No way to upload firmware

[JustinZ]

I bought a new AC66U B1 (my second) .. but this new Asus firmware doesn't seem to allow you to upload your own file...

Sorry if this been answered but I searched around and cant find any help

How do I upload custom firmware to this router?

There's no [Choose file] button, instead there is only the [Check] button...

So i was trying the [Upload] hyperlink under the Aimesh router section without success thinking it was specifically for Aimesh router stuff...

but... my issue was that I was trying upload the AC86U file (not AC68U)...

once i selected the correct file it uploaded fine
