so i have a laptop and a PC, i however do not have a cable modem for my PC, but i can hook up wirelessly with my laptop to a nearby router, is it possible to set up internet connection sharing so that i can directly link my laptop to my pc, and use it as my modem. i have tried already and can get the two to share files etc, but haven't been succesfull at all at getting the internet to work,any help would be appreciated, thank you.
