Is the Internet not working properly?
To test the speed of a local connection on Linux, you need to install the iperf3 application:
- In the terminal, enter: sudo apt-get install iperf3
- Then we execute the command: iperf3 -p 8082 -c 172.21.4.4 -P 4
- The last values (with the note [SUM]) are the test result.
