Thanks for all the suggestions. We ended up trying to get it to work all last night, and it finally worked right before we left. We reset both the router and gaming adapter to factory defaults 4 times, then followed the instructions in chapter 2 each time. I'm almost certain we did nothing different, but it just happened to work on the fourth time
We did run a power cycle of the router and gaming adapter before our last attempt, but I'm not sure if this is the reason why it worked since this wasn't our first power cycle. We waited for the router to fully reboot, though, before turning the gaming adapter back on.
Hopefully this is helpful to someone.
One last problem we were having: when we tried to connect the classmate wirelessly to the router (following chapter 2), the router's network didn't show up in the list of available wireless networks. I'm not sure what the problem is, does anyone have any ideas?
