Issue with Wifi on Raspberry Pi 3B+

Installation Home Assistant OS
1

Hi !!

I’ve some issues with the Home Assistant installation and more precisely about Wifi connection.

My setup:

  • Raspberry Pi 3B+
  • System install on SSD
  • Home Assistant OS 5.10
  • Core Version core-2021.2.0

I’ve followed this website for the Wifi configuration https://techtechandmoretech.com/guides/home-assistant-installation-guide-2020/

My issue is:
My Raspberry Pi connects on my Wifi at the first boot so that’s great, I’ve seen the web page installation process and I’ve created my account and logged in but about 2-3 minutes the Raspberry losts the Wifi connection and I cannot explain why.

I’ve plugged an RJ45 to get an access and in the Supervisor / System / Host the Wifi parameters are correctly configured with my parameters entered in the “my-network” file.

I reboot the Host with Wifi enabled and RJ45 plugged and the Pi get 2 IP addresses reachabled (RJ45 and Wifi) by ping and web access on port 8123 but when I unplug the RJ45 I lost connection on both while the Wifi connection should stay connected …
If I plug the RJ45 back, both connections are UP.

Do you have an idea about this issue?
I’ve already changed the Raspberry Pi, also tried to add a Wifi USB device but that bring me more issues like if I disable the Wifi internal card that’s disable both Wifi Internal and USB…

I’m suffering the same issues since upgrading.

So as you went with a brand new install with same hardware and have same issue with the WiFi dropping.

So your not alone😁

Arf ok, so better install previous version to avoid this?
Any idea of the date fix release?

@fireplex

Did you re-flash and use the “alternatively restore from a snapshot” to recovere from backup?

I tried reflash and snapshot recovery but even then had WiFi problems hence why I believe something is wrong with the new build for rpi3b.

I recovered my whole SD card from backup using win32diskimager

Just wanted to chime in and say I’ve got the same issues here after upgrading last night and then again this morning after restoring my previous setup.

I am having the same issue on a Raspberry Pi 4. I downgraded via ha core update --version 2021.1.5 from the web terminal.
