Currently have an ax86u. I flashed it with gnouton firmware to see if that would fix this instability issue I have. It somehow made it worse so I am trying to go back to the default but whenever I flash the stock firmware from the Asus site the router will give me an error message and go right back to gnouton. I then tried to reset the thing by holding down the reset button with a pen pushed into it and after it reset it was stock on gnouton. Idk how to go back to Asus default.
