Who Me Too'd this solution

Avoid using the Orbi app for any FW updates. You can do this if you want to update FW:

I received an email that there was a Firmware update for my router. I tried to do it with the Netgear app but I received a Firmeware Check Error. I then downloaded the firmware to my laptop and read the instructions for installing. One place tells you to log into routerlogin.net and another place in the instructions specifies orbilogin.com. I tried both and attempted to login with username of admin and the password I set up when I installed the Orbi system. I get a 500 internal server error with both. Any suggestions?
