You can still use the 4100 as a host router. What I would do to add wireless so your wireless adapter on the PC will have something to connect too, get you DAP model access point to connect to the 4100, like a DAP-1525, 1522 or 1535. These will be a nice add on to the 4100 and give you wireless broadcast so that your PC will connect wirelessly thru the DAP to the router.
