Set the switch on the back of the DAP-1522 on your robot to "AP." If set up correctly, the D-Link will broadcast your team's SSID and you can connect directly to the robot from your Driver's Station without any extra router. Remember that when you go to competition that switch will need to be set to "Bridge."
You only need to use the black Linksys router if you are running one of your old robots that still uses the square black Linksys Gaming Adapter. Check out
this document starting on page 44.
If you plan on running multiple robots, I suggest that you set your current year's robot to your team number, and previous robots to different team numbers to prevent wireless interference. We have our 2012 robot set as 1610, but our 2011 robot is team 2011 and our 2010 robot is team 2010. Setting the routers/bridges on a different channel will also help prevent interference.
