Hanging AirPort connection?

I have an odd problem. Every now and then, my AirPort connection hangs. It usually occurs immediately after coming out of sleep. I am running 802.11g, not broadcasting SSID, using WPA2 personal. Most of the time, it works great. Every now and then, it will indicate that the network is connected (in Internet Connect), I can run ifconfig and see an appropriate IP address, yet a ping just hangs. Even funnier, it will hang, come back for a minute or two, then hang again.
Anyone seen this? The only way to restore it ends up being rebooting, which is very un-Mac-like.
Thanks.

This sleep issue has been plaguing some mac users for at least the past year.
Not odd, not new.
I'm not sure why it happens.
but if you're familiar with Terminal and ifconfig, try this instead of rebooting:
sudo ifocnfig en1 down
sudo ifconfig en1 up
(en0=ethernet cable, en1=airport)
This may be a workaround for you

  • AirPort connection hangs until clicking menu

    My AirPort connection seems to randomly hang until I click the AirPort menu. I've found a video of this problem on the web, but not a fix. Anyone have any ideas for a fix? I have all of the latest updates installed.

    If your Netgear router has been configured to disable its SSID broadcast, your first step should be to undo that and let it broadcast its SSID.
    Then try setting up your Mac again with your Netgear router being the "preferred Airport network" per:

  • Airport connection hanging

    Hey,
    I'm having a few problems with my airport connection dropping in and out, I've tried a few different wireless channels and it's the same on all, however when I change the radio mode transmission to 5Ghz (802.11n only or 802.11a compatible) it works fine. But... my flatmate can then no longer see the network on her windows laptop.
    Is there anyway I can get around this? ie. is there settings on her PC that will accommodate the change of transmission?
    Help! I can't play any of the stupid amount of music that is stored on my external HD and my net connection is painful.
    Thanks,
    Em.

    Hello emmakerf. Welcome to the Apple Discussions!
    Is there anyway I can get around this? ie. is there settings on her PC that will accommodate the change of transmission?
    To be able to connect, your flatmate's PC will require a wireless card that support either 802.11a or 802.11n operating in the 5 GHz radio band. Some of the newest models do, but not all. I suggest getting some information about this PC from the manufacturer's support site to see what it is capable of. Depending on the results, there would be at least three options:
    o Upgrade the PC with a wireless card that supports 5 GHz 802.11n.
    o Connect the PC to the AirPort with Ethernet.
    o Get a second AirPort and configure both into a "dual band" wireless network. With this type of network, non-"n" devices would connect to their "own" network.
    Setting up a "dual band" network is described in the Designing AirPort Networks document, starting on page 48.

  • Choppy airport connection after OS X reinstall

    I recently put a new hard drive in my 12" 1.33 GHZ iBook G4, which of course required reinstallation of everything. After I got everything back up and running, I've found that my airport connection, while showing full signal strength, gets little to no connectivity(pages take minutes to load, if not failing first). I'm using an 802.11b linksys router. The internet works fine when I plug an ethernet cable in to my iBook. Furthermore, a windows laptop right next to my computer works just fine with the wireless signal. Are there any setting that I might have forgot to change back after reinstalling OS X, or any updates/programs that may cause this kind of thing? Thanks alot in advance.
    iBook G4   Mac OS X (10.4.3)  

    Tried it. No luck again. I reformatted the drive and did a new installation of the OS. I was welcomed to Tiger and asked if I wanted to transfer info from another Mac. I said no, and I was then able to enter my basic info (name, address, etc.) myself. But halfway through the setup of the OS (right when I selected my wireless network) the computer screen went blue and that was it. No further activity for the next hour or so until I shut it off and gave up.
    I am wondering if the problem might have something to do with a faulty Airport card or something. The computer goes to access the wireless and hangs.
    Maybe.

  • Leopard: Air Disk hanging at "Connecting..."

    I can see my AEBS under shared in the Finder window, but it hangs on "Connecting..." and "Connect As" does nothing. Through Airport Utility, I have tried a number of times to set up different ways for it to connect. Nothing. Always the same result.
    FWIW, all worked great under Tiger.
    It's an Iomega Minimax 750 (and alternately an Iomega 1TB UltraMax), AEBS 1Gbit, and a Mac Book Pro connected via ethernet (WiFi turned off on AEBS).

    Hi Chris,
    patience is a nice thing. But the situation of many users here is a little complicated.
    Many of us have
    - bought a large external HD with USB to hook to the AEBS.
    - than bought leopard.
    Here it is not just about a feature which does not work. For example: If "spaces" would be the problem, nobody would care about that. You don't need to buy extra hardware for that purpose.
    Many of us are in a household with some Apple notebooks. We for example have one iBook and two MacBooks. No extra server, no always on separate desktop system which we could use to hook up the HD. I'm just lucky that "drobo" is not available in Germany, so I didn't spent 1000 Euros but only 145 Euros for the external HD.
    Second point: The AEBS is always dropping the connection the the HD. And after that I'm not able to reconnect again. I found in another thread that with a downgrade to a prior firmware for the AEBS this problem would be fixed. That must be a joke, or not?
    I'm using apple HW and SW because I don't have an IT department here.
    Apple: If someone is hearing me: Help!!! I didn't found a possibility to post bugs to apple on this particular problem.
    Best

  • Macbook airport connection drops and locks my computer

    So... I think my problem tops them all. Ive done alot of searching and ive found no topic relative to mine.
    - My intel macbook has an airport extreme that can succesfully connect to my schools network or my girlfriends network or my network at home. However...
    Many times a day... as soon as i make my connection active by going on a web browser.
    My Airport drops connection and locks my computer... only the mouse is avaliable, but
    anything else i try to click.. i end up with the spinning beach ball. Only solution i can find
    thus far is to force shutdown my computer and restart... Now i cant do a PRAM reset or
    start up in safe mode. I dont know how to solve this...
    Can anyone help me with this? It is incredibly annoying as i have to force shutdown my computer over 6 times a day which is... bad ... for my computer. More bad clusters.
    Thanks much ... G

    My problem is a variation on yours.
    I don't lose the airport connection at all. I can connect to my Airport Extreme base station and surf the Internet without a any hassle. I can see the other computers connected to said AEBS. Network drives are mountable.
    HOWEVER, as soon as I start to transfer a file or folder from or to a mounted network drive, the transfer hangs. The only solution is to power-off Airport to get the Mac to acknowledge losing connection to the network drive. Otherwise I would continue to stare enlessly at a frozen progress bar.
    Hopefully 10.5.2 will address the issue.

  • Lose airport connection after using boot camp and windows XP

    After using windows XP on boot camp and shutting down windows and booting to Mac OS 10.5.7 I lose the airport connection and have to restart or reset my airport extreme base station. My imac 2.8 is connected to airport via ethernet. Air port is operating on 5.7 version. This is a recent development and suspect it is related to updates in windows. I do not know where to start but need to solve this problem as it interrupts the other computers on wireless. Thanks Carl

    I have solved problem. It was in the windows settings using airport rather than ethernet connection. Carl

  • I seem to have lost some of my settings and now I cannot configure my airport connection. How do I get my settings back?

    Hello. First time using this. Still trying to figure out how to post my questions. I seem to have lost some of my settings and now I cannot configure my airport connection. How do I get my settings back?

    If you are using cable and a Nethear router sounds like from the information you provide before your Airport setting are setup improperly. PPoE is not something a cable service would need to work. Fallow the steps I will provide bellow, I will add some screen shots also to assist if necessary.
    1 - Open System Preferences from  (Menu)
    2 - Click "Network"
    3 - From the Network window you are going to wanna make sure Location is : Automatic and Show is : Airport
    4 - Once the Show: Airport is select you should see a window like this, my window is selected for Ethernet simply because I am no longer running Tiger but the window will look the same.
    5 - You will want to click on the PPPoE tab and you should see this
    6 - You're gonna wanna make sure " connection using PPPoE " is not select, if it is make sure to uncheck this option
    7 - Once this is uncheck make sure to click "Apply Now"
    8 - You will want to click back on to the "TCP/IP" tab and make sure IPv4 is set to " Using DHCP "
    9 - If the option to " Apply Now" is available again please click this
    10 - Once this is done go to your Aiport Menu and see if your network is listed and select your network and eneter the password if necessary.
    11 - If after these steps you still have issues I would recommend Power Cylcing your Router and Modem for about 5 minutes
    12 - Make sure all lights are off when unplugging the Router and the Modem
    13 - Some Modems have backup batterys so you may have to push in a tiny button on the back with a pin

  • Another airport connecting to internet problem! Please help!

    Hi, I'm having a problem connecting to the internet on my iMac G5 running OS 10.5.8.
    It initially started happening on and off after I upgraded from 10.4, now it happens all the time.
    Airport connects to the network (full 5 bars and I can see the other machines on the network), but can't connect to the internet. When I run Network Diagnostics, I only get as far as Select Airport network, but it keeps scanning forever but doesn't find the network. Meanwhile my iBook G4 and a PowerMac on the same network connect no problem.
    I get the Self Assigned IP address message in network preferences.
    I have searched the forums for this problem, and found lots of other people having the same problem, but none of the suggested fixes have worked. The only thing I can't do is reboot the modem as it's my landlords network and I don't have access to it.
    Things I have tried include:
    -turning airport on and off
    -deleting the airport preferences plist file from system preferences and rebooting
    -deleting airport from network preferences and adding it again
    -deleting all locations and creating a new one
    -using manual dhcp and putting in an ip address same as the ibook with 1 extra number at the end
    -turning of the firewall
    -rebooting rebooting rebooting
    None of the above works. Can anyone can suggest any thing else? It's driving me crazy! I know there are lots of other posts on this topic but I think I tried all of the fixes suggested without any success.
    Thanks

    There is a fair chance it's a problem with the DNS settings your ISP uses. Here is what I'd recommend.
    1. System preferences
    2. Network
    3. Click Advanced
    4. Click DNS tab
    5. Click + sign
    6. Add 208.67.222.222
    7. Click + sign
    8. Add 208.67.220.220
    9. Click OK.
    10. Exit System Preferences
    11. Try out your iMac and report what happened.
    Regards,
    Roger

  • Airport connected to modem but no internet.

    So I have the Airport connected to my cable modem but the Airport just blinks orange the whole time and the activity light isn't moving at all on the modem and I can't get online.
    I've tried unplugging the modem and Airport then like 15 minutes later I plug the modem in then 15 minutes later I plug the Airport in, but it doesn't seem to be working, any thoughts?

    Alright, so I called Apple and fixed it, so for anyone else with this problem here's what I had to do.
    I unplugged everything from the Airport and the Airport itself from the wall, held down the grey reset button on the bottom of it, while holding it down plugged it back into the wall and held the button till the light flashed green 3 times then went to orange and went back and opened Airport Utility and had to put in all my information again, holding down the button put it back to it's default settings.

  • Mac desktop and Airport Connection

    I have problem on My Mac desktop. I can't connect to my airport. my other devices had no problem with the airport connection. It shows full bar on my wifi bar but when I started to browse it tells me not connected to the Internet. I've tried resetting everything but no luck for me. Please help. Thanx!

    What specifically have you tried resetting? If you are seeing and connecting to your network then that's a big first step. I would try first to see if it's a settings issue. The easiest way to do this is to create a new network location and see if the issue persists. Go to System Preferences -> Network. Select the box next to the word "locations" at the top and select "edit locations." Hit the plus symbol and name the location whatever you want (I use "test" in these situations). Make sure it's selected and hit "done" and then Apply in the bottom right of the preferences page. Give it about 30 seconds and then try to browse again. If you're successful, it was a settings issue. You can now do one of two things: find the individual setting that was causing the issue in the other location, or just use the new location you've already created. You'll probably opt for the latter, which is what I would recommend. Very, very few users have a need for a particular location setting. If you're still having a problem then it may be more complicated to resolve. I would try it on another network (at a friend's house, or at Starbucks) to make sure it's not network related. Just because your machine is the only one not working doesn't exclude the network as the root of the issue. If you have problems there, I would consult your local Apple Store or Apple Certified repair facility as it may take some deeper troubleshooting to resolve.

  • Airport connection dropping off when computer sleeps

    Starting with the latest 10.4.8 update my airport connection drops when the computer goes to sleep. No amount of configuring will get the computer to recognize my airport. Turning off the power to the airport, waiting, and re-connecting does no good. The only way to get wireless is to restart. Once restarted the airport connection is re-established without any configuration and continues to be fine until the computer goes to sleep. Hard wiring ethernet works at all times without problems.

    thanks,
    i read the doc, looked in the system prefs where my re-connect was set to "preferred" and there was only one wpa network listed. i deleted it from the list then re-added per the apple document. will see if this works.
    in my own mind i don't think this is the solution but am keeping an open mind. the weird thing about my situation is that after the computer sleeps there are no available networks under the airport menu. i know in fact there are 4-6 in my area. after restarting the 4-6, including mine, networks are all there and my network has been connected to.

  • MacBookPro loses automatic AirPort Connection

    My MacBook Pro used to connect automatically to my Airport Express network everytime I opened up or turned on the computer. Recently I accidentally unplugged my Airport Express. Since then, my laptop no longer connects automatically. (In other words, the airport connection on the tool bar is shaded gray...) I have to connect manually from the tool bar every time I open up or turn on my laptop. Can anyone help me figure out what to do with the settings to fix this?
    The OS is 10.4.11.

    I have exactly the same problem after an ATT line issue which caused my DSL line to go dead. After fixing the line, Airport would not connect to my MacBookPro automatically. So I reset AP Extreme and could then find it but once I put the laptop to sleep or restart it, I have to manually connect to AP Extreme. The G5 tower has no problems and my iPhone is automatically connected

  • MacBook Pro 2008 Airport connections

    I know that a number of people have posted messages regarding the problem with Airport connections but I have not found a solution yet. My MackBook Pro 2008 has iOS 10.6.8. I can see Airport on (bold signal) but I can't access the interenet though I am able to use Skype. This had happened before but the problem was resolved by itself. The laptop works fine when connected by an ethernet cable. Can any one suggest any solutions please? Please note that I do not use Airport Exress or Time Capule as far as I know.
    Thank you.
    Prithvi.

    Can your MacBook Pro (MBP) connect to other wireless network AND gain Internet access, just not yours? Regardless, when a computer can connect to the local wireless network BUT is unable to gain Internet access, it typically is due to missing or corrupt DNS server information. Think of DNS as the Internet's version of a phone book.
    One simple test, is to enter the web site's actual IP address instead of its URL in your web browser. If you can now access the website, you verified that the DNS information in your MBP AirPort profile is incorrect.
    Another test, is to substitute a known set of DNS servers, like the ones provided by OpenDNS. Again, if you can access the websites by their URLs, it was the DNS servers information that was incorrect.

  • Loosing Airport Connections - Core Duo

    My AirPort connection doesn't work on MacBook Pro handed to me. No bars in the AirPort menu, no network shows.
    MacBook Pro 15", Intel Core Duo, 2.16 GHz, 2GB RAM
    Running Leopard 10.5.4 with all other Apple updates
    AirPort Extreme (0x168C, 0x86 - Atheros Card), Firmware: 1.4.3.1
    Every once in a blue moon, when the Mac was off for a while, it asks to connect to any wifi network around. It rarely connects to the selected wifi network and then only for about 5 minutes before it degrades constantly (watching it with iStumbler) and in about 5 minutes it's dead. When it connects iStumbler never shows more than about 50% signal strength.
    In order to get a signal at all I must be right next to the router, only to die after 5-10 minutes. If I try to join the network, it throws a "connection timeout" error.

    This happens on various networks (not just my home network with a Netgear router - mixed b/g, channel 6, WPA)
    I first checked on my router (switched channels, removed encryption, updated firmware, reset everything). Tried different wifi networks. Nothing would improve it.
    I've tried all of the Mac solutions I could find online:
    Removing the airport prefs, booting into safe mode, turning IPv6 off, DNS entries, removing and adding the Airport setup, turned the airport utility process off (I use a Netgear router), reset PRAM, Repair Permissions...
    I even reseated the card and the antennae (2) in case it was a bad connection.
    I finally erased everything and installed from the original disks 10.4.6 and tried upgrading slowly (tried 10.4.6, 10.4.11, 10.5.0, 10.5.1, 10.5.3, 10.5.4), all the way up to 10.5.4.
    iStumbler or AP Grapher find the network at the signal strength of about 20% while the Airport menu indicator can't see or connect at all.
    Any help would be greatly appreciated.

    Have you connected to the router using an ethernet cable? Try this to check that the signals are getting to & through the router. From my own experience it is most likely the wifi connection that is not working as it should.
    Make sure that you also do the routine maintenance things such as using Disk Utility to repair permissions. Errors here can affect some processes.
    I suggest that you also report the problem to Apple by clicking on the Contact Us link at the bottom of this page. On the screen that comes up choose the most appropriate link at the lower end of the RH column. I would include this copy of the System log. This is the main way we users have of getting Apple's attention. They don't promise any direct response but they will check the issue. You should also give them info about the router(s) you have had this problem with & any other info that might help them sort it out.
