I have a PC and a laptop (Windows 7 - both) which should connect through router to Internet. The router is Linksys wrt120. My ISP is using PPPoE.
I have connected the Internet cable to the router, clone the MAC of my PC, writing the username and the password for my Internet connection. After seconds the router has acquired IP from my ISP. I have used the administration panel of Linksys and with the help of the ping and tracert commands which are built into it - I can connect to the world, outside the network.
The problem is when I try to connect the PC or the laptop to the network. There's no problem here. The DHCP server of the router gives them appropriate addresses. The problem is that they couldn't connect to either Internet addresses (google.com) or IP addresses. But they can connect to the router and its control panel.
I tried several times, reset the router..but there's no Internet..still.
One more thing: Windows 7 says after a diagnostic: "Your computer appear to be correctly configured, but the device or resource (DNS server) is not responding."
