Mesh Repeater cannot establish a Wi-Fi connection

After you set up a Mesh Repeater, it cannot establish a Wi-Fi connection to FRITZ!Box. If you are using a FRITZ!Repeater as a Mesh Repeater, depending on the model, the signal strength LEDs flash for a while and then switch off, or the "Connect" LED flashes quickly for a while and then flashes slowly.

To resolve the problem, simply proceed as described below.

1 Installing the latest FRITZ!OS for the FRITZ!Box

  1. Install the latest FRITZ!OS on the FRITZ!Box.

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

Enabling the 2.4 GHz und 5 GHz frequency bands

  1. Click "Wi-Fi" in the FRITZ!Box user interface.
  2. Click "Wi-Fi Network" ("Radio Network") in the "Wi-Fi" ("Wireless") menu.
  3. In the section "Active Frequency Bands", enable the Wi-Fi network for the 2.4 GHz and 5 GHz frequency band.
  4. Click "Apply" to save the settings.

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

  1. Click "Wi-Fi" in the FRITZ!Box user interface.
  2. Click "Wi-Fi Network" ("Radio Network") in the "Wi-Fi" ("Wireless") menu.
  3. Disable the option "Different names for the Wi-Fi networks on 2.4 and 5 GHz". This way, the FRITZ!Box uses the same name for the 2.4 GHz and 5 GHz frequency bands and can steer wireless devices into the frequency band that is ideal in the given situation ("band steering").
  4. 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").
  5. Enter a unique name in the field "Name of the Wi-Fi network (SSID)". This 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.
  6. Click "Apply" to save the settings. All Wi-Fi connections to the FRITZ!Box are cleared when the new Wi-Fi network name is adopted. You must then reconfigure the Wi-Fi connections to the FRITZ!Box.

Disabling the MAC address filter

  1. Click "Wi-Fi" in the FRITZ!Box user interface.
  2. Click "Security" in the "Wi-Fi" menu.
  3. Enable the option "Allow all new wireless devices".
  4. Click "Apply" to save the settings.

Enabling the WPS function

  1. Click "Wi-Fi" 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. 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.
