Well I have a usbc hub plugged into my chrombook and the ethernet is in the only usb port on my chrombook. It's complicated because if I boot my chrombook with the ethernet plugged into the hub for some reason my keyboard and mouse do not work and the ethernet has to be plugged in when it is booted for the chrombook to sense it is there so i have no choice than to put in the usb port on my chrombook so i cannot switch usb ports because i only have one on the actual chrombook itself. :(

 

I have a usb keboard, usb mouse, a usb sd card adapter and a usb c cord plugged into the usb c hub

This scenario, unfortunately, highlights the inherent problem with USB-to-ethernet adapters (and USB network adapters in general). Some have hardware that just can’t deliver beyond a certain point, although they still advertise fast speeds.

 

If you’re plugging the adapter into a USB 3.0 port, there should be no problem with obtaining a gigabit link, or at least be able to support your full internet connection. However, this maximum speed is limited if you obviously use legacy USB port versions. Furthermore, the USB controller has a data rate limit, which it has to share among all of its ports, and this is not always at the fastest speed achievable for that standard.

 

Then there comes the problem of powering these devices; the more peripherals you have attached, the less will be available to each. And the one that needs the most to operate correctly is usually the first one to underperform. Chromebooks tend not to be power-hungry devices. I wouldn’t be surprised if you’ve already exceeded the power output of your USB ports based on all the peripherals you already have attached.

 

My recommendation would be to either:

  1. Live with the throughput limitation, or
  2. Use WiFi and hopefully get a faster connection, or
  3. Get a powered USB hub which gets independent power from an outlet. It won’t solve any data transfer limit of the controller, but it will take the power draw load off of the Chromebook.

Is there any reason for ethernet to be at half speed of what I have? So I have 300mb internet at my house. I am useing a cat 7 cable and a ethernet adapter that is rated for up to 1gbs the link is below, why is my internet around 150mbs per second. My chrombook is supports this well over 300mb so I do not know why it is about 150mbs.

How are you testing network speed?

 

Test local network speed with iperf.

 

Did you try running a live disk to see if its a hardware or software issue?

could you give me a link to iperf so i can test

 

I have been useing ookla speed test

Do you also have other USB devices connected?

 

Try another USB port.
