Enable Ethernet connection

[babyoche]

hello everyone I'm unable to ping this modem
I have been poking around a technicolor cisco modem
via serial console
I belive that the ethernet port is disable or only using ipv6 wich I don't know how to use
I'm trying to ping 192.168.100.10 or 192.168.0.1
I'm trying to download the certs from the modem to the computer like the cert or anything
tftp -r cm_key.bin -p 192.168.100.10
tftp: sendto: Network is unreachable
yes tftp64 is running
D3_1_cm_device_cert.cer     cm_key.bin
D3_1_cm_device_prv_key.bin  mfg_cert.cer
D3_1_device_ca_cert.cer     production.ini
D3_1_root_ca_cert.cer       root_pub_key.bin
cm_cert.cer
this is what I get when I do an ifconfig
