Have Netgear Wireless Router But Can't Find WPA Password

I have reset and rebooted my netgear wireless router. it told me set up was successful yet even though it tells me I am connected I still am unable to access the internet. It also shows an exclamation over my connection bars. How can i fix this? This all started when I was trying to access my router from a new laptop. I could not remember my security key. I reset and erased what I had stored. Have made a new but still no internet access.
