New Router?
 

Is there a peticular reason FIRST sent us a new Router this year in the veteran kop?

Re: New Router?
 

The D-Link product in the kit is the new robot "radio" and replaces the Linksys gaming adapters used the past two years. There were quite a few communication problems caused with the field and the two previous bridges if things were not brought online in the correct order.

Re: New Router?
 

Like JT said,

Last year the rookies had a newer generation wireless radio on their robots than the veteran teams. Sometimes if all the robots were started simultaneously some would not connect due to conflicts. By giving everyone a new radio this should be resolved.

Re: New Router?
 

So is it meant to be on the robot?

Re: New Router?
 

Yes, it replaces the previous wireless bridge.

If you look at the FIRST control system power diagram notice that there is a power converter (to step down the voltage from 12v to 5v) that you put in between the regulated 12v output and the D-Link device. You run the risk of frying it if you just direct wire it to 12volts

Re: New Router?
 

It replaces both the router and the bridge. Rookie teams did not receive a router. The control system manual available from the KOP website (http://usfirst.org/frc/kitofparts) shows the DAP-1522 being configured as an access point. The DAP-1522 goes on the robot, and the classmate connects directly to it wireless.

Re: New Router?
 

Please pay close attention to this diagram. There are several incorrect ways to wire it that will "work"... until the elimination rounds.

Re: New Router?
 

<R52> One D-Link DAP-1522 is the only permitted mechanism for comunicating to and from the ROBOT during the MATCH.
And...

B. The radio power feed must be connected via the 5V converter (model # TBJ12DK025Z) to the marked 12 Vdc supply terminals located at the end of the PD Board (i.e. the terminals located between the indicator LEDs, and not the main WAGO connectors along the sides of the PD Board). No other electrical load can be connected to these terminals (please see the 2011 Robot Power Distribution Diagram posted online at www.usfirst.org/frc/kitofparts for wiring information).

Re: New Router?
 

I try to follow the manual and when I click setup and then wireless nothing comes up. What am I doing wrong?

Re: New Router?
 

I am having the same issue, I cant get into the new bridge from my computer. I've got the computer set to get the ip automaticaly. When i enter 192.168.0.50 (which is supposed to be the default) into a web browser, it doesnt find it. Pinging doesnt work either.

Re: New Router?
 

To Kgzak,
I can share my experience with that issue, and really what fixed it was changing to internet explorer as the document suggests.(I was initially using chrome) Hope that helps.

To yarb65,
Have you tried resetting your device? Maybe you can give that a shot if its still not working. The instruction to reset are in the document about configuring the radio.

Re: New Router?
 

Guess I have to do it at school then. They don't make Internet Explorer for Macs.

Re: New Router?
 

You missed the step to set the IP address of your computer. Setting it to get the IP automatically doesn't work.

Re: New Router?
 

Is anybody getting the emergency web server page when connected to the router and after having gone to 192.168.0.50? Also, like tons of other people, I am having trouble reseting the router. Any help would be good.

Thanx,

David

Re: New Router?
 

Could you be a little more specific on what kind of trouble you are having with resetting? I followed the instructions exactly as they are and have had success in my first go, my suggestion is maybe you didn't wait for the lights to respond correctly or something of the sort.

Re: New Router?
 

I held the button down for 10 seconds (I think I did it for longer than that), let up, and nothing happened. Little blue power light just kept blinking. Look it up on the D-link website and evidently others are having the same problem. Looked it up on Google and evidently people are having the same problem. I don't know what the "emergency web server" page is about. Some people posted about it on the D-link forum but got no reply.

Thanx,

David

Re: New Router?
 

Did you all change the TCP/IP address on your computer or on the classmate if you did not then you should probably change it to the default that it says in the manual in the section of how to set up a your radio or bridge/router.

Re: New Router?
 

Yep, I did do that. I believe that is when I get the "emergency web server" page.

Thanx,

David

Re: New Router?
 

Could someone please help me? Assistance would be appreciated. Would like to get wireless set up as fast as possible but having problems listed above.

Thanks,

David

Re: New Router?
 

In my experience with wireless networking devices the best way to do a complete hardware reset is the 30-30-30 method.

While plugged in hold reset for 30 seconds, without releasing reset unplug it and wait 30 seconds, without releasing reset plug it back in and wait 30 seconds.

I will dig it out later today and see if I can make a guide and possibly replicate your issues.

Re: New Router?
 

Thanks Trent,
Something else that I get is a blinking blue power light. Hope that helps.

David

Re: New Router?
 

so they way i reset my router was the way you have described above and got the blinking power light, which you are supposed to, and then i waited approx. 2-3 minutes for the lights to all come back on and be steady. Again i followed the directions outlined in the document "How to Setup your Radio" and it worked for me. In fact it was the only document that worked for me. Sorry if that doesn't help. Good Luck.

Re: New Router?
 

In the time it took me to inventory the KOP (I wasn't zooming through it either) the light kept blinking. That's basically all I'm getting. Fixing to contact D-link and see what they say.

Thanx,

David

Re: New Router?
 

D-link fixed it for me. So, no more help is needed. Thanks to everyone who helped. Evidently all I needed to do was download firmware and upload it to the "emergency web browser." Thanks again.

David

Re: New Router?
 

During development, I naively did the power-up with reset because I had a router with an unknown IP. It seemed to wipe the firmware and make it ready to receive a new one. The D-Link reset is documented as holding the pin for 10 seconds with power on, then waiting 30 seconds.

I didn't find documentation stating what a reset during power up was defined to do, but I believe that DLink and Cisco/Linksys have different procedures for factory reset.

Fixing the router that was wiped involved downloading and installing new FW -- slightly annoying at the time, super annoying at an event.

Re: New Router?
 

We are still having issues. We also did the 30-30-30 reset and received the Emergency screen. From there we updated the firmware and were able to get into the bridge. We followed the bridge configuration document and setup the Bridge part first and then setup the Access Point part of the document, saving all changes in the process.

After this setup is complete, we can hook up a wired connection from a laptop, a wired connection from the classmate and a wired connection all to the Bridge, ping all devices and were able to run the Tele-Op and Autonomous Modes (default code) successfully.

All wireless testing is done with the wired connection removed.

With the Bridge in "Bridge Mode", and 1 laptop with windows 7 and the classmate, neither computer can connect wirelessly. The classmate and windows7 laptop do not see the 1208 network at all. The Robot is about 2 feet away from all devices in question. The "Bridge Light" blinks on and off.


With the Bridge in "AP Mode", we get the same results as above. The "Access Point Light" blinks on and off.

Anybody have a clue?

Re: New Router?
 

So we got our wireless working, although it is somewhat of a "hack" (i.e. I would not suggest it unless you are having a lot of problems with your wireless setup). I configured our Bridge in AP Mode to have no security, 2.4 GHz and to act as a DHCP server starting at 10.12.8.10 On our programming laptop I set the TCP/IP to be automatic. On the Classmate I set the NIC Card to Manual Wireless Settings. This allows us full wireless abilities.

The issue is that I do not believe this will be the setup at the competition, and we may run into issues with this at our competition. If anybody sees this as generating problems that I do not foresee please let me know.

Re: New Router?
 

At competitions, the routers will be placed in Bridge mode and programmed with encryption, similar to previous years.

If you want to use bridge mode in your shop setting, you will also need a router which the bridge will bridge to -- the blue router from two years ago would work fine for this.

If you flip the switch between bridge and AP, does it affect settings? I know the router doesn't store two sets of configuration, and it really isn't intended that the user flips it often. It is there so that a single product can work in several configurations, but may require reconfiguration when the switch is thrown.

Greg McKaskle

Re: New Router?
 

You can change the switch and it will act in the respective mode, keeping configurations. If you flip the switch and go into its configuration screen, it will present different options (i.e. in Bridge mode, it doesn't have the ability to be a DHCP server).

I could not get the Classmate to connect to the Bridge when it is in Bridge mode, (and I don't think it's possible). So I assume the FMS system will include a router this year? And we will plug our ethernet connection into it? (i.e. just like last year) There hasn't been much out yet to describe the FMS, besides that they will have a power connection this year.

Re: New Router?
 

My problem is that I can ping the D-link bridge but i cant ping the cRIO. Im sure its conect corretly on the cRio, and the bridge was configurated.

But if i change to the old bridge i can get comunication with no problem.

thanks

Re: New Router?
 

Resetting the router/bridge can be easily done with the use of a pencil and hitting the small button behind the router/bridge. Hold the pencil on the button until the lights start flashing in the front of your router/bridge.

For your emergency web server error: I had no error. I just had some trouble connecting to the bridge itself. The main problem was that my computer's ip address and subnet mask were not correctly set.

So look at your subnet mask and also if there are computers near by: shut them down, because sometimes they can actually accidently connect to the bridge not allowing you to connect.

:)

p.s. the black bridge that we recieved last year burned...I didn't like it's configuration anyway.

Re: New Router?
 

Let me get this straight: veteran teams, even when testing wirelessly, do not need a router?
How does this reconcile with the bridge's default gateway of 10.XX.YY.4, which was (last year, anyway) the router's IP?

Re: New Router?
 

No one, neither veterans, nor rookies, needs more than the DLink.
The DLink in AP mode IS a router. It happens to also ride on the robot.
How simple is that?

In past years during the off-season, many teams replaced their robot radio with the router that came in previous year's Kits. A router that rides on the robot and can communicate on the Classmate's 2.4GHz band (or whatever your driver station laptop wireless band is) is all you need.


The gateway address isn't used until we get to the playing field where the Field Router is at that address (and the DLink's are switched over to act as bridges, not routers).

Re: New Router?
 

Riding on the robot is the part we missed completely. Going back to the drawing board for adjustments.... :eek:

Re: New Router?
 

Hmm. Thanks for the clarification, Mark. That should be very convenient. My team is on the verge of getting that setup working.
