Airport no longer working only on a single mbp on a single home-network

Hello fellows
Been recently foghting with this strnge,unreported issue,
The macbook pro is a 13" mid 2012 series.
The network router is a D-Link XXXXXXXXXXXX with DSL flat line.
All the other machines in there are just working FINE (1 15"2009 mbpro, 2 12" 2005 ibooks, 2 windows computers,2 tablets, 4 mobile phones) all connected by the same wifi
The faulty macbook pro doesn't connect either on airport and ethernet, a exclamative point icon appears on the top right after turning wifi on.
Until yesterday by sharing internet connection with the ither macbook or ibooks and hook it up via ethernet the connection was working, it stoppped suddenly like the way the airport malfunction started.
On other wifi networks, mobile tethering, on the 13" works perfectly.
Thanks in advance

  • Connect as... no longer works. Cannot connect to other computers on my home network.

    I have a home network and it's been unchanged for years. Never had any issue with connecting to other computers, all of which are Macs running OS X. Now, if I click Connect As, nothing happens. Double-clicking the other computer in the Finder's sidebar or using Go To Server, etc. yields nothing. Even odder; the other machines no longer see me at all. No one has any Firewall on. File sharing is on for all machines. We're all on the same subnet and the same network, yet every other machine can connect to one another but not mine. Thoughts? Restarting has not helped. Thanks.

    If you are getting the error message that the server won't allow any more users to connect, and to try again later, this seems to be a problem with AFP sharing in Lion.
    The workaround for this so far is to go to System Preferences > Sharing > File Sharing and click on Options...  On that window, turn OFF "Share files and folders using AFP" and turn ON "Share files and folders using SMB (Windows)" Click Done to go back to the sharing window and you should see a green dot followed by "Windows Sharing: On"
    Give that a try.

  • Airport no longer working after latest updates

    After my latest software updates, the Airport on my 13" Macbook is no longer working.
    I can connect to networks and can get full signal from the wireless router in my home, yet none of my browsers can actually connect to the internet.
    I've tried multiple wireless connections and none function properly. Suggestions?
    I'm currently connected directly to my NETGEAR router via ethernet

    Experiencing similar issue.
    Wired works forever without any issue. Wireless (airport) works for a while (random 2-60 minutes, could be related to data volume) then gets stuck. At that point getting back to wire (without reseting the airport AP) solves it. Also, cycling the airport client (disable/enable) gets it to work for a few minutes... until it gets stuck again. Other devices (iPhone, iPod touch) connected to the same airport AP do get access while the macbook is stuck.
    Thought this could be 11n related since the macbook is the only device running 11n. However, while wireless http/web access is stuck on the macbook one can still perform ftp connections (bit no file transfer as such), pings and/or access the time machine configuration (some of this seems to be randomly working) from that macbook. Not sure whether 11n handles short bursts and large bursts differently?
    Finally, the behaviour is the same whether using Safari or Firefox and relaunching eitehr app does not solve it.
    Clueless for now.

  • Airport no longer works after update.

    I occasionally use my imac as a base station to connect a laptop to the internet via airport. Since installing the recent security updates my laptop can no longer see a network (I also connect via a pda and this no longer works either).
    Airport indicates full signal strength but clearly there is no network.
    Tried deleting prefs but still wont work.

    Hi there BDAqua...
    I used this Pacifist software and followed instructions on this thread, rebooted, nothing seemed to change. Repaired permissions, nothing changed... I thought, oh well! Maybe I'll go to my local (Warsaw Poland) Apple repair centre.
    Sadly, I put my computer to sleep, about an hour later, opened it up with ethernet cable attached for internet, and noticed the wireless icon was now dark... lo and behold, clicked on it and my network was checked (this after having had my password "rejected" a million times before) and ... I carefully slipped the ethernet cable out of the socket... and I was still connected.
    So my wireless is working again, since doing all that stuff (back to prior firmware version) but for the life of me I don't know why, since it didn't seem to be fixed immediately after all that tinkering and rebooting! Any thoughts?? Did I actually do something that fixed it (must be, since I finally fooled around with it after almost 3 weeks of no wireless) or was this just random??
    This is far too un-Apple-ish, by the way! I was used to this with PCs, but first time I've ever had to get so technical with my Mac!

  • I have just installed iOS7 and now is my Airport no longer working. Very irritating. Has anybody an answer to this problem ?

    Just installed iOS7 and now my Airport express is no longer working. Very frustrating. Who has a solution to this problem.

    I'm curious what's happening for others with Airport Express devices that aren't working. In my case, it's simply now impossible to get sound coming out of it. All my devices and computers initially THINK it should work - they all show the Airport Express. But when I try to play, it doesn't work, with slightly varying responses:
    iPhone 5 and iPad 2, both on iOS7: if I choose the Airport Express, they continue to play as if through the Airport for about 20 seconds (with progress along the little progress/scrub bar), and then just stop playing. No error message or anything.
    On my computer, through iTunes 11.1: it thinks for a while, with the "Connecting to ___'s Airport Express" thing going at the top of the screen, until I get the "An error occurred while connecting to the airplay device ... the network connection timed out" message. The little chevron (?) in the upper left side, that lets us "Choose which speakers to use", becomes orange rather than blue, and when I click on that, the Airport Express listing now has an exclamation mark inside a warning sign.
    On an iPhone 4, with iOS6: basically the same as with the iOS7 devices. It seems to "think" it's playing through the Aiport Express, and then after about 30 seconds just reverts to the iPhone speaker and stops playing, with no error message.
    Note that through all this the Airport Express has its green light and seems to think it's working fine, with an "Excellent" connection, according to the Airport Utility.
    I've tried turning basically everything off and on; everything is as up to date as I can make it, except that iPhone 4; I've forgotten and added networks; I've reset network settings; I've added and taken away a password from the Airport Express Airplay speakers (because, hey, why not). I'm not sure what else there even is to do: maybe tomorrow I'll head in to an apple store and see if I can use the AirPlay from my iPhone to play on one of their Airport Expresses? If they even have any set up?
    Outside chance of the cause - could my wifi network somehow be confused because it's dealing with both iOS6 and iOS7? Does that make any sense at all? (Not that my wife is going to be the least bit eager to upgrade to iOS7 after hearing me swear profusely over the past couple of days!)

  • HELP! - airport no longer working after upgrade

    I performed the software update tonight (it prompted me for the first time tonight) to update the Airport Extreme Update 2007-001. Since I made the 'upgrade' I can no long connect to my home network nor any network I can usually get. How can I either fix this or roll it back?
    I have tried restarting, turning on and off the airport card. What else.
    Thanks,
    Dan

    Try trashing...
    /Users/nnnnLibrary/Preferences/com.apple.internetconnect.plist
    /Library/Preferences/SystemConfiguration/preferences.plist
    and the airport plist wherever that is... not on anAirport machine at the moment.
    Then reboot and set up your Networks again.

  • Since the update my password no longer works only on apple tv

    Since the update my password no longer works  on apple tv

    Cute.  I redid my apple password last nite and made it real simple.  It worked fine signing in to the forum just now.  When I use it to sign in on Apple TV  I keep getting message.  ' server not available'. I had gotten it to sign in earlier but netflix wouldn't play the movie.  Just the previews.   So I reset everything and tried to start over and I can't log on at all.  So if you have any helpful suggestions I would be interested in hearing them. Thank you

  • A connection timeout occurred. I have been receiving this error when trying to connect to the open wifi connection at my university. My wifi works perfect when I am using it on my home network. I have tried all the suggestions in forums online no luck.

    I am getting a connection timeout occurred message on my mid-2009 macbook pro I am running mountain lion 10.8.2 but problem occured before and after update. The message only happens when i attempt to connect to the wifi at my university. It works normal at my home. This error just started last semester out the blue. I have read many forums and non have helped ive reset my pram a few times, ive deleted all my networks including my home network out of my system preferences<network and all that extra stuff. if anyone has a clue please help me because one of my classes requires me to take in class test over the internet. Thanks for reading. If anyone can help PLEASE help ive been trying to fix for last few months.

    From the menu bar, select
     ▹ System Preferences... ▹ Network
    Click the Assist me button and select Assistant. Follow the prompts. You may get a warning that Wi-Fi is not available, that you're too far from the base station, or that you're using the wrong password.
    Assuming that you've ruled out those possibilities, click the lock icon in the lower left corner of the preference pane and authenticate, if necessary. From the Location menu at the top of the window, select Edit Locations. A sheet will drop down. Click the plus-sign button to create a new location. Give it any name you want. In the new location, set up the Wi-Fi service with the same settings you used before. Click Apply and test.

  • Airport no longer working after firmware update

    Before i get to my question, i think that it is necessary to give a bit of background as to why i have set my network up the way i have.
    I recently moved in with my girlfriend and brought my broadband package with me as i would have to pay a fee to cancel my contract within the contract period.
    This would be all well and good except that in the new location, the service provider can only supply broadband via an ADSL phone line (provided by a seperate telephone company) furthermore they (Virgin Media - i'm gonna name names) provide a cheap USB only modem - which in turn is only compatible with PPC Macs.
    Fine for me, but not so great for my girlfriend who has an Intel Mac Mini and not so great for my new Airport Extreme which of course requires a modem with an ethernet connection.
    Bearing in mind that it's just after Christmas and i can't afford to just run out and buy an ethernet modem or change my ISP - i thought that i would try something out.
    With the USB modem connected to my old PPC G4 i then connected the ethernet cable (that i had connecting our two Macs allowing them to share the internet connection) - from my G4 to the WAN port on the Airport...
    Now i'm a real networking newbie so i was a little suprised when suddenly and effortlessly i had created a wireless network that the Mac Mini and our iPod Touches could see and use. I set up security etc and all was well and good...for two days.
    Then Airport received a firmware update and now it doesn't work and resetting the Airport doesn't help.
    So now i have to get my hands dirty and like i say, i know jack about networks or the terminology.
    With this configuration - and obviously we know that it can work (somehow!)
    should i be in bridge mode or sharing a single IP address? and just how am i connecting to the internet. Static IP address/DHCP - PPPoE? I know what these abbreviations stand for but i don't know what they mean.
    In the course of 'playing around' with the settings i have seen a message saying that Airport has an invalid I.P. address - why is it invalid and is that only because of something that i have changed or is that the route of the problem?
    All the machines can see each other and the only clue i can provide is this log extract.

    I'm hoping that some networking guru is reading this and can provide me with a few pointers.
    Can anyone help? I've been struggling with this for days now.
    Thanks in advance.
    Steve.

    Your setup is convoluted, but it should work. A few comments:
    1. The base station should be configured to get an IP address using DHCP, which it will get from your PPC which (with internet connection sharing turned on) is now acting as a DHCP server.
    2. The base station should be configured in bridge mode, since your PPC (with intenet connection sharing turned on) is now acting as a router.
    3. I suggest you should turn off the network firewall on the PPC as long as your are running this sort of setup. Not ideal, but it will prevent all sorts of connectivity problems between the internet and everything downstream of your PPC's ethernet port.

  • Updated to 10.6.6 - Airport No Longer Works

    I have a Black Macbook from about 2-3 years ago. It's been great throughout it's lifespan so far with hardly any errors and the errors I have encountered were always minimal and had quick fixes. That was until this recent update to 10.6.6.
    Once I updated it, I could no longer connect wirelessly, anywhere. When I first select the airport drop down from the toolbar the first time I would see the local network/s and be able to select one. However right after selecting one it would give me a connection timeout and then the networks would completely disappear from the network selection area.
    I hadn't really thought it was because of the update, I thought maybe I accidentally changed a setting or something around those lines. Well I have a friend that wants to buy my MacBook once I can upgrade (MBP). So I decided I'd just totally reset the MacBook back to the factory settings. I erased the Macintosh HD and installed Snow Leopard. Everything was perfectly fine and it was working just like new. So after moving over my music, movies and a few apps I decided I'd update it back to 10.6.6. Once I updated it, the Airport acted just as it did before (this is how I found out it was the update that screwed up the airport).
    Are there any fixes? The furthest backup I have is from after the update (I had to get a new HDD because my other one crapped out). I have all my files, disks for apps, etc, etc so I'm not worried about manually moving / installing files, etc. I'm going to reset my MacBook back to factory settings tonight again and simply not update it. However if there are any fixes to this problem I'd greatly appreciate it, I don't want to be stuck in 10.6.5.

    There are a lot of variables to a network problem.
    There are also many threads of varying degrees of problems on here I've been reading over the past week about 10.6.6 having DHCP drops, slow speeds, all the way to this one, of no connection at all.
    Everyone has the same solution, for sure...downgrade. If you want a 100% absolute (barring a hardware failure, of course), that is your answer.
    Had you not downgraded, a guy in the UK went through just about every single troubleshooting thing I could think of/find in this thread here:
    http://discussions.apple.com/thread.jspa?threadID=2710675
    The only thing that finally worked for him was OnyX, which to me means it's a preference or cache file somewhere that they know about, and I didn't. Which is why I'm recommending running that in this thread first, before all of the other things I suggested he try.
    Here is a link: http://www.apple.com/downloads/macosx/systemdiskutilities/onyx.html
    It's free.

  • Airport no longer works with my MacBooks. Help an old lady get wireless again!

    First, I have to tell you that I'm as dense as granite when it comes to technology, so please talk to me in the simple terms you'd use with a dazed higher primate. Assume that I know nothing.
    My story: I have the world's oldest MacBook Pro and am also using a new MacBook Air. I had a new Airport base station that was working fine with the MacBook Pro until I moved two years ago. I know nothing was dropped or mishandled, because I moved the electronics myself. But when I set up stuff in the new house, with Airport in a spare room and using the laptop in my bedroom where I have little room for anything but me, the MacBook would no longer recogize the Airport.
    I tried moving Airport into the same room, thinking there might be something wierd with the walls of the house, but still no dice.
    So I've been wired to the Comcast modem ever since. I trip over cables so often, I can do it in the dark.
    Things are getting complicated now, because I've added a printer/scanner. Since I can't use it wirelessly and don't wish to trip over the cable every time I stand up, I hardly ever use the thing. Also, I'm shopping for a new TV and have dreams of being able to connect it with the Mac for watching movies, etc. The thought of using more cables makes me sad.
    BTW, I'm currently using a borrowed MacBook Air, circa 6 months ago. It doesn't recognize Airport either. Airport is currently sitting in its box, bored and depressed.
    Since nothing I own is under warranty any longer, I'm looking for free advice here instead of paying Apple by the hour.
    Two questions:
    (1) the ****? How do I get wireless again?
    (2) Is Airport interchangeable with other wireless modems, like the one Comcast offers me?

    When you connect your MacBook Pro to the Comcast modem using its Ethernet cable, you are establishing the same sort of connection with it that would be used by your AirPort sitting in the box. The modem does not care what is connected to it, but it can connect to only one device at a time. Most of them "remember" that device as long as it is powered up, and will refuse to communicate with anything else.
    So the first thing to do is power down the modem. Unplug it. Then, connect your AirPort's WAN port to it (Extreme or Express, whichever one you have) and then power them both up. With any luck your MacBook Pro might just connect wirelessly like it used to in your last home.
    If it does not, you probably need to reconfigure the AirPort Base Station again as if it were new. To do that, "hard reset" the AirPort Base Station by pressing its tiny reset button and holding it depressed long enough for its LED to flash rapidly. Then, the LED will glow solid amber for a moment or two, then it will begin to flash slowly. When that occurs select its network in your Mac's Wi-Fi menu. Its name will be "Apple Network nnnnnn" where nnnnnn = a code unique to your base station. Select it.
    Then, launch AirPort Utility - it is in your Utilities folder - and it will detect that your AirPort base station has been reset. Click the Continue button, answer the questions, and it will reconfigure the AirPort to those settings. The questions should be self-explanatory. When you are finished you will be prompted to restart the AirPort.
    The next step confuses people, because after restarting the AirPort Base Station the network name that you had been using to configure it immediately ceases to exist. AirPort Utility may as well just sit there forever so just quit AirPort Utility. You have to manually select the network you just created by selecting it in the Wi-Fi menu again.
    If you run into problems and need more help, meaning you must communicate using the Internet again, just remember the first paragraph - power down the modem whenever you change what is connected to it. Make it a habit.

  • Airport no longer works after resuming from sleep

    I got a new MacIntel a month or so ago, and it has always done this, under 10.4.4 and now 10.5.5
    When resuming from sleep, airport shows full strength for second, then the signal disappears. NOTHING in settings, reconnecting etc will get it to work again. (this is 'deep' sleep, not just the display turning off)
    If you restart (restart not shut down), then when it comes back, airport is just gone - even the menu bar indicator. The computer now thinks it has no airport installed at all. No matter how many times you restart, there is no longer any airport.
    If you shut down, wait a minute and restart, it works as normal.
    Since airport is the only way I connect to the network, and I don't want to waste electricity, this is unacceptable and clearly a flaw.
    I called tech support and they had me move airport to the top of the list, delete plists and other stuff, none of which made any difference. I'm thinking this is a low level system software fault, and I hope I don't have to take it back for a motherboard replacement.

    I also have this problem, although, not very often.
    I'm still running 10.4.4. This never happened with
    prior versions. Rebooting is the only way to
    correct the problem. Simply turning off Airport and
    turning it back on does not help.
    Thats interesting actually because I Never had any trouble on my G5 iMac of otherwise identical specification, on on intel. Hmm. I was thinking this was an intel issue.
    Wonder if its a hardware problem (though I suspect not).

  • After update Airport no longer works

    Hey All,
    I've had my PBG4 for over a year now and have a APE Base to go with it. About a month or so ago I ran the apple update program and walked away while all the programs were installing. Upon rebooting my laptop I no longer see my base station at all. The base station is located 4 inches from the laptop while I'm home. I do no remember which patches were installed at the time. I am assuming that it was an AirPort patch that is causing this issue but I can't tell it if it was the base station that upgraded or the airport card.
    Currently I am cabled into the base station directly but I'd like to be able to go wireless so I can use the laptop around the house again.
    Anyone got any info/ideas on this?
    Also I'd revert back to an old version to test it out but I read in a couple of posts that you can't scale back.
    - Pete

  • New Security Update - Airport no longer works. Help ?

    Hey all
    this morning I ran various software updates: itunes, safari and the new security update. From that moment onwards, I cannot access the internet using my MacBook (about a year old, running Mac OS X 10.4.11). I normally use Firefox to access the net, but neither that nor Safari work now.
    I know my internet works as I can access it wirelessly using my work laptop and my desktop.
    But when I try to access my broadband using my macbook:
    a) the "waves" on the airport all remain light-shaded
    b) I receive an error message saying " There was an error joining the Airport network 'Zyxel' " (the router is zyxel).
    If anyone has any thoughts on how to reset the connnection back to how it was, I'd be EXTREMELY grateful.
    thanks
    B

    Having the same problem, but only with my Mac. PC and iPhone continue to work fine. Must be security update related. Is there a way to uninstall the security update?

  • Airport no longer works with WPA, WPA2 or WEP after 10.4.8 update.

    A little disappointing.
    After updating to 10.4.8 (I first did Software Update, then read here that the downloaded is safer, so I downloaded, repaired permissions, rebooted, installed 10.4.8 again from the download, rebooted, repaired permissions once more)
    Now when I try to use the Airport on my MacBook Pro 17" I cannot connect to my wireless router (DLINK-524) with any security turned on (WPA, WPA2 or WEP). The signal strenght flashes on full (I'm close to the router) and off and I do not connect.
    Any clue how to fix this?
    Macbook Pro 17" Mac OS X (10.4.7)
    Macbook Pro 17"   Mac OS X (10.4.7)  

    I just did that - I tried a rollback with an "archive and install", and then stopped at 10.4.7. My problems persist... I'm actually quite amazed! Qurious if a clean install would solve the issue, but not curous enough to try. The way i see it, a re-install (even doing an "archive thingy") should include resetting all drivers. Well, either I am wrong and they are saved along with user settings - or else your explanation seems the only viable one; that there was a firmware upgrade included in this install. I admit - I did NOT read any readme. On the other hand, I tried my first install using the normal update.
    =)
    Anyway, after deleting all system prefs, deleting and reconnecting networks, repairing disk permissions and key rings, deleting keyrings etc. etc. - doing it all over again in different orders etc., I tried "arhive and install" back to 10.4.7. When that doesn't solve it, I give up. I have now opened my network - disabled crypt, and settle for simple connection control on MAC adresses. That works.
    I would REALLY appreciate a fix, ladies and gentlemen on Apple. I mean really as in I am gonna egg your house if you don't give me...
