Yes that is what I imply, most games do the portforwarding for us these days. I will not pretend to know the details of this issue that you had, because I don't. I've only got knowledge from previous issues I've had similar to yours.
The wireless adapters can open ports on the routers in order to do the menial tasks that is portforwarding, my bet is that MWO upon install communicated what ports it wanted to the adapter, the adapter then proceeded to set these. Then upon removal of the old adapters all settings associated with the it was removed, as the new adapter most likely was identified differently by the router.
So a fresh install of MWO, with all traces of the USB adapter removed should fix this?
