I'd suggest starting with as simple a setup as possible and get that working before adding extra devices into the mix.
That means connecting your laptop directly to the cRIO and debugging that connection first.
The obvious things to check are:
- Turn off any Firewalls or anti-virus that may be running on the laptop
- Fireup the Driver Station app and check that it is allowed to change the IP settings automatically. (See the Setup tab).
- Verify that the team number on the Setup tab is correct.
- After the Driver Station sets the IP addresses, directly verify that they are correct. (Control Panel -> Network Connections -> adapter settings)
- You can also bring up a CMD prompt window and verify your network settings with "ipconfig /all" . Then use "arp -av" to see what shows as connected to your laptop.
Once that works reliably connect via Ethernet through the DLink and that should work identically.
Once that's confirmed you can try wireless between the laptop and the DLink.
- Does the DLink wireless network show up on your laptop's list of available wireless networks?
- Can you manually connect to the DLink SSID from the laptop?
