So I downloaded the upgrade-2.4.0.bin from the wifi pineapple website. Now it is on my computer. How do I install it to my pineapple. Do I have to put the bin file onto the microSD card and press a button on the web interface? Thanks for the help. PS: I wasn't able to connect my pineapple to a wifi access point because the only one I can connect to with my laptop or phone is enterprise security not wpa2 so I need a username, which the login interface doesn't have a spot for.
