ELI5: Why can’t our devices simultaneously connect to 2 WiFi networks to provide an even faster internet connection?

Fundamentally there is only the hardware available to talk on one frequency at a time. It can be adjusted to hop between channels but at any given time it needs to be on only one.

Conceptually you could use two sets of antennas and associated hardware to communicate over two separate channels at the same time, but you would need to use the same router to coordinate the transmission of information otherwise you would just be duplicating your effort. At this point we are proposing a heavily modified device on both ends of the process and it probably isn't even helpful because it is rarely the limiting factor in connection speed anyway.
