As you can see, using ethtool to force the NIC to only advertise 1000Full and 1000Half causes it to simple advertise nothing. Asking it to advertise everything up to 1000Full causes it to actually advertise only up to 100Full. Nothing interesting via dmesg. # ethtool -s eth0 autoneg off speed 1000 duplex full; mii-tool -v eth0 eth0: 10 Mbit, full duplex, no link product info: vendor 00:d8:97, model 25 rev 1 basic mode: 10 Mbit, full duplex basic status: no link capabilities: 1000baseT-HD 1000baseT-FD 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD advertising: 100baseTx-FD 100baseTx-HD 10baseT-FD 10baseT-HD -- Justin Chudgar | Weed, CA 96094 | 530 921 0738 | http://www.justinzane.com/ -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1063038 Title: Broadcom BCM57780 Cannot Connect at Gigabit Speed using tg3 module.
