Connect to TWO Wi-Fi networks at the same time…

At masking if the macOS will allow the computer to have two simultaneous Wi-Fi connections.

The answer to that question is no. That's what routers are for.

And I agree yours is a question for Sony, or for its documentation.

Edit: Its documentation discusses various connection methods. To accomplish what you seek, do not select this:

[PC Remote Cnct Method] is set to [Wi-Fi Direct]

That would be a peer-to-peer connection. To connect the devices through your existing router or wireless access point, you will want to do the following:

[PC Remote Cnct Method] is set to [Wi-Fi Access Point]

Otherwise use a USB cable.

Without having that camera to play with that's about as far as I can go.

Thank you, but I feel like all of this is getting off track.

I’m really just asking one simple question:

Can the Macintosh connect to two different Wi-Fi sources at the same time?

To be clear I know it won’t do this out of the box, I am asking if I plug-in a USB Wi-Fi card, will it use that card to connect to one and networks, and then the built-in Wi-Fi to connect to another?

Can the OS do this?

The answer is no.

Please be advised a link to a commercial product has been posted to this site. It won't work on your version of macOS.

The specs indicate it supports Bluetooth and WiFi. It also indicates FTP is supported. If Bluetooth does not work for you why not connect the camera to your LAN using WiFi then use FTP to transfer the images?

A direct connection between your computer and camera is similar to the ad-hoc network created by a printer.

There is no conflict between such an ad-hoc connection and your connection to the internet. You do not need another Wi-Fi interface, the you have are perfectly adequate.

I do appreciate your help seeking a solution, but I assure you there’s no other reliable way to connect the camera except via Wi-Fi.

That is why I’m asking if macOS will support to simultaneous Wi-Fi connections. :-)

Then you better contact Sony and let them know their specifications for that camera are incorrect.

Maybe you will get better advice from other similar camera users. Sony likely has a help section on their website. Very few of us in this community would be using that specific camera.

Connect your camera to the computer using Bluetooth if the camera has Bluetooth capability or connect the camera to your local wifi network.

What does the manual say?

You may want to take a look at this document: https://speedify.com/blog/combining-internet-connections/connect-combine-2-wifi-network-connections-mac/.

You don't re-assign your internet connection toward the camera to download camera data.

You generally either look in Finder to see if the camera shows up 'as if it were a drive', or look in Photos App to see if the camera shows up, or run the camera-makers software to 'discover' the camera and download its contents.

Do you have a link to the User manual or a camera-maker's article on how to download your pictures?
