Hello CD,
Throughout the 2012 season, our control system has been plagued with lag issues. The first thing we tried was kicking everything except for the cRIO, the E09 classmate running the driver station, and one programming laptop off the network. We were running the the d-link in bridge mode, and connecting it to a separate router. Our lag remained >20ms.
The second thing we tried was using the d-link as an access point. (We never used auto mode) We thought that eliminating the aforementioned router would decrease lag times. However, the lag times jumped off the charts. When we pinged the access point using the classmate, the lag was >1500ms, often loosing 75% of the packets. Interestingly enough, our programming laptop could ping the access point with <10 ms. This lead us to believe that the problem was with the E09 classmate running the driver station. Efforts to use an external USB wireless adapter were in vain.
Both scenarios left our robot undrivable. Am I correct with my diagnosis of the problem, or is it something else? What do you recommend we do?
Thanks,
Daniel D.
