I just got off the phone with Apple. Random. Out of the blue they call me. They asked me if I had upgraded to 10.7.1 and if the Wi-Fi problem still persisted. I said yes. He asked me if I would be willing to take part in a program to install some special "crash and error reporting software" to help "nip this in the butt." and I said "Yes, I've heard all about it on websites and forums." He paused and said "Oh, I see." I declined and told him that I had downgraded 10.6.8. and understood. He asked me what model computer. I told him and he said "Okay. We'll be in touch. Thank you." Clearly this wi-fi thing is a bit of a problem....duh. (And yes it was Apple. They were aware of how many times I had updated and then downgraded and even saw that I had a file with them going back to a Powermac 6500 I first bought.) Anyone else getting calls?
