possible, but i'm gonna need to do some weird stuff just to get up there. My mom designed this house, so the walls don't exactly....line up for us. In order to open up a hole between the 1st and second floor, we'd need to take out some drywall, or find a lucky hole. However, that then has to go down 10 feet into the ceiling of the basement, which luckily is unfinished so it's just plywood. There's no interior wall in the room we want to put the computer in that lines up with any interior wall on the 1st floor, so we'd need to do some weird fanagaling in order to drop a line, and if things didn't go perfectly, we'd have a hole in our floor or ceiling or whatever. So I guess what I'm saying is it can be done, but at a great time investment. So in the end, my question remains though...does anyone have specific info on a Cat-5 to coaxial cable adapter or on how to make one? Because while yes, you may be right that might be easier and cheaper to run the line, I would kinda like to make that call for myself. Thanks for the information so far though!
Also, regarding wireless: We already have everything set up for wired, and it's doing fine for us for two years now. We just want to add this ONE computer, so while that may be an option, I wanna just review everything first.
Maybe I should just run the line OUTSIDE my house and in a basement window....
