Do you have internet connection by WAN port of your TP-link? Can you show me Status tab form TP link when you trying internet connection? Do you have some modem from your ISP?

I can't see Status tab!?

Have you been solved problem?

http://uk.tp-link.com/resources/software/TD-W8951ND_V5_141114.zip - this is the latest firmware for your router. I'm not sure but I'm thinking that this firmware doesn't fix your problem. Could you...

System Tools->Time Settings then you can set the time

Sorry I don't know your router hardware version
