AirPort doesn't work

Last night my airport stop working on my macbook 2.2 with Lep. And its not the wireless connection because i still get the connection with my iPhone. Any thoughts on how to fix this?

have tried to delete the network and reconnect.
Users often "delete" the network from the Network settings.....System Preferences > Network > AirPort......but they do not delete the listing about the network password, which is stored in KeyChain Access.
If you do not also delete the listing in KeyChain Acess, you have not deleted the connection.
Open Macintosh HD > Applications > Utilities > KeyChain Access
Look for the listing with the name of your wireless network
Delete that entry
If you still cannot log on on the wireless network, try changing the name of the wireless network and password on the wireless router to establish a new network to see if the Mac will connect to that "new" network.

  • AirPort doesn't work after Leopard install

    I have an iMac 20" 2GHz Core 2 Duo and my AirPort doesn't work. I reset my PRAM, erased the hard drive and installed a clean copy of Leopard after picking it up from the Retail store. I had exactly the same problem with 9A559 and the seed update and I ASSUMED it would be fixed by the time the final release is out. It doesn't detect any networks, even if i move the access point very close to the computer. I tried disabling all security on the access point. Tried changing channels. Tried resetting the access point to defaults and reconfiguring from scratch. Tried manually putting the SSID in on the iMac but none of it worked. The access point is a Linksys WAG54G with the latest firmware. If anyone can help me, please do because the AirPort is the ONLY way this computer can access the internet.

    Just to clarify my situation:
    Erase and install of Leopard
    Airport card is detected:
    Wireless Card Type: AirPort Extreme (0x14E4, 0x89)
    Wireless Card Locale: Worldwide
    Wireless Card Firmware Version: Broadcom BCM43xx 1.0 (4.170.25.10)
    Current Wireless Network: wireless network not available
    No networks are available for selection, (i can normally see 4 or 5)

    I'm about two feet from my wireless router, none of the other (Tiger) computers have issues connecting to it.
    Anyone else see the Apple80211Scan entries?

  • DHCP & self-assigned IP problem-Airport doesn't work

    I'm not really a technical type, but I'm pretty quick to pick things up and several weeks of trying to deal with this issue has made me pretty knowledgeable about things related to it specifically.
    Background:
    I have a month-old Macbook Pro that runs Snow Leopard and is up to date on all its software stuff. On our home network we have another pretty new Macbook Pro running 10.5.9 and a fairly old Macbook also running 10.5.9.
    We have a Linksys WRT54G wireless router. Our network uses a 40-bit Hex WEP password.
    Problem(s):
    When I try to connect to our wireless network, Network preferences tells me that it cannot connect because of a self-assigned IP address. Sure enough, the IP address DHCP comes up with is of the 64.XX.XX.XX variety. Google's revealed that this is a common problem for all recent versions of OSX, back to at least Tiger.
    The "subnet mask" it comes up with is 255.255.0.0, which is different from the settings on our other (working) computers, which is 255.255.255.0. I'm not sure what this means, or whether it's significant. Renewing the DHCP lease either comes up with the same 64.XX.XX.XX type or, sometimes, it comes up with no IP settings at all. The most frustrating thing about this is that if I chose "DHCP with manual address" and type in any in our set that I've confirmed isn't in use and hit "apply", as soon as I go back to the panel it has reverted to the 64.XX.XX.XX type.
    I've also tried manually entering the router/subnet mask/IP data, as well as the DNS numbers, and that leads to the Network Settings connectivity dot thing being green, but the internet still doesn't work. In those cases, diagnostics claims that everything is fine up to and including the ISP, but that it's unable to connect to the server and internet.
    Of note: some people with a similar problem have talked about networks with this problem working intermittently, but mine seems to be consistently broken.
    Initially I was able to avoid fixing the problem by using our neighbors' unsecured wireless network, which is sort of awful, I know, but at least it kept me from having to deal with this for a while. Today it started to do the same thing to that network. Both networks continue to work on our Macbook and other Macbook Pro, which is why I don't think that it's a router problem.
    I've been able to connect to our other computers through computer-to-computer networks—going through our main shared network (and thus the wireless router) doesn't seem to work—which I think shows that the Airport card/hardware itself is intact (?). I did try connecting to the internet through the "internet sharing" option on our Macbook, but that had the exact same problems.
    Another thing that may or may not be relevant, but is equally infuriating:
    I've also noticed that my Macbook Pro has more trouble staying connected to a network than our Macbook—even when it was working, it disconnected/timed out extremely often, which is something our Macbook never does, even from the same location. When I try to connect to a network it spends a very long time displaying the "searching for network" animation in the menu bar icon, sometimes after the Network Preferences pane believes that it's connected, and sometimes even after I hit the button to turn Airport off. It's also started refusing to connect to any networks at all, on occasion, which is especially evident in the process of the diagnostics box thingy, because there it actually tells me it's unable to connect rather than just playing the searching animation for ages.
    Here are some other things that I've tried:
    setting up a new 'location'
    restarting the computer
    deleting the airport preferences file
    restarting in safe mode
    restarting open firmware
    confirming that the firewall allows all incoming thingies
    resetting the router
    making sure the keychain password allows all applications to access it
    connecting to the internet through a computer-to-computer network from another machine
    Because the situation has deteriorated over time, I'd also like to know whether people think that it's two problems (the type of router then later the airport hardware(?)/software(?) itself, perhaps) or just one. Since I've tried basically everything besides switching out our router, I'm kind of inclined to blame it on that, especially because one of the more plausible explanations for this problem that I've heard is a time-out error due to Airport expecting a faster response than it's able to get from older routers; however, the fact that other networks haven't been working means that it's not likely to be just the router. If it's just one problem, which is the simpler explanation, then I guess there's something properly wrong with my computer's software, in which case I guess I'll take it to the Apple Store. :/
    I'm in love with my computer otherwise, and I'll admit that I spent a good twenty minutes sobbing out of frustration over this. Any help would be immensely appreciated.

    HI and Welcome to Apple Discussions...
    Try Changing the Airport Channel
    Open AirPort Utility, located in the Utilities folder in the Applications folder on a computer using Mac OS X.
    Select the device you’re setting up, and then click Manual Setup. Enter the base station password if necessary
    Click AirPort in the toolbar, and then click Wireless.
    Choose a new channel from the Channel pop-up menu.

  • Airport doesn't work after firmware update

    Hi.
    I was using my home wireless network when the Software Update suggested a firmware update to my Airport. I did it, but since then it doesn't work any more. I mean, the Mac can't find it and it keep flashing the yellow light.
    Have this happened to anyone else?
    Thanks.
    Best regards,
    T

    Try shutting down the DSL modem and your AirPort base station. Leave them S/D for about 5 minutes, then start the DSL modem, allow it to complete its test cycle, then start the AirPort base station.
    Repair Permissions - /Applications/Utilities/Disk Utility.app. Start Disk Utility, select your HD and click on Repair Permissions. When finished, quit Disk Utility and then restart your computer.
    Go to System Preferences/Network/AirPort
    - click on the 'Network Name:' roll-button, select 'Join Other Network...', enter 'Network Name and select the security type you are using, and finally, enter your Password and click 'Join'.
    - click on 'Advanced', TCP/IP and confirm that 'Configure IPv4:' is set to 'Using DHCP', click 'OK'.
    - click the 'Apply' button and exit System Preferences.
    If the above does not work then a factory reset of your AEB might be in order. The setup manuals for all AEBs are here: http://support.apple.com/manuals/#airport

  • Airport doesn't work after RAM install

    I upgraded RAM on my Mac Mini. Followed directions and all is good. Mini with new RAM is running great; however now, my Airport doesn't see my or any neighborhood networks. Prior to the install this was all working fine.
    I can' figure out the problem. Any suggestions on what to do?

    Excellent! That was it. Thank you.
    And notes from a novice: For those looking to upgrade RAM in the Mac mini (Intel) there are 3 things to note when pulling out the internal frame: 1. The little black (thermostat fan) cable up front. You must unhook but if you forget to reconnect the fan runs all the time. Not good; 2. The gold (audio) band in the back. This too came off very easily. Very small (plastic) clamp that was tedioius to set back. Lift internal frame and turn like a book page; and 3. the airport cable. There are 2 small circular (beige color) ports. Use the MAIN (it's in tiny print) near the back.

  • Moved houses.. now airport doesn't work

    Hello,
    I just moved houses and stayed using the same internet provider (comcast high speed internet cable modem). I went to the new house and plugged in my macbook pro and it got on to the internet no problem using DHCP. Now I went to set up my airport extreme, and I set it using DHCP and tried to connect, and it just sits there when it tries to access a page. I was using in my own house an airport extreme linked to another using WDS so I could extend the range and it worked no problem. I tried on both of them just using DHCP and it doesn't seem to work. I tried doing a hard reset on one and setting it up using the assistant, and still no luck. I even programmed in the values that I get when I use my ethernet connection as a manual setting in the airport, and still no good.
    Any ideas/thoughts would be appreciated, I am stumped as I figured DCHP should just work.. I do not use any domains/other routers quite yet, and I don't see what the problem should be.
    Thanks so much for your help in advance!

    Unplug your cable modem from it's power supply, leave it unplugged for at least 3-5 min. Hard reset you're base station again, if you've got an express, do a factory reset. see article http://docs.info.apple.com/article.html?artnum=108044 for instructions. use the setup assistant again, and make sure you set it up like it's brand new. new base station, new network, new everything. plug your modem back in. you should be good to go.

  • Took My PB apart, put it back together and AirPort doesn't work

    Hi
    I recently aquired a Powerbook G4 for nothing because the Optical Drive was broken, I used an iFixit Guide to try and fix the optical drive, I didn't manage and the computer wouldn't start so i took it apart again and disconnected the optical drive, the computer started up again but now doesn't see the AirPort card for some reason
    Has this happened to anyone else? If so please help
    Jonathan

    The AirPort was working fine when I got the machine, and the first thing I did when I got it was clear the hard drive and put a clean install on, I also tried resetting the NVRAM but it didn't help, all the other ports seem to work, myabe I damaged the AirPort card when I took it apart (I did remove it several times|) or maybe the slot it goes into (to get to the optical drive you have to remove the logic board)

  • Airport doesn't work when using a second monitor

    My macbook pro, purchased mid-June, is exhibiting an odd problem. When nothing is plugged into the mini-displayport, everything is fine. If I plug my external monitor in, and the display is being mirrored, whether the lid is open or not, once again, everything works perfectly. Once I switch into extended display mode however, my wireless connection drops after a few minutes and refuses to reconnect.
    It is definitely not a signal issue. The second I unplug the monitor, my wireless connection returns to normal even if I don't move the computer an inch.

    Hello,
    I have the exact same issue: whenever I am using my external display, my wireless connection with airport immediately stops. Same June 2009 macbook pro for me as well.
    If I go down to the lowest resolution (640x480), I can get it to connect. The moment I unplug the external display, the wireless connection with airport is re-established.
    This problem has been reported on the apple discussions forums by a few people. Someone mentioned that it could be electrical cross-talk between the graphics card and wireless card internally, one causing noise for the other.
    Anyone have a solution? Or have the same problem?

  • Re-install Tiger, Software Update, now Airport doesn't work

    So, I just replaced the hard drive on my Dual USB iBook G3. I completed the installation, and everything was working great. Airport was showing my home network (unsecured, iknow) and I was able to connect to Software Update via the Airport.
    First major download was the 10.4.8 combined update for PPC - after downloading it and restarting I lost Airport connectivity. Can't find my newtork, can't manually input IP address, etc.
    Next, plugged into Ethernet and downloaded Airport (4.2 ?) and still nothing.
    What's the deal? Airport was working before the updates, and now nothing. Other laptops at home are working wirelessly just fine, so it's not my ISP, connection, or router.
    Help!

    Hi sockdaddy, welcome to Apple Discussions!
    Click here to be taken to the Airport Troubleshooting kBase document.
    It could be that you need a firmware update following the 10.4.8 update. Follow the steps in the above link, and post back with your results.
    Another thing to try is the Mac OS Software update. Click on the Apple logo at the top left of screen while connected to the 'net, choose 'Software Update' and let the computer do the rest.
    If all else fails, remove and re-seat the Airport card by following these instructions.
    Let us know how you go.

  • Internet sharing via airport doesn´t work

    Hello to everybody,
    my problem is, when I do internet sharing via Airport on my imac (OSX 10.6.8) so I can use my ipad for surfing. The connection establishes for a short time and then it breaks down. Once in a while I can reconnect, but it´s constantly breaking.
    I know, this problem is posted a million times, but it still seems not to be solved (or I didn´t find the right thread with the solution).
    Bthw. I phoned the apple support. They wanted to charge € 49,--. Now I´m quite mad at apple. This *****. They are having a problem with their software and they want to charge me? That´s incredible. I can´t understand what´s the hype about apple. Such an awfull bad support they´re giving (or not giving at all).

    OK. To your information. Today I tried the following: I switched off and on internet sharing twice after boot and voila, wifi seems to work fine. Yeah, that´s what I call a sophisticated computer system. Really crappy stuff!

  • Macbook Airport doesn't work on AC power

    Yeah, that's basically the deal. My airport decides that when it's connected to the charger, it randomly drops out (ie the signal thing greys out). If I click back on it, the network has disappeared and I can't get back on unless I unplug the charger from the macbook and restart.
    it seems to be opposite of the problem that everyone else is having.
    any ideas?
    I have 10.4.11 with a WRT54G. Definitely not a signal issue, full bars on all PCs and the macbook when it connects.

    My wireless is password protected and when I type in the password it says "connection timed out"

  • RAM upgraded – Now Airport doesn't work

    So I upgraded a G4 1.33 iBook this morning, boosted the RAM from 256MB to 1.25GB using a 1GB chipset.
    After the RAM installation was complete, I booted the machine, first resetting the PRAM using apple-option-p-r, then resetting the NVRAM using apple-option-o-f and the "reset-nvram" and "reset-all" commands.
    The iBook booted up perfectly, but is now unable to detect any wireless networks. Any idea how to solve this? I thought I'd plugged the AirPort card back into the iBook properly and reconnected the aeriel correctly, and it all looked OK.
    Help!

Its driving me nuts!!!

    We had the same problem, but figure out the solution.
    You MUST have at least 1 song added to your ITUNE!  After you add a free song, then everything else should work as normal!
    Hope this helps!

  • Airport password doesn't work, how do I change it?

    I locked my airport after using it for ages in an unlocked format.  Now I am not able to get into it for the purpose of reconfirguring it.  The password I used to secure the lock doesn't work.  Is there any way to change a password when you don't know what original password was entered?

    You can temporarily disable wireless encryption by performing a "soft" reset on your AirPort Base Station. Once connected, you can use the AirPort Utility to change the password.
