RBR50 Firmware Update & Documentation

having issues with WiFi connectivity since updating the Orbi to 2.5.0.38

i see that there is a HotFix 2.5.0.40, per the docuemntation it states:

To manually update your satellite’s firmware:
1. Launch a web browser from a computer or mobile device that is connected to your
Orbi network.
2. Enter orbilogin.com.
A login window opens.
3. Enter the router admin user name and password.
The user name is admin. The password is the one that you specified the first time
that you logged in. The user name and password are case-sensitive.
The BASIC Home page displays.
4. Select ADVANCED > Administration > Firmware Update > Manual Update.
The Firmware Update page displays.
5. Select the check box next to your satellite’s model name.
6. Click the Update button.
The Orbi satellite Firmware Update window opens.

I dont see anywhere in the App Advanced > Administration.  Anyone else having issues?
