[AutoBotAM]

I checked numerous times and there is only ever one IP, no excess IPs.

I actually did get the bug to go away, by switching the auto-start Dashboard in Driver Station to LabView, instead of Java, which essentially disables auto-starting SmartDashboard. We just start it manually now.

The bug comes back in the same way sometimes, though, but the problem occurs fairly randomly. Another similar problem that happens at the same time is that the SmartDashboard will not connect to our Axis Camera. I can load the webpage and find that when SmartDashboard is on, the framerate is a lot slower. But sometimes when the wireless is good, SmartDashboard shows the camera, and driver station works normally. I'm pretty sure its just that both programs are fairly intolerant of wireless network underperformance.

So far I have swapped all the ethernet cables, which didn't change anything. I also connected the router and axis camera using their wall-power connectors, problem still didn't change. This eliminates the power source being bad, as well as the ethernet cables being bad. I also connected the laptop directly to the Axis camera via ethernet, and SmartDashboard streamed the camera feed effectively. This suggests a wireless issue to me.

This narrows down to either the laptop or the router. I can't see how the laptop could be the issue since this problem seemed to start randomly (we had the robot sitting on, and the camera feed was going to SmartDashboard normally, but then all of a sudden the camera feed died on the SmartDashboard. We could still access the axis setup page, but the feed was generally slower. This is also when the Driver Station started to misbehave as I've described). Perhaps the laptop has some Windows service that starts routinely and messes some things up, making it seem random, but I doubt it. I think it is most likely the wireless environmental conditions changing and causing network lag, causing Driver Station and SmartDashboard issues.

My next plan of attack tomorrow is connecting the laptop directly to the router via ethernet, with the camera and cRIO connected as well, on the same network. I'll also try swapping connected ethernet ports. If that works, then it would more emphasize either a wireless connection issue, or (possibly) a laptop configuration issue. If it still DOESN'T work, that would suggest an issue in the router itself, which is what I'd prefer not to see. I'll also try using a different laptop. If that works better than the other one, that would suggest a laptop config issue.

Has anyone else here had similar experiences to this? Any advice anyone would like to give so far?
