Limit bandwidth with wondershaper

1. Uninstall Debian Wondershaper

This version of Wondershaper is outdated and will not work properly.

sudo apt remove wondershaper

2. Install Wondershaper from GitHub

git clone https://github.com/magnific0/wondershaper.git

cd wondershaper

sudo make install

sudo which wondershaper
This should return /usr/bin/wondershaper if it installed correctly.

3. Configure wondershaper

Note: You can list your network devices with ip addr.

sudo nano /etc/systemd/wondershaper.conf

• change adaptor from eth0 to end1
• set download and upload speeds

4. Enable wondershaper as a systemd service

sudo systemctl enable --now wondershaper.service

Note: If you run into this error:

Job for wondershaper.service failed because the control > process exited with error code.
See "systemctl status wondershaper.service" and "journalctl > -xeu wondershaper.service" for details.

Then you need to change the service executable file location.

sudo nano /usr/local/lib/systemd/system/wondershaper.service

Change /usr/sbin/wondershaper to /usr/local/sbin/wondershaper in ExecStart and ExecStop

Save the file and try to enable the service again.

Wondershaper should now be activated upon reboot.

5. Test changes

pipx install speedtest-cli

speedtest

Note: If you get "ERROR: HTTP Error 403: Forbidden", try running speedtest --secure.
