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.
