FRITZ!WLAN Repeater 450E – Service

Since updating FRITZ!OS, wireless connections can no longer be established

Since updating from FRITZ!OS 6.32 or earlier to FRITZ!OS 6.50 or later, individual wireless devices (for example a network printer, Internet radio) that are older can no longer establish a wireless connection (WiFi) to the FRITZ!WLAN Repeater. In this case, the repeater is configured as a "LAN bridge" and makes its own wireless network available. Although the wireless devices can find the repeater's wireless network name (SSID), they do not connect to it after you enter the network key. Newer wireless devices can still connect to the repeater since the update.


  • During the update procedure, the obsolete wireless standard 802.11b is automatically disabled in order to improve wireless performance in the 2.4 GHz frequency band.

1 Enabling the wireless standard 802.11b

  1. Click "Wireless" ("WLAN") in the user interface of the FRITZ!WLAN Repeater.
  2. Click "Radio Channel" in the "Wireless" ("WLAN") menu.
  3. Enable the option "Adjust radio channel settings".
  4. Click "Additional Settings".
  5. Select the standard "802.11n+g+b" from the "Wireless standard" drop-down list.
  6. Click "Apply" to save the settings.

Now you are able to establish the wireless connection again.
