Yeh I agree, it's on default settings, another test I did, Passthough mode, which asus call it as as Automaic ip mode, but the prefix don't come at all, so that's why I stay on native
My isp is blaming the router, I've told them, that the router config is fine, I even went from Asus normal frimware to Merlin, did a default factory reset, nothing best I've get it for 1hr 20 min then disappears, I do ping test to Ont modem, it fail...
