[CentOS-virt] USB passthrough for usb wireless nic adapter

Hi all,

 I am trying to use usb passthrough for an usb wireless adapter to a
kvm guest under a CentOS7 host.

 Guest can connect to an AP and sometimes receives an IP and sometimes
not. But when and IP address is assigned by an AP (and defaultroute),
nothing works. If I try to resolv any host like for example
www.google.com, there is no result ... Trying to ping 8.8.8.8 doesn't
works also.

 Does usb passthrough works for usb wireless nic adapters? Or only for
storage devices?

Many thanks for your help.
