Before we can proceed with installing the internet speed test software to Ubuntu, we must first perform a package list update. Installing Any Required Additional Softwareġ. However, one of the most significant advantages of using the official repository is that you will always have the latest software version. This requires a few extra steps as we will need to add the official Ookla repository to our device. This section will show you how to install the internet speed test CLI from Ookla to your Ubuntu device. Installing the Ookla Speedtest CLI to Ubuntu You can open the terminal on the desktop interface by pressing CTRL + ALT + T. The following steps will all be completed within Ubuntu’s terminal. This command line interface will allow us to quickly perform an internet speed test on our Ubuntu device to various servers. Over the following steps, we will show you how to download and install the Ookla Speedtest CLI to Ubuntu. However, if you only had access to the terminal, you would need a different method. If you had access to your Ubuntu devices desktop, you could do this speed test from within a web browser. When your internet feels like it isn’t working as fast as it should be, one of the best ways to check this is by using an internet speed test provider. :-)ītw, I don’t love Ethernet flow control (can cause head of line blocking, etc…), but I do wonder if your switch does not support it (hence why turning it on made no difference).This tutorial will show you how to perform an internet speed test on Ubuntu using the terminal. I don’t think it is a Ziply issue, but I also don’t think you are crazy. Note that I have heard of others having similar issues. It might require some very detailed analysis to figure out what exactly is happening (like hardware tapping devices to see exact traffic flows on the link from your switch to the AP and then to see all the data in the RF stream). Things like which TCP congestion control algorithm is used can also make a difference. Tuning to get a workable Speedtest at 2g or 5g (tcp stack and OS wise) likely results in compromises to results at slower speeds. Ironically, the slower connected Speedtest servers likely are doing better for you as they create a more consistent flow of packets as they are rate limited to one gigabit NIC’s perhaps. When doing local transfers on your lan the rtt is super low and tcp can recover faster from errors. In the upload direction on wifi your PC can buffer data until the WiFi is ready so you don’t have a chokepoint that way. Recovery from packet loss takes time (round trip time). The RF layer is also very bursty (half duplex, depends on interference, other clients, etc…)
The Ont/router/switch your AP is connected to can feed packets to the AP at speeds above what the WiFi RF layer can deliver to the client. This is almost assuredly some form of packet buffering issue.
