I can tether from my smartphone to my laptop via both hot spot and usb cable which is helpful when there is no other option, thought it is not not so fast.
The thing is that I fix relatives' and friends' computers now and then, usually desktops with out wifi capabilities. I do not have a cable long enough to reach my room from where the modem is located. A reasonable solution can be to get a usb receiver but I'm curious to know, is there a way to tether wifi from my laptop to a desktop just like I tether from my phone to my laptop?
I just thought, also, anyone knows a way to tether from a phone to a computer via usb BUT basically resending my houses signal through USB instead of my own phone's 3G?
