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.
