Wireless Connection Problem
Hi gang, I've reseached this question but not found any answers, I hope someone can help.
Our wireless benchtop test has never passed. On previous Cheif Delphi advice, I went ahead and re-imaged the cRIO and DS with the latest loads (steps 5.1, 5.2, 5.3). All that went relativly smoothly. I also went through the wireless adapter configuration in step 5.6. But when I get to step 11 of 5.6.2 where you disconnect the DS router (WRT610N) from the Robot bridge (WGA600N), I get nothing. I’ve read in other posts were the laptop may have automatically turned on encryption which needs to be disabled. I've reconnected the two and ensured the security items are all off or disabled. I also noted that in step 8 c of 5.6.2, the words say set the DHCP field to start at 10, put the associated picture shows 1. Not sure which is correct but neither helped my situation. Also, I can ping the two devices when they are wired together, but when I disconnect the robot bridge, the pings to it go un-answered. Could our bridge be bad? Any ideas? |
Re: Wireless Connection Problem
From my eperience with networks (9+ years), the bridge will be unpingable when connecting from the wireless side, this is due to the fact that it is transparent to all but the wired side when in bridge mode. You should be able to ping the crio though over the wireless connection. I was successful in performing this yesterday.:D Basically the bridge is acting as a media converter, converting a wired transmission media to a wireless transmission media, and vice versa.

Re: Wireless Connection Problem
Scott,
I was able to ping the cRIO while wired, but wireless gives me nothing. |
Re: Wireless Connection Problem
It sounds like the bridge is not connecting to the router over wireless. It could be security, wireless band, or something else. Sending you a PM to help diagnose further.

We had this problem as well. |
Re: Wireless Connection Problem
Sorry Andrew,
I'm not very network savy. Are you saying to "switch the router/bridge to 802.11g/b/n mixed" and then use the lap top's wireless to see if they can be "seen" by it? You mentioned your team had a similar problem - how did you remedy it? Thanks for your help! |
Re: Wireless Connection Problem
We had the same problem and it turns out security was enabled.

The instructions state that the router and the game adapter must be set to 802.11n only. However I decided to modify the router and game adapter to use 802.11b/g mixed instead. After I made that change my laptop connected properly. Let me know if you have any more questions. |
Re: Wireless Connection Problem
i cannot get a signal either. is it frc legal to have the wireless setup to anything other than 802.11n?

Re: Wireless Connection Problem
We were a beta test team. We had this problem with the beta equipment and with our FIRST equipment. The simple answer is after you set up your network ip addresses power cycle everything in order. I don't know why but sometimes the IP address doesn't take until you power cycle the router and bridge.
This is the power cycle order 1 Router 2 Driver station (wait until it boots up) then go to step 3 3 cRIO 4 power up the wireless bridge If powercycling doesn't work it is far quicker to reset the router and bridge back to factory default and start over rather than to try to figure out where you went awry. When you reset to factory default use the included disks do not do it from the web. |

So we do a similar power cycle if stuck in the No-Comm loop. 1 Router/DS (power strip) 2 cRIO / wireless bridge (main battery switch) Most of the time the communication works slowly but surely. The No-comm failures are small but it could be annoying if teams have to wait a minute for the system to startup and then possibly have to power cycle. We are using Update 2.0 default code with 802.11b/g (because we don't have N laptops ) |
Re: Wireless Connection Problem
lynca,
Are you intentionally trying to use your laptop's WiFi radio? Why not disable your laptop's radio and hard-connect to the DS's router? That is, I believe, the technique that FIRST intended. Considering the control system's configuration, maybe there is some difficulty associated with having 3 wireless radios trying to share (eg the system is intended to be ad hoc and not point-to-multipoint).

* The bridge does work when it is wired but not through the DS wireless router. I also tried pinging it and got no response but when wired the ping goes through. So its defiantly something with the wireless signal... - Thanks |
