I would literally buy all new roku devices for my house if you made a wifi 6 (802.11AX + WPA3) compatible device.
Right now in absence of this, I have to run a dedicated *SLOWER* wifi network in my home specifically to support roku devices.
I just saw new roku devices released without wifi 6. This means any customer you have that buys modern consumer-grade wifi will not have their Roku devices able to connect with their wifi out of box. Specifically because of WPA3 to my understanding more so than the AX standard itself. However, AX is literally purpose designed for video streaming devices. Not sure why its getting slept on.
