DLink Wireless DSl-2640B

Hi, I got this wireless hub in my office. If I connect to wireless there is not internet connection and if I connect the network cable that's connected to this wireless DLink hub to my laptop I still don't get internet connection. But the funny thing is, if I connect to both at the same time, I get internet connection.


I believe the setup is not right, but cant pickup where I went wrong. Need help here.


Thank you
