Orbi RBR850 I can no longer add devices, can anyone suggest what I can do?

[drinkfairy1]

Unable to add devices to network, any suggestions on what to do?  I have the Orbi RBR850 with 1 satelite. It is attached to a modem for fiber optics.  This just started a couple of days ago, I had no problems before.

More detail would help.

When Network Settings on a device is opened:

• Does the WiFi network appear as one of the choices?
• When the WiFi password is entered, what happens?

Are there any devices which can be connected to the system with an ethernet cable?

My first thought is that Access Control has been enabled and the setting is to "not allow new devices to connect."

The way to determine is this is the case is to connect to the Orbi web interface (http://orbilogin.net) with the user name "admin" and the admin password (not the WiFi password). Then bring up the Attached Devices page.

At the top it should say that Access Control is on or off.

On the first try it shows no networks, then when I rescan it shows the network and when i try t connect it says unable, try again later. I have 85 devices connected, and these use to connect easily, I may uninstall the Kasa app and reinstall it to see what happens.

I had access control off, then turned it on and allow all to connect, that didn't work, so I turned it off again.

I may have made an invalid assumption.  (I often do.)

Does "adding devices" mean:

• No new WiFi device of any kind can connect to the system?
  (new phone, tablet, printer, .... anything), or
• The KASA app cannot add more devices?
  When I search for "Maximum devices on KASA app?", I get conflicting results.  One post from 2017 said there are "no limits" to the number of devices on KASA.  Another from 2021 talked about a limit in terms of KSAS Sense (whatever that is).

Thanks
