I am maxing out the (temporary) gigabit connection I am currently using with my EAP783 with my Pixel 9 phone. About 850 Mbps using MLO. My Edge Router and switch is the limitation. When I get all my 10G stuff installed then I will be able to really test the throughput.
With that said I have seen others only getting a maximum of around 1600 Mbps on a Pixel 9 with wifi 7. A good MLO connection should yield 3000 to 4000 Mbps easily. There seems to be some limitations with the Pixel 9’s wifi 7 implementation. Maybe power limitations, not sure.
