I don't know that particular router, but I would not expect that you can attach a USB wireless adapter to the router and use it as a wireless access point. You probably can attach a wireless USB adapter to your computer and then share the Internet connection from the router Ethernet with the USB device in an ad hoc mode so that phones and other devices nearby can access the Internet, although it requires that the computer be on for it to work. It may be more convenient to buy an inexpensive wireless router and configure it as an AP attached by Ethernet to the current router.
