I have an existing RBK50 setup with 2 RBS50 satellites connecting via wireless to the RBR50, this setup is working great, but because of working from home, i've had to set up a home office in the basement (long story... kids took over the real study) I recently got an additional RBS50 to place in the basement, and was plannign to use ethernet backhaul to try and get the best connectivity in the basement. I read on this community that a mix of eithernet and wireless backhaul works, so this is what i did.

First, firmware is V2.5.1.8 on all the devices. RBK50 is running AP mode. My router is a Ubiquiti Edgerouter-X with dual WAN load balancing (both WANs are each max 500Mbps, fast.com average gets 400-450Mbps on ethernet). I'm using the web UI, but also the mobile app (as the mobile app seems to show a little more information, eg. it is supposed to show the ethernet backhaul as a solid line...) So here goes..

I first set up the RBS50 in the basement as a wireless mesh, daisy chain on RBK50 is turned on, everything syncs up fine, seems to work fine - i get around 150-200 Mbps on fast.com. WebUI shows all 3 satellites with good connections on 5Ghz. All satellites and router in AP mode have reserved IP addresses on the Ubiquiti
After this is working, i plugged in an ethernet cable from a switch (Netgear managed GS908) to the RBS50. The satellite first went magenta, then seemed to work. However, the webUI still shows connected with 5Ghz, it doesn't show wired. On the mobile UI, it was weirder... The basement satellite was seen as connecting to another satellite in the main floor, which was connecting to the main RBK50...
So i went to turn off daisy chain, and it rebooted everything... but to make it more confusing, the mobile app shows magenta state and still dotted line (wireless) To make this worse, when you tap on the mobile app to the magenra satellite, you dont' see any devices connected to them, they seem to be connecting to some of the other satellites (it's random!) Fast.com speed tests on the devices in the basement all have not showed improvement - still 150-200Mbps, but they also now have occassional drops to 50-80Mbps once in a while, for no reason.

As such, i've sinced removed the ethernet cable to the basement satellite, and is living with what it provide. That said, i'm curious why this is not working right? Any advice here? It sounds like this is a scenario that should have just worked.

thanks.
