    Hello,

    My RTN56U has been working perfectly for about 3 years. I, recently, did a reboot from the web interface and the router did not come back up.

    Upon inspecting the router, I saw that the power LED blinks slowly which made me think that it's stuck in rescue mode.

    I tried rebooting it again and it still went back to the slow blinking power LED.

    Thinking that the issue may be an opportunity to upgrade to the latest firmware, I did the typical reset button + power on.

    When trying to flash the firmware, the utility kept indicating after 30 seconds with a message "The wireless router is not in rescue mode". This continued for a few hours.

    I started reading up some threads on snb and also tried the 30-30-30 method as well as using the wps method.

    I finally reached a point where I tried to check if I am able to ping the router interface (192.168.1.1). To my surprise, I wasn't able to do so. To say the obvious, I'm connecting with the LAN port of the router that is hooked into a LAN port of a laptop. The laptop is configured with a static IP in the same subnet. The cable is fine as I am able to use the same cable for other purposes. I have also tried and stopped windows firewall/defender. I have also tried doing it via tftp without luck.

    Any suggestions on what I could do would be useful. I have a feeling that the router has a hardware issue given the inability to ping the interface.

    Thank you

    It seems that is problem with autonegotiation of 1000/100 mbit networks. Set the router to recovery mode, next connect to the computer as described on ASUS web pages (network computer port address 192.168.1.2/24 or DHCP), disable the computer wi-fi, reboot the computer still connected to the router using cable, al least, after reboot, start the ASUS firmware recovery utility again, select the proper firmware file and start upload...
