Losing WIFI intermittently in use
A coworker had reimaged this laptop (10.11) and when it came up it couldn't connect with an ethernet cable or wifi. It also didn't see flash drives plugged in to the USB. I thought to test it with another system and replaced the hard drive temporarily with a smaller one I installed 10.8.5 onto and everything seemed okay so I gave it back and he was losing connection on the network and wifi again.
These are hooking to 5G Cisco and Ruckus routers in general use in my school district.
Does anyone have a hint these standard wifi cards could overheat and take themselves and other components down?
