Hassio RPi3 IP suddenly changed

Installation Home Assistant OS
1

Hi.
I had my RPi 3 running hassos 2.8, 0.88.0 and connect via wifi
Add-on : Samba share; DuckDNS; SSH server
Everything working well in several weeks already. But today I can’t access
Then I found the IP was change from xxx.xxx.x.xx2 to xxx.xxx.x.xx1
I change the IP then I can access to hassos but the automation is not working

  1. Is anyone have same issue?
  2. How can I change back to the previous IP?
  3. Is any Security concern? (somehow… someone changed?!!)

(^…^) English is my second language so please understand

Did you set a static ip or are you using DHCP?

Thank you for your reply
when setup i used USB with:
“net work” directory
create file “system-connections” and add information with UUID

  '[connection]
id=hassos-network
uuid= my_uuid
type=802-11-wireless'

From my understand it should set my RPi IP as static IP; and last several weeks it worked without any issue

Did you add the static ip config: https://github.com/home-assistant/hassos/blob/dev/Documentation/network.md#static-ip

Or did you leave it on auto?

Ah…
I actually didn’t add, just leave it like that
Should I add to my configuration? Or copy to USB and load from USB?
[ipv4]
method=manual
address=192.168.1.111/24,192.168.1.1
dns=8.8.8.8;8.8.4.4;

Check that the xx1 address is not being used by something else first. If it’s free just use the USB method again.

I did the change in file and “Reload from USB”
Hope it’s solve the problem
I will update later if any changes
