Missing Wifi in iMac 2011 I recently re-built the iMac 2011 by taking it all apart, cleaning and adding new hard disk and fresh install of High Sierra.
I am however unable to get any sort of wifi or even ethernet! This is quite strange! I want to know if there is a way to detect what components are attached to the iMac, like the list of components in Device Manager in Windows?
I want to see if Airport card is detected or not. I double checked the three wirings online as follows and they are attached same way using markings.
The networksetup utility would be a good place to start. (networksetup -help)
