We would need to connect to two wifi networks at one with our Nanos. We are already using Intel Dual Band Wireless-Ac 8265 modules in our setup which we very satisfied with both performance and range wise.
So we for the second wifi this module would be a no brainer as we see the Nano could handle multiple PCIe modules so in theory we would be able to a new port in our custom carry board.
What we are not sure of it is there any pitfall what we do not see and we should take into account? Or this could be a viable option in your opinion as well?
