Airport unconnectivity

I have had a Time Capsule for a while now, and I used to have a dsl modem connected to it, I had my HP printer connected to the wireless network with no problems, I had my roommate using the network, all working nicely. But a few months ago the roomie was complaining about not being able to connect, then my imac no longer could connect to the internet, so I connected the modem directly to my iMac with an ethernet cord. Now my printer won't connect to the network. Backups are still happening wirelessly through out all this. It seems like a slow, months-long degeneration of the network. All along I have been trying to reconfigure addresses and restart devices and all the other hoops the dialogue boxes have asked me to jump through.
Oh, and then I get an iPhone and it won't connect with the wifi network. I have tried to set up the Remote app, and there are fleeting moments where the computer and the phone are communicating, but it never lasts for long.
Am I missing some vital point concerning airport configuration or something?

If you have set up the AirPort Extreme again and the amber light is flashing......AirPort Utility will tell you why.
Open AirPort Utility
Click on the AirPort Extreme icon
Look for the setting for Status
Click on the amber dot there
What does the message say?

  • Problem with Airport Connection

    Just bought new AirPort Express to use to extend range of my wireless network.
    I set up system via Airport Utility. At end of set up I get message telling me that the settings for the AirPort Express have been successfully updated and I can close window or wait for the AirPort Express to restart.
    All this time the airport express is flashing amber.
    Then I get message: the settings for Airport successfully updated but problem in rejoining the wireless network or finding the device. You may need to select your network from the W-Fi menu and try again.
    When I go onto the Wi-Fi settings I then have to reset to join existing network. But Airport remains unconnected. I have run through this a few times and exactly the same thing happens.
    Any advice?

    Ok thank you for clarifying that for me.
    Try setting up the extended network again. This time, keep the Express (AX) in the same room as the Time Capsule (TC). Allow both base stations to restart.
    Leave them together until you can verify that the extended network configuration is working. Once verified you can place the AX at the desired location. Note: Placement of the extending base station is critical for overall bandwidth performance of your extended network. Please check out the following AirPort User Tip for details.

  • How do I get the TC on my Airport Extreme to do wireless backups?

    I just want to use the TC for wireless backup.   I've connected it to the Airport with Ethernet; unconnected the EThernet; opened Airport Utility; read the Manual; studied all these posts.  Nada.  It should be simple, I only need the TC to act like an external HD on the network.  Any suggestions??
    Twila Johnson

    Let's go with simple for now and get things working.
    Disconnect the Ethernet cable for now, and power down the TC by pulling the power cord
    Wait a minute
    Hold in the reset button on the back of the TC and keep holding for an additional 8-10 seconds while you simultaneously plug the power cord back in to the TC  (tricky to do...because you almost need 3 hands)
    Release the reset button after the hold period and allow 25-30 seconds for the TC to restart to a slow, blinking amber light
    Connect the Ethernet cable from one of the LAN <-> ports on the AirPort Extreme to the WAN port (circle of dots icon) on the TC
    Open AirPort Utility, select the TC, and click Manual Setup
    Click the Time Capsule tab below the row of icons to assign a name to your Time Capsule, a device password (write that down) and adjust Time Zone settings.
    Click the Wireless tab next to the Time Capsule tab
    Change the setting for Wireless Mode to "Off"
    Click the Internet icon, then click the Internet Connection tab
    Connect Using= Ethernet
    Connection Sharing = Off (Bridge Mode)
    Click Update and allow 25-30 seconds for the TC to restart. You should have a green light.
    Power off the entire network now....all devices.....power down order is not important
    Wait a minute
    Start the modem first and let it run a minute by itself
    Start the AirPort Extreme the same way
    Start the TC the same way
    Start other devices one at a time the same way
    You should be all set

  • Loss Airport Connectivity

    I have been using for months a PowerBook G4 Titanium 400Mhz with an Airport card, connected to a D-Link DI-524 router. This setup has been working without a problem (not very fast but without problems!). Today, without any visible reason, Airport stop recognizing any network. I haven't changed a thing and a MacBook Pro sitting just beside is recognizing two available networks (and using one of them).
    Trying to solve this issue, I already have:
    1. shut down everything (computer, router…) and start again
    2. reset the PRAM
    3. take the Airport card off and insert it again
    4. check if the card slot's connection to the logic board where loose
    5. do the ‘press the antenna’ trick (used for some people to improve range)
    None of these things solved the problem and the PowerBook remains unconnected…
    Any ideas? Thanks.

    My airport started working "erratically" a few weeks ago. It would be fine for a while but then drop the connection and, like tomasgf, it wouldn't even recognise a network let alone connect to it. Then, an hour later or so, it would recognise the network and automatically connect again. And all the time my other computer was connected fine so it wasn't a problem with the router.
    Because it kept coming and going I thought it was probably an antenna problem - most likely the cable being pinched by the display hinge) so I started being very careful to not move the screen at all. (I think on all Ti-Books the antenna goes through the hinge and around the edge of the display.)
    However, it still dropped it and then randomly found it even when I just left the whole thing alone. So I decided to open her up and check that the Airport Card was properly seated and the antenna cable was plugged in. Both looked fine. So I was somewhat stuck.
    Took it to a Genius in the Regents Street store a few days later and, once he'd congratulated me on my 'antique', he couldn't think of anything that would cause the problem off the top of his head. So he opened her up to check things as I had done and concluded all was okay. He also booted up from an external disk and it still wouldn't pick up the network which shows that, for me at least, it isn't a software issue.
    It didn't work at all for a few days and then, about a week ago, it started working and has been perfect since. I've been opening and closing it at will, shifting the screen freely, and it's fine. I've not added any applications let alone updating any software at any point (and even when it started wasn't after any system alterations).
    So, maybe somewhat uselessly, I cannot offer a solution other. Merely wanted to document that this could inexplicably happen. I guess I feel that it is most likely an antenna issue so I sadly expect it to recur. However, the cost and ease of putting a new ethernet card with it's own antenna in the PC card slot will likely lead me to do that rather than opening up the display casing to find the true cause of the problem.

  • How do I fix the airport dropping internet issue? 10.6.8

    Started doing it about a month ago conveniently a year after I got the computer. Seems to be a pretty common problem but I can't find a remedy. None of my hardware has changed since it worked flawlessly about a month ago. Now I have to unconnect and reconnect airport every ten minutes if I want to use the internet. Being an online student you can tell the obvious problems.

  • Yosemite no longer plays music across Airport

    Since the upgrade to Yosemite, Airport+iTunes no longer delevers music reliably to a remote Airport Express.
    The music flow works reasonably well when it works, but then it terminates, and most often stays unconnected until I
    deselect the Airport Express unit in iTunes, and reselect it. Only then will the music flow resume.
    The average duration of the music flow is around 3 minutes, which makes iTunes completely useless.
    Is there a fix for this, other than moving on to a more reliable platform?
    It should be noted, that the Airport network as such has not changed at all, the only real change is the OS upgrade.

    Yosemite has pathetic networking.
    You need to do a lot more for Yosemite to work.. If you upgrade installed.. I would have to say there might be no fix. Especially if this is over wireless.
    Otherwise try the normal stuff.
    Yosemite.. script the mount
    https://discussions.apple.com/thread/6747833
    That was a post from Tesserax I saw.. nothing works for everyone.. because Apple have made it buggy as anything.. I doubt we have got to the bottom bug layer.
    Where you see TC (time capsule) substitute AE in your mind. Ignore the disk info.. as I use the same set of options for everyone.
    A factory reset of the TC is the start.. it is required so you can find it again.
    Factory reset universal
    Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
    N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
    Setup the TC again.
    ie Start from a factory reset. No files are lost on the hard disk doing this.
    Then redo the setup from the computer with Yosemite.
    1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
    eg TCgen5 and TCwifi for basestation and wireless respectively.
    Even better if the issue is more wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round.
    2. Use all passwords that also comply but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
    3. Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking. If the TC is main router it will not be an issue.
    4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
    5. Mount the TC disk in the computer manually.
    In Finder, Go, Connect to server from the top menu,
    Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
    You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
    However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
    6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only.
    There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
    You might need to do some more work on the laptop itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
    Tell us how you go.

  • IMac - Laptop Airport connection?

    Greetings. I have a little issue; I've scoured the Help Boards here for a solution to this problem but mine seems to be a bit different.
    I have an iMac 3.0GHz (2008) on the internet via cable modem (I'm in Japan, if it matters). I also have a laptop (PowerBook G4 with an Airport Card). I want to get the laptop on the internet by connecting it wirelessly to the iMac (which is only across the room, for example).
    The laptop is capable of finding other wi-fi networks (at schools, cafes, etc.), but not one I just made on my iMac (via the Airport drop-down menu icon that looks like a radar cross-section). And yet, the name of the network that I just created IS VISIBLE in the laptop's Airport drop-down menu! But I cannot get the laptop browsers to access any site.
    (Please note that the iMac is running 10.5.5 and the laptop is running 10.3.9.)
    Any ideas?
    Many thanks,
    E.

    Excellent information, E. To answer your first question, the setting changes I mentioned should only be performed on the "host" machine - the one with the wired ethernet connection in your case. It sounds from your description like that should be the iMac desktop.
    On the laptop, change the settings back to the normal state - Security to what you had, Sharing with the Internet Sharing OFF.
    Then, on the laptop, make sure the Airport is on. Pull down the list of networks (by clicking on the Airport icon in the menu bar - though you probably knew that already!) and locate the name you gave to the iMac. Select that name, and the laptop should connect just fine.
    Here are some additional details for you (with @ signs as bullets!)...
    @ DNS does stand for Domain Name Server (or sometimes System). DNS translates web names into their associated IP addresses. For example, if you were to "ping" a charity I know at www.frrn.org, you would probably get the IP address 209.67.63.95 A DNS server stores the relationship between an IP address and its common name, pointing you to the real location when you type in that common name. This service is usually something your ISP provides. It is for web access, so really doesn't apply to your ability to network one computer to another. Now, if you weren't seeing web pages once you were connected...
    @ For your connection sharing, you have one machine, say, that is connected to the network, either by wired Ethernet or via Airport. It can be either, but if I'm understanding your situation correctly, yours is an iMac that's connected to the Internet by wired ethernet cable. We'll call that iMac the "host".
    @ You have one machine that is not connected to the Internet. You want to connect it either by Airport or by wired ethernet. In your case, it looks like you want to connect the laptop by Airport. We'll call this laptop the "client".
    @ Your "host" has to share its connection. Your "client" simply has to receive the connection - no sharing is required on the client's part.
    @ Your host can't share out its connection in the same way it's connected into the Internet. In other words, if your host (the iMac) is receiving Internet through an ethernet cable, it will have to share that connection out through its Airport.
    @ When you set up the sharing on your host, then, the "Share your connection from:" relates to how the host is connected to the Internet. (It's the "in" connection for the host.) So, if your host (the iMac) is connected by an ethernet cable, then Ethernet is what you would choose from the dropdown. If, on the other hand, your host were connected to the Internet by its Airport, then you would choose Airport from this dropdown.
    @ On the host, "To computer using:" is how you want the unconnected computer(s) to connect to the Internet. (It's the "out" connection for the host.) Since you want the laptop to connect with its Airport, you would select Airport here. If you were wanting to connect an ethernet cable between your iMac and the laptop, you would instead choose Ethernet here.
    @ Once you have the host set up, the client, then, just connects as normal for that method (using the Airport dropdown, for example).
    In summary, you only set up the host for sharing. You have to set the "Share your connections from:" and the "To computers using:" opposite. Your iMac can't be connected to the Internet through Ethernet and then expect that other computers would be able to connect through that same method. (You have to have separate "in" and "out" connections - one Ethernet, the other Airport.)
    I hope all these details aren't confusing you more. It's really easy - just set up the iMac, then connect the laptop as though you were at a wi-fi hotspot, looking for the name you gave to the iMac as the hotspot name.

  • Strange AirPort icon

    Hi all,
    I was using my 15" MacBook Pro with Wireshark to monitor some wireless traffic on my network. I had my AirPort on but not connected to any network (I was using Wireshark in promiscuous mode) when I saw my AirPort status icon in the menu bar change from the unconnected symbol to the strange symbol shown in the screenshot. Any ideas on what it means?
    It was there for a few seconds and disappeared. It appears to appear and disappear randomly, hard to tell whether it disappears when I stop the monitoring.
    I took a look at this knowledge base article (HT3821) but it's for 10.6, so it's a bit out of date.

  • Loosing and slow connection with Airport Extreme

    Hi. Before I start, I hope there are some who suffer the same problem as me.
    First of all, I have a problem with my MacBook and Airport Extreme. The Network I created with Airport is getting really slow or unconnected with my MacBook. So I tried to reset both the modem and Airport. Actually, it kinda works, however this problem occurs later.
    First time I thought it was the problem with uTorrent that I didn't use uTorrent anymore but it still has a problem.
    Because of this **** problem, I have to reset my modem and Airport Extreme several times a day and it really stressed me out. Embarrasingly, I don't even know what the problem is. is ti the problem with My macBook? AirPort Extreme? Modem? No idea..
    I need a help...
    P.S. Modem seems working fine since the ethernet is working fine. maybe problem of Airport or MacBook. I think I should go to the Genius Bar but I am afraid that 'Genius' is going to just check once and say 'It has no problem.'

    I too am having very slow connection speed issues with two of my white macbooks, both running 10.6.2, same airport extreme wireless adapter (built in). The strange thing is, these two macbooks came in a macbook 5-pack, and the 3 other laptops all have excellent speed. Nothing different has been done with these 2 laptops - all were updated (albeit the 2 were much slower to download the update), with nothing new installed otherwise...
    There were some Macbooks that had an issue with the screws holding their internal AirPort cards in place loosening, resulting in noise and lower signal levels from the antennas.
    You may want to try taking one of the affected Macbooks to a local Apple Store and see if you experience the same issues on their in-store network.

  • Extremely unstable Airport network

    [Dutch so sorry for my English]
    My Airport network (1 extreme (latest), 1 express (1st gen)) is extremely unstable (especially AirPort Extreme), my iPad and iPhone are being unconnected every 2 minutes or so.
    My iMac is connected over ethernet and wifi, my speeds:
    Ethernet: 59Mbps down; 5,5Mbps up.
    Wifi: 9Mbps down; 5,5Mbps up. (distance between Airport Extreme and iMac is one wall and 5 meters.)
    Ridiculous right?!
    Especially the problem my devices are trown of the wifi network every couple minutes is REALLY frustrating. Didn't have the problem until like half a year ago.
    Tried a lot, the channel stuff (I don't have many networks near my place, so I have few interference), all the basic solutions for the basic problems. None have worked so far.
    Hope you can help me, this is kinda my last shot.

  • Airport can no longer read or write the configuration of Time Capsule

    I have a MacBook Pro running OSX 10.8.3 and maintained with all available patches. I have also a Time Capsule with version 7.6.3 of the firmware. I use AirPort 6.2. So everything seems to be updated with the latest versions.
    This has really been a good setup for nearly a year now, but earlier this month Time Machine suddenly stopped to work and could no longer do backups to the Time Capsule. I have tried to factory reset the Time Capsule several times, but I still get problems when writing the configuration to the Time Capsule. I get an error message saying "An error occurred while updating the configuration".
    Airport is furthermore not able to detect the Time Capsule correctly anymore, so I have to configure it by entering the IP address. But after setting up WLAN, disks, etc. and enhanching the security, I just receive the error message when I try to write the config. The Internet connection works perfectly anyway, both via cable and wireless.
    Anyone got any tips?

    Do the setup by ethernet in full isolation from the network.
    Start from a full factory reset.
    I would recommend you take the firmware back to 7.6.1 or even earlier if the TC is older than 12months. 7.5.2 was very reliable. All these bugs started with 7.6 and the change to Lion.
    I would also recommend installing 5.6 utility.
    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.

  • How do I use my airport extreme with my FIOS router?

    How do I use my AirPort Extreme base station with my FIOS Router to extend my network?  I have hard disks connected to my AirPort Extreme and would lik to access them.

    Probably can't answer all your questions - but.... I use a Linksys (wired and wireless) router as my primary entry point for FIOS. I use a Time Capsule and an Airport Express as a common wireless connection. So I have two visibile wireless networks and use them both depending on where I am in the house. Both the TC and AEx can be seen either wirelessly or wired from the entire network. Note - the Linksys provides all the DHCP - you set the apple routers as "bridge mode."

  • Forgot password to access my Airport Time Capsule, can't restore Time Machine backup

    It is stupid, I know, but after the first time I setup Time Machine in my Airport Time Capsule (6 months ago) i never had to use the password because it stayed stored in my Keychain.
    Anyway, couple days ago I had to format the hard drive of my MacBook Pro and I did it thinking that I had a complete data backup stored in my Airport Time Capsule (encrypted data). It was late when I realized that I did not have the password written/stored anywhere. Nothing to do about it, just move on and start all over again.
    I need to clean up my Airport Time Capsule and set it to factory default. I already accepted that I will lose all my data and it is okay. So far all I found was how to reset the wifi user/password but nothing about deleting stored data or reset to factory default without having the encrypted password. Can you please help me? Thanks in advance!  

    The encrypted data is not related to the Time Capsule.. that is purely Time Machine.
    Very sorry for you.. it is one big danger when you encrypt.
    Reset to factory.
    Factory reset universal
    Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
    N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
    Wipe the hard disk. Open the airport utility go to the disk tab. Click on erase disk.
    Select just quick erase.. it just deletes the file table and is not secure but fine for your purposes.

  • New Airport Extreme restarts/disconnects/boots all devices if specific MacBook joins wirelessly...?

    Preface:
    This is my second new AEBS in two weeks. They've both had this issue (which seems unique from the other disconnect postings I've found), so it's not AEBS hardware. I've also had a perfectly functioning Airport Express in the exact same configuration (sans dual-band of course) for the last two years, so interference and the like (for which I did test and troubleshoot) also seems unlikely. I have a 2008 Macbook, a mid 2009 Macbook Pro, a Windows 7 PC, an iPhone 4, and iPhone 4s, and an iPad on the network.
    Issue:
    After setting up my AEBS, I kept getting knocked off at random, frequent intervals. It would disappear from all my devices simultaneously--no network connections and nothing showing in Airport Utility. I tweaked every setting imaginable five times over. No luck. Looked into networks around me and fiddled with channels etc. No luck. At first, I would have to go unplug and replug the AEBS to get it to show back up. Eventually I managed to get it to where it would just "reset" more or less and come back on in about 30-45 seconds. The light on the router will blink green once, and then two seconds later go solid amber for about 10-15 seconds, and then blink amber for another 10 or so. Then it's back like nothing happened.
    I think that I finally narrowed it down today to what is triggering it more or less. I noticed it was fine with everything connected WITHOUT any security. When I added the WPA2 security back on, it was doing it soon after the older Macbook connected, right after "Installed unicast CCMP key for supplicant 3c:d0:f8:8e:31:b5". I could connect the Macbook through ethernet and be fine. If it did connect without the issue, it would do it soon after when the router would run that "Installed unicast CCMP" process again in a mere matter of minutes.
    I decided that maybe having old OSX Leopard wasn't working well, so I finally upgraded it to Snow Leopard to see if maybe it would help. No luck. Exact same issue. I disabled Airport on it, and since then I'm going on 5 hours of no issues, but why is this computer causing the AEBS to freak out when it worked 100% with my Airport Express for years???

    Hi,
    I have roughly the same issue.  I have a new 5th Generation (I had a 4th Generation that seemed to do the same thing) that will reboot for no apparant reason.  I have a 1st Generation Time Capsule as the main wireless access point, then a 2nd generation Extreme extending, and the 5th generation as another extension.  I also have an Express extending to the top floor.  All my other devices work great, but the new 5th generation will just reboot over and over.  Seems to be every 5 - 10 minutes.  I have it setup in the middle of my house, with some devices connected to it via ethernet cable.  I used to have the Express in that location connected to a switch for my devices, and never had any issues.  My log looks similar, basically nothing useful.
