Device(s) are not reconnecting after reboot of router

[lcalamar]

I am rebooting my Asus RT-AX86U Pro router pretty much daily (due to a connection issue with my wifi brother printer)...

None of my non-mobile devices/tvs are reconnecting... I have to manually reconnect and often - they require I reenter my wifi password.

Since it is occurring on multiple devices (linux desktop, tv appliance, LG tvs...) - I'm wondering what these devices aren't reconnecting - even though they are all setup to autoconnect...

What firmware are you using on the router?
What are the WiFi settings? Post screen shots (redact sensitive information if possible).
Are the WiFi devices connecting to main LAN WiFi or to Guest Network Pro profile WiFi?

No issues using both latest Asus release and latest Asus-Merlin release firmware on a RT-AX86U Pro. My WiFi clients both on main LAN WiFi and Guest Network Pro profiles remain connected including a WiFi HP AIO printer.

Edit to add: Some suggestions.
Some have had to enable the option Disable 11b to fix certain client connection issues.
For the 2.4GHz it is recommended to set a fixed Control Channel (1, 6 or 11) and set Channel bandwidth to 20 MHz. Use WPA-2 Personal or WPA/WPA2-Personal for Authentication Method.
One may also try disabling 802.11ax / WiFi 6 mode if they have compatibility issues.
Try disabling Smart Connect if enabled and configure each WiFi SSID separately.

Agreed with @bennor - suggesting to use wpa2 only instead of mixed. Mixed mode can cause connectivity issues. I had connection issues with my brother Wifi printer (wifi+ethernet) on mixed mode. Setting to wpa2 only and other suggestions above should fix this disconnect with that printer. I've since moved to using the printer on ethernet (media bridge on 5ghz band with WPA3) so as to not use WPA2 encryption anywhere on my network.
