Hello,
I am not entirely sure if I needed a firmware upgrade since all was working ok, but when I attempted to upgrade the firmware on my MI424WR rev G router to to 4.0.16.1.56.0.10.11.6-MI424WR.rmt I got an bad file signatures error msg. I tried it several times and doublechecked I had the correct router model. Also, is this device supposed to be downloading and installing such updates by itself? Thank you.
