Wireless Networking Problems

We're having problems with our wireless networking. The classmate looses communication with the robot after aproximently 25 seconds. We have double checked all the settings. The bridge ip:10.26.11.1, the router ip:10.26.11.4, the classmate ip:10.26.11.5, the robot ip is automatically set by the crio imager to 10.26.11.2, and the security is set to wpa-personal, Cypher type is AES, and the passphrase is 2611WPAKEY for both the router and the wireless bridge. For troubleshooting purposes, I hooked up one laptop(10.26.11.6) to our router, and another laptop(10.26.11.7) to the bridge. I then started two command prompts on both computers and started an auto ping(ping /t 10.26.11.X) to both the router and bridge. When the laptop connected to the bridge pinged the bridge, there was 0% packet loss with an average time of 1ms. When the laptop connected to the router pinged the router, it produced the same effect. However, when the laptop connected to the router pinged the bridge, or the laptop connected to the bridge pinged the router, results were intermintant. Here are some of the results(not necessarily in order, this has been going on for several days):
1: Both laptops pinging the opposite device(router's laptop pinging bridge)(robot and classmate disconnected). There would be successful returns 37 times with an average of 2ms, then 7 timeout's. It would then start over.
2: The laptop connected to the router pinging the bridge(robot and classmate disconnected) returned 100% packet loss while the laptop connected to the bridge pinging the router returned 0% packet loss.
3: Both laptops pinging the opposite device both returned 0% packet loss. When robot connected to bridge w/o classmate attached, nothing changed. When classmate connected to router w/o robot connected, nothing changed. When both were attached, it started returning 100% packet loss.
