Jetson Xavier NX hospot unstable

We use the wireless network card in the suite of Jetson Xavier NX , open the hospot connection device for equipment, but the hotspot is not stable that always disconnected, and about a few seconds it will automatic recovery,.We want to ask how can we fix this question?A stable connection is very important to us.
–Details:

  • We have used the voltage regulator module for power supply, at the same time we’ve turned on the intense cooling mode for temperature controling,And none of them showed any problems
  • We use ubuntu18.04 on it and use it to carry camera as well as our robot’s control panel
  • If there is a way to detect the problem and additional information is required, we will fully cooperate

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
Thanks

Sorry for the late response, have you tried to upgrade the network manager to newer version to see if can be improved?
