I've a FRITZ!Box Fon WLAN 7170 Annex A, Firmware version 58.04.57 (latest) and an aluminum iMac 20" and a 12" iBook. Both run 10.5.4, one Intel, the other PPC of course.
Today the iMac stopped connecting to the Fritz, the iBook worked after a few tries. There was a problem with the DSL connection, it would not synchronise, but that's not the issue.
The OSX system.log gives the same errors as seen above, while the Fritz goes:
30.08.08 12:52:43 WLAN registration failed: Authorization failed. Computer name: imac, Mac address: 00:1E:C2:9C:D0:37.
The iMac also seems to fail authentication and time-out. The computers are 20 cm away from one another, so signal strength (which looks perfect) should not be an issue.
Does anyone know if this has been taken up with Apple? Or a solution?
I've ran Onyx on the iMac to clear all system and kernel caches, I've re-typed the password over and over, nothing helps.
I've also seen one other strange thing. The channel list reported in the log does not include channel 12, and sometimes there's an error in the system.log that says channel 12 for FRITZ... is not supported; however the FRITZ's configuration says it's running on channel 1. Bizarre.
Thanks for your input!
