@xiaoxin Yes I am using the standard web interface, just as I always have.
@alzhao I have already reset it like 10 times. If I make any change, the router goes invisible, and the red light keeps blinking. I have attached the output from the 2 commands you mentioned. The name is currently the default one, since I cannot change it.
Its just like what any normal user would do, changing SSID, password, etc. It used to work flawlessly before, but not anymore. I haven’t made any other change in the hardware or firmware.
