Changing IP when configuring ssh before installation

[Oleksii Kruhliak]

Decided to reinstall gentoo on my tablet. I usually do this via ssh. Small screen, uncomfortable keyboard. I am using a minimal installation CD image. The connection between the host and the client is via Wi-Fi. There was a problem with the latest image (install-amd64-minimal-20250420T121009Z.iso). The host constantly changes its IP address.
To set up the host after boot, I do the following:
# net-setup
# ip address
# ping i.ua
# passwd
# rc-service sshd start

After this, the host changes its IP address every 3-4 minutes.
How to deal with this. I will be grateful for any help.
Best regards, Oleksii.

Possibly the DHCP server has a very short lease time and doesn't hand out the same IP?

You could make a static lease on the server (likely router) or set a static IP to whichever IP it allocates, but there is a chance it could allocate that to another device at some point.

Using IPv6 local addresses is another option.

Of course, this problem can be circumvented. It is enough to connect via a wired network. In the installed system, this problem is not observed.
The Wi-Fi router settings have not been changed. The tablet's Mac address is assigned a permanent IP address on the Wi-Fi router. But six months ago this problem did not exist. And now I see the third build in which this problem exists.
I don't think this is very good.

Thank you for your attention to my request.

PS: Yes, I forgot to add that IPv6 addresses also change.

Stopping the sshd service does not solve the problem.

Check if NetworkManager is running.
If yes, then use nmtui instead of net-setup.

I just tried to install via minimal iso and observed network manager was running.
