Cannot get connected on MacBook Air to wifi that previously worked; iPad and iPhone OK

MacBook Air cannot connect to wifi that previously worked; can connect iPad and iPhone. All software current

If this is a new MBA, and the router is filtering hardware ethernet addresses for security, you will have to add the new address to the router. You can get your wireless hardware address from the Terminal:
ifconfig en1 | grep ether
In System Preferences > Network, check the advanced panel for your Wi-Fi, and verify that you have checked Remember networks this computer has joined. If you network SSID name is not in the Preferred Networks list, add [ + ] it, and drag it into preferred order.
Verify your password used is the same as on the two IOS devices.

  • TS4002 why doesn't deleted mail on my MacBook Air show as deleted on my iPad and iPhone

    I thought that when I deleted mail on my MacBook Air, it would be deleted automatically on my iPad and iPhone. However; this does not happen, and is annoying having to delete from each individual device. How can I rectify this problem please?

    10.6.8 (Snow Leopard) does not support iCloud, are you actually on that or have you upgraded?
    Are you using a .me or .mac address, if not what are you using?

  • My macbook pro is connected to internet via my time capsule but my iPad and iPhone won't. it shows wifi connection to the time capsule but when i go on to the internet on the iPad or iPhone, it comes up with network error. can anyone help?

    my macbook pro is connected to internet via my time capsule but my iPad and iPhone won't. it shows wifi connection to the time capsule but when i go on to the internet on the iPad or iPhone, it comes up with network error. can anyone help?

    This can be caused by a number of issues.
    Was everything working and then suddenly stopped??
    Or is this a new clean setup and has never worked.
    Do you have a cable modem which is not a router and the TC setup in bridge? That will cause it. The TC must be in router mode, ie dhcp and nat.
    Check the IP the MBP gets including dns and gateway..
    Then check the ipad/iphone.. post what IP dns and gateway (router in applespeak) they get.

    Hi , just bought a new macbook air. speakers show that they work but can't hear Skype or youtube. Can you help?

    Have you checked that they are selected in System Preferences>Sound>Output tab?
    If that doesn't help, and although I've never had to use it myself, I've read on here occasionally that launching Audio MIDI Setup in the Utilities folder and messing with the settings in there can sometimes sort out audio problems.

    You will need to use an external DVD drive to run the disc installer that came you your machine. You can also do it with another Mac using the Remote Install Max OS X app. Finely, if you have access to another computer, you could burn the install image on a USB thumb drive, boot from that, erase the drive and run the installer.

  • My wife has a new Ipad and Iphone with icloud. We also have a Imac that has not been upgraded yet that is somehow syncing with her ipad and screwing up the apps. Is there anyway to prevent this. Maybe it is thru mobilme?

    I think iCloud isn't coming until this fall and not until iOS 5 is publicly available. Right now there is confusion because all this stuff is still in beta and things are under NDA and may still change.
    I'd just set the 3GS up the same as currently. When iOS 5 is available in the fall (and I don't think Apple has specified beyond "fall"), before you update, there should be any number of guides to setting things up and how it will all work. http://macworld.com is a good place to look for such information.

  • HT1338 cannot connect my MacBook Air to a projector  -does not detect and 2nd monitor. I have a new Mini port to VGA cable made by apple. When I read online I see that many people have the same problem - Is this an Apple defect??????????????????

    I cannot connect my MacBook Air to a projector - It will not detect a 2nd monitor or display. I am using an Apple made Mini Display port to VGA adapter. As I read online I see that many other peple are having the same problem. Is this an Apple defect!!???? If so it just burst the bubble about how great macs are. I never had a problem with that on a PC. I hope I am wrong. What can you tell me?

    Hi There,
    I have had the exact same issue but with a projector.
    The issue lies with Mountian Lion 10.8.2.
    I tried many a combination with no luck to get HDMI working.
    Took my mac into the apple store and came to the conclusion it was the software, so I asked them to install 10.8 onto it (this is destructive so a backup is a must)
    Bought my macbook home and voila, now displaying through my projector.
    There is a small graphics update after 10.8.1 which seems to be the cause.
    Hope this helps.
    Thanks.

  • HT1277 I cannot send email from my mac but I can from my iPad and iphone

    Hi Guys,
    Suddenly I cannot send email from my Mac.  I can however receive emails.
    I can send emails with the same settings from my iPad and iPhone.
    Please help!!

    Your settings for the SMTP server — host name, port number, SSL/TLS or not, or login credentials — are likely incorrect.  Use the Connection Doctor tool (Mail.app > Window > Connection Doctor) to check what's going on with the connections (and to get some diagnostic messages), then review the diagnostics and the current settings with the requirements established for your particular mail provider.

  • Trying to set up my brand new MacBook Pro and it does not connect with the wifi network I have selected for this purpose. Nothing wrong with the wifi as both my iPad and iPhone are happily connected. Suggestions for connecting to the wifi network accepted

    Setting up my brand new MacBook Pro and it will not connect to the wifi network. Nothing wrong with the network which is happily working for my iPhone and iPad! Suggestions accepted for making this connection.

    Fixing this is a two step process:
    1) System preferences > WiFi/Airport ...
    ... check [√] Ask to join new networks
    "Known networks will be joined automatically.
    If no known networks are available, you will
    be asked before joining a new network."
    2) Remove unwanted networks from the list of "known" networks under
    System preferences > WiFi/Airport > (Advanced) > | Airport/WiFi pane ...
    Close the window and save changes. If no joy, do a restart to ensure you are playing under the new rules.

  • Still: Macbook Air 2013 Wifi Issues On Wake-Up (And Partial Solution)

    I just got my new MBA 13" Mid 2013 last week (updated to Mavericks), and have been having issues with the wifi for a couple days now. Specifically, when I wake my MBA in the morning, it will have disconnected from my home wifi and will not reconnect again. It can see the wifi (and it did ask the WPA2 password after I deleted the network in preferences), but it will not connect due to a "Connection timeout".
    I didn't have these issues with my old MBP 13' Early 2011 (also running Mavericks). Also, this only started after I had fully set up my MBA and replaced my MBP, that is, connected it to the external display, hard drive, etc.
    Now, it turns out what I have to do is disconnect my external hard drive and reconnect to the network. What kind of architecture makes something like this even possible? And it's not just me, https://discussions.apple.com/message/23423481#23423481 had the same problem: needing to remove a USB device in order to be able to reconnect to his wifi.
    This reminds me that with my old MBP, I had an issue where copying large data volumes to external drives via USB would render the wifi connection unusable. So apparently there is something about Macbook architecture that links USB and wifi.
    But why does this only occur after a full night of the MBA sleeping? I guess it would have to drop the wifi for energy saving, which it doesn't do right away whenever it goes to sleep?
    In any way, this is extremely frustrating. What is the deal with USB and wifi in Macbooks? I really hope Apple can fix this via a software solution, but to be honest, I don't trust them to anymore. I guess for them this is "working as intended".
    Cheers
    Nate
    PS: Please, do not post any links to "troubleshooting steps I may find helpful". I do not, because they were not.

    It turns out the MBA doesn't even have to go to sleep for this to happen.
    Today i received a new HDD for my time machine backups, so some data transfer was necessary. I made a 600GB backup from my Mac and an external hdd I use for media files, then i started copying another 500 Gb from one external drive to another (USB to USB).
    Now in the middle of this transfer (which is rather slow to begin with at around 46 MB/s) my wifi connection just went out. My iPhone, iPad and Windows PC can still connect to my router, but the Mac tells me to "move closer" to it.
    It's interesting that my Mac can no longer see any other wifis besides my own, so I guess it's wifi range is somehow impeded by these USB transfers? How does that even work?
    At around 50% the data transfer had come to a complete halt, so I interrupted the process. Two seconds after I had ejected AND unplugged both external drives, the MBA could "see again". All visible wifis were listed again and I could connect without problem.
    Is there anyone with a similar experience? Is this a hardware defect or an architectural problem? Why have I had these USB/wifi-issues on two Macbook models spaced lmost three years apart?

  • HP Deskjet 3055A connecting to Macbook Air without wifi

    Thinking of getting the HP Deskjet 3055A for my son for University.  They use an Ethernet connection rather than wifi and so to connect his Mac to the printer he would presumably use the USB cable instead. Does that sound right and am I right in thinking that the cable he would need is included in the box for the printer?
    This question was solved.

    Hi,
    That is correct.  The printer only supports Wireless or USB and not Wired Ethernet.  The cable does come in the box.
