    Hi @Daniel-Ryu ,

    One thing I would recommend doing is setting up the voxl-vision-px4 service using voxl-configure-vision-px4. It's possible that voxl-vision-px4 is in a weird state and this can help reset it and flush out any issues.

    Another thing to check is to turn off all other networks on your PC side of things, i.e. WiFi and any other ethernet connections you may have connected. They can sometimes interfere with things depending on their settings.

    Let me know if this solution helps.

      @tom ran voxl-configure-vision-px4 as per the instructions here and disabled all other networks. No change in situation. Since I can ping from the Flight Deck (using adb shell) to my laptop running QGC, I'm wondering whether the QGC connection service on the Flight Deck can even find the Microhard radio its connected to. Does this sound plausible? Let me know if there are any pictures/screenshots I can upload that would help diagnose this issue.

        This is pretty broadly used, so maybe some configuration has gotten wonky. Can you please share which version of software you are using? https://docs.modalai.com/voxl-utils/#voxl-version

            If it helps, when connected to the flight deck via wifi following the quickstart on m500, my laptop QGC can connect to the flight deck

              Hi @Daniel-Ryu,

              Can you post the output from ifconfig on both your PC and VOXL when everything is powered on.

                      Hi @Daniel-Ryu ,

                      From the screenshots you provided it looks as though your ground control station has the IP address of 192.168.168.108 while in voxl-vision-px4.conf you have it set to 192.168.168.109. It is possible that the IP address of your ground control station changed after a reboot and voxl-vision-px4 is still looking for the old IP.

                      To prevent this problem in the future you should be able to set a static IP for your wired connection on your Ubuntu ground station.
