Problems switching in Mesh
Since two years I have a setup with one router (RBR850) and three satellites (RBS850). All satellites are wired to the router. This should be set up as a mesh network, so that my devices automatical...

Can you provide more detail about this phenomenon?
Does this situation happen when moving around on one floor of the house, or when moving between floors?
- This happens when I move from ground floor to 1st or the other way around.
Only floor where I have two is ground floor. Where I have my router wired to my internet provider router (in a closet near frontdoor), and a satellite in the area we live.
One thing that might be worth mentioning, is that when I move between these floors I will pass the router. So maybe it’s causing issues that it goes from satellite, to router and to the other satellite within 15 seconds.Please give feedback to the question presented so we can better help you and get a better idea of what you have setup.

Setting up to test Orbi roaming on RBR50. (Sorry, it's the only Orbi I have with both router and satellite.)
Had forgotten how busy WiFi is. Geez. When a WiFi device broadcasts a Probe Request on a 5G channel, every WiFi access point on the same channel responds from both the primary and the guest WiFi SSIDs, including an RBR750 that is used to "test things" and all the neighbor WiFi's that are also set to channel 48.
Anyway, after powering off the RBR750 and disabling Guest WiFi, experiment 1 was (almost) successful:
- Configure WiFi adapter in monitor mode, channel 48.
- Open Wireshark using WiFi adapter and capture only packets with the MAC address for Sony phone.
- Enable WiFi on Sony phone.
- Wireshark capture clearly shows:
- Phone broadcasts a Probe request.(with a bewildering number of settings!)
- Orbi router and satellite respond with Probe Response.
- Phone sends Authentication Request
- Router sends Authentication Response
- Phone sends Association Request
- Router sends Association Response
- Walk downstairs and stand close to Orbi satellite. Wireshark capture shows
- Phone sending Probe Request
- Orbi units sending Probe Response
- Phone sending Authentication
- Orbi sending Authentication Response
- Phone sending Reassociation
- Satellite sending Reassociation Response
- Phone continues to send Probe requests all the time. (another experiment would be to capture for an extended length of time and see how often the phone "looks around"
- One of the Orbi satellites continues to response that the Guest network is available, when it was clearly disabled. (WTF? People who complain that guest network behaves strangely may have a valid point!)
- Unfortunately, this Wireshark experiment did not capture the phone reconnecting to the router when it returned upstairs. (darn! Closed the capture too soon?)
Is there a point to this rambling narrative?
Yes. There is clear evidence that:
- Some WiFi devices continue to broadcast Probes asking "What WiFi Access Points are here?"
- When a mobile device moves from one Orbi WiFi access point to another, it will Reassociate with the stronger signal.
The hypothesis remains the same. When the iPhone moves between floors, the Orbi WiFi signal falls off so suddenly that the phone decides to change to LTE data before it finds a WiFi signal and this causes it to lose connection with the LAN subnet.
How to document this hypothesis is unknown.
