Since a few days ago my Drobo completly ignores the fact that it can use GBit LAN and uses 100Mbit/Full. What is strange is, that after a reboot it does use GBit but dropps down after a minute. All other Network devices(PC, PS3, PS4) use GBit LAN as they shoud.
“ethtool eth0” outputs:
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Half 10baseT/Full
Advertised pause frame use: No
Advertised auto-negotiation: No
Link partner advertised link modes: 10baseT/Half 10baseT/Full

I tryed “ethtool -s eth0 speed 1000 duplex full” with and without auto-negotioation whitch seems to crash the the networkcard in both cases and I have to reboot the Drobo.
I used my ISP router(can use GBit) and for testing now use a Netgear GBit switch but with the same result
