Q: Upgraded to 10.5.3 and then no more Airport - HELP !

Hello,

I have WIFI LAN access issue after upgrading an IMac G5 to from Tiger to Leopard, and would appreciate your help.

ISSUE :
Prior to Leopard, this IMac worked on 10.4.11 with access to my WiFi AN via an Airport Extreme Card.

After I installed Leopard 10.5 straight out of the DVD :
the Airport icon on the menu bar is grayed out as if it did not pick any signal, although I did not change location nor LAN settings
when I want to access to the LAN, it requests the 24 characters WPA password, but although I know the password is correct, I get a “connection failure” or “connection timeout” error message.
I get the same messages when I try to configure access from the Network preference pane.

A a result, I cannot get nor on my LAN, nor on Internet from the G5 iMac.



UPGRADE HISTORY AND SOLUTION ATTEMPTS
I performed a simple upgrade from the DVD (ticked off the X11 option and languages translations though).

Then I also reinstalled the Airport Extreme Software form the CD, in case Leopard “erased” an Airport Extreme driver...

I also reinstalled Leopard with an “Erase” of the Hard drive,
to have a full clean start...

Last, I upgraded the system to 10.5.3 with the combo update that I downloaded from another computer, hoping that I would resolve this possible issue.

I tried to find firmware updates, but no success...


SYSTEM DESCRIPTION
This is a LAN for home use for 3 Macs :
my Mac a Dual G5 1.8 MhZ under 10.4.11, works OK. I did not upgrade.
my wife iMac Intel Core 2 Duo 1.83 MhZ, upgraded to OSX 10.5.3, works OK
my kids iMac G5, bought second hand with Tiger, does not connect after 10.5 upgrade. I bought back then also an Airport Extreme card and updated the Airport Extreme Software (CD version 4.2, 2Z691-5417-A), since then it worked fine.

The LAN is managed by a wireless router from Italia Telecom (I live in Turin), here are some specs of the router :
Alice Gate 2+ (http://aiuto.alice.it/informazioni/m.../alice_w2.html),
- standard ADSL (these refer to the Italian telecom compliance)
- ITU G.992.1/2/3/5 Annex A
- ANSI T1.413

- Protocols :
- RFC 2516 PPP over ethernet
- RFC 2684 - formerly RFC 1483 and RFC 2364

- Support for ATM UNI3.1, UNI 4.0
- IPTV functionality via Port mapping
- OAM F4/F5 Loop Back

- Interfaces :
- ADSL Interface, connection RJ11
- USB interface full speed (12 MBPS), connection B type, compatible USB rev 1.1
- Ethernet Interface, RJ45 connection, compatible with IEEE 802.3 10/100 Base T auto sensing
- WIFI IEEE 802,11/g Interface :
- max speed transmission 11/54 MBPS
- encrypting with key :
- WPA with pass word of 24 ASCII characters (WPA PSK 256 bits key)
- WEP of 128 bits (13 ASCII characters)
- supports WiSeConf (TM)


THANK YOU for any help, I would hate to have to switch back to Tiger...

    Welcome to the home of sick Mac's!

    Thanks for providing so much information. It all helps...

    As a starting point, I am assuming that you are able to connect via Ethernet, and that you have control over your router.

    1) Create a new location. System Preferences -> Network -> Location. You can duplicate the existing location. Leopard has a history of not being happy with the Automatic location.

    Delete and recreate the entries for your network within this location

    Airport -> Advanced -> Airport


    If this does not work:

    2) Remove security from your router (temporarily).

    Report back!

    Cheers,

    Rodney

    p.s. Turin is on my list of "must see" holiday destinations!

    Hello,

    thank you for picking my post.
    I think we are getting somewhere :

    I created a new location, but no resolve.

    I then removed the WPA security :
    the airport signal icon is black and the airport preference does name the LAN,
    so I guess I am connected, but when I launch Safari, the page displays
    "not connected to internet"...

    When I put the WPA security back, it behaves like before.

    mystery....

    When you are connected (without security):

    Go to System Preferences -> Networks -> Airport.

    Does it say something about a "self-assigned" IP address? Does the IP address begin with 169.254..?

    I have this same problem.

    However, my network preferences can't be accessed. I get a "Preferences Error" pop up saying "Could not load Network preferences pane".

    Hello,

    In System Preferences / Network / Airport I get the following message :
    "Airport as a self assigned IP address and may not be able to connect to the Internet"

    In the Advanced Network Preference :
    - the Airport toggle shows the network name
    - the TCP/IP toggle shows the following options :
    Configure IPV4 ; Using DHCP
    IPV4 Address : 169.254.120.9
    Subnet Mask : 255.255.0.0
    Router :

    When I look at TCP IP from the othger Macs, I get :
    a different IPV4 address (192.168.....
    a different Subnet Mask (255.255.255.0
    an Router nr : 192.168...

    If I try to reconfigure the iMac on similar TCP/IP than the other machines using the Manual DHCP,
    the thing does not work.

    Mystery pt 2...

    Sorry mate - this is a separate problem, and would be best addressed by [starting another thread|http://discussions.apple.com/post!default.jspa?forumID=1222]. It gets too confusing to solve 2 problems in the one thread!

    Cheers.

    Hmm. Obviously something is going astray. It is possible that something in your system has :locked up". I have a few suggestions:

    Leave your setting on "Using DHCP"

    1) Try deleting /library/preferences/systemconfiguration/com.apple.airport.preferences.plist

    You may need to re-enter your network settings after doing this.

    If this makes no difference

    2) Remove /System/Library/Extensions/AppleAirport2.kext and /System/Library/PrivateFrameworks/AirPortConfig.framework if they exist. They are remnants from Tiger or earlier, and not used in Leopard. http://discussions.apple.com/message.jspa?messageID=5684223#5684223

    After doing this, open up terminal and enter:

    sudo touch /system/library/extensions

    Reboot. This will force the rebuilding of your kernel extensions cache.

    Hello Rodney,

    so far, nothing : I tried the procedure you mentioned twice, but still same symptoms :
    Airport full signal, link to the LAN, still no connections from Safari...

    One thing though : in /System/Library/Extensions/AppleAirport2.kext, the file that I deleted was named "AppleAirport.kext" and not "AppleAirport2.kext". Don't know if it helps, but I thought I'd mention...

    I wonder if there is not an issue with the IPV4, Routers and submasks...

    Ummm... You will need AppleAirport.kext (that is still used in 10.5). I hope you didn't delete it fully. (There are ways of getting it back if you did).

    I'll have to research/think for further solutions to your main problem.

    I have the same self-assigned IP address problem on an old ibook which is connected to a Netgear modem via a Time Capsule. The problem occurs on waking from sleep and less often on startup. It's transient, but has been becoming a lot more frequent. Since it's limited to one of the four machines that connect to the network, I've been assuming it's about that computer and not the time capsule or the modem.

    I've tried the fixes listed above (assigning a manual address, deleting preference files etc) as well as a few others (deleting the relevant passwords from the keychain and re-entering them in the hope that it was at that point the problem was occurring) and none of them have solved the problem.

    I then came across a suggestion in another thread about this problem suggesting it might be the firewall. So I tried turning off the firewall (which is set to allow access for specific services and applications) and voila, the ibook received its IP address as it should the next time it woke from sleep. I tried putting it to sleep a few more times and waking it, as well as restarting it and repeating the procedure, and each time it worked, which was interesting.

    Obviously having a computer with no firewall is not a great solution though, so I turned the firewall back on, and this is where it gets interesting. Because since turning it back on the problem seems to have stayed fixed.

    I'm not enough of a techie to know what this might mean, but it might also be worth mentioning that the ibook throws up a pile of annoying incoming connection requests every time you start up - do you want to allow kp-something-something access etc etc, and a little while back I tried to stop this by creating an allow incoming settings for the kp-something-something request (since I've now deleted it I don't remember exactly what it was, but it's something other people have complained about). This didn't work, and I actually deleted the line in the list of File sharing (AP) settings while I was in the firewall settings trying to fix this problem. Even more interestingly, since I turned the firewall off and on again these requests on start up seem to have stopped.

    I also have a suggestion for anyone who can't get the firewall trick to work, which is disable the password access for your machine and add use MAC address filtering on your router to try and get in that way. I don't know if this will work, but it might . . .

    Hello,

    how do you turn the firewall off ? Is it the LAN WPA encryption ?

    BTW, this definitely has got to do with the Imac G5 and Leopard because
    I installed back Tiger and the Internet worked fine, then I upgraded again to Leopard,
    and even to 10.4:5 and the problem came again.

    This is very very annoying, an upgrade that screws up my networking !

    My problem was with a self-assigned IP address, so the fix I outlined above is only likely to work if that's your problem.

    Either way, the firewall is under Security in Network Prefs. Try turning it off, click back to Network and wait for a few seconds. If your problem is the same as mine the Airport should reset itself from Self-assigned IP address to connected in a few seconds. It then stays connected even once the firewall is turned back on. MAKE SURE YOUR FIREWALL IS SWITCHED ON AGAIN AFTERWARDS!

    Good luck!

    Hi..
    I have same problem. I bought new macbook - black last week. Internet connection through my wireless router worked fine for 2 days. After that when i started installing updates it net connection is lost even before the completion of updates.
    The wireless signal strength is very good, still no internet. Strange thing is "My torrent client Azuereus works perfectly fine". But I am unable open any website using my safari/firefox.

    I have tried many things like mentioned in this post, restarting in safe mode etc..

    I have no clue why it stopped working.. its really frustrating. I cant even install anymore updates just to see if this issue is fixed by apple recently..
