Re: Help!!! Wi-Fi issues...

You said you are attempting to use the system on your home WiFi system. This will not work.

Most home routers are set up to hand out addresses in subnet 192.168.1.x or 192.168.0.x (a 255.255.255.0 mask). To use the cRio in the way intended for programming, etc, it will need to have an IP address of 10.xx.yy.2, where xx and yy are your team number - quite different from the subnet of your home router. When your laptop tries to send packets to the 10.xx.yy.2 address of the cRio, there will be no path to it in the local network - the router only "sees" addresses inside its own subnet as local, and will fail routing it (it's also possible it will just discard it, depending on configuration, and it's also possible the packets from your laptop won't get anywhere to start with, without a properly assigned gateway in a network configured like this. I'm not a IP expert.)

Namely, the only way to use it in an environment like this would be to directly connect your laptop and cRio (that is, without cutting your internet connection at home, or vastly reconfiguring your router - if it can be, to start with. It sounded like you've done something with an ethernet cable, but I'm not sure what) via an ethernet cable (crossover or not, it should work either way if you have a sufficiently modern laptop). Set your laptop to have the wireless off, and your ethernet adapter with the static IP of 10.xx.yy.6 (as dictated in the guides as normal), subnet mask of 255.0.0.0.

Hope this helps.
