Thanks for answer.

It seems the B5M11WA is the same as the RLC511WA, I did not find any difference.

I was a bit successful. After starting again with factory settings, I now can see the camera-IP in my Fritzbox
WLAN manager.
But I still can not connect. Even Ping is not possible. It's possibly a problem of the Fritzbox settings.

I found how to get factory setting and I started again from the beginning.
This time I just used DHCP setup. Camera is working with LAN so far.

As I tried to switch to WiFi, I found I can not see may own local WiFi network
in the list of networks. Just a lot of the neighborhood.

Could it be that the B5M11WA does not support WiFi 2.4 GHz channel 13 ?
If I change to another channel the network can be seen.

Where can I find something about it?

Thanks

Thank you for the answer.
First problem :
Of cause I tried to save the IP ...1.9 , but it failed. Just I was able to
save the IP ...1.186. But I can live with it.

Second problem:
How I know that WiFi is not working?
I get timeout in Neolink App and in Neolink PC SW (which works with LAN) .
Also the FritzBox WLAN Manger is not aware of the camera.
I removed the LAN cable and turned the camera off and on, of cause, but without
success.
Is there a way to setup factory settings ?

I just got a new B5M11WA with FW version v3.1.01643_22122322.
After DHCP LAN connection I was able to communicate with the camera.
I than tried to use the static IP with xxx.xxx.1.9 . However, I was not able to save this
IP. After changing the IP to xxx.xxx.1.186 , it worked.
Can anybody explain why that happened?

Second problem with WiFi.
Via LAN connection I did the setting for my WLAN Network, but after removing
LAN cable and reset, the camera does not connect to my local network.
Does anybody know how I can verify the WiFi settings via LAN? I just
found in NETWORK all networks names around and my own, but
nothing to setup or verify the settings I did.

Can anybody advice please?

Thank you.
