I had the same mindblowing problem, in my case the autonegotiation was not active (strange but ...):
read "en.wikipedia.org/wiki/Autonegotiation" for more information.
I tried
Code:
# ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supported pause frame use: No
Supports auto-negotiation: Yes
Advertised link modes: Not reported
Advertised pause frame use: No
Advertised auto-negotiation: No
Speed: 100Mb/s
Duplex: Full
Port: MII
PHYAD: 1
Transceiver: internal
Auto-negotiation: off
Supports Wake-on: pumbg
Wake-on: d
Current message level: 0x00000000 (0)
Link detected: yes
then I checked mii-tool
Code:
# mii-tool eth0
eth0: 100 Mbit, full duplex, link ok
as we can see no negotiation.
you can activate the negotiation by simply run
Code:
# ethtool -s eth0 speed 100 duplex full autoneg on
then wait a few seconds because the card now recives the information from the link partner
after a second or two...
Code:
# ethtool eth0
Settings for eth0:
Supported ports: [ TP MII ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supported pause frame use: No
Supports auto-negotiation: Yes
Advertised link modes: 100baseT/Full
Advertised pause frame use: Symmetric
Advertised auto-negotiation: Yes
Link partner advertised link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Link partner advertised pause frame use: Symmetric
Link partner advertised auto-negotiation: Yes
Speed: 100Mb/s
Duplex: Full
Port: MII
PHYAD: 1
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: pumbg
Wake-on: d
Current message level: 0x00000000 (0)
Link detected: yes
and
Code:
# mii-tool eth0
eth0: negotiated 100baseTx-FD flow-control, link ok
now you should be able to talk with other hosts
Code:
# ping 8.8.8.8
PING 8.8.8.8 (8.8.8.8) 56(84) bytes of data.
