You might check to see if there is newer firmware available for the 
dlink before junking it.

Had some similar issues with an older linksys and a firmware upgrade 
addressed the problem.

If you're really interested in what the dlink is doing, use ethereal on 
the inside and outside edge of the box and see what its doing. Its not 
that hard to figure out.
