A computer, wireless or otherwise will only have 1 IP address. You'll have 1 gateway IP address via the modem, but each computer or device will have it's own IP address. I have between 5-12 computer/devices running at any given time and each has it's own IP address.

Close, but not quite.
Your router gives each connected device a unique internal IP address that distinguishes different devices on the local network. These addresses are automatically distributed by the router using a protocol called DCHP. Typical IP addresses of local devices might be 10.0.1.1, 10.0.1.2, 10.0.1.3, etc. Some routers may also use IP addresses that use the "192.168.x.x" format, such as 192.168.1.1, 192.168.1.2, and 192.168.1.3.
When you use the Internet, your internal IP address is hidden and only your external IP address is seen by other computers on the Internet. This IP address is provided by your ISP and is assigned to the device that your modem is connected to, which is typically your router. Therefore, all devices connected to the router (whether wired or wirelessly) will share the same external IP address. The external IP address is used to identify your computer to other systems on the Internet. For example, whenever you access a website, the web server can recognize and record your external IP address.
