10.4: A possible fix for wireless connection problems Network
Tiger only hintWell, much like may other people, ever since I upgraded to Tiger, I have had issues with the AirPort connection on my good ol' Pismo. No automatic connection whatsoever -- on bootup, restart, or wake from sleep. It was really annoying. My home wireless network (DLink WEP protected) would show up, and I could manually connect, but not without human intervention.

I finally found the complete answer: Keychain and Network Preference settings:
  1. In Network Preferences > AirPort, set the "By default, join:" to "Preferred network."
  2. In AirPort > Options..., set "If no preferred networks are found:" to "Keep looking for recent networks."
  3. In Utilities > Keychain Access, select your Network under Login Keychains. Check the "Show password:" box and make sure it is correct -- mine had a "0x" prefix added to it that I had to remove. Under the "Access Control" tab, select the "Allow all applications to access this item." I may be wrong, but I think this is the key to getting all of the automatic connections to work, well, automatically.
I had been able to get partial success with the first two steps, but until I did the third step, nothing was consistent, especially automatic connection at startup. Hope this helps. I would be interested to see if it works with other people's setups.

10.4: A possible fix for wireless connection problems
Authored by: Spartacus on Aug 18, '05 11:42:03AM
I once had to trash file /Library/Preferences/SystemConfiguration/preferences.plist. Another time it didn't help so I dug a bit and wrote an AppleScript to launch with LaunchBar that does only one thing:
do shell script "/System/Library/PrivateFrameworks/Apple80211.framework/Resources/airport -a"
It tells AirPort to automatically connect to the preferred network as it should do when waking up from sleep. I used this script once and then never had to again. Maybe it reset something that had to be or it's just Murphy having fun.

10.4: A possible fix for wireless connection problems
Authored by: visionaut on Aug 18, '05 01:47:31PM

You really shouldn't need to set it so ALL applications can access that Keychain entry. I use just a selected list of the applications that are involved in net access/use, and it works fine.

You're right, all 3 settings are needed for 'always-on' wireless connectivity.

Another problem I've noticed in Keychain is that it's possible for multiple entries of the same app to be listed in the Access List, and some don't have a revision listed, and some do. I remove the dupes and make sure the single entry has the rev showing my installed version. That seems to help too on inconsistent Keychain lookups.

Problem with 'show password' option
Authored by: AssProphet on Aug 18, '05 11:40:25PM

I followed the hint fine up until I had to choose the 'show password' check box. The system asked to Confirm Access to Keychain and required me to enter my keychain password. I typed in the password for my wireless access and it says my password is invalid. My wireless security is set up as WPA Personal or as Linksys calls it a WPA Pre-Shared key (basically any passphrase I choose... no encrypted keys or anything).

I noticed that you ddin't mention having to confirm access to the keychain in your hint... so I'm wondering if perhaps I have something configured wrong with my keychainn permissions or something or if you just left that step out.

Problem with 'show password' option
Authored by: raider on Aug 19, '05 12:44:26AM

You always have to authorize keychain access, unless you specifically turn that off.

The password that it was assking you for was your USER password - NOT the Airport password. Once you put in your user password, it verifies that you do indeed have the correct permissions to see the Airport password, then will show you the Airport password in plain text.

Problem with 'show password' option
Authored by: halt001 on Aug 19, '05 05:07:01AM

The same 'invalid password' happened to me too. I tried the root password, the user password and the wpk password but all were rejected. Unlike other keys where the root password works.

Also my wifi network shows up under 'system' not under login.

Problem with 'show password' option
Authored by: sharakan on Aug 20, '05 04:55:01PM

Same here. I can successfully unlock my "System" keychain directly from keychain access, but the same password does not work when authenticating for the "show password" checkbox. Nor does any other password I tried. This is starting to sound like a bug in Keychain Access. I'm running the latest Tiger bits, BTW.

Problem with 'show password' option
Authored by: wanny on Sep 08, '05 06:55:57AM

I get the same problem, and i think it must be a bug in tiger too. Strangly I can view passwords under the login keychain, using the keychain password (which seems to be the same as my login password). But I can't access my wireless password in the System keychain, which also asks for my keychain password?? Very Weird.

Anyone found a solution for this yet?

thank god there are other people out there with the same problem. It's driving me nuts fighting with keychain and airport logins. I concur, this must be a bug. Now a solution would be good

Add me to your list of frustrated users. Neither my user password or network password will not work.

10.4: A possible fix for wireless connection problems
Authored by: feebdaed on Aug 19, '05 01:29:33AM

This does't fix my problem. Even after trying all of the steps.

Of course I was never able to get my 12" PB to automatically connect, even before Tiger. I definately think there is a problem with DLink WEP.

Yeah I tried my root and user password and both were rejected.
Also just like halt001 my network pasword shows up under system too.

Wireless networks show up under System Keychain (not Login Keychain) for me.

10.4: A possible fix for wireless connection problems
Authored by: wanny on Sep 10, '05 08:22:01AM

I think I've found a solution to the problem of not knowing the system keychain password, which is needed to view the airport network password.

You should be able to delete the airport network password from the system keychain using "keychain access" without any password. I did this the, rebooted the machine and added the information to connect to my wirless network back in to the network pane of system preferences. When I clicked apply, it connected to the network, and I've had no more problems in automatically reconnecting after putting the computer to sleep.

Maybe the password in the keychain was set incorrectly the first time around or something... who knows

Hint works, but why the keychain problem?
Authored by: hintbw on Sep 22, '05 01:15:36PM

Just thought I would add that this hint worked really well for me. I help manage a group of wireless iBooks and we were having a devil of a time trying to get them to auto-connect upon boot or after having gone to sleep (they are being managed via Tiger Server). They wouldn't consistently reconnect without either logging in with the admin account or putting them on ethernet and logging in first.

This hint has now fixed the issue. Thanks a bunch! I'm still curious, however, as to why I couldn't authenticate to the keychain like others had commented. Anybody else have a idea? Wanny's comment about deleting the keychain entry, rebooting, and then reentering it into the network settings worked, but I still would like to know how I can figure out what the keychain password is, since I've tried my admin password and it wasn't it.

Authored by: djjeffree on Mar 16, '06 09:42:41AM

I had the same problem, none of my passwords would work when I tried to authenticate keychain access with either my network password or my uuser password. After I deleted the password in the system keychain i am able to auto connect with no problem.

If I go to system prefs>network>preferred networks and edit my network, if I select "show password" it shows me a new long password that I assume has been created since I deleted the old one. But even if I try to copy this password and retype it in the system keychain it doesnt work. If I change this password, I lose connectivity.

10.4: total fix for airport connection !!
Authored by: mc47mf on Feb 09, '06 04:29:29AM

Hi all,

I don't know if this issue about Airport connection during boot, reboot or resart is over.

But if you have some trouble on auto select a network and it's remain your default network until you change it, even after stop airport, resart your Mac or boot and reboot it, reply to this.

If found the final solution....Just ask me

10.4: A possible fix for wireless connection problems
Authored by: Smokin Jake on Apr 12, '06 04:03:59PM

Often the problem is that when you connect to an Airport network it prompts for a keychain password. Entering here puts it into the Login keychain. This is not where you want it, it must be in the System keychain.

First check if your system keychain is working. In terminal type: SystemKeyChain -vt. If it is not working you will be asked for a passord.
To recreate a new /Library/Keychains/System.keychain in Terminal Type: SystemKeyChain -C

Sometimes the difficulty is because the Wireless Security has changed from WEP to WPA/WPA2.

Open Network preferences -> Airport, by default, join: Preferred Networks. This will give a list of the Airport Networks you have joined with its security. The items in this list will be in the System Keychain. If you see your network here edit it. Check you can show your password. Correct your password / Wireless security.

If you do not see your network add it. Also press Options and Restore defaults, so that when you do sign into a new network it puts the password into your system keychain automatically.

I changed from WEP to WPA2, I could connect, and get internet access but the connection was very very slow, until I changed the security on the Preferred network list. Now its full speed again.

10.4: A possible fix for wireless connection problems
Authored by: aweder on May 29, '06 01:10:39AM

Thanks for this tip, this fixed my 10.4.x reconnection problem after wakeup. I noticed my password was set to $00000000 (tons of 0s following here). I corrected that, now my MP reconnects again.

One slight correction though: when I enter Terminal, I have to use "sudo" in order to execute "SystemKeyChain -vt": "sudo SystemKeyChain -vt" - I have not unlocked the root account. Thus I'm actually asked for a password once in order to execute the command, but am then not asked again, if the access to the system keychain works properly. You'll notice this from the output.

This may help some of you not so fluently on the command line.

10.4: A possible fix for wireless connection problems
Authored by: smkolins on May 29, '06 05:55:33AM

curious! I didn't have to run sudo. I wonder if there are other problems...

I tried to set the system keychain entry to allow the freer access and it
wanted a password to unlock the system keychain which isn't any password
I've put in - yet the terminal command worked as described.

There certainly has been a lot of evolution on the wireless side through Tiger
and into Intel based Macs.
