Debug over wireless does not work for CRIO

[dagronlund]

We have been having the following issues with our robot communications. For one when we start to either load java code from Netbeans or try to debug java code from Netbeans, it complains that the computer is not on the same subnet as the robot. We have however set the subnet in windows to 255.255.255.0 and Netbeans reports that it is instead 255.255.255.254. However this issue only causes problems when we are trying to debug in Netbeans, in which case nothing works and the driver station reports that there is no code loaded on the robot. When we instead simply run the code from inside of Netbeans it presents the same warning, but works just fine and the driver station reports that there is code that is working on the robot. Even more interesting is that when we instead perform these same tasks but over wired communications instead of wireless, it does not tell us about subnet errors and both debug and standard execution operate just fine. Any ideas as to what is going on?

Open the network settings and look at the settings. Or if you are more comfortable with it, run ipconfig in a command line.

I suspect you will find that the wired and wireless NIC on your computer are configured differently. If needed, put some of the output on a response so that we can zero in on anything odd in the settings.

Our network settings are set properly according to both ipconfig and Control Panel, but yet Netbeans still reports the netmask incorrectly. However we did try using Java 6 instead of Java 7 and now its reporting the netmask is 255.255.255.255 instead of the old erroneous value of 255.255.255.254 and also that this is the result of a known windows/java bug. Do you know where in the build/debug scripts it looks for the IP address and netmask? Also is there a fix to this windows/java bug?

[dagronlund]

We actually found that the subnet issues could be fixed by disabling the IPv6 connector on the wireless adapter, but we still can't debug because now the debugger is complaining that the connection was refused and then just hangs. Any ideas?

[Mark McLeod]

Have you disabled your firewall?

[dagronlund]

We made sure to disable our windows firewall, but are there any other firewall settings that have to be changed? Also we ran the same stuff on a mac and successfully connected to the robot. Maybe there is some other firewall setting I have looked over?

[Mark McLeod]

There are various other programs that have been known to interfere with communications.

- Disable all other network connections (don't just disconnect). Multiple NICs can confuse the software with too many choices.
- Some anti-virus utilities block communications too, so disable any of those that may be running.
- Some PC vendors add their own software firewalls and such, so disable any of those that might be running.

If I'm not mistaken, the behavior you are seeing is a known issue, with an open artifact in FIRST Forge here. I for one am really hoping this is fixed this year since debuggers are amazingly helpful.

This is an old thread, but I'm having the same problem in 2013.

The short version is:
-Using Wired Ethernet cable, debugging works as expected. The correct netmask is detected by NetBeans.
-Using Wireless, debugging does not work. NetBeans discovers the netmask as 255.255.255.254 (it should be .0). The debugger can attach, but robot code is not run. And no running threads are seen in the NetBeans -> Debugging window.

The configuration:
-Windows 7, Netbeans 7.2.1, JDK 1.7.0_11
-DHCP is running on the DLink WAP, with 255.255.255.0 being used as the netmask. Thus both wireless and wired connections in Windows are getting the same IP configuration. Verified with ipconfig.
-When using wireless all other connections are disabled. "ipconfig /all" displays only one connection.
-In the wireless connection properties, IPv6 has been unchecked. "ipconfig /all" displays no IPv6 connection information.
-Windows firewall has been disabled.
