Is the radio powered by one of the VRM 12v/2a connections? The 12v/500ma connection doesn't supply enough power for the wifi to reliably operate.

Are you reinstalling the firmware & reconfiguring the radio from different PC's, in case it's a PC hiccup?
Do you have last year's radio to try?

It is connected to the proper power connections. Last year's radio still works I believe. We have not tried installing it from different PCs. Is last year's radio legal to use this year?

Yes, last year's radio is legal.

A couple of things to try on the ssh and other connections that aren't working-

(1) On one of the connections that won't work, try connecting to:
roboRIO-2220-frc.frc-robot.local

(2) use IE or Firefox to connect to the roboRIO over USB and see what Ethernet IP the roboRIO was assigned (on the front webpage). Try connecting directly to that IP address.

(3) You can try hardcoding the roboRIO IP address to 10.22.20.2, however you must always have the roboRIO and PC connected through the radio for it to work.


Mark, thanks for the tips. However, we do not have issues connectly wirelessly when using either the Driver Station or the WebDashboard -- both work fine. It is only when trying to download a new RoboRIO program from the Eclipse environment which uses SSH on port 22 under the hood.

We are going to try different firmware tonight to see if it makes any different (2016, and 2017 kickoff -- we are currently using the latest firmware from 1/8/2017 I think).

Re: Connection Issues
 
We have narrowed down this problem to the FRC Radio Configuration Utility (both version 17.0 and 17.2). Whether we check the "Firewall" box or not, TCP port 22 is not allowed through the radio to the RoboRIO. We have discovered how to get around this by logging into the admin interface on the radio (port 22!) and using appropriate configuration commands to add port 22 to the list of ports allowed through.

While this appears to be a bug in the FRC Radio Configuration Utility, I have not gotten confirmation of this as of yet.
