i know using a router is an option, and a better option. However, I am using dialup and so one of my computers is connected to the internet, and I want the other one which is going to be wireless, to connect to the internet through this computer, as I dont think there is an adapter to convert a rj11 standard phone plug to an rj45 which is an ethernet plug. The router I have has only an ethernet port as its WAN input, and I dont know of any way to plug a telephone jack into an ethernet port.
If I have to use internet connection sharing, then do I need to have a disk or something to transfer settings from one computer to the other?
