I've noticed this as well with 802.11g, and both linux and OS X clients 
failing to get a DHCP lease from D-Link routers.  But I think it's a 
problem on Apple's end, and not D-Link.  D-Link uses Cisco PIX for its 
operating system on an ARM7 or ARM9 embedded chip, which is an industry 
standard.  Apple uses something else in the AirPort, and I'm not sure 
what it is.  Usually, when I've seen this problem with a D-Link it's 
because of incompatible encryption settings.  Try using a static 
address on your Mac client and see if that allows the D-Link to 
properly route your packets with NAT.  If that doesn't work, try 
disabling encryption and use straight MAC address filtering to keep 
other people off your network, and see if it fixes it.

If you're familiar with unix command line networking tools you can use 
those to diagnose where the problem is occurring, or use the OS X 
Network Utility, which provides a graphical interface to the unix 
networking tools (found in /Applications/Utilities/)
