Dual Band Time Capsule - networking issues

I upgraded from an original Time Capsule that had been running successfully on the 5Ghz band with firmware 7.4.1.
I changed my original TC out and setup everything from scratch so that the DB TC was connected to my cable modem and provided the DHCP leases. Set it to provide N only services on 5Ghz and b/g on 2.4 (I tried the automatic and the manual settings during troubleshooting). Guest networking was turned on and was serving up on the 2.4Ghz channel.
Next I moved my original TC to another room, extended the new DB TC on the 5Ghz network and everything seemed fine.
But then I noticed that whenever I started to run a TM backup (over airport or wireless) that eventually my original TC would seem to go deaf. I could not access the internet through it. However, Airport utility could still see it. On further examination I realized it had lost its IPv4 DHCP address and was only displaying an IPv6 address in the Airport Utility.
After many isolation steps and no success, I decided to move the old TC into the same room as the new DB, connect them via ethernet and turn off the wireless on my old TC altogether to prevent interference. That seemed to work. Until a TM backup was kicked off (btw - all backups right now are to the original TC not the new DB).
Finally, I disconnected the original TC altogether and just let the DB TC run everything (but still I was not backing up to it). Now the new TC by itself seems to stop allowing access to the internet. Internal network is fine. What is really odd, is that rebooting the DB TC sometimes doesn't seem to help. However, reseting the cable modem does (for a little while).
I switched back to my original TC now and everything is working flawlessly again including being able to run TM backups to it and no loss of internet access.
Any ideas? I have already exchanged it once. I have reloaded firmware (7.4.1). I have set up everything from scratch. And still it is really flaky.
Thanks in advance.

5 GHz signals are capable of faster speeds, but you always have to give up something to gain something else. In the case of 5 GHz, in order to gain higher speed, you must give up distance and penetration power with 5 GHz.
Bottom line...5 GHz signals are significantly weaker than 2.4 GHz signals. Your Mac is looking for the strongest, best quality signal, so it connects to the stronger 2.4 GHz band at the upstairs location.
For most of us, 5 GHz is pretty much of a line-of-sight deal. If your Mac has a clear look at the Time Capsule, and it is relatively close to the Time Capsule, it will likely connect to 5 GHz.
Otherwise, if the signal must pass through a few walls, or a ceiling (which is much thicker than a wall) the Mac is very likely going to connect at 2.4 GHz.
If you take the Mac downstairs and give it a clear look at the Time Capsule from 10-15 feet or so, does it connect at 5 GHz?

Dual-band Time Capsule is, practically, useless, only if...

Hi everyone!
It goes like this: I bought a dual-band 2TB Time Capsule. I configured it and gave "2.4Ghz" as the name for the 2.4Ghz network. Then I went to "More Options" and named "5Ghz" the... 5Ghz network. They show up in the wireless networks list and seem to work fine, but...
Even though I put "5Ghz" above "2.4Ghz" in the preferred networks list ("System Preferences/Network/Advanced") the laptops (one MacBook Pro and one Air) always connect first to the "2.4Ghz" network. Only if I remove it all together for the network list do they connect by default to "5Ghz". And even so, sometimes I find myself on the "2.4Ghz", with no logical explanation, as it is no longer in the "known" network list. The only reason I bought a dual-band Time Capsule was to keep my compatible hardware on the 5Ghz band, for maximum speed, but still to be able to offer a wireless connection to older hardware (like an iPhone).
But it's not working out, does it... It only seems normal to me that 5Ghz compatible hardware connects always to the faster network and I really don't understand why OS X let's faster hardware to connect to a slower wi-fi connection.
So, what can I do to force the Pro and the Air to always connect to the "5Ghz" named... 5Ghz network? Did I miss something when configuring?
And one other thing: if I don't give a separate name to the 5Ghz network and, theoretically, let Time Capsule do all the management, the laptops still don't use the 5Ghz band, which they should. At least in my logic...
Thanks.

Well I did that, but on the Air the first thing it did - after I removed the password from the keychain and the preferred network list - was to connect to the 2.4Ghz network... :)) I connected manually to the 5Ghz network and restarted the system again. This time in the keychain appears the 5Ghz network and it did connect to it by default.
No such issues on the MacBook Pro, but somehow I feel it's a matter of time until they're gonna connect to the g network again...
The management of the dual-band Time Capsule is very weak... We should have had the option to give a different password for the 5Ghz network from the beginning...

Cannot connect Airport Express N to Dual Band Time Capsule at N speed

Long time reader, first time poster. I am usually pretty good at solving my problems without posting, but I have been attempting to solve this problem for a while without success, so here it goes.
I have a dual band Time Capsule that I want to run at 5Ghz N and 2.4GHz b/g/n (using the OPTION key when selecting "Radio Mode" to select this option). This runs fine on its own. However, I also want to set-up a new Airport Extreme N to run as an extender for the 5Ghz network, and here is where I have problems.
I have already set-up the 5Ghz network to be under a separate SSID. I have also selected to use Wide Channels, Multicast Rate=High, and Transmit Rate=100%. I have also been sure to make sure that I have selected "Allow this network to be extended" in the TC. As of yet, I have not even attempted any WEP/WAP key security, and the SSID is visible.
When I attempt to connect the AEx as a repeater (using the "Extend a wireless network" option on the AEx) the AEx will not see the 5Ghz network name. It will only allow me to select the 2.4Ghz SSID, even though I have a distinct SSID for the 5Ghz.
Note: both my iMac and my AppleTV can see and connect to the 5Ghz network. I am attempting to set-up the AEx right next to the TC before attempting to see how faraway I can move it.
I have additionally tried to set-up the AEx to repeat the 2.4Ghz network. In b/g/n mode it will repeat, however it only ever seems to get the g speeds. If I set-up the TC to only do N networks (ie one SSID as the 5Ghz N Network and one SSID 2.4Ghz networks) the other clients (the iMac and the AppleTV) can see and connect to each, however the AEx won't connect at all.
What am I doing wrong? I feel that I have been very thorough with my approach. Any help would be very welcome.

Welcome to the discussions!
I don't have a solid answer yet to your issue, but would offer a few comments that might help sort things out.
I'm confused by your statement that you are able to extend the 2.4 GHz network, because the dual band TC does not allow the guest network to be extended. Check AirPort Utility - Manual Setup. Click the Wireless tab. I don't have a dual band TC, but I believe if you click the Options button, you will see more info about extending.
While there is a check box next to "Allow this network to be extended" for the main network, there is not a check box for the "Guest" network. It's not there, or least it's not there in the guide that I'm looking at.
I suspect that your computer was picking up the 2.4 GHz network from the TC, not from your Extreme. To verify this, open AirPort Utility again and click on Manual Setup for the TC. On the summary page, note the MAC address for wireless on the TC. Now, do the same thing for the Extreme.
Use your computer now to check things. Hold down the option key and click on the Airport icon at the top of the screen. The MAC address of the device that you are connected to will be displayed.
Have you tried to move the Extreme to a more remote location? You note that you have the two devices, TC and Extreme very close together. As a test, position the Extreme approximately half way between the TC and the area that you want to extend to and see if you can connect with your computer. Check to see if your computer is connecting to the Extreme or the TC by holding down the option key as above.
You have probably already done this, but check on the setup for the Extreme using AirPort Utility - Manual Setup - Wireless tab. There is a check box either on the Wireless page or the Options page to "Allow wireless clients". This must be checked for wireless clients to be able to connect to the the Extreme.
Post back with your findings and we'll try to figure this out.

New dual-band time capsule but computers only access 2.4ghz channel

Just set up a new dual-band Time Capsule (bought it prior to the latest release though). Everything is working so far - Time Machine, wireless internet - but I noticed that both computers in the apartment (2 Macbook Pros - one running 10.5.6, the other 10.6.1) are only accessing the wireless network on Channel 2 (2.4Ghz). And on the laptop running Snow Leopard, I'm only seeing transmit rates of between 50-100. On the Leopard laptop I see up to 130. Doesn't this suggest that the computers are only using the "b/g" band and not the "n" band? When I option-click on the airport menu icon on the SL laptop it does say PHY mode is 802.11n, but I have no idea what PHY mode means frankly.
I feel as though the laptops should be connecting on a much higher channel and seeing much higher transmit rates (closer to 300?), but I'm not at all well-versed in these wireless realms. Any help would be much appreciated...
thanks
Tom

Welcome to the discussions, Thomas!
+"And on the laptop running Snow Leopard, I'm only seeing transmit rates of between 50-100. On the Leopard laptop I see up to 130. Doesn't this suggest that the computers are only using the "b/g" band and not the "n" band?"+
If you were receiving "g" rates, the number would be 54 or less depending on the distance from the router to the computer, so you are seeing some "n" speeds from the 2.4 GHz network. I believe the default setting for this "guest" band is 802.11n (802.11b/g compatible).
Would suggest that you contact Apple as a number of users have reported that either the main network or guest network is not functioning correctly.
The default setting on the main network is 802.11n at 5 GHz, so if you have a good connection and are relatively close to the router, you should see speeds in the 200-270 range.
Many users assume that 5 GHz is a stronger signal, but the facts are that 5 GHz signals are absorbed by walls and obstructions much more quickly than 2.4 GHz signals, so depending on your home construction, distance from router, etc., the 5 GHz signal may not be strong enough. Your computers will connect to the strongest signal. If that's the 2.4 GHz band, that's where they will connect.

Time capsule network issue

I am a tech (windows and linux) and had one of my customers call me about building a network for him using a time capsule he purchased. He is running two macs dual booting mac os and windows, a windows PC and a lexmark printer. I got the network running using the time capsule as a NAT router to share his internet connection.
We are using account based security on the Time capsule harddrive and a mix of wired and wireless clients.
I can initially access the share but after a few minutes or accessing from several machines the share is no available (an access attempt eventually times out) I also can no longer browse the windows network. In this state I can access the internet through the time capsule with out a problem and can print to the printer (IP based addressing) but cannot browse network resources by device name or open the time capsule share.
I can open the time capsule with the airport utility and make changes but this does not make it become available. I can only get the network back by pulling the power on the time capsule and restarting it.
Can you give me any pointers or suggestions?
Thanks

Suggest that you follow this procedure to delete the current wireless network settings on the Mac, as they may likely be corrupted.
Open System Preferences (gear icon on the dock)
Open Network
Click on AirPort on the left
Click Advanced at the lower right
Locate the name of the wireless network and click it to highlight it
Click the - (minus) button at the bottom of the connection list
Click Done
Click Apply
Open Macintosh HD > Applications > Utilities > Keychain Access
Locate the listing with the name of the wireless network
Right-click it, then choose Delete
Shut down your your Mac and then power it back up
Try to log on to the network again. You will have to locate the name of the network and enter the password to join

Apple Tv - Airport Express - Time Capsule, Network Issue

Hi,
I don't know if I'm on the right thread but I don't know in which one to post my question.
I have the following configuration in my home:
Floor 1 :
- ISP connection, connected to Airport Extreme.
Airport Extreme has the Network name : Floor 1 Network
Floor 2 :
- Airport Express connected via ethernet to the Airport Extreme from Floor 1.
- Time Capsule extending the Airport Express.
Airport Express and Time Capsule are on another Network name : Floor 2 Network.
All is working perfectly. (Clients wirelessly connected are MacBooks, iPhones, iPads, iPods, Apple TVs)
Here is my problem.
I have an Apple Tv on Floor 2
The Time Capsule is located not far from the Apple TV (line of sight, few meters)
The Time Capsule hold my movies
Sometime I have problem to sync the ATV (very very slow). I already restart ATV, and TC. But sometimes, cannot get better a thruput
I would guess that the Apple TV would sometime connect to the AE (which is further than the TC), and then create this problem.
I would like to make sure that the Apple TV connect wirelessly to the TC and not the AE.
How could I do this, knowing that TC is extending the AE wireless network, I cannot select from the AppleTv on which wireless node to connect.
Thanks a lot for the support.

fleyne wrote:
Yes. Actually, when the thruput is not good, I check first that my book is properly connected to TC and not the AE. This by checking the BSSID.
How could I do this on the ATV ? Or How could I make sure that the ATV is wirelessly connected to the TC?
It probably won't show you everything you'd like to know, but you can learn something about the ATV connection with AirPort Utility. Enter "manual setup" mode, select the menu option Base Station -> Logs and Statistics, then select the "Wireless Clients" tab. That should show you the signal strength and noise for each client.
I would like to avoid to run ethernet cable between the TC and the ATV.
Then you might benefit from a powerline adapter as suggested by the post from "Jolly Giant".

Can you add new AirPort Express Base Station Simultaneous dual-band 802.11n with a 1st Gen time capsule network

Hi
Has anyone tried using the AirPort Express Base Station with a first generation Time Capsule and used it to extend their network, while still being able to use the Simultaneous dual-band 802.11n on their network?
Thanks in advance

The first generation Time Capsule was not a simultaneous dual band device.
If you add the "new" AirPort Express to the network and configure it to "Extend a wireless network", it will extend the one single band signal that it is receiving from the Time Capsule.
In other words, the AirPort Express will not extend simultaneous dual bands in this type of setup...since it can only "extend" what it receives. You would need a simultaneous dual band Time Capsule if you want that type of functionality.

What is the proper way to extend 2nd generation time capsule network to 2nd generation Airport Express?

I have a Simultaneous Dual Band Time Capsule. Up until now, I have been extending the network with the Airport Express (2nd Gen, the 802.11n model). Since it was not simultaneous dual band, it was extending over the 2.4 GHz band so as it could extend b, g, and n and support my iPhone at 2.4 n as well as my iPad and MacBook Pro at 5 GHz.
I just bought the new simultaneous dual band unit, which theoreticalkly should be able to extend both bands.
Now, it is not that simple. I also run a guest network, which I assume also gets extended when WDS is on. I also still have the old Express which I have relegated to another part of the house.
When I set up the new Express, it asked me which one of the networks I want to join, either <SSID> or <SSID 5GHz>, the automatically generated name for the the 5 GHz band on the Time Capsule. Which one do I join? How do I know that both are extended? When I connect to the <SSID 5GHz> now my iPhone can see that one and connect to it, so I am assuming it is NOT going at 5 GHz.
And I have no idea at all what the guest network is doing....
Does anyone have any insight into tthe proper way to configure all the units, and what I can expect? My network is as follows:
Airport Express (Simultaneous Dual Band)
Cable Modem > Time Capsule (Simultaneous Dual Band) >
Airport Express (802.11n, last gen)
I want to run guest network (hopefully simultaneous dual band) and personal network. I want the new express to run both bands just like the Time Capsule, and for the old express I want to know which of the two bands I am extending.
Thank You!

I also run a guest network, which I assume also gets extended when WDS is on
Unfortunately, the Guest Network cannot be extended.
When I set up the new Express, it asked me which one of the networks I want to join, either <SSID> or <SSID 5GHz>, the automatically generated name for the the 5 GHz band on the Time Capsule.
This likely indicates that the Time Capsule has been setup to use separate names for the 5 GHz and 2.4 GHz bands, instead of the default, which uses the same wireless network name for both bands.
In order for the AirPort Express to be able to extend both bands, the Time Capsule will need to be configured so that both bands use the same wireless network name.
Then, configure the AirPort Express to extend the wireless network name of the Time Capsule, and it will extend both bands. At least, that is the way an AirPort Extreme works, and I assume that the Express is the same. I don't have an Express here to test, but will in another day or two.
The location of the Express is important, since the 5 GHz signals are not as strong as 2.4 GHz signals. You may need to experiment by placing the Express closer to the Time Capsule than normal. With an AirPort Extreme, I find that the Extreme must be located no more than about half the distance from the main router to the area that needs more wireless coverage.
If you continue to use the previous model Express to extend as well, it too must be configured to extend the wireless network name of the Time Capsule. Configured this way, the Express will extend the stronger of the 2.4 GHz or 5 GHz signals, so it will likely extend the 2.4 GHz band unless it is located close to the Time Capsule.
To find out which band the previous model Express is extending, locate a Mac laptop close to the Express and hold down the option key on your Mac while you click on the AirPort icon at the top of the screen. The info displayed will indicate whether you (and the Express) are connecting using 2.4 GHz or 5 GHz.

Extend Time Capsule network with another Time Capsule

Hi guys.
Like the title says: I want to extend the wireless network of the dual-band Time Capsule (2TB) with a first generation Time Capsule (500GB).
So, I opened AirPort Utility, selected the older model and completed the logical steps (extend another network wirelessly), but it doesn't restart. It hangs there, with the orange light blinking...
What should I do to make it work?
Thanks.

Welcome to the discussions!
Check your settings as follows:
On the 2TB Time Capsule, open AirPort Utility - Click Manual Setup
Click the Wireless tab below the row of icons
Wireless Mode = Create a wireless network
There must be a check mark entered next to Allow this network to be extended
On the 500GB Time Capsule, open AirPort Utility and click Manual Setup
Click the Wireless tab
Wireless Mode = Extend a wireless network
Wireless Network Name = Same name as your 2TB Time Capsule
Enter a check mark next to Allow wireless clients
Wireless Security = Same setting as your 2 TB Time Capsule
Wireless Password = Same password as your 2 TB Time Capsule
Update to save settings

Can I create separate folders to save media on my Airport Time Capsule? Issue is I have a 256GB HDD Mac Pro Retina which is almost full. TC will only take backup of my HDD. So where would I save my photos and videos from my iPhone and iPad?

It is a hard one.. laptops with small drives are a pain.
What you need is a home media server.
Some people use a PC running itunes for cost.. but that is nothing like as good as using a Mac mini.. they make great little HTPC device.. you can plug in large hard disks and store all your files and media. And share it with the network.. Read up apple's instructions on home sharing.
https://www.apple.com/au/support/homesharing/
For cost you can buy a mini from 2011 or 2012.. I would not recommend earlier ones.. the advantage of 2012 is they have USB3 ports. But you will pay more for them.. new mini is not as useful.. they have soldered in memory and you cannot upgrade.. the old mini was the most easily modified mac in the whole range. Uses little power and can be bought for a $300US for a good one second hand.. maybe less.

How to print from windows 7 pc on time capsule network?

I added a new pc with windows 7 on my time capsule network. Existing network includes 2 macbook pros and 1 mac mini with boot camp and windows xp. I have been using the windows xp with bootcamp on the mac mini and printing from it for a couple years. We don't share files between the notebooks and mac mini, just internet access and printing. My bootcamp side got too full which is why I added the new windows pc (yuk) for my windows programs but I cannot figure out how to get the windows pc to recognize my printer connected to airport time capsule. I installed the printer software and drivers and connected it with usb and printed but when I connect the printer back to time capsule the pc doesn't see it. Also, I downloaded bonjour from apple site but still no go. Any help is appreciated. As you can probably tell, I only know enough to be dangerous. That's why I love my Macs, they just work!

The problem is you loaded the printer directly and now do not have it plugged in.. so delete the printer in the control panel.. then setup the printer again.. this time connect to it as network printer. The bonjour should make it available as a network resource..
Tell me if you still run into trouble doing that. You may need to load the IP of the TC manually..
Window7 has higher security level than xp.. and that can sometimes also cause issues.
Are you using SMB compliant names for the TC, wireless and printer??
Can the windows 7 computer get internet via the TC? Can you ping it?
Look up how to reduce the security level in windows to match xp.. I don't remember the details but you have to do some nifty footwork.

Time Capsule: "Network name no longer available" error when copying files

Hi!
I've come upon this error when trying to copy files from my PC to Time Capsule:
"Network name no longer available".
This seems to happen only on folders that have image sequences in them (.sgi image sequences).
I was planning on transferring the content of my PCs hard drive to Time-Machine in order to smooth out the migration from my old PC to my new MBP but I have to say that I'm a little less confident about using TC as a storage space for my valuable files.
Is there a work around for this? I have tons of folders with .sgi image sequences and it would be a real shame not to be able to transfer them to Time Capsule.
Please help!

Hi… I don’t think there should be any such limitation for the file transfer wirelessly. However it can be issue, as you wired is connect at a speed of 100 Mbps and wireless connects to the max at 54 Mbps. Try to upgrade the firmware. Also try reducing Fragmentation Threshold and RTS threshold by 40 each under advance wireless settings on the router. Go to www.speedguide.net, and download the TCP optimizer. Try reducing the MTU of your wireless adapter. Please Revert Back, even if this resolves your issue.

Time Capsule Network Freezes and Locks Up

I have been having major streaming issues to my Apple TV for a few months now.
Basically, the streaming performance is poor, and after 20 or 30 minutes, the movie that is playing freezes, then the entire wireless network created by the Time Capsule stops working. Anything hooked up via Ethernet however still does work. Only the Time Capsule Network fails. This happens every time I reboot the Time Capsule. I have also started over and reset the device.
I had Apple replace the Time Capsule (gen I, 500 gig), and had my cable company replace my modem. Neither one of these things solved the problem at all. It is still happening.
I have the cable modem running into the Time Capsule, then the Time Capsule runs into a router that sends wired ethernet through various points in the house (although at this time only 1 compute is still hard wired).
I have no idea what is causing this. Could this be an Apple TV issue? Why would it cause the entire network to crash?

The issue was resolved ages ago but I don't remember how....... sorry.

Computers on my secured time capsule network? How did they get on?

When I look at my Time Capsule network, I see two computers connected to it as well as myself: workgroup and macbook c66e5 (or something like that). I have Uverse and the TC has made its own network in bridge mode. I have also set up a WPA2 Personal password. The password is 19 characters long so I know it is very secure, yet somehow these two computers are on the network. What's weird, is that I cannot see these computers or my own computer on the network from my brother's mac, yet I can see him. Also, on my uverse network, I never see these other computers in the finder. Do I have a security problem or is this normal? Thanks in advance for your help!
Kyle

I suppose access to the log is yet another thing apple removed from their toyland version 6 airport utility.. if so you will need to install 5.6.. which is a bit tricky but can be done.
Download the real utility.. not available for ML so the lion version.
http://support.apple.com/kb/DL1482
Open the DMG file to see the pkg file but do not proceed further.
Download install and run unpkg.
http://www.timdoug.com/unpkg/
Drag the pkg file of airport 5.6 utility over unpkg.. it will unpack it to the desktop in a directory.. AirPortUtility56, drill down, applications, utilities and you will find the actual utility.. drag it to your utilies directory. Now you have a REAL TOOL not a TOY.. Log is under advanced.
Then you will know what is happening instead of living in the darkness.
