Wireless options for 2nd system

The reason this would work is that the subnet mask defines what IP addresses the router routes. For example if your routers IP was 10.99.99.4 (team 9999) with the subnet mask of 255.255.255.0 it will only look for devices with 10.99.99.x IP addresses on the LAN ports. If the subnet mask was 255.0.0.0 the router would look for all IP addresses starting with 10.x.y.z.

If you had a router that you could setup with a 255.0.0.0 subnet mask you would be able to setup 2 separate control systems on the same router as long as each control system had individual "team number" IP address sets. The router would just have to have any 10.x.y.z address.
Let me know if you have any questions on this. I would love to explain it more if needed

Actually, the IP/subnet of the router interface is irrelevant to this. The router provided is, functionally, a 6 port switch with one port connected to a wireless access point, another connected to a router/NAT device, and four ports exposed for our use.

Since we are only communicating on a LAN, i.e. on a single switch, router device is never involved in the communications between the DS and the cRio.

You can test this by changing the Ip address of the router to something else. It will still work.

/Explanation

So long as each device has its own IP, which happens if you change you team number, and the subnet masks of the devices communicating(DSs and cRios) match, then it will work.

If you don't read my whole post, if you change the team number on one DS and one cRio, then they will connect and not interfere.

If you have any questions I'll try to explain it more.
