FRITZ!App WLAN Service - Knowledge Base
FRITZ!App WLAN reports "The Iperf server is not enabled"
While the "Measure WiFi" function is being executed, FRITZ!App WLAN displays the error message "The Iperf server is not enabled".
- The wireless throughput measurement fails because the FRITZ!Box is not configured as an Iperf server.
1 Enabling the Iperf server
The wireless throughput can only be measured if the Android device with FRITZ!App WLAN is directly connected to the FRITZ!Box, and the FRITZ!Box is configured as an Iperf server:
- Call up http://fritz.box/support.lua in a web browser.
- Enable the option "Enable measuring point for an Iperf client in the home network, port 4711 for TCP and UDP" in the "Measure Throughput" section.
- Click "Apply Setting" to save the setting.
Now the FRITZ!Box is configured as an Iperf server and FRITZ!App WLAN can measure the transmission rate between the Android device and the FRITZ!Box.
