Samsung smart wireless not finding network

Please help, its driving me bananas now. Our Samsung smart tv UE49ES69001 - being working fine - when we first got it, switched on and it picked up the wireless signal immediately with no hassle.

Talktalk have now sent me a new router to upgrade my signal. I took off the Netgear router and put this one on - my desk top Vista and my lap top Windows 7, are both working fine. I had to fiddle with my wireless HP printer but after using the wizard again that also works. BUT my smart tv is saying it cannot find my wireless network.

Can anyone suggest anything to cure this problem please

sorry guys, dont know how to delete question

Just to report after posting my plea for help as above, I rang samung help line. They told me that I needed the MAC and IP for the new router and then enter manually. Back I go to talktalk who tell me that I dont need to enter anything manually as the tv will pick up the wireless. They tell me I need to may be remove the old netgear router details from the tv memory. I go back to samsung as I cant find the netgear details on the tv to remove. I didnt get through though and I just carried on clicking bits on the tv menu. Suddenly the talktalk wireless network is showing - woo hoo - clicked on it, it automatically connected and Im back to square one.

Now, do not ask me HOW - but just to let you know it is working now so that I dont waste anyones time answering. How I wish I knew how it happened though.
