Orbi - sometimes no data after switching to router mode

Hi all,

I have a RBR40 with two RBW30 wall sattelites. Untill recent I used them in AP mode with no problems. Due to a change in provider/modem I now use it as Router with my internet connection on the RBR40. This works fine, but sometimes (every so much minutes) no data seems to be passing via wifi. Cable connections do not seem to be affected, but not sure.

Speedtest shows my exact speed, no problem there. WHen the connection is fine, the speed and connection are also fine.

Have a mix of android, IOS, WIndows and other devices.

Firmware:

RBR40 V2.3.5.30

RBW30 V2.3.5.6

I have the follwing settings:

2.4

Enable 20/40 MHz Coexistence enabled

Enable WMM (Wi-Fi multimedia) settings enabled

5

Enable WMM (Wi-Fi multimedia) settings enabled

ALso tested with WMM disabled.

Daisy chain disabled

Enable Implicit BEAMFORMING enabled (also tested with this disabled)

Enable MU-MIMO enabled (also tested with this disabled)

Fast roaming disabled

After the firmware upgrade to 2.3 and before swiching to Router mode I did a factory reset of all three components.

Any ideas

Thanks!
