weird wireless connection problems

[dbeckwith]

We are using the standard D-Link wireless setup with an Eee PC as the Driver Station and having some strange connection problems. When we try to connect to the robot wirelessly, the connection is unreasonably bad. The lights on the driver station flash green and red about every half second and the results from pinging the router give "unreachable" or times in the thousands. What's really strange though is that when we connect to the router from a desktop, the connection seems fine. We also tried connection to other devices and the internet with the Eee PC and the connection was fine. Only the connection between the router and the Driver Station seems bad. When we connect the router to the Driver Station with an Ethernet cable the connection is fine and we can run the robot, but obviously this won't work at the competition. We have another D-Link which we tried yesterday and that seemed to work fine, but today both of our routers have the same problem. We've tried multiple fixes such as checking IP addresses, updating firmware, and checking the power, and that all seems fine, but even if they weren't, it wouldn't explain why only specifically the connection between the Driver Station and router is messed up. Any help is appreciated.
