Why am I unable to connect to my airport whenever I put my computer to sleep while the time machine is backing up?
Ever since I installed Lion (version 10.7), I am unable to reconnected to my Time Capsule and get on the internet after I put my computer to sleep and then wake it back up. This doesn't happen all the time -- just when I put my computer to sleep when Time Machine is backing up. If I put my computer to sleep when it's not backing up, it's fine. If it is backing up though, when I wake my computer up again, it is unable to reconnect to the Time Capsule to allow me to use the internet. I have to wake the machine up, click on "Stop Backing Up", wait 30-60 seconds, click "Turn Wi-fi off", wait another 30 seconds, turn it back on and then I am fine. If I just turn wifi off and on without stopping the backup, it doesn't work and I am still unable to connect to the internet. I currently have 10.7.1 but it still has the same bug. 10.6.x did not have this bug. Other than "don't put your computer to sleep when Time Machine is backing up," any suggestions? Any help would be greatly appreciated!
In this case, that hint may help.
According to Apple support, some configuration files may get damaged or corrupt by time, after updates or upgrades and should get deleted ocasionally.
OK ... switch off wifi on the machine.
Then go on and delete the files mentioned below.
You will find the files on your system drive (not your home folder) as follow:
/library/preferences/com.apple.preferences.accounts.plist
/library/preferences/com.apple.preferences.sharing.plist
/library/preferences/SstemConfiguration/preferences.plist
/library/preferences/SstemConfiguration/com.apple.airport.preferences.plist
If there are files in this folders with the same name but additional .orig at the end, delete them too.
It is possible that not all files are on your system. That will be ok.
The files will get newly created by system on reboot.
For that reboot the machine.
Join your wireless again.
If you are using Lion, the Library is hidden. You have to use (menu bar) "go to" -> "go to folder" on finder to access them.
If the problem (unlikely) persists, report back here.

Why am I unable to connect to the internet? I am next to my main computer which has no problems.
Try the iPad forum, then:
https://discussions.apple.com/community/ipad/using_ipad
You'll need to include full details, including the model of iPad, the version of iOS, the exact nature and symptoms of the problem, and what if anything you've tried for correcting the problem.

Many things could cause this, for example, the email server is down or cannot be reached due to an Internet problem.

I have moved to rural Texas USA. Only ISP is Exede, a satellite service. I connect with a time machine and an Airport Express. Daily service gets dropped and requires disconnecting and reconnecting the time machine to the satellite box. The dealer is working the problem without success. He is not very familiar with Apple products. Any solutions?
You are going to need to do a few things. And there might not be a simple resolution at all.
I would ring the ISP again and ask if they support any routers.. because in the end, replacing the router might cost you $100 but save a lot of pain. You can keep the extreme for wireless connections to those devices that work ok with it.
I would also note, the issue might not be extreme but Mountain Lion.
Do a search .. many people have experienced issues with the wifi refusing to join when it wakes. I have experienced it myself. There was no problem with the wireless.. it was some sleep issue in the laptop.
But one thing I would do, on the last screen shot you gave me..
Where the ip range is 10.0
Please change that to 192.168
Because of the private addressing used by the ISP.. you will run into issues with routing.
When you change the value.. you will need to then reboot everything.. and everything will change to 192.168.1.x addressing. This is important.
Secondly, change wireless names to all meet the lowest common denominator.. ie SMB protocol.
So names that are short, no spaces and pure alphanumeric.
I recommend you change all names to that spec.
C9 here gives some more info for why this is important, although the specific issue is different.

Thirdly I want you to install 5.6 utility unless you are running Snow Leopard or Lion still this is a bit tricky. But only 5.6 can access the Extreme's log. Also you can see the actual wireless connection graphs.
All of this was chucked away with v6.
How to load 5.6 into ML.
1. Download 5.6 for Lion.
http://support.apple.com/kb/DL1482
Click to open the dmg but do not attempt to install the pkg.. it won't work anyway.
2. Download and install unpkg.
http://www.timdoug.com/unpkg/
Run unpkg on the desktop.. it is very simple.. drag the AirPortUtility56.pkg file over to unpkg.. and it will create a new directory of the same name on the desktop.. drill down.. applications utilities .. there lo and behold is Airport utility 5.6 .. drag it to your main utilities directory or just run it from current location.
You cannot uninstall 6.1 (now 6.2 if you updated) so don't try.. and you cannot or should not run them both at the same time.. so just ignore the toyland version.. the plastic hammer.. and start using 5.6.. a real tool.
For screen shots see this post.

I have changed the name and password for my Time Capsule and now the Time Machine will not connect
Mac Book Pro
1TB Time Capsule.
Yesterday I changed the name and password on my time capsule and also the name and password of the wifi network as I was having problems with the speed of the internet when using Safari on any of my devices (1 Macbook pro, 1 macbook air, 27" iMac, iPhone and iPad) all other internet services were working fine (email etc.) This seems to have solved the problem.
However, since then, my time machine back ups will not reconnect and there is no option for me to reconnect to the existing back up for my macbook pro.
When I enter the time machine preferences it shows as below that there are no back ups.
Then, when I go to select a drive to use which should be the MacBook under the Backup disks the only option is for me to Remove Disk...
So, my question is, how do I reconnect to an existing Time Machine back up for my MacBook pro as I really do not want to erase and start all over again.
Warning - In my naiveté, I did click on the MacBook in 'Available Disks' but I got the impression that it was about to start a whole new back up and not work with the existing one.
(And does anybody have an inkling as to why there was a problem with Safari on all my devices? I downloaded Google Chrome and that worked fine).Simply reset the Time Machine.
See A4 here http://pondini.org/TM/Troubleshooting.html
You can then mount the TC disk in finder after you reboot the computer.
You should be able to reselect the TC disk and then it will say it is going to start a new backup.
Ignore this.. when the TM actually loads the TC disk it will discover the existing backup and continue the backup.. but it will give no hint until it actually starts that it won't start a new backup. you just have to believe it won't.. and mostly it works..
Please also install the widget A1 so you have some idea what TM is doing. -
i am using for first time the time machine and an external hard drive because I want to erase my macbook and start from zero files. Am i keeping my files in the portable hard disk when I will connect it again with the macbook or the time machine will erase all?
I would like to know if after I erase all my data, empy hard drive inside the macbook, the time machine will erase all my files that I have saved in my "WD "My passport" external hard driveWelcome to Apple Support Communities
Time Machine has to erase the external disk in order to make backups. Before setting Time Machine up, copy the files of your external disk to the hard disk of the Mac in order not to lose them, and then, set up Time Machine. The first backup will start automatically.
If you want more information about Time Machine, read the Pondini's site > http://pondini.org -
I have suddenly become unable to access photo library (iPhoto vers 9.5) on my external hard drive. Also time machine isnt backing up to same external hard drive (LaCie). The drive does show up on the desk top, but when i open iPhoto the library isnt listed, so I cant option click.
First, one should not try to run an iPhoto library from the same volume/drive that is being used by Time Machine for backups. TM will continue to fill up the drive thus squeezing out iPhoto from being able to be opened and used. Also that doesn't allow you to let TM backup your library as it does with other files on your boot drive.
If you partition the EHD into two separate partitions you can run the library from it but that won't let TM backup the library which is important.
Are you able to see the library on the EHD via the Finder? If so copy it back to your boot drive and open it there. You may have to do some fixing on it.
Solution is to either run the library from the boot drive or get a second EHD to run the library from and let TM back it up along with your boot drive.

Will Time machine automatically back up an external hard drive connected to my iMac?
I have a Lacie external firewire hard disc connected to my iMac, containing Aperture library. Will Time Machine automatically back up both the external disc and the iMac HD?
AdrianWill Time Machine automatically back up both the external disc and the iMac HD
Open System Preferences (gear icon on the dock) and open Time Machine
Click on Options
Do you see the name of your Lacie drive in the "Exclusions List"? If yes, the Lacie drive is currently not set to backup with your Mac.
Click on your Lacie drive to highlght it, then click the - (minus) button at the bottom of the list to remove the drive from the "Exclusions" list.
Now, Time Machine will backup both your Mac and the Lacie drive on the next pass. Allow plenty of time for this backup, avoiding wireless if possible, and connecting the Mac directly to one of the Ethernet ports on the Time Capsule. Ethernet will go 3-5 faster than wireless, on average. -
Can I use time machine to back up via a hard drive connected by USB to a HomeHub router?
Can I use time machine to back up via a hard drive connected by USB to a BT HomeHub router? Is there a better way to back up and store files than via the USB port on my new MacBook Pro? I'd like storage to be accessible from my earlier version MacBook too.
I think you want to make backups without connecting a hard disk via USB. In other words, you want to have the data storage be shared in your home wirelessly.
If this is the case, I recommend using a Time Capsule.
Time Capsule works great with Time Machine. You can set up all your devices to automatically make backups on the Time Capsule wirelessly and effortlessly. -
I am trying to use Time Machine to back-up to an external hard drive and I get the following message.Unable to complete backup. An error occurred while creating the backup folder. Does anyone know what I should do?
Hello Drake, I suspect one or more of the Drives needs repairing, but...
Have you looked through Pondini's extensive TM help site?

I am wondering why the Time Machine gets stuck during the Cleaning Up phase of Backing Up???
Hallo Kieth ,
I am not quite ready to restore the full iphoto library , as I have days of work re - imputting titles,descriptions and enhancement . I hope that your suggestion works , as I use my Macbook basically to work with digital photography. Through time , I will need to delete my library to recover more disc space and I would hate to have to spend more time re - imputting titles and descriptions all over again .
Thanks for your interest and advice.

I just bought an iMac now running OSX 10.8.4. I have a G5 running OXS 10.5.8 - External HD connected to the G5 been using Time Machine to back up. Need to get my files, photos etc. but not applications etc. onto the iMac. How do I do it?

Not those whole folders, but their contents, maybe.
If the user account now on the Mac has read rights to the user account(s) on the backups, yes. If not, you may have to do some finagling.
Try the Browse Other Backup Disks option, per Time Machine - Frequently Asked Question #17. If you find an account that can open those folders, restore what you want to an alternate location (#16 in the FAQ).
If not try creating one or more accounts temporarily. -
Wifi issue - Sleep/resume when Time Machine is active results in lost connection
I was having issues with wifi connectivity to my Time Capsule since upgrading to Lion. I've narrowed down the scenario to having my Macbook go to sleep when Time Machine is backing up. When I later resume, my wifi connection is dead and I have to disable/reenable to connect to the Time Capsule.
Running early 2011 Macbook Pro 15" with OS X Lion.I am having the same problem.
The only short term fix I have found is to Force Quit Finder (press Alt + Cmd + Esc, or go to menu bar Apple Logo -> Force Quit then select Finder and click Force Quit). Finder then quickly restarts and I am able to reconnect to my WiFi.
I was hoping the latest update, OS X 10.7.1, would have resolved this but unfortuately it has not. I hope Apple can resolve this issue quickly.
Dan
p.s. I can't confirm that this problem only occurs when my mac goes to sleep during a Time Machine back up, simply becuase I have not checked for this. I will try and check and report back.
