Installation on RT-AX53U

I’m currently learning how to do this setup on a router for the first time. Working on an ASUS RT-AX53U and struggling with finding a way to transfer the binary file to the router from my computer. I’m unable to connect to the router over Ethernet on Ubuntu, so I’ve had to work in Windows. Unfortunately, I can’t access the router while it’s connected to internet, so I can’t download the firmware directly. I can’t use the cat command since I’m on Windows, and I can’t use the scp command since Asus have removed support for it on their firmware. So, I’m stuck.
Any tips? Thanks.

This sounds rather unusual. Probably a configuration issue with the Ubuntu machine.

What exactly do you mean by this? Are you connecting to the router's lan port (ethernet)? If so, you should be able to reach the router itself without issue.

Did you follow the directions here:

Yeah, some hardware issues that I need to fix.

I’m able to connect to the router via the LAN port without issue. I’m using the router in Access Point mode, so that it’s connected via another LAN port to the primary router. It’s when I connect the two routers together that I lose connection between my computer and the AX53U.

Yeah, that’s the page I’ve been following.

If you want to install OpenWrt, the best option will be to start with the device in a fully reset/default state. This should make it a router. Then connect a cable between the wan port of the AX53U and the lan port of your main router. If your main router and this device happen to have the same LAN IP addresses/subnets, one of them will need to be changed. Once that is done, you should be able to follow the rest of the directions by connecting your computer to the LAN of the AX53U.

Thanks, it was smooth sailing after doing as you instructed

There is a very high probability that you can flash OpenWRT firmware on this device using only the AsusWRT WEB-interface.
All the tools are already ready: https://github.com/openwrt/firmware-utils/pull/19
All that remains is to find a very trained tester who has such a device.

I have such a device and am ready to test. Cannot flash over ssh with mtd-write for some reason - keeps booting to the asus firmware.

Can you "hold my hand"? From what I can see the code is not committed? PM me with some info and I'll test it.
