"Your router should be at 10.16.91.1, and your computer should be at 10.16.91.6. 10.16.91.4 is the address that the Wireless Gaming Adapter is supposed to have."
Alan, this information is incorrect, please be careful about this. The Gaming Adaptor is suppose to be a 10.X.X.1 address, the Kit Access Point/Router is suppose to be a 10.X.X.4 address, the robot is 10.X.X.2 and the DS is 10.X.X.5. X.X being the proper team number.
Please refer to the
configuration guide
At the event when a teams VLAN is configured on the field, FMS sets the team's particular SSID to 10.X.X.4, as a respected member of Chief Delphi your information here could have caused a conflict on the field that would have taken an FTA a long time to trouble shoot holding up a regional.
