Time Capsule - No DNS servers and Double NAT

I'm connecting an MBP running 10.5.6 to a Time Capsule which accesses Virgin Media broadband using a cable modem.
It has been working fine for 6 months, but I made some changes this morning to get my wireless camera onto the network, which broke the connection, and don't seem to be able to undo them.
The TC now flashes amber, and going into Airport Utility I get the following errors:
- No DNS Servers
- Double NAT
I've typed the DNS servers' IP addresses for my ISP into Airport Utility but it doesn't seem to recognise them. It also complains about a double NAT problem but I don't have another router assigning IP addresses.
I've also tried a hard reset on the TC, switched it and the modem off, waited 30 mins and then switched back on again - no luck.
Screenshots of all the settings on my TC from Airport Utility are here:

I'm not very knowledgeable about networking so any assistance appreciated.

Double NAT is an indication that you have two devices on the network both trying to perform routing duties. You only want one device doing this on a network. Solve the NAT issue and the DNS issue will go away as well.
What is the make and model number of the device that you call your "modem"?

I have a new comcast modem i have connected to Time Capsule with cable, TC in double NAT. As when I tried it in bridge mode I cannot use Sonos, the units will not connect to the wifi network? I thought Bridge mode would make the wifi signal better??

I have the TC connected to the comcast modem, with TC in Double NAT mode. I set up the sonos music players ok. But I read that to incresae the wifi signal the TC should be in Bridge mode. Then I cannot get any of the Sonos units to connect to the wifi network.
So two questions, does the Bridge mode give a better wifi signal then double NAT?
Why will sonos not connect to the network when in Bridge mode?

A PC can have more issues connecting than a Mac.
But it really should not matter.. so just try it in situ.. press and hold the reset.. once it starts up, it will return to default IP, 10.0.1.1 the PC should then be able to find it via the airport utility.
If not drag it over to the Mac and plug in there by ethernet.. or since it is a laptop, really should not be that difficult to drag the Laptop and plug it into the TC.
Important thing is to get access to the TC.
The Mac if it is running lion, then you MUST download and install 5.6 airport utility to do anything useful.

No DNS and Double NAT

Hello, I've recently encountered a very frustrating bug in my system that I could use some help troubleshooting. I've read several similar posts, some are resolved while others are not, however none of the resolutions have worked for my situation. Here it goes:
I have an old macbook pro, a new macbook air, a white macbook and 2 iPhone 4s's all connected to the internet via WiFi through an AirPort Extreme. The AE is connected to a cable modem which has internet service through Cablevision in NY. There is also an AT&T Microcell hooked up to the AE to boost my cell signal. All of this equipment has been working flawlessly together for a long time. Until recently. It could have started after an update, there have been several lately on all of the equipment including the firmware in the AE. Anyway, I'll be connected without any issues - all lights green and happy - when suddenly, the internet will drop off and the AirPort Utility will pop up and warn me that:
1) On the "internet" icon, it will say "disconnected"
2) On the AE icon, it says "No DNS server and Double NAT"
After a few minutes and nothing done on my part, the lights turn green, the internet reconnects and all is well again.
This happens frequently and is really beaching a nuisance. Due to the frequency of the disconnection, I can no longer download a large file, update, or anything. Streaming video is impossible.
So far, I have tried bridge mode and cycled the power in the order recommended to no avail. When I do that, the AE turns green, but the internet says "not connected". I have also read that there might be too many IP addresses which is not sitting well with my ISP, so I disconnected everything including unplugging the Microcell. Lastly, there are no other wireless phones or devises in the house. All to no avail.
I should also mention that this began occurring on my Time Capsule, which I replaced with the AE in an attempt to fix this issue.
Any help would be greatly appreciated.
Joe

Sounds very similar to what I've been trouble shooting for 2 months now, only I have DSL from AT&T and I don't see the Double NAT warning. My last post on the problem is here.
My only emergency solution for getting by day to day on the internet is to unplug the AE and connect one Mac directly to the DSL modem. There's no shared connection or WiFi. I looked at hosting WiFi from the Mac, but the only security available with that is WEP which isn't considered secure. Even with this set up, I think (seat of the pants) that there are quality of service problems.
I've replaced the Airport Extreme with 2 different new units and the DSL modem with a new unit to no avail. The Genius Bar and Apple phone support couldn't solve this, nor have 2 calls to AT&T support and one visit from an AT&T repairman.
I would like to know how to better test or quantify the poor quality of connection that seems to be the problem.

How can I override the DNS Servers and Domain Name used by my Airport Time Capsule?

The defaults picked up from my ISP's DHCP are to use the ISP's DNS servers and ISP's domain. I do not want this.
With my prior router I set the DNS servers to Google's Public DNS (8.8.8.8 and 8.8.4.4) and my domain to either "bannister.us" (which I own) or "bannister.home". I do not want simple names resolving to some ISP default. (Yes, I know exactly what this does.)
In the Apple AIrport Utility (version 6.3.2) the fields for DNS and Domain do not allow editing. (Why??)
Is there some way to override this?

Unfortunately not one that will work with the latest version TC.
The way around it is to use a different router.. It can be a very simple router.. I usually recommend units like the TP-Link WDR3600 as they take good third party firmware like gargoyle, openwrt, dd-wrt.. ie they have real controls and beyond that a proper Linux firmware with command line interface.
You can then change the TC over to static IP. It will not be the router.. but it will effectively become the local dhcp server.
I have adsl so I cannot reproduce your system.. I have a bridged modem.. a router.. AC66U.. and a TC.. but the TC is not in bridge.. it is in static IP mode.
Let me demonstrate.
By setting a range on the main router from 1-199 (leave a space.. ) so set the TC to 192.168.2.201 and then you can set DNS and domain as you like. Set the dhcp range (leave a space) you could use 203-253.. then I use the main router as 254.
It is brilliant.. all computers behind the TC receive the IP from the TC with whatever IP and dns (and domain although I haven't changed it).. Effectively the TC works as its own dhcp device.. but is merely a secondary dhcp server to the main unit.
(This gives me netflix which is why I do it.. from well outside the US).
It may be of use.
Why leave a space.. well it helps it to work.. I have not tested it but another person reported issues and found leaving a space .. ie last ip in the router.. 199, static ip 201.. first dhcp 203 (i used 205 to help me keep count!!). worked.. I have not tried to reproduce the problem.. so I reproduce the solution.. it might be like sheep jumping over the fence.. even if the fence was removed the sheep keep jumping over at the same place. Just say bahhh and do likewise.

My macbook pro is connected to internet via my time capsule but my iPad and iPhone won't. it shows wifi connection to the time capsule but when i go on to the internet on the iPad or iPhone, it comes up with network error. can anyone help?

my macbook pro is connected to internet via my time capsule but my iPad and iPhone won't. it shows wifi connection to the time capsule but when i go on to the internet on the iPad or iPhone, it comes up with network error. can anyone help?

This can be caused by a number of issues.
Was everything working and then suddenly stopped??
Or is this a new clean setup and has never worked.
Do you have a cable modem which is not a router and the TC setup in bridge? That will cause it. The TC must be in router mode, ie dhcp and nat.
Check the IP the MBP gets including dns and gateway..
Then check the ipad/iphone.. post what IP dns and gateway (router in applespeak) they get.

My home network has an Airport Extreme w/Time Capsule as the base and then an Airport Express and a second Airport Extreme to reach different areas of the house. Is there a way to use the second Airport Extreme for file storage on this network?

My home network has an Airport Extreme w/Time Capsule as the base and then an Airport Express and a second Airport Extreme to reach different areas of the house. Is there a way to use the second Airport Extreme for file storage on this network? Network is administered through an iMac running OS X Yosemite 10.10.2. Ideally, would like for the second Airport Extreme hard drive to appear on the list of devices in the Finder window.

Ok.. gottcha
The problem is network wise.. Yosemite is about equal to tin cans and string.. pathetic.
Here is my usual set of instructions to get anything working on Yosemite.
The best way to fix problems is a full factory reset of all the AE in the network.
Factory reset universal
Power off the AE.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the AE to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg AEgen5 and AEwifi for basestation and wireless respectively.
Even better if the issue is more wireless use AE24ghz and AE5ghz with fixed channels as this also seems to help stop the nonsense.
2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. Ensure the AE always takes the same IP address.. this is not a problem for AE which is router.. it is a problem for AE which is bridged.. you will need to set static IP in the main router by dhcp reservations or use static IP in the AE which is tricky.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric..
5. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.
6. Now mount the disk of the second AE in finder... manually.
Use Go, Connect to Server and type in the AE ip address.
SMB://10.0.1.2
Where you will replace that address with the actual address. The network resource should be discovered and then it will request the password.. type that in and make sure you tick to save it in your keychain.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
Do as much as you want of the above... not all of it is necessary.. only if you want it reliable.. or as reliable as Yosemite in its current incarnation can manage.
The most important thing is point 6.. mount the disk using direct IP address and not names.. dns in Yosemite is fatally flawed.

TS1843 I am getting the following error messages- No DNS Server and Double SAT. Can anyone walk me through a fix?

Airport Express- No internet connection. I am getting the following error messages- No DNS Server and Double SAT. Can anyone walk me through a fix

Try putting these numbers in Network>TCP/IP>DNS Servers, for the Interface you connect with...
208.67.222.222
208.67.220.220
Then Apply. For 10.5/10.6 Network, highlight Interface>Advanced button>DNS tab>little + icon.
Might also put them in the Airport Express, no idea what Double SAT is!?

How to configure Time Capsule for Automatic Backup AND HARD DRIVE USE

I tried to configure Time Capsule for back up and as a hard drive. I record music and need to copy the music myself onto an external hard drive for speed, so I want the TC to double as an external hard drive, and do the back up. I want to be able to open the TC as a hard drive, to open my songs from it. Can it do both?

I finally figured it out. I am able to access my TC from the "shared folder." When I click on it, I get the "connection failed message." I failed to notice the login button in the upper right -- user error due to my Windows based education. The button is very subtle. Once I login, I can create folders and add content.
I didn't see a partition option. Where is that? Just curious.
Thanks!

Is it possible to set up Time Capsule on one network and then access its stored data (movies) using Back to My Mac from another network that also has Apple TV to play them?

I recently purchased a Time Capsule to store data at my office. I have an Apple TV at my home that I would like to start using to play my movies. With the storage of the new Time Capsule, I am curious if I can somehow store my iTunes movies on the Time Capsule at my office and then use Back to My Mac to access the TC from my home and then play them via Apple TV. Does this sound possible? We have an iMac at the office that remains on 24/7 connected to the TC.

ATV cannot play movies from the TC, even if it is on your home network.. ATV is a streamer.. it is not a media player.. and the TC is a dumb as a board hard disk in a router.. so it has nothing in it either.
You cannot play movies from ATV without itunes, which streams to the ATV.
If the iMac is running 24/7 then you should be able to connect to the iMac remotely and run from iTunes on that, which could then play movies stored on the TC.. with the following issues.. if you use wireless on the iMac forget it. The iMac has to be ethernet connected as it has to pick up the movie on the library and play it back to the TC to network to your home.
The next issues is speed of slowest connection.
Your download to your home maybe great.. what is the upload speed from your office like??
If you pay for uploads and downloads you will pay for the movie 3x.. first to download it.. second to upload it.. office to net.. and third to download it again.. net to home.. Sorry but it is better to play the movie directly from online itunes store.
If you plan to try and play non-itunes movies over the connection, it won't work.. ATV as stated is linked to itunes and cannot play movie files.
Overall this sounds like you need to think it out a bit more.

How to Set Up Time Capsule With Airport Extreme and Airport Express

Just got a new 1TB Time Capsule. I want it to be the main base station for my network. I already have a network set up with an older Airport Extreme base station and an Airport Express to extend it. I am thinking that rather than setting up the Time Capsule to "join" the old network, the best approach is to disconnect the Airport Extreme and Airport Express and reset them. Then set up the Time Capsule as a brand new network and bring the reset Aiport Extreme and Express onto the new network as if my original network never existed.
Is that the right approach or am I complicating it? Can I just join the Time Capsule to the existing network and still make it the main base station for the network?

I'd first use AirPort Utility to "Save a Copy As" of your AirPort Extreme settings. Then disconnect it, connect the Time Capsule in its place, and use AirPort Utility's "Import" function to read those settings. (Both of those functions are under AirPort Utility's "File" menu.) You may have to adjust a few settings. Once you have the Time Capsule working as you want, you can reconfigure your AirPort Extreme unit as you wish.

I am planning on using my time capsule as a network and essentially an external hard drive - not just back up, is this ok?

Most users should use the Time Capsule for backups. This assumes that "original" copies of your data are on the computer and backups of this data are stored on the Time Capsule.
If either the Time Capsule or the hard drive on your computer fails, there are at least copies of your important data on the other drive.
If you are asking if you can place "original" files on the Time Capsule, do you have a plan to backup those files?
If the Time Capsule drive has a problem....and your only copy of your important data is on the Time Capsule....you will lose everything.
If you are asking if this is OK, the answer for most folks would be "no".
Can you clarify if this is what you are asking?

How to use time capsule as hard drive and connect with existing net gear router

I have a netgear D6300 router, which i use to connect to internet - which is excellent so far for my downloads and games etc for my PS4 and hence am keen to continue using it. I bought the Airport time capsule for wireless storage, and when i set it up, I was advised on setup to connect the TC to my router, and it did what it needed to do.
Now, in order to connect to internet, i need to connect wifi to net gear router, but to access time capsule, i need to change wifi connection to my newly created wifi network with TC.
I want to use TC as a backup storage for my mac (its a 3TB TC), but also, my laptop has only 500gb hard drive which is now half full from downloads, so i want to transfer all my downloads to my TC and use it as an external hard drive, and future downloads to TC - but when i connect to wifi of TC, i can copy my folder on my mac, but not paste it to TC in finder. (the only thing in TC is an image of tmg of my macbook from first backup.).
How do i use TC as an external HD - there wasn't much difference in price of external wifi/wireless HD between non-TC and TC at 3gb, so i just thought i'd go for the airport TC option.
And is it possible to keep connected to wifi internet via net gear router, AND wifi TC - the whole point i bought it (from US shipped to australia on eBay, therefore not able to send back) was to use TC as external large HD via wifi, but keep my net gear router going.
Surely there is a way to not having to flick between wifi connections of TC and net gear internet.
When i'm connected to TC, i can't access internet, only TC.
And I don't really want to connect TC to my router via ethernet cable, as too many cables.
This can't be a difficult situation to manage, but i'm not sure how to do it.
Thanks

And I don't really want to connect TC to my router via ethernet cable, as too many cables.
Sorry but you have very little choice.
The TC can join to a wireless network.. but it is flakey, poor, slow and highly NOT recommended way to do things.
Nevertheless if you want to give it a try .. here is the method.
How do I setup my time capsule with wireless internet?
You SHOULD, plug the TC into the Netgear and run it in bridge mode.. you set the wireless to create a wireless network.. then when you connect to the TC it will be also connected to the internet and fast.
(if you don't do that you may as well have used a USB drive plugged into the Netgear, as it would be just as good).
TC is not actually designed for mixing Time Machine backups and files.. but if you are just storing downloads that is ok.. but I strongly recommend you use a DMG or sparsebundle to prevent the TM and the data from messing each other.
See Pondini instructions here.
Q http://pondini.org/TM/Time_Capsule.html

I like the idea of auto back-up for my new iMac, Ipad and PC Netbook, particularly if I can access all files and data stored on any device. But I have a Conceptronic router. Will Time Capsule work with this and how?

I like the idea of auto back-up for my new iMac, Ipad and PC Netbook, particularly if I can access all files and data stored on any device. But I have a Conceptronic router.
1. Will Time Capsule work with this and how?
2. Can my printer USB be plugged in and then shared between the devices?
3. Can I create a network and how?
4. What happend when a visitor logs onto my existing wireless router?
I'm new to Macs (well a returning user having started with Mac Plus!!) and not very technical. Any help / advice will be much appreciated.
Ray

The key to what you seem to want to do is to be able to get Apple's Time Capsule router to "join" the network that your Conceptronic router. I believe that works with some third-party routers, but I've never seen a list of those that work in such a configuration and I have no experience with Conceptronic equipment.
You might be better off with a Network-Attached Storage (NAS) device instead of a Time Capsule.

I have two time capsules, one for work and one for home, how do I set up the work time capsule to only back up my work files?

I have two time capsules, one for work and one for home, how do I set up the work time capsule to only back up my work files? Also, how do I add co-workers to my work time capsule and wife to my home time capsule? Thank you!

You cannot have two different TC setups.. at least until Mountain Lion.. it did introduce some changes but I am not sure if you can setup two different configurations for TM.. you can use two different devices to back up to. I doubt this will help you.
You might be better using a real backup software.. superduper, CCC, chronosync etc.
The TC by default is available to any Mac in the network to do backups. TM will sort itself out and put each computer on a different backup. These are kept in separate sparsebundles.. so that is all fine.

HT3728 Optimisation of Time Capsule 1tb, Apple TV and bt broadband

Please can you offer advice on the correct configuration for Apple Time Capsule (1tb), Apple TV and bt broadband hub that will provide the optimum performance of the wireless broadband and the hardware.
Thank you in advance for your advice/response.

The TC should plug into the BT hub by ethernet to WAN port..
The TC will be in bridge mode.
You will create a wireless network in the TC.. It is then up to you if you use the same SSID =Network name as the BT Hub or a different name.. the roaming network should work fine.. but sometimes it is easier to just turn off the wireless in the BT Hub and just use the TC.. a bit of trial and error here is the only way to find out.
What do you hope to do with the TC other than wireless network?? It is really not able to store movies etc.. because the ATV is not a media player .. it is a streamer. You need something like a computer or ipad to stream to the ATV. (Unless you JB a Gen1 or Gen2 ATV).
