Just want to start by saying hi. This is my first post here.

My problem is my macbook(2.0 ghz intel core 2 duo) is showing full signal stregnth in my kitchen, yet everything I try to do says I am not connected to the internet. The funny thing is, my Imac(another intel core 2 duo) which is located on the other side of the house works fine. No internet problems at all.

My router is a D-link rangebooster, which is located in the middle of the house. Also, when the macbook is placed right next to the imac, I still have the issue.

Im sorry if I did not post enough information, I don't know too much about macs, or computers in general. I just want to know what is wrong, since my set up has been working fine for abotu 4 months now. If there was anything I left out, I will post whatever else is needed.
