try going to control panel>network connections>right click on your network and click properties.You should see a box with tabs general and advanced.
There's a box with a scroll thingie right under..scroll down to
Internet protocol [TCP/IP] (see pic at bottom)Click on it and click properties.
You'll get another box that says obtain ip adress automatically and Use the following ip adress.Well click on use the following ip adress and put your ip adress in.It should say it on somewhere on your router page.Like 192.168.2.something. Then click on subnet mask and it fills itself in.Default gateway should be on your router page too. Then below it says preferred dns server and alternate dns server.lol those should be on your router page too.It might say server 1 and server 2 or something else.Mine says dns1 and dns2.
Fill those in then press ok.(pic at bottom)Yes mine says obtain ip adress automatically but i dont know..it works that way for me now.I filled it out before.
