4. You have gigabit ports connected to a 100 megabit switch (or equivalent device). GBE = Gigabit Ethernet. The 100 megabit will be coming from the speed negotiated with the switch or equipment on the other end of the link. The cat5 cabling is probably not relevant - most cat5 cables will negotiate a gigabit connection (but you might not get ...

I ran my Internet connection through SpeedTest.net which claims that it finds out the actual Internet speed, much lower than that promised by my ISP. But—while downloading—the speed is much lesser than the test results. Even after using download mangers like Internet Download Manager, there isn’t much difference.

To test the maximum bandwidth of a network cable, do the following: Install iPerf on two computers, then connect both to opposing ends of the cable. On one of the computers, start iPerf in Server mode: iperf -s. On the other computer, run iPerf in client mode to test the connection: iperf -c <IP of server>.

Using this script you can easily test connection speed between your machine and some remote host. Example of using: $ scp-speed-test.sh user@remote_host 80000 user@remote_host is your destination host (you must have ssh-access to this host) 80000 is the approximate size of test file (in kbs), which will be received to the remote host. It is not ...

The results I'm getting with speedtest-cli are vastly under what I get from speedtest.net speedtest-cli Download 18.27 Mbits/s Upload 3.43 Mbits/s speedtest.net Download 59.38 Mbits/s Upload 12.14 Mbits/s I can't consider speedtest-cli to be in any way a valid test of network speed. –

Download the version for your OS. On one of the computers run iperf -s (this is the server) and on the other run iperf -c <server hostname or IP> (this is the client). Then wait for the results. There are many options to tweak the measuring. Check iperf -h for a complete list of options. This was a useful reference for me on how to use iPerf ...

To troubleshoot a network problem I would like to inquire the real network"speed" for a given network adapter, which can be seen when opening the"status" of a network connection under Windows: However I want to inquire this over the command line or with a small, separate tool because I need to request this for multiple network connections and don't trust the user to fetch the information ...

You can right-click on the LAN connection and then Check the 'Status'. That will give you the link speed. You can also open a command prompt and run ping.exe to ping other computers on the network. Link speed doesn't reflect the actual speed of the network.

5. I have four devices, Windows 8.1 laptop (mine), Windows 10 laptop, iPhone SE, Android phone, connected to the same network and the Windows 8.1. laptop has a significantly slower download speed (~15 Mbps) than any other device (~100 Mbps for the phones, ~120 Mbps for the Windows 10 laptop). Moreover, I also get very different results ...

Set static IP address for PC A. Set static IP address for WAN port of the Router (your router configuration must support this) On PC A start the server: iperf3 -s. on PC B run the command : iperf3 -c 192.168.2.30 (replace IP as required) The result may look like this (on the sender) when the speed is 95 Mbps: Share. Improve this answer.
