Rig Manager on IOS 26.0.1 stopped connecting to Profiler Player

This was working fine, but tonight, I cannot connect my iPad Pro 13" M4 to my Profiler Player running iPadOS 26.0.1 using Home Network Mode and Access Point Mode.

Both were working fine a couple of weeks ago. I didn't notice sooner because I usually run Rig Manager on my Android devices (which are both working fine)

The only thing that (might have changed) was an update from iPadOS 26.0.0 to iPadOS 26.0.1. I don't recall if I've tried to run Rig Manager on the iPad since that update.

Player is upgraded to Level 3.

Versions - Rig Manager

Android 13.0.5.61298
and

iPadOS 13.0.5.61298

I tried uninstalling Rig Manager on the iPad and then reinstalling it. This made no difference. Neither has restarting the iPad (power down/up).

I also cleared the wireless settings on the Profiler Player (Long long press on the WiFi button).

A second question. (when everything was working on iPad and Android)
In the Home Network Mode, I can only connect using a 2.4 GHz home network, not 5.0. I didn't see any mention of this in the documentation.

Thanks for any suggestions.

I've also submitted a message to Kemper Support.

That's correct.

KEMPER PROFILER Player Main Manual 13.0 (English) says it in the Technical Specification section

Code

2.4 GHz and WPA2 PSK

Thanks, I guess I missed it.
