Once, they both blinked at the same time, and stayed for about 3 seconds. Then the robot light turned green too, but it died so fast I wasn't able to test it. Is the bridge dead or what?

OK. From what it sounds like, you're trying to create a WiFi link between the Classmate (or whatever laptop) and the DAP-1522 bridge. In order to do this, the bridge has to be in Access Point mode. I believe the instructions do NOT set it up with way, but I could be mistaken. I this scenario, the bridge is broadcasting an SSID (wireless connection name) so that DEVICES may connect to IT. You also probably need to set a static IP in this situation because the bridge wouldn't be set up for routing.

NORMALLY, for competition at least, you set up the bridge for BRIDGE mode. In this case the BRIDGE is the DEVICE and a main router is the access point. Thus, you would turn off WiFi on your laptop and connect it through a wired connection to the router. Then the bridge would connect to the ROUTER'S wireless network which would then allow your robot and DS to talk (because they're now connected on the same network).

I think you're trying to merge the two situations and the bridge is not connecting to the router because the router isn't even involved. Is this correct? I hope this helps. I may be misunderstanding you situation.

P.S. In the current setup you could possibly set up an Adhoc network with your DS laptop which would then allow the bridge to connect to it as well. You would have to set a static IP for this.
