I upgraded to Leopard 10.5.2 on my 24" iMac a couple of months ago after carefully testing that everything worked OK... and it did until today.
This morning Airport began acting-up... connections would be dropped, I couldn't maintain a connection to online radio stations, etc.
When I clicked the Airport icon in the Finder Menu Bar it would indicate that it is "scanning" and then show that it is connected.
Connecting via Ethernet works fine.
A Google search turned up at least two threads at the Apple forums and it appears to be a rather common problem... And I haven't the foggiest notion how to proceed even after reading the threads...
One Thread...Another thread...I have tried disconnecting and reconnecting everything; switched base station channels; switched to a "g only" network; and even tried two Open DNS servers as suggested in one of the threads... No Luck.
Remaining tethered via Ethernet isn't a viable option... my iBook cannot connect because Airport is disabled. Both of my printers are available only via...You Guessed It... Airport. And no more streaming of music to the Airport Express.
I suppose that I could connected the USB printer and cable modem to the iMac, but I would have to disconnect the modem any time I want to use my LaserWriter. And the iBook wouldn't be very usable if I cannot use Airport.
So I am open to suggestions, ANY SUGGESTIONS, up to and including downgrading my OS since I am only partly functional with things the way it is currently...
Seeing as how it is my 54th B-Day (we're having a little celebration this evening... I usually just ignore this day!) I am going to give up for the time being... hopefully when I sign-on tomorrow there will be some Sage Advice awaiting me!
