My windows 10 did a random restart and now I don't have any options to connect to a wifi source, only a broadband connection??

Hi,

First check on your keyboard if there's any wifi button you can press to activate the wireless card. Next is to install the Wifi adapter, you can download the exact driver for your laptop from the manufacturers support site. If you're wireless card is listed normally in Device Manager right click on it then select uninstall and reboot the laptop that should reinstall it automatically.
