DA100 Gigabit LAN

[stst]

Hi,

I bought a Dell DA100 to have a Gigabit LAN port on my Inspiron Notebook. This works fine for Windows however in Linux (which is my preferred OS) it connects only with 100MBit/s.
Is there a way to tell DA100 to switch LAN to 1000MBit/s or does the linux driver not support it?

thanks,
Stefan

nobody can answer this question?

The device should give you 1 Gbit speed as it does under Windows. The Ethernet function is driven by kernel's built-in CDC-NCM driver.

What are the details of your setup? Does the device enumerate on USB3 in Linux?

Cheers,
Michal

Hi Michal,

how can I find out?
lsusb gives me:
$ lsusb
Bus 002 Device 004: ID 17e9:436f DisplayLink
Bus 002 Device 003: ID 2109:0210 VIA Labs, Inc.
Bus 002 Device 002: ID 05e3:0612 Genesys Logic, Inc.
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
...


from ifconfig I get:
$ ifconfig

Hi Michael,
do you still read this thread?
thanks, Stefan

In order to find out if it's running with USB 2.0 or 3.0 speed, the easiest way is to use the command
lsusb -t

which, apart from visualising the device tree for USB devices, shows the speed - either 12M, 480M or 5000M - for USB 1, 2, and 3 respectively.

Thanks,
Michal

Hi Michal,

that shows 5000M.
I updated to the latest Displaylink driver now, but network is still running with 100MBit/s

Any other idea?

regards,
Stefan
