unable to add shelly device to my home network

[mrrudedog1]

I am unable to add a Shelly1 smart device to my Orbi network. I have about 30 devices on the network that work fine. Shelly support believes that it is my local network that is the problem, as I can add the device onto my phone's hotspot network with no problems. I need the device (a small wifi relay) to be on my home network so that I may control it through Alexa.

Shelly support suggested on making a new 2.4ghz network, but I see nowhere in the Orbi setup that I can choose speeds. The network map shows devices connected to both speeds.

I can log onto the Shelly's wifi network and control the device from my phone or laptop, just can't add it to mine.

I don't see many configurable options in the orbi settings. I made a guest network and am unable to add the device to this either.

Latest firmware is installed I believe. v2.5.1.8 on orbi and my orbi satellite.

Any help appreciated.

Try this:

Log into the Orbi web interface (http://orbilogin.net)
Navigate to the Advanced Tab, Advanced Settings, Wireless Settings
Uncheck the box, "Broadcast SSID on 5G"
Click "Apply"
All devices that are currently connected to the Orbi will remain connected.
On the smartphone, go to wireless settings and "forget" the Orbi SSID
Search for available WiFi networks. Select the Orbi WiFi. Enter the password. and connect.
If you are curious about whether the smartphone is actually connected at 2.4G, you have to wait a few minutes, because the "Attached Devices" display takes a while to update.
Open the app and set up the 2.4G device.
Once the device is connected and working as it should, reverse the steps.
Check the "Broadcast" box and click "Apply"
"Forget" the Orbi WiFi. Search. Enter password. Connect.

Be aware that there seems to be a time limit with some iOS or Android devices that will connect to the 2.4Ghz radio for a short period of time before changing automatically to the 5Ghz SSID, even though it's been hidden. The SSID is hidden only, thus the signal is still present. So you might want to also change the power output of the 5Ghz radio to 25%. Then connect your mobile device at a distance from the RBR to ensure the mobile phone keeps connected to the 2.4Ghz radio. After you get the IoT device connected, re-configure the system back to where it was.

If your SmartPhone keeps connecting to the 5GHz band, then try moving further away from your router and satellite with the phone. The 2.4GHz signal has a longer range than 5GHz, but a slower bandwidth.  So if you are 50 feet or more away from the router/satellite,  your phone may change to the 2.4GHz signal.  Once it does, then do the setup of the IoT device.
