Router has an ip but no internet

Hello,

I'm suffering from a strange issue with my connection for a while, every one or two hours I will lose my internet connection. I tried to change my router, my ISP changed my ip, actually I tried all the common trouble shooting but still facing the same issue. I tried a d-link router, buffalo and now I'm using TP-LINK 900.

When connection drops and I log in to my router, I'm noticing that I have an ip address and every thing must be fine but actually its not because I don't have internet. Even my ISP keeps telling me that you should be connected to the internet while the internet is disconnected.

Many thanks in advance
