Wifi 7 can communicate with any given station (client) on all bands at the same time, so there’s really nothing to complain about here.
Multi-Link Operation (MLO), a feature that increases capacity by simultaneously sending and receiving data across different frequency bands and channels. (2.4GHz, 5Ghz, 6GHz)
I wonder the same. I can only guess but probably that they don’t update the whole system when installing new stuff.
