Setting up Router and Bridge from Reset

[el-zoroo]

Hey,
After the regional our robot wasn't able to communicate with the classmate. We didn't find out it was an issue with the WPA on the bridge until after we reset both the router and the bridge to factory defaults. We tried to follow the instructions in Chapter 2 of the Control System documentation but to no avail. We tried following the directions numerous times but often we lose connection to the router after updating the wireless security or changing the IP address. As far as we can tell, we've properly set up the bridge.
My question is: is there anything that should be taken into consideration when setting up both the router and the bridge from factory settings? We've followed the instructions in the manual many times and we can never get any communication to the bridge from the router.

Thanks!
