What I generally do is to make the DLink into an access point that laptops can join wirelessly. This can be done using the radio's config page or the radio configuration tool described
here.
If your laptop supports 5Ghz, use that setting. Some don't, and you'll need to use 2.4 GHz, which can be problematic in certain spaces.
The laptops then need to join the wifi network created by your robot.
If you don't get a connection, you may want to check IP addresses. There are a number of ways to set it up, but I'd recommend using DHCP on the laptop and DHCP on the roboRIO.
