Hello,

After many things change.For advance setting need both website setting and mobile app setting. 

  @GeorKhawam 

Are you in router mode or AP mode?

For wireless settings, try disabling smart connect and check it again.

  @QRene 

I've the 2.4 and 5Ghz separately (smart connect disabled).. it don't let me choose the bandwidth MHz individually...  (only in the 2.4Ghz it let me choose 20, 40, 20/40).

Respect to the missing QoS feature, i'm in Router mode 

Setting you want to change are in Moblie app. Website page does not have that setting.

  @TINZ 

When i activate these settings thru Tether App, nothing happens..

For example, in the app i've activated MU-MIMO, fixed 160GHz the channel width and carefully saved the changes... then i entered to the web interface to see, and everything was the same..  then entered the app, and everything was like before:  mu-mimo appeared deactivated  and the channel width was fixed in 80MHz...   it's like my AX73 is doing what it wants (does not obey some orders you select thru the app) 

-In the app:  appears correctly 20, 40, 80 and 160 MHz separately, you can choose one option individually, but when you save changes nothing get saved really... the same with the mu-mimo option...

-In the browser: appears 20/40/80/160MHz  and don't let you choose a only one fixed channel width.. 

I think every time i'm finding more bugs to report by here...

Thank 4 your responses
