Fritz!Box repeater and other devices: “Radar detection enabled. At the moment no wireless LAN connection (5 GHz) is possible; please wait.”

Posted by jpluimers on 2021/05/31

If any of your Fritz!Box devices under “Wireless” -> “Radio Channel” -> “5-GHz band”  the indicates “Radar detection enabled. At the moment no wireless LAN connection (5 GHz) is possible; please wait.” – Google Search:

  1. Click on the “Refresh Auto Channel” button
  2. Wait until it has chosen a new 5Ghz channel
  3. Verify you can connect over 5Ghz
  4. If you still cannot connect, retry steps 1…3 once.

I had this only happen on 1750E repeaters so far, but others seem to have had it on other Fritz!Box devices as well.

In the Netherlands, potentially affected channels seem to be 52 through 140.

Using an Fritzbox as DECT-Repeater – PC-WELT

Posted by jpluimers on 2020/04/03

I totally forgot it was possible to usie an old Fritz!Box to act as a DECT repeater:

Um die Abdeckung von DECT für mobile Festnetztelefone zu verbessern, lässt sich eine ältere Fritzbox verwenden.

RP-SMA dummy loads for nonadjustable WiFi devices and Adjust Fritz!Box WiFi power – via Knowledge Base | AVM International

Posted by jpluimers on 2019/07/19

Via [WayBack] Knowledge Base | AVM International:

3 Setting the maximum transmitter power

  1. Click “Wireless” (“WLAN”) in the FRITZ!Box user interface.
  2. Click “Radio Channel” in the “Wireless” (“WLAN”) menu.
  3. If the option “Set radio channel settings automatically (recommended)” is enabled, proceed with the following section.
    • If the option “Adjust radio channel settings” is enabled:
      1. Click “Additional settings”.
      2. Select “100%” from the drop-down list “Maximum transmitter power”.
      3. Click “Apply” to save the settings.
For me, having minimal power was important since every now I needed to be able to connect to it, but only when I was in close proximity.

Hence the settings below: 6% Maximum transmit power is the lowest I could set.

For devices that cannot adjust their antenna output power which have RP-SMA connectors, I bought these to effectively throttle them:

Installing as a LAN -> WiFi bridge: FRITZ!WLAN Repeater 1750E

Posted by jpluimers on 2019/01/21

I have a bunch of [WayBack] FRITZ!WLAN Repeater 1750E | Overview | AVM International devices; this is the quickest way to install them as LAN -> WiFi bridge (connect ethernet to your LAN; use the WiFi as a bridge).

  1. Connect the FRITZ!WLAN to your LAN
  2. Connect the FRITZ!WLAN to power
  3. Connect your laptop to the WiFi SSID FRITZ!WLAN Repeater 1750E with password 00000000 (that eight times a zero)
  4. Set your laptop with a fixed IP address 192.168.178.127 with netmask 255.255.255.0 and gateway 192.168.178.2 for WiFi.
  5. Connect to your FRITZ!WLAN at http://192.168.178.2
  6. Setup your FRITZ!WLAN for the first time (password, country) and have it reboot
  7. Logon to the FRITZ!WLAN
  8. Change the WiFI password and the SSID for 2.4 Ghz and 5.0 Ghz channels (I use a different SSID for both as many Fritz!Box devices have both bad 2.4Ghz performance and a hard time to automatically switch from 2.4Ghz to 5.0Ghz on the same SSID automagically).
  9. Change your laptop to use DHCP on WiFi
  10. Reconnect to the Fritz!Box with the new SSID and password
