No need for foxfi to usb tether.
Connect phone to pc with usb, then:
Phone settings > wireless & networks > tethering & mobile hotspots > enable usb tethering.
Bada bing.
Well, that didn't work, I connected the phone, went to tethering and mobile hotspots but usb tethering is grayed out. Any other ideas? Should I just get a wireless adapter?
It went up for me, but the computer said that nothing was connected in terms of the Internet. Is there any settings that need to be done on the computer?
