it asked me to turn on the radio button on the Dell. Do I have a radio button and where is it located
Radio buttons are 'choice boxes' in software. You can turn on / turn off features by choosing between the options.

Good chance the the options you need are in the Networking options in Control Panel.
Did you install a wireless card or dongle in your desktop PC?
Follow the setup instructions that came with your router.
