Can anyone please give a feedback regarding this firmware.
I have a TUF-AX6000 running one of the early firmware due to bugs in the recent ones.
Just wanted to know if the slow/unresponsive pages appear in this release.

IF RT-AX59U TUF-AX4200 and TUF-AX6000 have the "same" hardware why not new firmware avaible for last model?

Now I run TUF-AX6000 as gateway with two RT-AX59U in AP mode... Gateway is a beast, and RT-AX59U I never saw a AP running so cold. I Am impressed
