Hello, I just changed my router with a new one. It's a D-Link wireless/LAN router. The problem is since using the new router, I can connect to internet using WiFi on my phone and MacBook, but ethernet does not work on Mac at all. When I open the network settings, it displays the ethernet as connected with a green light, but I cannot open any web-pages or ping at terminal. Please help this weird problem is giving me a severe headache. IMPORTANT UPDATE: I can connect to internet via ethernet on the windows 7 virtual machine running on my MacBook. So the problem lies somewhere in OS X configurations and there's nothing wrong with router configs.
