MacAir11" bought in July 2011. On erasing data now cannot connect to Internet

i erased the data from my MacAir11" (bought in 2011) as I was giving it to my daughter. Result was a blank screen with only the apple logo! No internet connection So could not reload software. Fixit suggested I connect my router by Ethernet connection but AirBook does not have a slot for that. On further research found that due to my router WEP no internet recovery is possible! Please help!

Greetings gmonica,
It seems you cannot successfully reinstall OS X, or connect to Wi-Fi. Based on the information you have provided, it appears your MacBook Air needs to be serviced. The following link should help you get started with the process and has links with additional information on topics such as warranty and service pricing, battery replacement, and express replacement service.

I have bought my MacBook since July 2011. It has now become frustratingly slow. What shall i do?

I have bought my MacBook Pro since July 2011. It has now become frustratingly slow. I tried using the HELP key but did not seem to find any helpful information. What shall i do?

Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with visits to:     OS X Maintenance - MacAttorney;
                                  The X Lab: The X-FAQs;
                                  The Safe Mac » Mac Performance Guide;
                                  The Safe Mac » The myth of the dirty Mac;
                                  Mac maintenance Quick Assist.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
Repair the Hard Drive - Lion/Mountain Lion/Mavericks
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the Utilites Menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD disk icon and click on the arrow button below.
When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Restart your computer normally and see if this has helped any. Next do some maintenance:
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
Note: Alsoft ships DW on a bootable DVD that will startup Macs running Snow Leopard or earlier. It cannot start Macs that came with Lion or later pre-installed, however, DW will work on those models.
Suggestions for OS X Maintenance
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or later and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive.
Helpful Links Regarding Malware Protection
An excellent link to read is Tom Reed's Mac Malware Guide.
Also, visit The XLab FAQs and read Detecting and avoiding malware and spyware.
See these Apple articles:
Mac OS X Snow Leopard and malware detection
OS X Lion- Protect your Mac from malware
OS X Mountain Lion- Protect your Mac from malware
About file quarantine in OS X
If you require anti-virus protection I recommend using VirusBarrier Express 1.1.6 or Dr.Web Light both from the App Store. They're both free, and since they're from the App Store, they won't destabilize the system. (Thank you to Thomas Reed for these recommendations.)
Troubleshooting Applications
I recommend downloading a utility such as TinkerTool System, OnyX, Mavericks Cache Cleaner, or Cocktail that you can use for removing old log files and archives, clearing caches, etc. Corrupted cache, log, or temporary files can cause application or OS X crashes as well as kernel panics.
If you have Snow Leopard or Leopard, then for similar repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. Applejack does not work with Lion and later.
Basic Backup
For some people Time Machine will be more than adequate. Time Machine is part of OS X. There are two components:
1. A Time Machine preferences panel as part of System Preferences;
2. A Time Machine application located in the Applications folder. It is
    used to manage backups and to restore backups. Time Machine
    requires a backup drive that is at least twice the capacity of the
    drive being backed up.
Alternatively, get an external drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Carbon Copy Cloner
2. Get Backup
3. Deja Vu
4. SuperDuper!
5. Synk Pro
6. Tri-Backup
Visit The XLab FAQs and read the FAQ on backup and restore. Also read How to Back Up and Restore Your Files. For help with using Time Machine visit Pondini's Time Machine FAQ for help with all things Time Machine.
Referenced software can be found at MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Pre-Mavericks
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Mavericks and later
Open Activity Monitor in the Utilities folder. Select All Processes from the View menu. Click on the CPU tab in the toolbar. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time (>=70,) then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

Data service cannot connect to mover

Hello,
I have an installation of OSB that worked ok until last week.
From last week, the following message started appear, and I need your help to understand if this is a physical error or it is a OSB problem:
Error: data service cannot connect to mover - error connecting to another NDMP server (NDMP client)
Below a full example (it is a piece of osb job log):

Thank you in advance.

Can you include an "obtool lsh -l" please? You may also want to check that you can do an "obtool pingh" to the client and media servers that are being used. Maybe a service isn't accessible.
Please confirm you are using OSB 10.3.0.3.0 from "obtar -V"
You should also not really be writing your RMAN jobs to the OSB Catalog Media Family. You should instead use its own or the RMAN-DEFAULT one.
Thanks

I bought creative suites over 3 years, but now cannot update and registered in my account, the error massage are:This serial number has already been registered. Products can only be registered once.

i bought creative suites over 3 years, but now cannot update and registered in my account, the error massage are:This serial number has already been registered. Products can only be registered once.

The message is correct. You can only register a product once... there is no need to register again after you do it the first time. You can re-install and activate with the serial number, but there is no need to re-register.

After erasing all data & settings, cannot connect to wi-fi

To try to make a long story, short, I was having trouble connecting to my home network with my iPod. It was previously owned, so I figured since I'd be losing everything with the first sync, I decided to perform a full erase of data and settings. After some initial trouble with error messages, when I first tried to connect to iTunes, the iPod is finally working...but I still cannot connect to my home network. I even went as far as to open my router control panel and reset the password, then set up a new connection on the iPod, even though my home network is showing in the list, wi-fi is turned on and ask to join is turned on. By default, my router security is set to WPA2, but even after I turned security off, it still won't let me join. I have other devices connected, and working fine, even after the password change. I'm truly stumped, here....

Did you make sure your router/modem are set up and configured with the settings specified in the second article I linked above.
Have you tried shortening the password/key to the network?
After you turned of all the encryption settings, did you reset the network settings again then try to reconnect?
It would really help to try and connect this device to another working Wi-Fi network to help determine if it's an iPod issue or a router/modem issue.
Is the router/modem using the 2.4 or 5 GHz band? Or both?
What is the brand and model of your router/modem?

9300 Curve wifi problem - cannot connect to internet using only wifi once data turned off

I've got a 9300 Curve with a data plan from Rogers. I want to use my wifi in hotspots when I go overseas without using my data. I have no problems connecting to wifi networks. Once I turn off my data services, my connections to the wifi network show that the signal is still just as strong, but I can't use my browser, facebook, bbm, etc. - message is "unable to connect to internet" when I try and access my browser. This problem occurs whether I'm using a public hotspot or my home router. I used to be able to access wifi without using data from Rogers on my older Curve (can't remember the model), so I don't think it has anything to do with my plan.
Any suggestions/advice would be much appreciated!

Thanks for the reply!
Did you mean "leave data ON and turn off data roaming"? But that would just turn off my data while I'm roaming, and while I'm not roaming, it'll still access through data and not through wifi like I would prefer. That's what I understand, but pls correct me if I'm wrong! I guess I meant to also mention that whether I'm in my home zone or overseas, I still can't use my browser, bbm, etc through wifi only, with data turned off...it just says there's no connection to the server/internet, even though it shows that I'm connected to a wifi network.

Cannot connect to internet when both wifi & cellular data are activated

I have setup a wifi network in my office to allow all my Apple devices to wirelessly communicate with each other. I purposely setup the wifi hub without Internet access: the sole purpose of the hub is to project data from various iPad's and iPhone's onto my Apple TV. This has worked flawlessly.
I receive a strong Verizon signal in my office which allows me to access the web on my wifi+3G iPad2.
Here is the problem: when I'm connected to both the cellular network and the wifi router (that does not have Internet access), I can no longer search the web. My belief is that even though I have a strong Verizon data signal, the iPad purposely switches over to wifi to access data, continuously searching for an Internet connection that isn't there.
Does anyone have a solution to this? Is there a way to override the iPad so it pulls data from the cellular network first, then from wifi? Please note that I do not have the ability to establish an Internet connection through the wifi router--only via the cellular network.
The goal is to be able to surf the web on the iPad using the Verizon network, and project what I'm viewing onto the Apple TV using the wireless hub. I can execute both actions separately, but not simultaneously.

The iPad uses wifi first for connection. If wifi is not available, it switches to cellular. I know of no way to reverse the connection. You'll have to make your connections manually each time. If you want to use cellular first, turn wifi Off.

July 2011 15" macbook pro now freezing temporairly every 10-15 seconds

I'm having an issue with my summer 2011 macbook pro 15".
typing, web browsing etc.. every 10-15 seconds the whole computer freezes for about 5 seconds then repeats. it's really annoying to use this way. it affects all functions.

Hi...
How much free space on the startup disk?
Right or control click the MacintoshHD icon on your Desktop. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure there's a minimum of 15% free disk space.
If there's enough free storage space on the disk, try Starting up in Safe Mode
A Safe Mode boot takes much longer than a normal boot so be patient. Once you see the Desktop, click the Apple menu icon top left in the screen. From the drop down menu click Restart.
If the drive still freezes after booting in Safe Mode, since you are running v10.7.4 Lion, use Lion Recovery to repair the startup disk or reinstall the Mac OS X.

HT5569 Have just bought an i-Pad Wi-Fi Cellular and cannot connect to any network, any ideas ?

Totally new and inexperienced to i-pads but have bought one as I need to travel but keep in touch with various things. Have put sim card in and it's asking me to activate i-Pad and offering networks or use mobile connection. As it's a cellular i-Pad I've tried mobile connection but nothing happens, what am I doing wrong ? There are no instructions in box to help.
If anyone can help I would be grateful.
Thanks in advance.

This is the iPod touch forum. I requested you most be moved to the iPad forum.

I cloud backup warning message cannot be cleared despite pressing ok button. I have not registered with an I cloud to date. now cannot activate any functions or power off. Help!

I cannot delete the I cloud backup message on my I Pad3 despite pressing ok button. I pad now locked and i cannot activate any functions or switch off. I have not signed up to an I cloud account to date. IOS 6 loaded last week.

Hello and welcome to the forums;
Our phone support is open every day Monday through Sunday, although there are different hours of operation for the weekend. If after a webOS Doctor reset you are still experiencing the same problems, I would likely recommend replacement, either in a local store for your carrier or through our technical support department.
There may be additional technical support offered or suggested over the phone, this would need to be done first before a replacement could be issued.
Hope this helps,

Ipad 2 erase all now cannot complete activation

I tried to complete an Erase All on my iPad 2. However, when restarting the iPad cannot complete its activation ... neither stand-alone nor when connected to my MacBook's iTunes account. I am in an endless loop and the activation will not complete. Any thoughts on what I can do?!?

Thank you! So when I sale it my friend should be able to "restore" from his itunes account?
I just needed to make sure al my personal and church business information was off the ipad 1 before I sold it.
Thanks again for the help.

Data modeler cannot connect to non-default sql server instance

I've just started using DM, it installed and loaded fine, I got the jdbc drivers v2.0 from MS so that I can reverse engineer a couple of SQL-Server 2005 DB's.
All worked just fine until I tried to connect to a machine with a named-sql-server instance.
Normal way of doing this for sql-server is to add instance name to end of hostname in the hostname field, like this: "server10\inst01"
but this gives me a cannot-connect-to-server10 error.
I copied database over to a different server that has just a default sql-server instance and it worked fine. (both sql-server2005 and 2000!)
I also tried the older 1.2 jdbc driver from MS against the sql-server 2005 named instance, no luck!
I tried putting the instance name in front of the port number, that didn't work either.
Am I just doing something wrong? or does DM need a special way of specifying the instance name on the sql-server host?

Hello,
you don't need instance name in order to connect. It's only host and port - probably named instance is not listening on default port. It'll be unfortunate if dynamic port assignment is used - but probably that won't be the case.
I hope someone can tell you the port number.

- Have you tried:
-- Resetting your iPod:
Press and hold the On/Off Sleep/Wake button and the Home
button at the same time for at least ten seconds, until the Apple logo appears.
-- Resetting network setting on the iPod: Settings>General>Reset>Reset Network Settings
-- The troubleshooting here:
iPhone and iPod touch: Troubleshooting Wi-Fi networks and connections
-- Restoring your iPod, first from backup and if problem persist restore to factory defaults/new iPod.
- Can you see the networks? If not try:
Unable to use Wi-Fi or Bluetooth with iPhone or iPod touch because there's no address listed for the device
