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).
