Wireless setup

[Al3+]

I'm having some trouble getting this to work...

I'm following the instructions in Chapter 2 Section 10 of the Control System Manual. This is what I've done:
- Connect the laptop to the router and the bridge to the router
- Set laptop IP to automatic
- Go to 196.168.1.250 and set up the bridge as instructed
- Go to 196.168.1.1 and set up the router as instructed
- Set laptop IP to 10.8.40.10 and try connecting to the router at 10.8.40.4 (works - most of the time)
- Disconnect the bridge from the router and try connecting to 10.8.40.1 (doesn't work)

If I keep the bridge and router connected by cable, 10.8.40.1 connects as expected (except that everything started failing on me after a while and I had to reset both devices and do it again).
Wireless connection from the laptop to the router doesn't work either. I see the network "840" in the list but it fails to connect.

Additionally, before I started messing with it, another team member had set it up for Internet, and both the dev laptop and the Classmate were able to connect to that, whereas neither can connect with the current settings (following the manual).

I struggled with that on our robot for about 3 days.

What finally ended up working was turning off the radio button on the classmate. Apparently it was trying to bypass the router and connect to the bridge directly, which confused everything and everyone involved.

Now that we got it set up, though, we seem to be able to use wireless again, and we're still able to connect to the robot.

Good luck!

We had similar issues.... Updated the firmware on the router and wireless bridge, and all started working.

I think you will find that the router is "helping". It remembers where you attached devices. It then refuses to add a new device with the same address.
We had to power-down the router and disconnect cables. Then when powering on, it would search for new devices.
Sometimes a single power-cycle would fail. We discovered this when we powered up 22 hours later, things worked well!!

Our team has been having the same issues and we updated the firmware and power-cycled the router as reccommended and turned off the classmate's radio. We can get through to the bridge, but we cannot get to it wirelessly. All settings have been configured as directed in the manual. Does anyone have other suggestions for fixing this problem?

Disable the windows firewall and disable the wireless on the classmate PC.

That should fix it.

Hi,
My team is also having trouble setting up our router and wireless bridge to connect wirelessly. We followed the instructions to set up the wireless bridge in the "getting started" section, and then the instructions for setting up the rookie router. When the classmate is wired to the router and the bridge is wired to nothing, I cannot access the bridge from the classmate.
After doing these things, I left the power off on the router and bridge for about 24 hours. Upon setting up the system again, it worked, once. After I restarted the classmate again, though, it stopped working. I have tried turning off the firewall and radio on the classmate when doing this.

My team has not yet connected the bridge to the crio. Could this make a difference?

Does anyone know any other tips for how to make this connection work?

When configuring your wireless router, the configured WIRELESS BRIDGE MUST NOT BE CONNECTED TO THE ROUTER WITH A WIRE (which might be the case if you just finished configuring the bridge). If you leave it connected, as soon as the router setup connects it wirelessly to the bridge, you get a zillion packets flowing around wire cloggig the router's buffer, so it dies and needs to be power-cycled.

There is a problem with the documentation for the 2010 Veteran Team wireless setup. (2009 documentation is OK; Rookie does not have this problem)

Recommended change to 2010 Documentation:

Section 2, page 47, section 2.10.2 Insert Step:
0. Disconnect the Ethernet cable between the WGA600N wireless bridge and the WRT610N wireless router

Note: waiting until step 10 as implied in the documentation only works if you type and click really fast because the buffers start filling at step 6.
