DA100 Gigabit LAN

stst · 01-04-2018, 01:24 PM

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

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:

Code:

$ 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:

Code:

$ ifconfig 
enx9cebe859573b Link encap:Ethernet  Hardware Adresse 9c:eb:e8:59:57:3b

Hi Michael,
do you still read this thread?

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

Code:

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
