Where did you get stuck when choosing the correct device version? Do you remember what was the error message? 

What router do you use? 

For the wifi detection issue, check if the following suggestions help.

1. Does the wifi SSID contain any non-English characters? If it does, try to use English only or a combination of English letters and numbers.
2. If you have a mesh router, try to turn off the mesh nodes, see if the app can detect your wifi in this case. The mesh nodes can be turned on after the camera is set up successfully.
3. Enable a hotspot wifi with another phone, set the hotspot wifi to use the same SSID, password, and security type as the router. Then configure the camera to the hotspot wifi, once it is configured, turn off hotspot and check if the camera can connect to router wifi automatically. Try to restart the camera if it doesn't reconnect automatically.

  @Wayne-TP Hi, I had all the described connection problems and ended up trying all of the actions described.

Ended setting up the camera via Ethernet connection, which made it possible to do a firmware update. But that did not end the problems, what ended the problems for me was a tip from a friend working in IT - rename the wifi/extender to contain only english character etc. no special characters, no spaces, no underscores etc. A simple name on the wifi. This was the magic and the camera found the network.

  @ahle   What elements were used in your original wifi name?
