Most of the D-link routers I've used keep a log of DHCP activity. It will
tell you the MAC address of the devices requesting an IP address. If you
have not altered the default settings on your router someone who knows what
they are doing could easily bypass this and you would have no way of
knowing. If you don't understand what the log is telling you I don't know if
I can help you any more than this. It is a very basic log. You have to have
some knowledge of TCP/IP and DHCP in order to understand if someone is using
your WLAN. If you don't have this knowledge there are numerous web sites and
books where you can read up or you could hire a local professional to secure
your WLAN. Some good places to start are here:
