It took me a couple of hours to troubleshoot a similar issue with a broadcom ac wlan that came preinstalled on my AW18 after I upgraded to Windows 10. Even though broadcom had released a windows 10 driver package, they included within the package a windows 8 driver that was causing the issue, however it took me several days of BSODs and searching to finally come across a thread that explained what was going on. Since there were no other driver packages for windows 10 for this specific card, I ended up switching back to my Intel 7260ac.
