I think in case of networking, you can expose the network facility of
the guest OS, which uses the dedicated USB-Wifi card, via the virtual
NIC provided by Virtualbox. The nic_router component in Genode should
be able to mark the domain of your guest OS to be the uplink for other
domains. With the corresponding routing rules within your guest Linux
you should be able to route requests from other Genode components to
the USB-Wifi card.
Of course, this is a functional solution, but not a favored one with
respect to minimal complexity ;-).

Best regards
