Dear Friends. I have on my router the v384.4_2 alreasy installed. I downloaded the latest version for my router, tha is 384.5_0. When I tried to upload the file give me an error saying INVALID FIRMWARE UPLOAD. The comment goes as if there were an image error or error in the transmission. To make sure, I download the firmware twice from the Asuswrt-Merlin website. Why it does not work?
