Wifi connectivity issues

Question

Hi,&nbsp;I have a setup with&nbsp;RBR850 and two RBS850 satellites with the latest firmware installed. RBR850 is located in the basement and is connected to an unmanaged Netgear switch. The switch is connected to 5 RJ45 sockets across the house plus some devices. On the 1st floor, one RJ45 socket is connected to an unamanged Netgear switch. That switch is connected to a RBS850 satellite and some devices. The other satellite is connected to another RJ45 socket on the 2nd floor.&nbsp;I have connected approx 45 devices, many via ethernet and 5 ghz. I have Ring devices that use 2.4 and 10 Sonos players plus one hardwired Sonos Boost (which creates a dedicated wifi for the players). Sonos players are listed as wired devices on Orbi.&nbsp;If devices are connected, they show a good wifi connection. However, devices randomly drop the connection. If I try to reconnect them, I get the connected checkmark next to the wifi name, but the device does not receive an IP (shows 169...). It usually takes 30 - 60 seconds and many wifi turn on / offs before the devices finally receives the IP. It doesn't look like the wifi is down because all the other devices remain connected to the WIFI &amp; Internet.&nbsp;I did a factory reset, changed the positions, nothing worked. Logfiles do not really provide any useful information.&nbsp;Any pointers would be much appreciated.

Switched modem to router and Orbi to AP mode - which did not help. Looks like either the switches or the ethernet-connected devices&nbsp; are the cause.&nbsp;I separated now my Orbi from the switches by connecting it directly to the modem. Orbi satellites are still connected via ethernet but without switches or any ethernet-connected devices. Those are also connect to the modem. At a first glance, it feels like an improvement.&nbsp;Two questions:1) What if it still takes ages here and there to connect to the wifi? Could it be a hardware issue?2) Is there an efficient way to identify the culprit device that causes the initial problem? Not a big fan of disconnecting everything for days and then slowly connecting items one by one.

What modem/gateway is the router connected to?&nbsp;
What actual model switches is it?

Modem is the sunrise connect box 2 (cable modem in Switzerland) , running in bridge mode. Internet is pretty solid.Switch in basement: Netgear&nbsp;GS316P-100PES (16 Ports)Switch on 1st floor: Netgear GS108GE (8 Ports)

I've seen a few gateway's that struggle in bridge mode.&nbsp;
Try putting it in router mode (disable its wifi) and connect the orbi in ap mode.&nbsp;
Maybe its the gateway not renewing leases or causing issues with dhcp

It shouldn't take ages to connect to the wifi.&nbsp;
but in ap mode, the ISP device managed the IP assignments so that can create the occasional slowdown.&nbsp;
&nbsp;
There isn't an easy way to troubleshoot. I usually tell people to start simple. Meaning start at just the modem/router and use those. Then add in a satellite. then power the satellite off and add the other one in. About the only way to tell which device is causing issues is to see when the slowdowns occur.&nbsp;
