Dell Inspiron N5050 Wireless Driver Not Working

I needed to replace the hard drive on my N5050. After reinstalling windows I am not able to get the wireless driver to install properly. I have a driver disc, which is tells me "A hardware scan has detected the presence of this device" and directing me to which driver I need to install. The disc is telling me I have Dell DW1503 802.11 b/g/n (DW1503 Wireless-N WLAN Half-Mini Card).

However when I attempt to install the driver I get an error message saying that I do not have matching hardware. I'm lost on how to proceed. I am able to connect directly to the internet so I think the network driver is installed correctly.

I can't find the wireless card in the hardware list either...

Any help is appreciated.
