kun Posted August 7, 2014 Share Posted August 7, 2014 Hi, Just bought an EliteBook 8470p a month before. I installed Mavericks and work great. Then I replace the wifi module with Broadcom BCM43224 and it work great out of the box on Mavericks. A couple of a week before I installed Yosemite starting from DP1 and my WIFI not working at all. At first I thought maybe Apple didn't update the kext yet. And I keep installing the next DP until DP5 recently using ethernet cable. I had try poking around on IO801 kext with no success. Until I tried comparing my IOReg Mavericks with Yosemite to find out my wifi module not detected at all. Attached is my screenshot of the two IOReg Please help. Thanks!
