How can I test the speed of my internet connection?

To perform a speed test, proceed as follows:

  1. Disconnect your router from the power supply for five minutes before the speed test.
  2. Disconnect all devices from the router and use the Ethernet cable to connect your computer/laptop directly to the router.
  3. Restart your computer/laptop and download the Ookla app.
  4. Call up the Init7 speed test server or conduct an Iperf3 test (see nerd mode).
  5. Carry out three measurements. (PLEASE NOTE: WLAN speed tests are not permissible for measurements)

Why am I not reaching the maximum speed of my subscription in the speed tests?

If you are still not satisfied with the speed, please contact our support with all the information and three speedtests.

Speedtest

Countless factors can affect speed negatively. Experience has shown that 99% of all complaints are due to problematic configurations or the user's own applications.

Speedtest.net sometimes suggests unfavourable test servers. Please select only our speed test server (location: Winterthur & Zurich, Init7).

Iperf3 offers an alternative possibility for a speed test:

$ sudo apt-get install iperf3
$ iperf3 -c speedtest.init7.net
$ iperf3 -c speedtest.init7.net -R

iperf3 can be extended by further parameters. -4 resp. -6 specifies whether the test is performed via IPv4 resp. IPv6. Further options via iperf3 --help
