Hi all,

Some more troubleshooting infos I just gathers from observing the issue:


  - when connecting the Ethernet cable after the reboot process has finished, dmesg on the CPE510 shows eth0: link up (1000Mbps/Full duplex), but the NIC is 100MBit and not 1000MBit. My Laptop show 100MBit when Ethernet connection is establied
  - when connecting the Ethernet cable after the reboot process has finished, ethool seem to have problem to get the Ethnernet device settings:
