We really can't do anything about that, there's no reason on the software side why Wi-Fi would be slower. It has to be down to the connection speed at the physical level.

How slow is it?
You can change the image saving mode to "Leave in the camera" to speed it up.

I agree, Helicon is not at ...

Yes, it is indeed the Access Point mode that works. It is not very fast, but Helicon Remote cannot do anything about that.

Thank you again.

Thank you for your reply.

I ran a quick test and it seems to be working, but I would like some clarification. Is it better to connect the Z50_2 in Station mode or Access Point mode ?

I am unable to connect my Z50_2 to Helicon Remote in Wi-Fi mode (it's Ok in Usb mode), is the Nikon Z50_2 camera compatible with Helicon Remote using the built-in Wi-Fi module?
Thank you in advance for your reply.
