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.

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

Posted by jpluimers on 2019/01/21

I have a bunch of [WayBackFRITZ!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

Reminder to self: when your PPTP server is behind a NAT, forward both GRE protocol and TCP port 1723

Posted by jpluimers on 2017/06/06

The WAN sides of my Mikrotik CCR1009 are partly behind Fritz!Box routers that do NAT and contain a truckload of port-forwards.

A while ago, I wanted the CCR1009 to do PPTP as Fritz!Box 7360 and 7490: static routes over VPN don’t work (so I could only VPN to the WAN side of the CCR1009). However, it would not pass through the Fritz!Box from the outside.

It appears you need to forward both:

Maybe one day I will ditch the Fritz!Box 7490 and directly hookup the Mikrotik to the NTU: xs4all ftth en Mikrotik router – Google Groups.

But preferably I should follow Don’t use PPTP, and don’t use IPSEC-PSK either (via: CloudCracker blog)

http://169.254.1.1 trick for Opening UI of the FRITZ!WLAN Repeater 1750E – via: AVM International

Posted by jpluimers on 2015/08/24

Because http://fritz.box points to my Fritz!BOX router, it cannot be used to get to my Fritz!WLAN Repeater. I just learned about the http://169.254.1.1 trick does.

Which saves me from remembering the repeater IP-address or name.
