The download link works for me, but it seems like ASUS' support page removed this firmware entry. Maybe it's unstable?

I wasn't saying otherwise. The download is fast enough for even an expert to miss.
Makes no nevermind, the page is 404 to me now.

Wow, I take this is an example of how long Asus supports their popular routers. I'm really impressed, been a few years (~13 years) since this one was released. Glad to be using Asus routers.

So it appears this firmware 3.0.0.4.382_52745 was released by accident or has proved to be unstable on the RT-N66U's hardware & will not be re-released?

ASUS have advised on their website that firmware 3.0.0.4.382_52734 would be the last, the RT-AC66U shares the same firmware revision number as the RT-N66U as the RT-AC66U 3.0.0.4.382_52745 firmware is still active & hasn't been removed on ASUS' website?

One is a 802.11n device, the other a 802.11ac device, different hardware, different chips, for sure different firmware.

Sure I understand that it's a completely different hardware platform 802.11n vs 802.11ac, I forgot to mention the RT-N66U shares the same firmware revision number 3.0.0.4.382_52745 as the RT-AC66U.
