Cannot communicate with game adapter

[rsisk]

I've read through the many threads on CD about resetting the network for the robot after a competition, have done it successfully several times on different robots, and I follow the directions in the manual each time, but this time I ran into a situation I have not encountered before.

After reseting the network according to the manual, I could not ping the gaming adapter on the robot from the classmate. I could ping the router 10.x.y.4, I could ping the gaming adapter if I ran a cable from the router to the gaming adapter 10.x.y.1. But try as I might, I could not ping it wirelessly.

Now here is where it gets interesting, I had another classmate, so I configured the network on the Classmate 2, identical to the Classmate 1 above 10.x.y.15. I did an ipconfig /all on both computers to compare the configuration and they were exactly the same (except for the MAC address of course). I could plug the network cable into Classmate 2 and ping the gaming adapter all day. Plug the network cable into classmate 1, not able to ping the gaming adapter.

The only conclusion I can come to is a problem with Classmate 1, although I'll be darned if I can even begin to describe what that might be.

Any ideas?
