Prior to doing the router hack, I connected the roboRIO over USB to update firmware, lay down the team-specific image...
Used a little 12V to 5V dc/dc converter to power router on robot. After that I tweaked the old router (turning off dhcp is the main thing):
Got an ancient D-Link DI-524 (T-Mobile-branded TM-G5240) -- this to become GRIO (Gils' roboRIO).
Press-hold Reset until lights off, to restore factory settings.
Turn computer wifi off.
Plug ethernet cable from computer to Port-1 on router.
Browse to 192.168.0.1 (if you use a different router, this all may be different).
- Username admin, password admin.
- Click wireless tab -- radio ON, SSID = GRIO, Chan-6, Open-System, and click Apply.
- Click DHCP tab -- select Disabled and click Apply.
- Click LAN tab -- just leave it at IP = 192.168.0.1, and mask = 255.255.255.0.
- Bridge Mode tab -- should be disabled.
- WAN tab, just leave alone.
Reboot just for grins.
Disconnect cable from computer and connect router Port-1 to roboRIO.
Turn computer wifi on and connect to GRIO.
Can use browser to get to roboRIO Sys Config home page at:
http://roborio-698-frc.local
Or, run DriverStation.
Easy-peasy.
