  • Macbook air can't go to the internet when connected with hard disk

    Hi, so my macbook air can't go to the internet everytime when it is connected with my hard disk. The wifi icon on the top right corner says my macbook is connected to my wifi but my macbook just can't go to the internet. I unplugged my hard disk and I have no problem connecting to the internet right away? I would like to know if there is any solution for this problem.
    Thank you

  • HT4260 I did everything the article suggests. And for my macbook pro it works perfectly. But all the other devices (iphone 5, 4, Macbook Air) can't connect to the network. Anybody any idea's?

    Try resetting your modem. Power it down. Wait a moment, then power it up again. While it resets, do not change what is connected to it.
    In another, though unrelated article, Apple recommends the following:
    If you have configured your Wi-Fi base stations in the past, it may be helpful to do a factory default reset of each Wi-Fi base station that will be part of the wireless extended network before you begin.
    This step really ought not be considered optional for the configuration you propose. If the problem persists after resetting your modem, reset everything else too.

  • Just bought a macbook and can't connect to the internet.   very frustrating

    i can't connect through my wireless router. it reads it but can't connect. my brothers hp laptop connects to it and works. i brought it to work and tried to connect to the router at work but it failed again. but my bro's hp just reads it right away. i need some help please.

    Hi,
    The same happened to me, but here's a fix.
    If it is password encrypted, when you first turn on your macbook, and they give you the internet connection list, Click on advance, and select "This computer does not connect to the internet" Then everything will finish installing.
    Now when you see the wireless symbol on top of your screen (right next to the blue tooth) select Airport ON if it isn't enabled. Then connect to your wireless router, and when it asks for the password, click on the internet password type, and select the "Wireless WEP 12/48 key...or something like that" and it should connect. That is what I did to my macbook and it worked

  • MacBook Air will not connect to the internet

    I am trying to assist my wife with her Macbook air (MbA), it will no longer connect to the "internet". BACKGROUND: I am running Century Link DSL Modem, with a Belkin Wireless router.  I have about 10 different nodes on my home network, PC, Apple and Droid devices.  All of which have no issues with access to the internet.  My wife's MbA however will not access the web, it does however connect to my network and get a DHCP assigned IPv4 Address from my network.  I am able to go to addresses and inside my network and serve up http such as my router's web page.  WHAT I HAVE TRYIED: I have flushed/removed all previously connected wireless networks on the MbA and turned off wireless on the device then shutdown and restarted it and reconnected to my SSID (wireless network) = no joy, didn't work.  I have rebooted all of my network equipment = no joy, didn't work.  I have changed the DNS to an address outside my network = no joy, didn't work.  I don't know alot about Mac/apple product, they seem simple and straight forward, and I have been a cisco routrer/switch jockey for about the last 7 years of my carreer.... this one stumps me.   Any ideas? Firewall configuration, is there a "intranet" only box checked somewhere?
    PS... I may have miss spelled my words, human communication matters, spelling is over rated.

    Power down the router. Unplug the cord from the wall. Wait a while.
    Plug the cord back in. Restart the router.
    Wait until all the lights are lit up properly.

  • MacBook Air freezes when connected to the Internet. (LAN and WiFi)

    I have a MacBook Air A1304 running Mac OS X 10.6.8.
    When it connects to the AirLive Duo router set as Client + AP (bridges the wifi signal from the DSL), it freezes up. 
    Wifi works fine with the iPad.  I tried the wifi and LAN and I get the same results. I don't even have to be surfing, just being connected to the Internet will freezes the whole MBA after about a minute.
    AirLive tested their router with their MacBook for two days but didn't have any problem. I run the latest firmware for the router too.

    Reset the TC to factory and start again.
    Use all SMB type names for wireless and base station.. Not apple type names.. this is more important since Mavericks.
    I also recommend different names for the different bands.
    So for example.
    TC name.. TCgenx (I use whatever the generation number is for the x.. eg TCgen4 or latest one TCgen5)
    WIreless name.. TC24ghz for 2.4ghz
    TC5ghz for 5ghz
    You can also set the channel manually.
    If you still have issues.. start with no security and then if it fails to connect there is something seriously wrong with the laptop. Did you upgrade install Mavericks?? That can lead to driver issues.. I would recommend a clean install.

  • I recently updated my iPod touch to sync through iCloud - now can't connect to the internet through wifi, my macbook air is working as we speak

    I recently updated my iPod touch to sync through iCloud - now can't connect to the internet through wifi, my macbook air is working as we speak. ive tried 'forgetting this network" in settings; tried turning off and on again; and pulling my hair out! The last was equally useless and a little painful!

    Try:
    - Resetting the iPOd. Nothing will be lost
    Reset iPod touch:  Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Pwer off and then back on yur router

  • Macbook air will not connect to the wifi network

    I recently had to replace my wireless network router and now my macbook air will not connect to the network. it worked fine with the old wireless router. Now, i get a "unable to join wi-fi network" message. The network ID (SSID) and password (WPA) are the same as before. I try to manually enter the password, but continue to get the previous message.
    Any help in figuring out how to correct this problem is greatly appreciated.
    Also, I have several PCs in the house that have had zero problems connecting to my wireless with the new router. What am I doing wrong?

    Hi,
    Ever since did the last airport utility update this has been happening.
    I believe the airport utility update is solely a software update. Repair permission and repair disk (boot from your installation disk A) may help.
    Other wise, http://osxdaily.com/2009/12/22/mac-wireless-problems-guide-to-troubleshooting-ai rport-wireless-problems-on-your-mac/ may help, too.

  • My MacBook Air can't get past the gray screen with the apple logo. What's the fix?

    My MacBook Air can't get past the gray screen with the Apple logo, so I can't login. Does anyone know the fix for this?

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.
    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
    a. Boot into Recovery by holding down the key combination command-R at the startup chime, or from a local Time Machine backup volume (option key at startup.) Release the keys when you see a gray screen with a spinning dial. When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in the support article linked below, under “Instructions for backing up to an external hard disk via Disk Utility.”
    How to back up and restore your files
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode by holding down the key combination command-T at the startup chime. Connect the two Macs with a FireWire or Thunderbolt cable. The internal drive of the machine running in target mode will mount as an external drive on the other machine. Copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    How to use and troubleshoot FireWire target disk mode
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Before reconnecting an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
    Step 3
    Boot in safe mode.* The instructions provided by Apple are as follows:
    Shut down your computer, wait 30 seconds, and then hold down the shift key while pressing the power button.
    When you see the gray Apple logo, release the shift key.
    If you are prompted to log in, type your password, and then hold down the shift key again as you click Log in.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    *Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t boot in safe mode. Post for further instructions.
    When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is damaged and the drive is probably malfunctioning. In that case, go to step 5.
    If you can boot and log in now, reboot as usual (i.e., not in safe mode.) If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 4
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 5
    Launch Disk Utility in Recovery mode (see above for instructions.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it produces. Look for the line "Permissions repaired successfully" at the end of the output. Then reboot as usual.
    Step 6
    Boot into Recovery again. When the OS X Utilities screen appears, follow the prompts to reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Note: You need an always-on Ethernet or Wi-Fi connection to the Internet to use Recovery. It won’t work with USB or PPPoE modems, or with proxy servers, or with networks that require a certificate for authentication.
    Step 7
    Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a backup.
    Step 8
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

  • I put the BT WiFi app on my iPad Mini and now I can't connect to the internet.  Please help

    I put the Bt WiFi app on my iPad Mini  and now I can't connect to the internet.  Please Help

    Some things to try first:
    1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
    2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
    3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
    4. Go into your router security settings and change from WEP to WPA with AES.
    5.  Renew IP Address: (especially if you are droping internet connection)
        •    Launch Settings app
        •    Tap on Wi-Fi
        •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
        •    In the window that opens, tap on the Renew Lease button

    Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
    Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
    You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.
