I have the same problem with this driver:

      urtwn - Realtek RTL8188CU/RTL8188RU/RTL8188EU/RTL8192CU USB IEEE
      802.11b/g/n wireless network device

On this platform:

FreeBSD desktop.example.com 11.0-RELEASE-p9 FreeBSD 11.0-RELEASE-p9 #0 
r316958: Sat Apr 15 09:25:18 EDT 2017 
root at desktop.example.com:/usr/obj/usr/src/sys/GENERIC  amd64

Had to quit using it under FreeBSD works fine in Win7.
