<< Thanks. Now my dad is scared I'll tear up the computer. I built mine and upgraded his for him, but he still won't trust me. I put a Linksys NIC in mine and his already had one. His concern is whether we will be able to both be on the internet looking at two different things at the same time. Is there any possibility that I could completely screw up his computer just by networking it? >>
Don't worry. But after you set up the computer to share internet connections, be sure to get a software firewall on all computers to block out any internet traffic. That way, hackers and other people won't be able to trace your computer. Getting the router and hooking up both computers to it will allow you to do both gaming and sharing internet connection. Good luck. Let us know if you have any problems. 🙂
