So what's the bottom line? Incompatible with PPOE and DSL? Is this an upgrade to be skipped? Yes? No? Maybe?

On just about every one of these Apple upgraders, someone or more than one macker posts negative comments. Some qualify what they post, some just post that "it sucks and crashes."

These "it sucks, crashes, and destroyed my directory" etc. postings are taken seriously enough that I, for one, will skip the upgrade and wait on the the next. Then the next upgrader comes along and what's the first comment? "It sucks, crashes, and destroys everything." Were there no beta testers? Granted, it's useless to ask anyone from Apple.

To those heros out there who sacrifice their macs to determine that an upgrader "sucks, crashes, and erases everything", how about going to System Profiler and post everything you have on your Mac prior to performing the catastrophic upgrade. Maybe you forgot to unplug all the firewire cables, maybe you have some bizzare PCI card, maybe you're running SCSI. If a particular upgrader is going to hose every mackers directory, at least post how you configured your Mac so we'll know which Macs will be affected. Or, maybe you're 100% right and it crashes every newly bought unmodified Mac!

One more small request - then tell us why Apple's beta testers didn't do their jobs.

Am I asking too much? Look. We're Mac users, not Pee Cee users, just run Apple System Profiler before posting catastrophic comments that must be taken seriously. Negative comments must be taken seriously, at least show the courtesy of describing the circumstances in as much detail as there is.

Thank you, fellow mackers.

Warning! Breaks PPPOE between Airport and ADSL modem. No way to get around it. I'm using a big german ADSL provider and many others report the same problem.

Airport 4.2 updates the base station software to 5.6. As soon as I uploaded this to my base station - it stopped communicating with my PPPoE connection.

The only way I was able to restore internet was to use my wife's PB which had not been updated to Airport 4.2 and using the Airport Admin utility, I uploaded 'default' software to my base station (which took it to 5.5.1) Now it works.

So, at least on my system, Airport 4.2 installs v5.6 of the base station software which does not communicate with my PPPoE connection.

I installed Airport 4.2 onto our iBook G4, 10.3.9 system and now cannot communicate with our Airport (Snow) Base Station: the airport icon in the status bar shows 'no bars'. And, of course, the Airport 4.1 update package will not allow me to roll back to that version since it thinks that Airport is already up to date! Sigh...

No problems here. Also corrected an issue with airport admin not finding my airport express while it was conencted to the internet

i have a powerbook and the AP extreme/express in wpa mode. the ibook of my girlfriend is not able to connect to the wpa2 encryption after the update to 10.4.2 and the 4.2 firmware update. all other hardware works fine, only the ibook g3 900mhz with old airport card bitches...
