Loren, a wifi connection is no different from a network connection.
You can have multiple network connections from a computer. If you
lose the wifi connection because the signal is too weak the computer
will regard it as network cable unplugged.

By adding a USB wifi adapter to your laptop you are adding another
network to the computer. If the USB adapter picks up a wifi connection
the computer will send network traffic down that path.

I once had two internet connections on my desktop. One was connected
to a DSL line and the other to a Comcast cable. My computer sent traffics
down to two paths simultaneously. When I cruised on the web I did not
even know which path the traffic was on. I could disconnect any one
of them. The traffic on it would be switched to the other after a short
delay. I would see a small popup that said network cable unplugged.

BTW, I did have two NIC cards on the PC. One was for the DSL line and the
2nd for the cable modem.
