FRITZ!Repeater cannot establish a Wi-Fi connection

After you set up the FRITZ!Repeater, it cannot establish a Wi-Fi connection to the wireless router (for example a FRITZ!Box). The LED on the FRITZ!Repeater flashes quickly for a while and then flashes slowly again.

Work through the following steps to resolve the problem.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Repeater.

1 Installing the latest software for the wireless router

  1. Install the latest software for the wireless router according to the manufacturer's instructions. If you are using a FRITZ!Box as a wireless repeater, proceed as described in the guide Updating FRITZ!OS.

2 Optimizing the FRITZ!Box's Wi-Fi settings

The following steps are only necessary if you are using a FRITZ!Box as the wireless router:

Enabling the 2.4 GHz frequency band

  1. Click "Wi-Fi" ("Wireless") in the FRITZ!Box user interface.
  2. Click "Wi-Fi Network" ("Radio Network") in the "Wi-Fi" ("Wireless") menu.
  3. If you can enable the Wi-Fi networks for the 2.4 and 5 GHz frequency band separately, enable the 2.4 GHz frequency band.
  4. Click "Apply" to save the settings.

Adjusting the name of the Wi-Fi network (SSID)

  1. Click "Wi-Fi" ("Wireless") in the FRITZ!Box user interface.
  2. Click "Wi-Fi Network" ("Radio Network") in the "Wi-Fi" ("Wireless") menu.
  3. Enable the option "Name of the Wi-Fi network visible". This way, all wireless devices can establish a connection to the FRITZ!Box and the FRITZ!Box can optimally control wireless devices in the Mesh ("Mesh Wi-Fi Steering").
  4. If the option "Different names for the Wi-Fi networks on 2.4 and 5 GHz" is displayed, disable this option in order to use the same name (SSID) for both Wi-Fi networks. Only then can the FRITZ!Box automatically steer your wireless devices to the ideal frequency band ("band steering").
  5. Click "Apply" to save the settings. All Wi-Fi connections to the FRITZ!Box are cleared when the settings are adopted.

Disabling the MAC address filter

  1. Click "Wi-Fi" ("Wireless") in the FRITZ!Box user interface.
  2. Click "Security" or "Radio Network" in the "Wi-Fi" menu.
  3. Enable the option "Allow all new wireless devices". If the option is not displayed, enable the Advanced View first.
  4. Click "Apply" to save the settings.

Enabling the WPS function

  1. Click "Wi-Fi" ("Wireless") in the FRITZ!Box user interface.
  2. Click "Security" in the "Wi-Fi" menu.
  3. Click on the "WPS Quick Connection" tab.
  4. Enable WPS.
  5. If available, select the "Push-Button method (WPS-PBC, Push Button Configuration)".
  6. Click "Start WPS" to save the settings.

Disabling the keylock

  1. Click "System" in the FRITZ!Box user interface.
  2. Click "Buttons and LEDs" in the "System" menu.
  3. Click on the "Keylock" tab.
  4. Disable the "Buttons locked" checkbox.
  5. Click "Apply" to save the settings.

3 Optimizing the Wi-Fi settings of the wireless router

The following steps are only necessary if you are using a wireless router from another manufacturer:

Note:Refer to the manufacturer of the wireless router for information on setting it up; for example, consult the manual.

  1. Enable the 2.4 GHz frequency band in the wireless router.
  2. Disable the wireless router’s MAC address filter. You can re-enable the MAC address filter after you have successfully set up the Wi-Fi connection.
  3. If the wireless router supports WPS, enable it. This makes it possible to set up the the Wi-Fi connection from the FRITZ!Repeater at the touch of a button (WPS - Push Button Configuration).
  4. Enable the display of Wi-Fi network names (SSID) and give the router a unique Wi-Fi network name. This way, all wireless devices can establish a connection to the FRITZ!Box and prevents your wireless devices from trying to connect to the wrong wireless router if there are Wi-Fi networks with the same name in the area.

    Note:All Wi-Fi connections are cleared when you apply the new Wi-Fi network name. You must then reconfigure the Wi-Fi connections.
