We were having issues with this. These are the troubleshooting steps we went through.
- Ensure that you imaged the roboRIO for your team number.
- Allow UDP port 5353 through the firewall on both inbound and outbound connections.
- Make sure your computer is set to receive its IP via DNS, which is different from last year, when our team used a script to set static IP.
- Try logging into the D-Link web interface at 10.TE.AM.1, with username 'Admin' and a blank password. Click Advanced, then on the left, DHCP. Scroll down to see the list of DHCP clients, and see if the roboRIO is assigned an address.
See if any of these resolve your issue.
EDIT: Additionally, your DLink should be in 2.5Ghz AP mode, not 5Ghz.
