Losing network connection (network unreachable) / load page error / Losing historical data from device

[github4jojo]

The problem

After HA update last week, sometimes I was not able to load the setting page, logbook page or to connect to HA via ssh.
A ping to ha has no answer.
After switch off the Raspberry Pi 5 from the power and switch on to the power, HA is working again.
But after some hours, HA is losing network connection again.
What is the cause of the problem?

What version of Home Assistant Core has the issue?

core-2024.12.2

What was the last working version of Home Assistant Core?

core-2024.11 (maybe core-20204.12.0 was working well)

What type of installation are you running?

Home Assistant OS

The exact same thing is happening to me on raspberry pi 4. I updated to the new HA and my internet works for a while and then after a while disconnects with no access to HA web interface. I need to reboot the pi and then it starts working again.

In the meantime until this is fixed I've installed an android app to my phone called Tasmotrol so I can at least turn my plugs on and off. Also I downgraded back to ha core version 2024.12.0 by going to the terminal and issuing this command: ha core update --version 2024.12.0

I'll see how I get on with that.

Additional information:

1. I was able to solve the network connection problem twice with "ha core restart".
2. Unfortunately, I was unable to copy the error message. The photo of the monitor was too blurry.
3. Last night at 2:46 a.m., HA froze.
4. I was unable to view any logs.
5. After turning the power off and on again, I was unable to find the previous error message on the monitor in home-assistant.log and home-assistant.log.1. Have they all disappeared, or can they be found somewhere else?

It seems to me that the problem is with the network connection in the core. An error message from a Python program was visible there (I have connected a monitor to the Raspberry Pi 5).

I've gone back to the latest stable release in november and haven't had any issues since. I hope this issue can get sorted out.

Are you using the original power supply from the Raspberry?
I get an error message because a voltage drop was detected.
Today I replaced the power supply (GeeekPi Raspberry Pi 5 power supply 27W 5.1V 5A USB C power supply) with the original.
So far i can see, no more error messages.
The latest version for today is also running without any problems.
Core 2024.12.4
Supervisor 2024.12.0
Operating System 14.1.rc1
Frontend 20241127.8

It seems to me that the problem is gone now.
No "Undervoltage detected!" message and no freezing!
We can close this issue.
