My WiFi connection was suddenly lost and I could not connect to any network. Then it stopped showing available WiFi networks at all! I thought it was a hardware- card failure but then I remembered that I had a BOOTCAMP windows 7 installed, not used for years. I rebooted to windows to find out that WiFi was working flawlessly! Back to OS X does not connect. I have a latest backup in time machine from March 7, can I somehow restore the network settings? I would appreciate any help (besides smc and pram reset, and /library/preferences/files replaced or deleted
)
