There are some settings for the RT-AX88U latest firmware which are missing for the RT-AX89X. I would like to see them added.
For the RT-AX88U, Dual-Band Smart Connect allows setting the Channel bandwidth and Control Channel separately for 2.4 GHz and 5 GHz, as well as configuring the Smart Connect Rule. Also there is a setting for WiFi Agile Multiband.
