You can connect a PC to a phone via USB and use phone carrier data or wifi internet on which you connect via phone. That option is called USB tethering (sharing your Android device's internet connection via USB), and custom ROMs have it, don't know for stock, that option is in the same place as wifi hotspot. I'm sorry if I understood you wrong, and if this isn't what you were looking for.
