lost IP address

[ehn29]

Hi

Do you have any idea why when loading Shredos via an IPXE boot, I lose the network connection.
My client station responds to the ping as long as I am on the Ipxe boot menu.
This problem appears when my client is connected via a network adapter on a USB-C port.
If I use the internal network port, no loss of network.
And therefore at the end of the deletion, no more network to operate the LFTP transfer.

if I manually reconfigure an IP address from the console with ifconfig -a eth0 xxx.xxx.xxx.xxx, I can transfer the log to my server via FTP

thanks
