When I try to connect to the robot with my computer via wifi connection the communications and robot code LEDs on the driver station do not turn green
![]() Messages in the diagnostics section are attatched. The settings on the D-Link are as follows: switch set to AP 2.4GHz power is correct CRio plugged in via ethernet cable Camera plugged in via ethernet cable Then I tried plugging straight into the cRIO with an ethernet cable and every 4 seconds or so the message on the diagnostics section of the driver station switched from cRIO(.2)-GOOD to cRIO(.2)-bad When I plugged straight into the DS Radio, via Ethernet cable as well, it didn't improve the connection situation either. I can not see why it does not work ![]() If anyone can help I would be very greatful! Last edited by sarah_storer : 27-01-2014 at 11:20. |

Re: Connectivity Issues
I'd suggest starting with as simple a setup as possible and get that working before adding extra devices into the mix.
That means connecting your laptop directly to the cRIO and debugging that connection first. The obvious things to check are:
Once that's confirmed you can try wireless between the laptop and the DLink.

Re: Connectivity Issues
Have you previously run your robot since your last event that used FMS?
If you have not, I suspect you may have forgotten to reset the security on the radio. If you have, disregard this question. |

Re: Connectivity Issues
I have run it...but I have no idea what you mean by resetting the security

Seeing as the robot has been run since the last event it was at, though, this isn't the issue. |

Re: Connectivity Issues
One of the tools that FIRST gave us this season is the
2013 FRC Bridge Configuration UtilityIf you already have it, then a shortcut was probably added to your desktop. Just connect the DLink to your laptop via Ethernet, run the utility and follow directions. There are also written directions in Getting Started with the 2013 Control System beginning on page 23. or Screensteps: Programming your Radio for Home Use Last edited by Mark McLeod : 08-08-2013 at 09:01. |

Re: Connectivity Issues
Alright I just got into the shop to work on our robot and the wifi started working when I unplugged the camera! I think it has something to do with the IP address or something...I'll look into it.
To the guy that is having connection issues like me: make sure you just start with the basics...if you're having issues try to unplug any accessories (like the camera) from the DS Radio Good luck and I'll keep you all updated! |

Re: Connectivity Issues
To everyone who responded to me, thank you so much. I have gotten wireless communication between the driver station and the CRIO. Unfortunately, I've been working on this from my house using an empty CRIO and a router running off a power outlet, and because I don't have an analog breakout board attached NetBeans won't let me upload code and test it out. I will be getting to a robot on Monday, so I should be able to confirm everything works then.
Here's my new question: how do I change the SSID of the router. I know before the SSIDs on our robots used to be 3958_ROBOT_NAME, but now its just 3958. I imagine this would get confusing when there are multiple robots going at the same time. I have tried putting the IP address into my browser, but chrome is just saying that the webpage is not available. |

Make sure the router is not in bridge mode. If its not, see if a ping works. Also try and reset the router.
