Connected but no internet (EX6250)

I purchased the EX62050 for a room that my wifi couldnt reach. Now I have full signal throught the house which is awsome, but it won't let me connect to the internet with it.

I did as the instructions said. Plug it into the room with the router till the light turned green. Pressed the wps button on both the extender till it was blinking and on the router. When that light was green I moved the extender to another room closer to the poor signal side of the house, and waited till the signal light turned green.

Sorry if someone posted a answer already I didn't find it, and thank you for any info in advance.
