Hi

Could you please check the following?

  1. Could you also confirm whether the power supply is consistent? Please check the power adapter for any visible damage, and make sure that the wall outlet or extension cord is in good condition.

  2. Which power adapter are you using? Is it the original one, or one that meets the 12V/4A specifications?

  3. Does the ambient temperature range between 40 and 50°C? Or is this the CPU temperature displayed in Admin Panel > System > Overview? If possible, try adding a small external fan to the Flint 2 to enhance cooling.

  1. and 2. yup, i use router’s adapter, check with voltmeter - 12.2 volts without pulses

  2. ambient temp about 23c, I mention thermal_zone0/ system overview value, yes

Please SSH into the router on a wired connected device and run the following command to continuously print system logs and memory usage.
Keep the terminal open, and after the issue occurs, capture and send us the output via private message.

logread -f &
while true; do free -h; echo '-----------------'; sleep 5; done
