Why is time machine wifi so slow

I recently switched from my dlink 655 router to the time capsule after hearing such good reviews.  I am finding the wifi very spotty and very slow when connecting to my ps3 and xbox.
Is this normal?  Perhaps I don't have things set up properly?
Thanks

2.4ghz on the TC is restricted to 130mbit.. (N lite) and although range improved on the latest model, frankly it is still nothing wonderful. If your old dlink is better keep using it.

  • Old time question: why is time machine suddenly extremely slow?

    When I ran Time machine to back up into my external drive last night, It was 50-70MB/second, but now it does not even reach 1mb/s. I tried to re-index spotlight but no help, verified disk, no repairs needed. The only thing I haven't done is to reformat my back up drive. I wanna first try to look for any other solution here (hopefully there are some) before jumping on erasing my 5 hours of backing up yesterday. . Any solution?

    Peruse Pondini's TM FAQs, for information.

  • Just upgraded to ML, and Time Machine is super slow

    Why is time machine backup so slow? Normally it took only about ten minutes...now it seems like it needs a whole day or more?!?!?!

    Hello Harold,
    Sorry to hear that Time Machine has not been backing up.  I recommend following the steps in the article below for steps to isolate and troubleshoot this issue:

  • Time Machine WIFI slows down and Fine after I unplug it?

    My Time Machine WIFI slows down to an absolute crawl and then after I unplug it and plug it back in, it's back to normal. Can someone help me?

    My Time Machine WIFI slows down to an absolute crawl and then after I unplug it and plug it back in, it's back to normal.
    This is a classic case of the effects of wireless interference from other networks around you. See the link at the bottom for more information about this.
    It might first help to understand why things improve when you unplug the Time Capsule and then power it back up. When you do this, the Time Capsule will scan to find the best available wireless channels to use at the time.
    Unfortunately, other wireless routers are doing the same thing all the time, so after a few hours or a day or two, the channel(s) that the Time Capsule was using become overcrowded and the wireless slows down to a crawl. Cordless phones can also create interference issues for a wireless network as well as any number of other electronic devices.
    Unless you can convince other users around you to turn off their wireless routers, there is not much that you are going to be able to do to come up with a permanent fix. For now, locate the Time Capsule as far away from any outside walls in your home as possible and use the 5 GHz band for as many connections as you can.
    A friend of mine who recently moved into a new apartment complex has the same problem. He has to restart his wireless router at least twice a day, sometimes more on the weekends.  Too many wireless networks.....not enough channels.

  • Why is my Time Machine running so slow?

    I am curious why my Time Machine backup is running so slow. I am trying to backup 52.85 GB. I am currently at 17.65 GB and it has taken about 6 hours. The Time Machine "meter" that shows how long it is going to take to finish the backup is telling me it estimates about 14 hours. Thirty minutes it was telling me it was going to take about 12 hours. Now 14? What's the deal? It seems to me the backup is taking way too long. What is puzzling was that the first 15 GBs or so were prett fast. You could actually see the download happening. Now it seems like the meter is stuck and not moving. Inerimittently, the meter will change the number of files yet to be backed up. Can anyone shed some light as to what might be happening.
    Thanks!

    I've followed many of the suggestions on this thread (except upgrading to Mountain Lion). My Time Machine and computer has been going for eight days straight backing up 580 gigs and last night there were 30 gigs to go! Something happened and in the middle of the night the computer crashed. I restarted the computer and external harddrive that I use for my Time Machine this morning and continued the backing up of 35.24 gigs. Except now the status window tells me it will take 9,624 days to back up!
    I ran the diagnostic command prompt:

  • Why is time machine so slow?

    My time machine is so slow and allways back up every thing again, not only the new files or changes.

    Launch the Console application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ If you’re running Mac OS X 10.7 or later, open LaunchPad. Click Utilities, then Console in the page that opens.
    Select "system.log" from the file list. Enter "backupd" (without the quotes) in the String Matching text field. Post the messages from the last backup, beginning with "Starting standard backup."
    Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Do not post many repetitions of the same message.
    Some personal information, such as the names of your files, may be included — edit that out, too, but don’t remove the context.

  • Time machine backups have slowed considerably since my installation of Mavericks -- why?

    Ever since installation of Mavericks, time machine backups have slowed to a crawl.  The message preparing backup used to to take 10 seconds to a minute, now it takes 5 minutes.  The status of the backup used to show 10mb's of 80 mb's backed up, and take under 1 minute, now it takes 5 minutes.  Finally cleaning up notice, and the time to clean up has increased significantly.  My backups go to an external HD (7200rpm) connected vis firewire 800, that has approx 180 gigabytes available of its 1 terrabybyte capacity. 

    I upgraded to Mountain Lion a few weeks ago. Everything was fine with Time Machine until a few of days ago.
    Same problem others described: extremely slow, taking hours to back up just a few MB.
    I verified the Time Capsule drive and my Mac hard drive - no problems found.
    I then erased the Time Capsule and started Time Machine. It did the full backup in a fairly reasonable amount of time (several hours, but not unexpectedly long).
    When it started its first incremental backup, it reverted to the same problem: extremely slow, but it did finish eventually.
    I then shut down the Mac and restarted (power cycled) the Time Capsule. Then I started up the Mac and told Time Machine to back up now. It backed up 30+ MB in just a few minutes, so it seems back to normal. We'll see how it goes when the next scheduled backup starts up.
    But you might try rebooting the Time Capsule (and your Mac).
    By the way, when it was in the middle of the extremely slow backup, I disabled Norton Anti-virus and it didn't seem to speed it up any. But I left it disabled after I rebooted the Time Capsule and had a successful incremental backup, so I'm not sure yet if Norton is a factor.

  • HT1175 I have OSX Lion 10.7.5 and the backup in time machine is extremely slow

    I have OSX 10.7.5 installed on my MacBook Pro and the backup to time machine is extemely slow.  Time Machine indicates 4 days or more.  Why?

    Did you happen to update early in the piece.. there is a supplement.

  • I'm running OS X 10.6.8-Why is Time Machine all of a sudden backing up 225GB of data after 2 years of perfect service? I have not added, deleted, or upgraded anything, Help!

    I'm running OS X 10.6.8-Why is Time Machine all of a sudden backing up 250GB of data after 2 years of perfect service? I have not added, deleted, or upgraded anything.

    USB 3.0 drives work on USB 2.0 but you do get 2.0 speed. They are cheaper because they are popular PC drives.  If you get a new computer you'll get the bump to 3.0 speed.
    I like the Seagate USB 3.0 Backup plus drives. They come formatted for PC but easy to format in Disk Utility.  Seagate Backup Plus Right now the 1T is more than the 2 & 3T drives
    This Western Digital drive has good reviews: WD My Book Hard Drive for Mac 2 TB $99.
    Locally, Best Buy seems to have the best prices.
    USB 3.0 is 10x faster than USB 2.0
    Thunderbolt is 12 times faster than FireWire 800 and up to 20 times faster than USB 2.0.
    Format new drives with Apple's Disk Utility rather than the software that come with the drive.
    My plan was to rid a lot of the stuff I have on my computer (to a hard drive) anyhow once it had backed up.
    I wound't necessarily backup those files to Time Machine. I would copy to the external drive then delete from computer. Only backup to Time Machine the data you would want to restore to your Mac if there was a problem. The backup will go much faster this way. Time Machine backup is slower than just copying data in my experience.

  • Time machine is very slow....

    After upgrading to ML, time machine seems very slow. I usually make back up once a week. First back up took nearly a day, but completed successfully.

  • Why is Time machine backup not working after Mavericks upgrade?

    Why is Time machine backup not working after Mavericks upgrade?

    I had the same problem due to the Fire Wire port.  Apple tested it told me it is OK!, I tried a new cable, and have tested both ports on my back up device.  I find it strange that as soon as I installed Mavericks.  The drive does work using USB.  It could be a coincidence, I don't absolutely know at this point, my back up drive ports could stop working, but I doubt it!

  • Why does Time Machine Hang OSX when a USB drive does not respond?

    I use USB drives to store photo data. When I back up the drives using Time Machine to a Time Capsule, If I have added a large amount of data to the USB drive, the backup will consistently fail with the drive hung. I can see the drive in finder, but I cannot see the directory structure. Often OSX hangs too and I cannot even get to finder, just the whirling colored wheel. Sometimes the system has entered sleep mode and it will not wake up. I if I am using the monitor, I can open the MAC Book Pro cover and the screen there shows alternately, a blue screen and the screen wallpaper, flipping back and forth but otherwise unresponsive. If I turn the USB drive off the OS recovers and Time Machine completes, usually indicating a backup failure (but not always). The drive is always very hot under these circumstances, indicating that the system is issuing repetitive operations to the drive. I should emphasize that I am not writing to the USB drives during backup, Time Machine is just reading the drive. So several questions:
    1) How in the world can a non system drive hang the Operating System? This is a big no-no for a supposedly multi-tasking Operating System.
    2) I use Aperture 2.1 to store data on the USB drives with no problems (at least so far). Why would Time Machine drive the USB drive so hard that it fails? I had the same problem using a USB drive with iTunes. It completely fried the drive by writing to it too intensively during one of the frequent software updates. Is there no throttle mechanism in OSX that limits the disc activity so that the throttle mechanism is not the failure of the drive itself?
    3) Does Apple have a list of USB drives that it has validated to be able to work with it's system reliably?

    Are the USB drives powered from the computer or do they have their own power supplies.
    There is a limit to how much power can be drawn from each USB port and also a total limit. If you exceed this, unexpected things can happen.

  • Suddenly, time machine is very slow. Used to take up a minute and now more than half an hour. Does anybody know how this can happen? Indexing the back-up disk is off, but Timde Machine keeps on indexing!

  • Why is Time machine saying backup disk disconnected? Using MBP 17" Lion 10.7

    Why is Time machine saying backup disk disconnected? Using MBP 17" Lion 10.7

    Do you have an external drive connected?
    If you do has it gone into sleep mode? There is a setting in the OS to put drives to sleep if they aren't being used. Energy Saver "Put the hard disk to sleep when possible".
    Also most external drives have a built in sleep function that if they aren't being accessed for a period of time they go to sleep by themselves.
