Netgear wireless router wgr614 v3 connection errors

Hi, techyv experts!
I currently own a netgear wireless router wgr614 v3. I am having problems with its connectivity. I can't seem to access the internet using this router. I really tried following the instructions found on the user's manual. I don't know whether the problem was on how I installed the router or maybe because the product itself was defective. Can you please help me with this problem?
