Time Capsule connectivity issues with cable modem

I have Comcast internet service (coming through a Linksys CM100 modem, no router) plugged directly to a 2TB dual-band TimeCapsule. In the past this has been working, and the TimeCapsule has been providing internet access to three Macs, as well as backing them up. I also have an AirPort Extreme base station (not the dual-band one but not the 2003-era UFO-shaped one either) that has been connected to the TimeCapsule over house ethernet to provide wireless through the rest of the house. Last night my connection kept dropping out. I could connect to one wifi network and it would not work, then I would connect to the other and it would work for a while before stopping. I have disconnected everything and then replugged only the cable modem and my TimeCapsule. When ethernet is plugged directly into my iMac from the modem, I get an internet connection without issue. When I plug it into the TimeCapsule, it reports an internet connectivity error. It says it gets no IP address, and no DHCP setting that I provide it with alleviates this message.
I'd be gratful for any suggestions on how to fix this issue. I don't really want to wipe the TimeCapsule completely, as it contains our backups to last July.

When ethernet is plugged directly into my iMac from the modem, I get an internet connection without issue. When I plug it into the TimeCapsule, it reports an internet connectivity error.
Because cable modems associate and "remember" the device with which they have established a connection, they need a complete reset whenever you change the device that is immediately connected to them.
Push the reset button, If present, on your modem
Power off the modem
Pull the battery if it is easily accessible
Power off everything else on the network, order if not important
Wait at least 15 minutes
Make sure that the Ethernet cable from the modem is connected to the WAN port (circle of dots icon) on the Time Capsule
Power up the modem and let it run 2-3 minutes by itself
Power up the Time Capsule the same way
Power up each of your other devices about a minute apart
Check for proper operation the network.

  • Time Capsule not working with cable modem

    I have a WebStar modem using Cox cable internet. When I plug the ethernet cable into my Macbook directly out of the modem, I have internet. When I plug the Ethernet cable into my Time Capsule - I have no internet and the lights on the modem do not flash. The modem is not recognizing the TC or the TC is not recognizing the modem. Any solutions??? Please help.....

    It's the former.
    Power everything down, including the modem. While it's powered down connect the TC's WAN port to the modem. After a few moments of peaceful contemplation, power up the modem and then the TC.
    You should then be able to configure the TC with Airport Utility, if you haven't already done so. If you can't, and you need to reach the outside world again, resist the temptation to connect your computer directly to the cable modem. Connect a computer to the TC's LAN port instead.
    Here's the applicable explanation from Apple:
    *You've done everything right, but still can't connect to the Internet. Why?*
    It's because the modem locked onto your iMac, and it will ignore anything else you plug into it until it's been reset. If you were to plug the iMac back into the modem, it would still connect to the Internet.
    Fortunately, resetting a broadband modem is usually very easy -- just unplug its power supply, wait a moment, and plug it back in. After its indicator lights have gone through their startup routine, you should do the same to the AirPort base station.
    Odds are that you can connect to the Internet now.

    I have a Airport network at home with a Time capsule connected via ethernet cable to modem. Also the network is extended wirelessley with an Airport Extreme. I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme.  Can my network operate properly to extend the network with both a wireless and wired extend functionallity?

    I now wish to add a second Airport extreme but am considering a hard wire connection with 100 ft of cat 6 cable from the Time capsule to the second Airport extreme.
    Excellent plan.
    Can my network operate properly to extend the network with both a wireless and wired extend functionallity?
    Yes, but don't get confused about the second AirPort Extreme, as it would not be configured to "extend" a wireless network.....it would be configured to "create a wireless network" using the same wireless network name, security settings and password as the Time Capsule network. Configure the second Extreme in Bridge Mode.
    This Apple support document will show you how to hookup and configure the second AirPort Extreme:

  • Problem with Time Capsule connection to Verizon Fios modem.

    I recently switched to Verizon Fios service. I connected my Time Capsule into the Verizon modem and since then the Time Capsule light has blinked Amber.
    Is there anything unique to the Verizon Fios Modem that is causing the Time Capsule to blink Amber?
    Thanks

    run airport utility, it should tell you why the light is blinking amber. In all likelihood, it is because you have double NAT. turn off NAT in your time capsule. you may also want to access your verizon router using 192.168.1.1 and turn off the wireless radio. no need to have two wireless networks pumping out signals. while in the router settings, you can lower the firewall too, assuming you have adequately protected the TC.

  • Setting up Time Capsule as router with DSL Modem as bridge

    Hi All,
    I want to work this out in my head before I start disconnecting wires. So let me run down what the situation and plan is. If you see a potential issue, I would appreciate the feedback.
    What I have:
    Verizon DSL. The DSL modem is also doing duty as the router. For a lot of reasons I don't need to get into here, I no longer want the DSL modem to be the router. I have gotten instructions on how to setup the DSL modem to serve ONLY as a bridge. In that configuration, you simply connect the DSL modem to the phone line as usual, then connect your router to one of the ethernet ports. My time capsule has been serving only as a wireless access and backup drive until now. So here is what I plan to do:
    1) Connect via ethernet cable, the WAN port on the TC to the ethernet port on the DSL modem.
    2) Using the manual setup screen on the TC, select the "Internet" tab.
    3) Set "Connect Using" to "Ethernet"
    4) Set "Connection Sharing" to "Share a public address"
    5) TCP/IP set to "Using DHCP"
    At this point, everything should work. At least I think it should. Am I missing something?
    Any suggestions appreciated.
    Thanks,
    R

    I haven't worked with the Verizon gateways, but configuring the device as a simple bridge might require that the Time Capsule be setup to furnish the PPPoE service. You won't know until you try.
    If you are not able to "Connect Using - Ethernet", then that would be an indication that you would need to instead "Connect Using - PPPoE". In this case, you'll need to enter your user name and password that you have established with the service provider in the Time Capsule setup configuration. Be sure to leave the Service Name area completely blank if you setup using PPPoE.
    If you are able to "Connect Using - Ethernet" and you configure the Time Capsule to "Share a public IP address", you may see a warning during setup that this is producing what is known as a Double NAT on your network. This is normally not too serious, unless you are trying to setup online gaming, which requires a different type of NAT setting.

  • Time Capsule not working with new modem

    I have been using my TC with our motorola modem for 2.5 years. On Friday last week, the modem crapped the bed and AT&T sent us a new modem, a netgear. The modem is working fine; when I connect the ethernet cable directly to my laptop the internet work perfectly, however when I try to get the wireless network going through my TC, there is no connection. All the lights on the modem work fine and every time I try to work with the TC, it says that it is working fine as well. It seems like something is not communicating between the modem and the TC.
    I've tried restarting both machines numerous times, I've checked and rechecked the WEP password, the IP addresses are fine, and I'm still lost
    The modem works. Time Capsule Works. I don't get it!

    The new netgear is probably a modem router whereas the old Motorola was pure modem.. not sure but possible.
    Reset the TC and set it to bridge modem.. plug into the netgear modem router.. and it should work fine.
    If the new netgear is in fact a pure modem.. you need to turn it off and put the TC in place.. wait up to 15min for the ISP to renew the lease on the MAC address then turn on the cable modem.. wait then turn on the TC. But this is not necessary if it is a router.
    What is the model number of the netgear so I can check this.. ?

  • CAN not run a time capsule connected on a zyxel modem from solcon (glasfiber)

    i have bough a mac book and a time capsule
    this time capsule i connected with "wire" to the zyxel wireless modem 
    then on my mac book i make the installation of the time capsule and it works
    BUT BUT only for 10 - 15 min and then
    No more connection / no more wifi

    Set the TC into bridge mode.. just google it .. there are heaps of posts.
    If you still have issues ask.. but ML and TC are not exactly robust at networking.

  • Better to create or extend my existing network? (Time Capsule, Express, AppleTV with wireless modem internet)

    We have Optus ADSL broadband (Australia) running wireless via a 'Sagemcom F@ST 3864 Optus' modem. We have an Airport Time Capsule (for backup) and an Airport Express (for music connection) and Apple TV.
    I currently have the Time Capsule (Express & TV) set up as their own network, sharing the internet from the Optus wireless network. Is creating a new network like this the best scenario? Or is it better to extend the existing Optus wireless network? Besides extension for range/reception, does either option have particular benefits over the other?
    Other than internet, we just stream music/movies from laptops & phones to speakers/TV, so the thinking behind creating a new network rather than extending, was based on the assumption that the Time Capsule may be better at data transfer than the modem?
    Any thoughts would be great!

    Is creating a new network like this the best scenario? Or is it better to extend the existing Optus wireless network? Besides extension for range/reception, does either option have particular benefits over the other?
    I would say it is about 50-50.. 6 of one .. half a dozen of the other.
    Any scenario you dream up has a set of good points and bad points.
    So some factors.
    1. I presume you have the TC plugged by ethernet into the Sagem modem.. bridged and creating its own network.. using two different network names keeps the local connection load contained which is good thing.
    Wireless is fundamentally poor. It has limits on being only able to handle a single client at a time.. so time slicing between all the clients. plus it is half duplex.. which is simply it can either transmit or receive not both.
    In comparison, Ethernet via modern switches.. can have multiple computers talking to each other at once and can both tx and rx, ie full duplex. So using extend wireless is very bad. It means wireless is much slower as each packet is double handled.
    Using multiple APs connected back by ethernet to a main router is definitely the right way to go. They can be in roaming or setup with completely different names.. that is almost irrelevant. It is easier though to manage when you do the naming and setup so you specifically allocate load.
    For example.. if the TC is doing backups from TM on the computers and you start having streaming issues with the Apple TV, split the load, by naming the 2.4ghz and 5ghz differently in the TC.. and force backups to 5ghz and streaming to 2.4ghz (or visa versa depending on range issues etc.).
    2. Network wise different AP should all live happily together in one happy family. The reality is that more equipment leads to more issues. I have been hitting a few issues lately with wireless routers exactly in your setup being unavailable to the network, if a computer happens to be connected to the wrong router.
    For example a computer connected to the Sagem, whether by wireless or ethernet, may have issues backing up to the TC. It shouldn't but it does. I am seeing Mavericks in particular giving strife this way.
    Someone recently posted a very helpful article on why this is happening.
    https://discussions.apple.com/thread/5863043?tstart=0
    For most people in a home network you do not want the hassle of running a server. But you can see that sometimes things start getting complicated.
    Best principle is hope for the best.. set it up as per what you have done.. if it bombs or is unstable.. work back through the issues.. there are some alternative configurations which are more complicated.. eg running the TC with static IP, that seems to alleviate some of the bugs.
    3. What works is best. Whatever the theory.. try a few setups.. what you setup that works well for you is the best even if the theory says no.. that is bad.
    eg One post a person used roaming network with all AP's fixed to the same channel, so the idevices would roam properly. This is wrong.. but works.. normal roaming network laptops seem to be able to roam well but idevices do not. Pick what works.

  • Time Capsule download issues with Windows 7

    Hello together
    My problem is as follows: upload to Time Capsule with two PCs running on Windows 7 (both 32 and 64 bit) and a Mac Book Pro is working without any problems occuring. TC and the two PCs are in the same workgroup and PCs are connected via WIFI in private mode.
    Download from TC to Mac Book Pro works without problems. But in contrast to that, when downloading with the two Windows7-based PCs the connecting is breaking off all the time and the message "Network error" will be displayed. In order to get a new connection to TC the power plug must be unplugged and replugged again. Do you have any advice what to do? Thanks very much in advance.

    Are you using SMB compatible names for the TC and wireless.. short, no spaces.. pure alphanumeric.. If not do so?
    I also recommend using fixed channels and maybe fixed mode. Lock up as much as possible as the PC does not deal as well as the Mac with the auto band, channel and mode switches.
    I am not sure what you mean by this..
    PCs are connected via WIFI in private mode.
    Please explain a bit more.
    Windows wireless drivers are often terrible.. many people have fixed issues by using a more recent driver direct from the wireless card manufacturer.. this is important.. not windows default driver,, not computer manufacturer supplied one.. eg intel card then get latest intel driver from intel.
    Are you running bonjour for windows on the PC's??
    Try using static IP address which also might help.. windows did have issues with dhcp in the past.

  • Airport Express and Time Capsule connection issues

    I have the following setup:
    - Airport Express set up as 'create a wifi network' with the exact same name and password as my main network from my BT router
    - Time Capsule setup to 'join existing network' which is the same name - obvioulsy! - as the other two.
    Everything worked OK until fairly recently. My MBP which usually is connected to the AE n/w accessed the TC via Time Machine OK, and my iMac backed up via TM to the TC OK as well.  Now, however, the TC (which is situated in range of both the AE and the main router) seems to connect sometimes to the (weaker) AE and sometimes to the (almost adjacent) main router.
    If it connects to the main router network, my iMac backups are OK, but if it connects to the AE network, then TM just fails with the usual 'backup disk cannot be found' even though it is clearly visible in Finder.
    Is there anyway of locking the TC into a particular network?

    OK, thanks for the information.
    Temporarily, disconnect the Ethernet cable from the AirPort Extreme to the Time Capsule's WAN port.
    Close AirPort Utility 6.1 on the Mac if it is open
    Start over by holding in the reset button on the back of the Time Capsule for 9-10 seconds, then allow 60 seconds for it to restart to a slow, blinking amber light
    Connect the Ethernet cable from the AirPort Extreme to the WAN port on the Time Capsule
    Click the AirPort icon at the top of the Mac's screen and wait a minute for the heading of New Apple Base Station to appear. Under that,  click on the Time Capsule.
    AirPort Utility will open automatically and take a minute to analyze the connection. After a minute, it will display a message that the network will be configured to "Extend".
    Enter a name for the Time Capsule and click Next
    AirPort Utility will take another minute to configure everything.  When you see the message of Setup Complete, click Done.
    You should now be able to connect to the Time Capsule wireless signal.

  • Can Time Capsule connect without Ethernet Cable?

    I currently have RoadRunner service to get Internet with my Mac, connecting my Ethernet cable to my Time Capsule. I want to replace RR with a Clear Network mobile hotspot. Is it possible? Both it and the TC are WiFi devices.

  • MacBook Pro and Time Capsule connection issue

    I have an issue where all the devices in my house can connect and work with my Time Capsule, except for my MacBook Pro. Everything has worked in the past(including my MBP), but last weekend my Time Capsule died, I went to an Apple store and got a refurb unit.
    After setting up the new unit, every device can attach and use it, except for my MBP. It appears to attach, but says that I don't have an internet connection. When I look at the attached clients on the Time Capsule, it shows all the devices by name, except mine is shown by MAC address.
    I have the wifi settings set the same as the other computers, etc., which do work. I can take my MBP to other places that have wifi, and it works just fine. It also doesn't work if I plug it into one of the LAN connections(Ethernet) on the Time Capsule. The other computers will work on wifi or the direct connection.
    After taking my computer to another place and using their wifi, mine worked when I brought it back home. This lasted for a few days, then it just stopped again this morning.
    I have restarted, shutdown, etc., the Time Capsule and my MBP many, many times.
    Time Capsule 512MB original unit, firmware(7.6)
    MacBook Pro 17", 9 months, 10.7.2
    Other devices: two iMacs, 3 iPhones, 2 iPads 2's, and an Apple TV.
    Anyone else having similar issues, any suggestions?
    Thanks in advance.

  • Time Capsule connection issues

    I connected my time capsule to a new internet at my college. The internet works, and the green light is solid. My computer and iPhone 5 say however, "No Airport base stations have been found. Airport Utility will continue searching." I have backed up this same computer, but in August 2012 when I lived somewhere else. Any suggestions?

    You haven't given us enough info.
    When you plug into your college system you must double NAT.. because the college will only give you one private IP address. The TC must be on a different IP address range. If the computer still cannot find the TC
    1. do a full factory reset and start over.
    2. Ensure IPv6 is set to link local only on the computer.
    3. Use all short names on the TC. no spaces and pure alphanumeric. Not the names the airport utility will suggest.
    4. Use WPA2 Personal security with a password of 10-20 characters pure alphanumeric.
    5. Manually mount the TC in the computer using Finder. Go, Connect to Server.
    Type in AFP://TCname.local or AFP://10.0.1.1 (Where TCname is the new short name.. local is correct default domain or the actual IP address.. 10.0.1.1. is default.)
    The computer will attempt to discover the network resource. When the password is requested store it in the keychain.
    6. Reset TM in the computer.
    A4 here. http://pondini.org/TM/Troubleshooting.html
    7. If the iphone still doesn't work set fixed channels for 2.4ghz and try 11, 6, 1 in that order. Maybe 8 as well if your college is saturated with people running their own wireless AP. I would go further and set the 5ghz to a different name to 2.4ghz and attempt to use that. There are more channels available and less interference issues.
    The college probably has rules against using your own AP for precisely this reason.

  • Time Capsule connection issues - only VPN use will connect

    After hours of troubleshooting with Comcast and Apple trying to establish internet connection, I accidentally discovered that I could get on when connected to company's VPN. Why would this happen? I don't have VPN on my Mac and don't want to set it up on my iPhone. I need to get on the internet without it. Apple has been helpful on the phone, but they are just as stumped as I am -- we've tried everything! Help!
    I'm running 10.5.2 on Mac, and use XP on my PC's. The cable modem is an Arris through Comcast. I never had problems with my old wireless router (Netgear).

    Wired or wireless didn't matter, it was baffling.
    I did get it resolved, however. Evidently Comcast's DNS address wasn't working properly. The Apple rep was able to provide a public DNS address (not affiliated with Comcast) that did the trick. The VPN thing was what tipped him off.
    Works fine from the Mac, but my PC's give me constant warnings since they are set up with all of my company's security settings. I can live with it though! Just happy to finally get some work done!

  • Time Capsule Connectivity Problem with Airport Utility and Mavericks

    I have a Time Capsule from 2011 which worked perfectly with my IMac and Airport Utility 5.6.1 but since the upgrade to Mavericks, I cannot get it to work with Airport Utility. Any help much appreciated. Thanks.

    When you say.....
    I cannot get it to work with AirPort Utility....
    What does not work?  Can you open up AirPort Utility and  take us through the steps? What happens after each step?
