Beim Powerbook meines Vaters das selbe! Schon was herausgefunden?
Ich selber hab mit diversen anderen Mac keine Probleme gehabt.
Bei Books hilft es generell den Akku mal länger als 30min abzunehmen! Das ist letztlich auch nur ein PRAM-Reset, aber im Zweifel gründlicher. Vielleicht hilft das ja!?
oha das klingt nach Neuinstallation!
Tip for anyone with Airport (wireless) problems w/10.5.8 - (Personally I've not seen any 10.5.8/Airport problems with desktops here (5GHz and 2.4GHz networks used here) - but no Laptops/battery powered Macs here currently. And all the N macs I have are Broadcom card based. Some Mac notebooks have used atheros N cards - but not sure that's a factor.)
(from an email yesterday)
"Subject: wifi issues with 10.5.8
I reported earlier of a wifi issue where the computer was having trouble connecting to the 5GHz band.
Looking through the discussions at Apple, the wifi is majorly screwed up on many MacBooks and MacBook Pros depending on the revision of Airport card they have. Some people get no Airport installed, some get really slow downloads and ping times even locally when on Battery but fine on AC power, some get the problem I was having, some get no reconnect after sleep or dropping after 1 hour.
According to some, Apple is working on a fix and it will be in Software Update shortly. In the meantime, anyone having an issue can revert to the previous version of the Airport driver, if they are using Time Machine.
As recommended by an Apple tech, navigate to System/Library/Extensions and then open Time Machine. Travel back in time to before the 10.5.8 update and retrieve IO80211Family.kext and bring it forward.
It'll ask for your password. Then, reboot. You'll get a warning that the kext cache needs to updated, and then after reboot, all should be restored to 10.5.7 wifi glory (which wasn't so great, but better than 10.5.8 for some people). For me, it's now immediately finding the 5GHz network when I wake from sleep, rather than taking too much time and reverting to 2.4GHz or no network at all.
No idea if the update that Apple is due to release will not work after this, so use at your own risk, of course.

Es werden aber nur die o.g. Rechner unterstützt, selbst wenn der Fehler auch bei anderen MacBooks auftritt ...
kann man denn jetzt davon ausgehen, dass das airport patch oder update die probleme behebt?
