WiFi Router setup



I just bought a Netgear N300 WiFi Router (WNR2000v5). I access the internet from a wall socket using an ethernet cable. Then, I have to open a browser and sign in to a website with a username and password.
The netgear genie found a "network connection issue: the router cannot connect to the internet with the current settings".
Called netgear telephone line and have been on waiting for 40 minutes. Need help!
