Well, this is getting a bit old, but here is round 3

[MikePerreman]

so, brand new laptop, i installed the update suite, cpp and java plugins, well, surprise surprise, the mdns doesn't work right, i can connect fine over usb and ethernet, if i set the roborio to a static 10.2.47.2, just put that in the ds, and dumping code seems to work ok. but i feel it more of a workaround, not a fix. i am running windows 10, and it would appear that, between windows and dell, its up to date. is there a mdns that im supposed to install as a worst case senerio, or what. this is the 3rd (unique) laptop that has this problem. what have i done wrong?

nevermind, dumping code doesnt work, it gets here:
get-target-ip:
[echo] Trying Target: roboRIO-247-FRC.local
Unknown host: roboRIO-247-FRC.local
[echo] roboRIO not found via mDNS, falling back to DNS
Unknown host: roboRIO-247-FRC.lan
[echo] roboRIO not found via DNS, falling back to static USB
[echo] roboRIO found via static USB
dependencies:
then stalls out, the bot is not connected via USB, only wireless

[AustinShalit]

Using static IP addresses is perfectly fine and plenty of teams use them. If you want to continue troubleshooting the networking over mDNS, please make sure you have done the following:

• Imaged your radio with the latest version http://wpilib.screenstepslive.com/s/...o-for-home-use
• Followed R63 in the 2017 Game Manual
• Restart everything

Is your laptop able to obtain an IP address from the radio?

[MikePerreman]

ok, everything has been updated, i am getting the ip 10.2.47.107, and everything has been restarted. still no mdns. (going to the ds and scanning tells me none found, however putting in 10.2.47.2 connects to the bot)

[MikePerreman]

i dont approve of bumps, but this is urgent

[frodobaggins05]

Do you have a roborio on your robot?

[frodobaggins05]

If so, have you installed labview on your computer?

[MikePerreman]

yes, we have the roborio on our bot, and i have not installed labveiw, we are a java team, so i havent even bothered with that. heres some more info on my situation:
So, our programming mentor and i cannot connect to the RIO over wireless, tethered works just fine, and infact, when tethered, one the tethered is disconnected, we keep wireless comms until you disconnect from the radio, and reconnect. in the DS the 'light' next to robot radio is on. pinging roborio-247-frc.local, on my laptop results in something to the extent of host name not found, and on the mentor's we get a destination host unreachable. however, on the other programming laptop, works first try, every try. ive disabled IPv6 and both mDNS and ni mDNS is allowed through the firewall of my laptop, if a model helps, its a dell inspiron 15.

here is the versions from the DS
DS: 17.0a11
RIO: FRC_roboRIO_2017_v8
Lib: Java 2017.1.1
PCM: 1.65
PDP: 1.40

[MikePerreman]

is there a different board that this thread should be on?

[frodobaggins05]

Try installing labview and using that.Roborio and Labview are both made by National Instruments and are made for each other

[gbear605]

You definitely shouldn't need to install LabView (source: our team doesn't have this issue and doesn't have LabView installed).

Try the following fixes. Any one of them might solve your issue.

Have you tried reflashing the radio firmware (see ScreenSteps for instructions)?

Have you tried a different radio?

Have you tried a different roboRIO?

Have you tried reflashing the roboRIO firmware?

You dont need to use Labview but they work better together and can eliminate a lot of problems

[Fletch1373]

Shot in the dark here... Have you checked whether Windows Firewall is disabled? That is strongly recommended. If you absolutely can't/won't disabled it, you can allow the NI mDNS Responder application through the firewall.

No. Just no. The RoboRio was made by NI for FRC. It was made to support LabView, but most certainly does not require it. FIRST/WPI/et al. work in consultation with NI to get the C++/Java versions working equally as well.

Check in your services to see if mDNS service is running (or if its listed), it should have been installed when you ran the FRC 2017 update suite.

Can confirm that your computer is properly connecting to the router? You should have an IP address like 10.TE.AM.x (You can see this by opening the command line and typing ipconfig)


As a last case scenario, you could try to install iTunes. (I know it sounds crazy) iTunes has apples Bonjor service, another mDNS responder. You shouldn't need to install this though, if you were to I would only use it as a temporary solution to ensure connectivity.

[MikePerreman]

ok, i have installed labveiw, and the bot connects, so long as the rio is the first thing i connect to, however, once i connect to the internet, it can no longer connects to the rio. i do get my ip from the router (most often 10.2.47.107 most often) ive re-flashed the radio and the rio 3 times a piece, we dont have another radio/rio to test at the moment, the ni mdns responder is running and allowed through the firewall, and i have installed bonjior (or however its spells) from itunes.

[MikePerreman]

Aha! if i disconect from wifi, disable my wifi chip, enable, then connect to the bot, it works, however if i disconnect and connect to the internet, i cant connect to the rio anymore.
just turning the wireless off and back on doesnt work
