My WiFi connection suddenly went on my Macbook(late 2009) just now and cannot get it to turn back ON?
It was working and then when I picked it up, the WiFi signal suddenly turned OFF. So I went to System Prwferences>Networks and tried the Assistant and then the Advanced mode and I could see that WiFi was OFF. It told me that, I had no WiFi hardware installed. It works with an Ethernet connection but not with WiFi. WiFi would NOT turn ON. Can anyone with experience in the field help me? I am suspecting that my Airport card went.
MacBook, Mac OS X (10.7.5)
