Problem with wireless
 

I seem to be having a problem with the d-link when I connect wireless, but not when directly wired. I plugged into the d-link (in ap mode) with an Ethernet cable, I was able to configure it's settings. I then changed the LAN ip to connect to the new settings (10.34.13.1 on the router, 10.34.13.51 on my computer). I was able to connect like that. I ran into a problem when I tried to connect wireless though. When I connected wirelessly, I changed my computer LAN address back to default, and changed my wireless ip on adapter 1 to 10.34.13.51. When I connect, it takes a while to connect and then tells me I have limited connectivity. Originally the driver station would say no robot communication and two lights on diagnostic (DS Radio and Bridge) would flash alternatively. When I tried to navigate to the settings page on the d-link, I couldn't connect. Help?

Hi team 3413!

We have the same problem with the d-link AP.
we tried everything and it seems that the wireless of the D-link can't communicate with anything, but if i connect it direct to the laptop with a cable i have no problems to communicate.

If you got a solutions please send me in the mail.

Thanks a lot,

Re: Problem with wireless
 

When Windows tells you "limited connectivity", it just means it doesn't find a connection to the internet.

Re: Problem with wireless
 

If you're able to use a hardwire connection, but the same settings don't work over wireless, I'd start to suspect you either didn't set the radio band properly (for 99% of computers, you'll need 2.4GHz mode) and/or you've enabled some kind of MAC filter on the wireless access by accident.

Can you actually see the wireless access point? Try changing the name a few times and make sure the computer sees the different network SSIDs to confirm you're in the right radio band.

Re: Problem with wireless
 

So far none of these solutions have worked. I understand that limited connectivity means that it doesn't connect to the internet, but I was just posting it in case it affected something. I can see the wireless accsess point. I've changed the name and I can see each different one. I've also reset the router and went by the instructions directly as listed on the radio pdf, and it still does not work. I tried connecting with the classmate from last year, and it got connection. The problem is our reimaging flash drive does not work so I cannot get the 2011 software on it. What can I do to get my personal computer to connect with the robot?

Re: Problem with wireless
 

You don't need the Kit reimaging flash drive to get the new software on your old Classmate.
That Kit flash drive only gives you Windows 7, if you want it.

This year's software comes from the Kit LabVIEW or WindRiver DVDs and the online Software Updates.
You can install them all via any generic thumb drive just like you do for your own laptop.

Re: Problem with wireless
 

Are you referring to the router that we have received in the past years (i.e. not this year)? If so, you cannot use a router along with the DLink in AP Mode. You can use the router if you configure it with the DLink in Bridge Mode. But good luck to this, there has been no official documentation on this procedure and although it is a fairly simple process I have not heard of any teams doing this.

We were using last year's router as a connection for our programming team to our SVN Server. As that router's SSID is "1208" and the DLink's SSID is "1208" if the router is turned on we cannot connect to the DLink with our Classmate. There is obviously a solution to this to enable both functions to work, but the simplest was just to turn off the router when we were using the robot, as we only needed to access the SVN Server at the start and end of the day for backing up software.

Re: Problem with wireless
 

if I understand you correctly, you're saying that we don't need to use the router to communicate with the Dlink with our Classmate. We can communicate wirelessly from the Classmate to the Dlink (can ping it and http to 10.25.23.1), but when we run the driver's station, we never get communication with the robot. the Dlink is connected to LAN port 1 of the Crio, the Dlink is set on AP, and the security has been disabled.
any help would be appreciated!

Re: Problem with wireless
 

Yes that is exactly correct. You should not be using the router. Make sure it is turned off. We had issues where the router would be mistakenly turned on without the programming team's notice and spent about an hour of troubleshooting before we caught this. This has actually happened 3 times.

Can you ping 10.25.23.2? That is the address of the cRIO. If you can, the the issue is with the Driver Station. If you can't, there is another problem (such as a firmware issue). Make sure you set your team number on the DS. If this doesn't work, a fix that we used was to set the connection in the developer mode, and then in the driver mode set it to use a manually configured connection.

Hello this is the programmers from team 2486 we are having trouble with the wireless bridge. the spikes and solenoids we are using start to turn on and off while we are connected to the d-link, and it doesnt matter where we have the bridge. when we use the wireless from last years system everything works fine. so does annyone know what is going on with the wireless bridge.

Re: Problem with wireless
 

we are also having the jaguars going crazy too while connected to the d-link

Re: Problem with wireless
 

Hello teams. team 2486 found that the wireless bridge has issues communicating with windows vista. the bridge communicates with windows 7 properly. we dont know about other opperating systems.

Re: Problem with wireless
 

Hello, I'm from team 1939. We have had the same problem this year and I was wondering if anyone could clarify the network setup that I will crudely try to recreate
Is it cRio-->dlink (new router)---->Classmate---->driver station software
Or is it. cRio-->dlink (new router)--->old router ( configured for last year)----> then so on

Re: Problem with wireless
 

This one.

Re: Problem with wireless
 

cRio-->dlink (new router)---->Classmate & driver station software

Re: Problem with wireless
 

This is sort off topic but does anyone know where I can get the power connectors for the window motors. Or will I have to make them? Plus (This is where I need a lot of responses) Is a victor or a jaguar recommended.

Re: Problem with wireless
 

We bought connectors specifically intended for the window motors, but I have no idea where we got them. There have been reports of jaguars and window motors not mixing well, and admittedly we have had issues with our forklift motor, so I'd try the jags, but don't be surprised if you switch to a victor quickly.
As I understand it, if you don't need the anti-back drive functionality on the window motors (which we do, other wise our forklift would slowly come back to earth) you can remove the locking pins, a process which is described somewhere else. In theory, it will play more nicely with the jaguars then.

Re: Problem with wireless
 

Mainly I think your should redo the setup because it sounds like something is going on in there. also your addressing on the computer from what I can tell its correct but just to be safe. also are you using a crossover or strait when connecting to the router. Im not sure if the Dlink has auto sensing where it doesnt matter but that also could be it.

Re: Problem with wireless
 

So the order is this? > cRio-->dlink (new router)---->Classmate & driver station software?

That would mean that we have to use the computers wi-fi to connect to the dlink? And since classmate doesnt have the capabilities they have the new thing that they give at the competetion. So do we basically just follow the manual to install the new router and then go to the computers wireless communication and connect, without the gaming adapter?

Re: Problem with wireless
 

Kinda going back to the original topic, I think I have found the problem. When I tried pinging the cRIO, no response. Same when pinging the router. But when I checked the ipconfig on cmd, I found that my computer was using ipV6 by default on that connection, and it wasn't overriding with ipV4. I'm gonna check that tomorrow (kinda cutting it close) but I think that may be the solution.

Re: Problem with wireless
 

Er, I think you're saying two different things here ("classmate doesn't have the capabilities... computer's wireless communication"), but to confirm, you use the classmate's built in wifi to connect to the dlink, and you also have your programming computer (if you have one) connect via wireless to the dlink. I'm not sure about the "new thing" at competition you're talking about... care to explain? Or have I not read the rules carefully enough :(

Re: Problem with wireless
 

So the d-link is connected to the C-Rio, and the classmate we only use the wifi of it to connect? Not connect it to the gaming adapter that we had last year? And for that what would be the ips of the computer and the d-link? IS it this: 10.15.14.50 and 10.15.14.51?

This has been answered in other post by Mark but here it is:

At competition (not at home)...

You will take your DLink to a special WPA kiosk to make the event specific settings. These include setting the switch on the back to Bridge mode, resetting the DLink, hooking it up to the WPA kiosk, and the kiosk will supply a WPA security key unique to each team.

When you return home you will return your DLink to AP mode and remove the WPA security set at competition.

Last year's gaming adaptor is not legal for game play in 2011.

At the event for your match, you will plug your driver station laptop into an ethernet cable at the player station.
The Driver Station application will link up with the Field Management System (FMS), and through a VPN unique to your team the field router ill connect to your robot.

Thanks, now i can drive it more than 5 feet! :yikes:
