Can not connect bridge and router wirelessly

[team877]

I can get everthing to work while tetherd but when I try to go wireless it wont connect. I have changed all the IPs to the collect ones..... 10.xx.yy.1 etc and connected all the wires. but still nothing.

Please Help.

if you need a better discription just ask

I doubled and tripled checked all the IP addresses and went through the direction multiple times and still nothing.....when I setup the router and the bridge I hook up the router to the DS and the bridge to the router and then the DS to the computer...I am able to ping them in on a webrowers using the new ip addresses I gave them but once i disconnect the bridge and try to reach it wirelessly I am not able to reach it.

I have no Idea where to go from here

Double check your SSID. If you follow the instructions exactly, you'll set the SSID the router is broadcasting to one ID, and the SSID the bridge looks for as another ID (in your case one will be "frc877" and the other will be just "877"). This could be your problem, you need the SSID on each side to match exactly.

For more info check the presentation FRC 41 gave with FRC 522 here: www.team41robotics.com (on the home page) and here: www.robowizards.com (under "News and Announcements")

When you say that it won't connect. Do you mean from computer(labview) to the cRio or the driver station to the cRio.

If you mean from computer to cRio then make sure that your wireless is wireless N compatible. For that is what FIRST tells you to change all the wireless signals to.

A little off topic, but does anyone know if you change the wireless signal to G will it work like N will. We have laptops to program with, but none of them are N enabled, so programming wireless doesn't work with us.

If you connect to the router via G, it won't affect the N connection from the router to the robot. We've been programming with two computers connected to the router via G without any problem.

This of course brings up the problem at competition...if everyone knows everyone else's IP...what is to prevent shenanigans?

Double heck to see if your security settings are matching up. The only reason I say this is that we had problems connecting wirelessly only to find the DS router had WPA activated (which isn't factory default settings), and a seemingly random password at that. I was there the whole time from opening the box to when our students calibrated the devices and not once did they enter the area where one would activate WPA and set the password. I'm still a little confused about the situation myself.

Just never have your robot connected to the bridge except during matches, do all your programming via cable.
