Oh i see. He wants to take both his connections, connect them to the router and then connect his both computers wirelessly. Is that correct?
I wouldnt say you should. I would recomment to always have a wired connection with your Desktop computers but if you're using a laptop then yeah use it wirelesly. I dont exactly know if you can connect 2 different connections to a router but i have my DSL connection connected to the router and the router also has 4 wired ports so i have connected 3 computers wired and also i can use my PSP and Wifi Enabled devices whenever i want . I dont have any idea about connecting 2 connections though, i dont think thats possible but i may be wrong.
