I think the Apple employee was mostly in agreement with you about the amount of RAM. The RAM test was the only of all the extensive proprietary testing he did that failed, but told me it is a matter that the computer was not originally spec'd for that amount that triggers the error. I added the RAM about a month ago, it should have showed up immediately. He recommended an SSD drive in the 'chance' that the RAM is bottlenecking the mechanical drive.
The networking problem is not limited to the wireless network. Even when I reboot the modem and the router, I still can't get my network, not just internet, even when I run an ethernet cable directly into the computer.
This one really has me baffled, then there are the freezes and the magic mouse losing functionality. For now, I am only turning on the computer when I need it and shutting it down again.
