WiFi problems in windows 7 boot camp
I have the same problem too. I've solved this with updating the driver but with an old driver Broadcom version 5.106.199.1 (11/13/2012). Here is the steps :


Left click on your wireless adapter in Device Manager
Choose "Update Driver Software.."
Pick "Browse my computer for driver software"
Pick "Let me pick from a list of device drivers on my computer"
Choose "Broadcom....Version: 5.106.199.1 [11/13/2012]"
Next.. Wait for installing.. Finish (no need for restart)
