here's my issue I have a wireless/wired cable modem in my mom's house the wireless connect is too weak because of the distance and i need the cable for my desktop. I live in a mini-house behind my mom's place. I passed a 50ft enternet cord in tubing underground to my place so I have a single enternet cable. I'm aware of internet sharing on my macbook pro I use it for my iphone and ipad but my gaming desktop is a PC (it doesn't support wifi btw) any idea how I could get both computers mac and pc online at the sametime? here's my setup to get an idea.
