Question: Crossover Cable can be Dual-Used? Can I use a crossover cable to connect a system directly to another system and/or use it to connect the system to the internet(router)?

Answer: It depends on the kins of router you have. If your router has an 'uplink' button, then you can use cross over or straight through. Chances are that you have a standard home router. In that case, you have to use a 'straight through' cable from the pc to the router. Your crossover cable is mostly intended to conect pc to pc.
