Single computer - Multiple wifi connection

Question

We have multiple Raspberry pis with wifi dongles.

What we are trying to do is to connect to them all via wifi simultaneously from a single computer so we can issue commands.

Of course, a computer can only have a single wifi connection hence I'm asking this question in case there is a system/technique around that limitation.

I have also looked into having all the PIs on a single network and with unique IP addresses but for this project it's not going to work. That's because each PI is broadcasting it's own wifi network.

Of course, a computer can only have a single wifi connection

No – it can have as many connections as it has WiFi adapters. (I'm not sure whether Windows supports this, but Linux certainly does.) You can install multiple PCI(e) Wi-Fi adapters, and connect even more via USB.

On the other hand, if all networks use the same IPv4 subnet, Linux will require you to set up policy routing to be able to speak over multiple interfaces at once. (This is not required with IPv6, because you could use link-local addresses, or an unique ULA subnet for each device.)
