Performance of Time Capsule and "device not found".

I am now on my 2nd TC average weeks because I thought the first was broken-, but I get the same questions on the second >

  1. A Wi - fi connection is very intermittent.  Seat 3 feet of the TC, I can get 450Mbps on my iPhone 6 and 5 minutes later her stockings to 2Mbps or less (measured on the Wi - Fi Sweetspot app).  Similarly, the speed of connection internet test ranging from 20-30Mbps until 0.3Mbps not it depending on the strength of the wifi.
  2. Air utility sometimes connection works and see the TC.  But often it is not.  First he asks the password, maybe 2 or 3 times.  Can I get a yellow triangle showing on utility AP with "Device not found" and the only option is to Forget.  The TC IS still there, but since I use it for ethernet and wifi internet access still works because I am always online.

So, what speeds SHOULD I get the Wi - Fi, 3 feet of the TC - I would have thought higher?

Why WiFi speed decreases considerably, sometimes in the same place?

Why the Airport utility is not the device, when it is still there?

Is this a general problem with TCs?  Is this another duff, one back?

Thank you

Update you the firmware to 7.7.7 in the TC?

If all tests performed 7.7.7 then downgrade the firmware to 7.7.3 as he could work much better.

If it still fails I just return it.

They seem to vary a lot in quality of construction. Some work OK but many have problems... and when you Exchange to the same store you get another from the same lot.

There are a lot of articles on wireless diagnosis.

for example, from your Mac.

Use Wireless Diagnostics helps you troubleshoot Wi - Fi on your Mac - Apple Support

Follow the wireless in a few days... and use ethernet if possible... Wireless is never a reliable substitute for ethernet.

iOS

If your iPhone, iPad or iPod touch connects to a Wi - Fi - Apple Support network

A lot of wireless issues with each new version of iOS... he could so your phone that is the problem, not only the TC.

You should check how wireless is around you and the intensity of the signal of all devices.

I also need to know the exact of the TC configuration and your network if you want to find the problem. Although problems with the Wi - Fi in the TC would be not at all unusual.

  • Airport Time Capsule device not found

    I have the time Capsule on the airport of the TB 3 802.11ac (bought 9/2014).  It integrates the latest version of the 7.7.7.  Just last week, I received the error device not found (.. .has been previously a part of your network... etc.).  The internet connection is always good and the component of the time capsule router still works.  When I unplug the device, it can find him but eventually will go down in a few minutes.  I also did a warm reboot, but some results.  Printer connected to the time capsule does not, nor does Time Machine back ups.

    Would be grateful of any advice on why the drive not found error continues to occur.  Thank you!

    You have Back to My Mac enabled on the Time Capsule?

    If so, turn it off for the moment in the AirPort Utility and restart the time Capsule.

  • How can implement you not with Tim Capsule and AirPort their simulation on the iMac?

    Hello

    How can implement you not with Time Capsule and AirPort their simulation on the iMac?

    I don't know what you're asking.

    AirPort Extreme is a wireless router.

    A Time Capsule airport is an AirPort Extreme with a built-in hard drive for data storage.

    An iMac is a Mac computer.

    An iMac is not a wireless router, so he is unable to perform the functions of a wireless router.

    Apple Extreme, Time Capsule and Express on the same system, what is the best way to set it up so that all devices smoothly from one end of the House to another?

    I'm going to assume that you plan to have wireless devices.

    Let's say that the Capsule is your "main" router  If this is the case, then it must be located in the House, so that the distance between the time Capsule is the same for the outside walls of the House.

    Then, on the 'left' side of the House, looking for an airport to midway between the Capsule and time of the outer wall of the House. Do the same thing the 'right' side of the House.

    In other words, each of the two airports that "extend" the wireless signal are located at equal distance from the Capsule of time... but they are in opposite ends of the House.

    If you intend to interconnect all the airports and Time Capsule using a permanent, Ethernet wired... which by far is the 'best' way to put in place a network in terms of performance and reliability... then you can locate one of the devices anywhere you want.

  • Device not found Airport Extreme

    We have an airport extreme connected generation via Ethernet to a switch that provides network access to our entire House (about 10-15 connections) via wifi access points all Ethernet hard wired (linksys + apple) and a direct wire to a PC. Airport extreme is the dhcp and is connected to a gpon fiber using PPPoE.

    The problem now is that the AirPort Extreme disappears from the airport on iOS Mac utility and Windows, it is found however the network and the Internet continues to operate normally on all connected devices. I can also continue ping on the router.

    I have reset the AirPort Extreme to the default settings, but the problem continued...

    I tried to unplug all devices and have AirPort Extreme only connected to him have the fiber but the problem persists...

    no idea how I can fix this problem?

    You describe a known problem with Back to My Mac which first appeared around July 13. The problem manifests itself in a message "Device not found" meant to be displayed in triangular AirPort your AirPort base station with a yellow icon utility, while the router of the device functions others continue to work normally.

    If you use an airport Time Capsule, backups will not work using that device or USB hard drive units connected to it.

    Apple will only be able to solve this problem, so all you can do is wait for them to do. If you want to contact them to tell them about it, using the contact Support link.

    There is a solution: on a Mac, open AirPort Utility and select file > configure other...

    For each of your routers Apple AirPort Base Stations serving their respective networks: its IP address and password (if you don't know either of them, read the Note that follows the horizontal rule below). Then, on the tab of the Basic Station , delete all the entries in the Back to My Mac using the 'negative' button, then click on Update.

    Which must be re-established appearance of this base station in AirPort Utility, as well as in a side bar of the Finder, if all shared disks are plugged on. It will also restore possibility of Time Machine to save on these discs, if this has also been a problem for you.

    If this seems to imply that you will not be able to use Back to My Mac until Apple fixes it, you are probably right. Well to diagnose problems of the CCMM is tedious work that I have not yet finished.

    Apple does not participate on this site except in a very limited way, so don't expect is not a response from them, here or elsewhere for that matter. We'll just have to wait for them to fix it.

  • Airport devices not found

    Hello! I have two devices from the airport: on the one hand at home and a time in my lab Capsule. I was away for 20 days and yesterday, when I came back, there was a problem with the two: my Mac cannot access these devices, they can connect to wifi networks hosted by them. When I try to access these devices via Airport utility, I get the error message "device not found". This message, both at home and in the laboratory, tells me that the device was part of my network before, and that I should check if it is within its range. There is an option to 'forget the device' in the end. It is quite strange, as other Mac networking for my laboratory do their backups normally during my absence. Could you please help me? Thank you.

    This was reported once many here recently.

    A 'solution' refers to those who have set up their base stations for Back to My Mac. If you did, how to follow recommended action is temporarily remove or disable this option, as follows:

    • Run the AirPort Utility.
    • Select the base and then station, select change.
      • Note: You may need to use the option "configure others...". "to access the base station. Enter the IP address of the base station, the default value is: 10.0.1.1 and base station administrator password when you are prompted.
    • On the tab of the Base Station, go back to the section of my Mac at the bottom of the window.
    • If you have entries here, select it and click then the minus sign "-" button to remove it.
    • Click on update and allow the base station restart.
  • Device not found, but internet work

    I have an Airport extreme with a capsule 2 TB that I use as a backup file.

    All of a sudden I can't connect to the airport time capsule. When I launch the airport utility, there is an orange triangle/exclamation point that fits the description "device not found". The router works well, since I am connected to internet (at this time).

    I tried to unplug the unit and time capsule comes back for about 2-3 minutes until the same problem occurs again. Factory of Soft and hard resets produce the same results. I know this isn't my macbook pro because it does the same thing on my phone as well.

    You have Back to My Mac configured on the TC with your AppleID?

    This has happened to me and when I removed my AppleID and disabled Back to My Mac it ceased to occur and the TC became visible again.

    I hope that Apple will fix this soon but it would pay record a call of support with Apple on this topic as well.

  • Device not found in airport 6.3.6 utility

    Running a 5th generation I'm stuck. I checked a bunch of other posts and restarted all devices, as well as reset the base station. I also adjusted IPv6 at the local level.

    When I pull up the Airport utility, I get "device not found" and cannot connect to the base station to adjust settings. What is weird is I can get temporarily in Airport utility if restart my MacBook and the base station at the same time. However, it does not last long. I also see the drive mounted in the Finder all the time. A Wi - fi connection works without interruption.

    I tried this on 2 Macbooks, an ipad and an iphone. El Capitan running. I am at a loss.

    Someone at - he was able to solve this problem.

    You are one of the many ad today with this problem.

    for example. There is only one thread.

    Time capsule not recognized in the utility of the AP

    I suggest that you can still access the AE or TC using configure others and type the IP address.

    A 5th generation is the flat and quite old but more reliable than Gen6. But beyond 5 years they get flakey.

    If you mean a 5th Gen TC then this is the newest one.

    I am surprised, he's also missing on the iOS but who was more reliable version of airport utility.

    I have an Officejet 4500 with a wired Ethernet connection. For some reason any, that my computer has ceased to be able to scan from it, I can still print and everything very well. I don't remember to make changes to the system and other computers on the network can always analyze without any problem. I restarted my computer, unplug the printer, uninstalled and reinstalled the software, active windows firewall settings and cannot find any reason why it won't work. I am running Windows 7 64-bit on the computer that does not work, the other computers on my network that still work are running windows 7 64 bit and XP. On the "HP Imaging device not found" error message that opens under more information, I get this: 8 [(1, 0,-2147221496)]

    I've lived the HPSDU and he said: there is a problem with the driver and he cannot communicate with the product. He said also it is impossible to scan with windows WIA, and finally it's the Twain component may be damaged. I have uninstalled, reinstalled, re-downloaded the Installer off the HP site several times, but can not solve this problem. Help, please.

  • Backup to Time Capsule and an external hard drive

    Hi all

    For several years, I use as a router Time Capsule and a backup device. Recently I found information about to associate an additional external hard drive for backup. For me it's a backup just to be sure when my Time Capsule would fail.

    I found information on the internet that it was easy to switch between the two devices. I connected the external hard drive in the time Capsule.

    But after installing the external hard drive my Time Capsule is not able to back up more!

    Please, could you help me find a solution. It would be great for me.

    Many thanks in advance,

    Diana

    I suggest that you get first back ups goes again on the Time Capsule, then we can discuss adding the USB key as a second backup source.

    For now, if please power off the power and unplug the USB of the time Capsule.

    (Gear on the dock icon)... open Mac system preferences, then open Time Machine

    Make sure that Time Machine is running

    Click Add or remove disks

    Under the backup drives, make sure that the Time Capsule disk (named 'Data', unless you have changed the name) appears

    If it isn't, then click data under available disks

    Then, click on disk use

    Close the window and now, click the 'clock' Time machine at the top of the screen

    Click on NTI Backup Now and who should get backups start on the Time Capsule

    After the return when you have confirmed that this is the case

  • Time capsule and extreme; Cannot create the roaming network

    Problem: when you try to create a network roaming with time capsule and extreme, the wifi hangs and the network is up and down. Here are my deets:

    TC and extreme as well have the latest firmware of the 7.7.7 are the latest generation of products, purchased in the last 12 months

    TC is connected to Arris SB6183

    ISP is Cox North san diego County

    TC is then connected to the netgear GS105. (upstairs)

    NETGEAR GS105 then connects to GS108 (down in the patch panel in the closet of the master bedroom)

    1 x GS108 port connects to extreme

    I can get the stable network and works correctly as long as I don't have connected and extreme.

    I followed the instructions provided by apple in their "how to set up a roaming network.

    I have hard reset the devices apple repeatedly in my attempt to get things to work

    I started a Wan shortly ago at the connected WiFi and that was stable and work for not more than 30 minutes and then it went offline.

    So here I am now. Unable to get back online and stable with two apple devices connected network.

    System was stable and working well before the upgrade to 7.7.7. I had a wifi connected network not a roaming network at the time.

    Any suggestion would be great and really appreciated.

    Thank you

    After screenshots of the TC and AE installing airport utility.

    I suspect that you simply have something set wrong...

    Main error is to use extend wireless when it is connected by ethernet... This will create a loop and bring down the network.

    The two units must be defined to create a wireless network... both must use the same name (SSID) and the same password, but must be set to different channels.

    It is almost impossible in this case crashing the network since the two are completely independent Wireless Access Points... (WAP).

    The TC must be in router mode... EI must be in the bridge (bridge mode off on the network tab.)

  • 15 15 HP - r208nl: start the device not found error (3FO)

    Hello

    I have this laptop from less-than-one-year-old (this guy: http://icecat.us/us/p/hp/l0n16ea/laptops-0889296492238-15-r208nl-26524145.html) and I have the Boot Device not found error infamous.

    I'm not sure if this is relevant, but the problem occurred a few weeks after the upgrade to Windows 10 (when bought, laptop had Windows 8.1, probably an update of Windows 7).

    Also, I noticed this basic operation to during the priming phase take a long time. For example, when I press F10, it takes about 1-2 minutes to bring up the BIOS configuration screen.

    There are a number of similar questions on this forum, but the proposed solutions do not apply to my case or simply do not work. Here's what I've tried so far, without success:

    • hard reset
    • reinstalling the hard drive
    • automated tools in the Recovery Manager (this tool you access by pressing F11 at startup) *.
    • chkdsk and identical from the command prompt (to which I have access from the Recovery Manager tool) *.

    Note that even if the material for the HP PC Diagnostics tool failed hard drive test, apparently I can access my files on the hard drive of a Linux Live CD/USB (I managed to access it during a previous attempt, do not know if it can be reproduced).

    I can't test the drive on other PCs (which I have another laptop which I can plug the drive may be defective), not I can try to connect another hard drive non-offending for verification (as I did not).

    Any suggestion?

    They gave me no installation CD/DVD (I guess I had to use the recovery partition). In case I need a new installation, how can I retrieve my serial number?

    the hard drive is not accessible, I can't access Recovery Manager simply by pressing F11, I had to use a USB recovery media

    CHKDSK and even produce this error message: "cannot open volume for direct access.

    It looks like your hard drive is not/is a failure. Guarantee would provide a new replacement - and probably send recovery media free since did you not make it yours.

    You can make a Windows 10 usb or dvd using the free download of Ms. No license key is necessary since it has been activated at the same time on the machine.
