Speed of Ethernet connection
The Ethernet connection isn't delivering the full speed you expect. With a 1 Gbps adapter and a cat7 cable, speeds can vary based on network conditions, device settings, or interference. Your internet might be limited by other factors like router performance or bandwidth sharing. Check your internet plan details and ensure your device is configured correctly for optimal performance.
Checking network performance using iperf is a common method. Running a live disk test can help identify whether the problem lies in hardware or software.
Here’s a link to Iperf: https://iperf.fr/ You can use it to compare with Ookla Speed Test results.
Are there additional USB devices linked? Consider switching to a different USB port.
I've connected the USB hub to my ChromBook, using only the USB port on the device. It's tricky because if I start the ChromBook with the hub connected, my keyboard and mouse won't work, and the hub needs to be plugged in for it to recognize it. So I have no option but to use the USB port directly on the ChromBook. I also have a USB keyboard, mouse, SD card adapter, and a USB-C cable attached to the hub.
This situation underscores the challenges with USB-to-ethernet adapters and general USB network devices. Many models reach their performance ceiling despite marketing claims of high speeds. Connecting to a USB 3.0 port usually works well for gigabit connections or full internet bandwidth, but older USB versions can restrict maximum throughput. The internal controller also caps data rates, sharing them across multiple ports at slower speeds. Power consumption becomes an issue as more devices connect, often draining the power from the most used port—typically the first to lag. Chromebooks generally draw less power, so you might already be exceeding your USB port’s capacity. My advice is to either accept these limits, switch to WiFi for better speeds, or use a powered USB hub that supplies independent power. This won’t change the controller’s speed restrictions, but it will relieve the device from excessive power demands.
