Dell XPS 13 7390 with Linux
I have a Dell XPS 13 7390 that I have installed Ubuntu 24.04.03 LTS
Been using for a while. I have it connected to a large screen with an old Thunderbolt dockiing station.
I wanted to try to increase my internet speed as I am now using wifi. With Wifi I get about 400 to 450 up and down. On my wired devices I get about 950 to 980.
If I connect to the ethernet port on my thunderbolt docket station it on negotiates at 10mb and thats about all the speed I get. I can connect a 2.5gb USB ethernet device to the other ethernet port and get about 450 down but only 80 to 90 up. Seemingly the upload is being forced to negotiate at 100mb
Any ideas on how to get better speed with ethernet ?
I have updated the firmware of the doc and I assume the laptop is updated -- I ran the apt update and upgrade commands

Hi
Not sure, but the dock is specced at what ethernet?
10/100
10/100/1000
I usually these commands to sort out my Wi-Fi spec...
nmcli -f all device show | sed '/^GENERAL.DEVICE:[ ]\+lo$/,/^$/d; /^AP\[[0-9]\+\]\./d'
inxi-F
inxi -nxxx
ifconfig -a
Unfortunately this Laptop doesn't have an ethernet port, so they may be a waste of time.
It does have a Lenovo USB C to ethernet adapter....
ifconfig -a
