What wireless USB adapter works with this modem/router?

Hello. I rent my modem from Comcast. Although it is connected to a jack with a coaxial cable, it has a built-in router. It says "dual-band wifi 802.11 ac xb3" on the front of the modem.

I want to connect to the Internet from another desktop wirelessly. The computer does not have a built-in antenna. The Comcast agent told me that I needed a wireless USB adapter on the other computer.

These are easy enough to find, but I don't know what specifications I should be looking for. Could you help me with that?


thnx!
