I was trying to tweak Emule and I screwed up my IP address/LAN thing.(As I said, I'm an idiot when it comes to computers). I can't get on the Net my usual way now. I'm on a different wireless network that has a very weak signal. These are the exact directions I followed from a friend of mine on another site who was trying to help me with Emule.
Port Forwarding: These are settings you need to change in your NAT router. If you don't have a NAT router then you don't need to worry about this. One way to quickly find out if you have a NAT router is to go to Start->Run and type
cmd
if you are on Windows 2000/XP/Vista or
winipcfg
if you have Windows 95/98*DarkIntellect (in which case I recommend upgrading). A command prompt will appear. From there type
ipconfig
It will show you your LAN IP address. If it starts with 192.168. then you definitely have a NAT router. Write this IP address down because you need it to enable port forwarding. To begin configuring your NAT router, goto http://192.168.0.1/ or in some cases http://192.168.1.1/ This is not an Internet site but your router's config screen. One form of port forwarding is called "enable DMZ" which means forward all connections attempts. You just have to enter the LAN IP of the computer you want to receive the connections. If you only want to forward connections to specific ports on specific protocols, use port forwarding. You should be able to configure either one of these options from your router's config screen.
This was where I messed up. I can no longer connect via linksys. For what it's worth, I'm on a laptop. If you need any more info just ask.
