My guess, it will be months! Do any of the big companies have fully functioning Wifi 6 AP's yet?
"...the folks writing the code for the AP airtime scheduler have a hellaciously difficult job. In the old days, all the scheduler had to do was send out packets using simple methods like round-robin. Now with AX, the scheduler has all the previous methods at hand, plus OFDMA. To complicate the scheduler's task even further, OFDMA also works in the
uplink direction. So the scheduler must also decide if it wants to
receive data simultaneously from multiple STAs. UL OFDMA requires precise synchronization between AP and STA, which, of course, isn't easy. Of course, all these decisions must be made for each transmit opportunity (TXOP). As I said, this is complex stuff."
