Today I unpacked new Ethernet switch — D-Link DSG-1008D “green” edition. It has 8 GbE ports so I hooked my devices:

  • Linksys WRT54GS
  • desktop with on-board Realtek 8111/8168 card
  • Lenovo T61 with Intel 82566M card
  • Dell D400 with Broadcom BCM5705M card

In theory only router is 100Mbps — rest are 1GbE devices. But not quite… I was unable to get Intel adapter (which use “e1000e” driver) to switch to full speed — it used only 100Mbps speed. Tried ethtool -s eth0 speed 1000 but it refuses 🙁

What was a reason? Wrong cable… I tested all my Ethernet cables and it looks like I am out of real cat5e cables… This will have to wait then until I will end organizing my workplace as there will be rewiring of everything done.

And the Lenovo T61 working on 100Mbps only is not a problem as this machine soon goes back to it’s owner.

    This should all be set to Speed=Auto an Duplex=Auto for GB, for 100MB set both sides to 100MB/FDx.

    Hope this helps 🙂

    @TabTwo: the problem was in Ethernet cable – after switching to other one I got 1GbE out-of-box from e1000e.
