time capsule password?

    I have a new Macbook pro and can't recall the password I used with my Time capsule - How can I (ideally) retrieve or possibly change the time capsule password?

    Remember security on a TC is an illusion.
    Simply press the reset button for 1-2 sec.. you must not do too long .. it will then hard reset.. but soft reset will revert all passwords to default for 5min. ie TC password is now public.
    Remember this the next time because anybody at all can change your passwords.
    Once into the TC you can then open the view passwords if you wanted any weaker security. Click and open the TC.. and click on edit.. then go to the top menu..
    Voila .. all your passwords in plain sight to any Tom Dick and Fred.
