CU200 network card problem

Good morning,

I am experiencing an issue following the upgrade of my installation from build 198 to build 200 (test environment).

Before the upgrade, the system was functioning correctly without any issues. After the upgrade, however, the Wi-Fi network stopped working: the various devices are able to connect but are immediately disconnected. After performing some initial checks, I believe the issue is related to the system not properly assigning the network configuration.

After further troubleshooting, I decided to reboot the system. During startup, the following error message is displayed:

iptables: invalid MAC address specified

I would like to point out that no hardware changes have been made.

I then performed additional checks by running the setup command and discovered that the MAC addresses have changed, as shown in the attached images.
