FPP 8.5.1 on Pi 4B LAN and WAN UI access is odd

[csmith]

3 identical Raspberry Pi 4Bs with 8GB RAM and 128GB SD cards.

Running latest FPP 8.5.1

One Pi set as master player and 2 as remotes.  All sync up and play fine together via dedicated wifi network.  Lights blink everywhere.

But...

When I try to log into any Pi wirelessly to check FPP, the connection times out.  On that Pi I can disconnect the data cable going to the controllers and then get in wirelessly to check FPP.  Plug the pixel controller data cable back into the Pi and wireless access disappears again.

Yet I know wireless is working because the 3 Pis are in perfect sync.

Frustrating.  Am I doing an unnatural act?

Here is how each Pi is configured:

Unit 1: Set as FPP Player
           etho set to static address 192.168.2.200, netmask 255.255.0.0 and gateway at 192.168.1.1
           wlan0  set to static address 192.168.2.201, netmask 255.255.0.0 and no gateway.  It logs into a dedicated wifi network

Unit 2: Set as FPP Remote
           etho set to static address 192.168.2.202, netmask 255.255.0.0 and gateway at 192.168.1.1
           wlan0  set to static address 192.168.2.203, netmask 255.255.0.0 and no gateway.  It logs into same dedicated wifi network

Unit 3: Set as FPP Remote
           etho set to static address 192.168.2.204, netmask 255.255.0.0 and gateway at 192.168.1.1
           wlan0  set to static address 192.168.2.205, netmask 255.255.0.0 and no gateway.  It logs into same dedicated wifi network

Any suggestions on what might be happening?

Something seems backwards here .. you want the gateway on the wifi side - the side that goes back to your pc/internet.
Normally this scenario has eth0 set to a different vlan ie ..not .2. from the wifi side.

Yes.
You do not want the Wi-Fi interface to be on the same subnet as the Ethernet interface, that can cause all kinds of problems.
This might help

I finally got this working. You're right. There are now two different subnets, and the gateway is set only on the wireless link.

What drove me nuts was that with FPP 8.5.1 (UI at the Advanced level), there are main and backup SSID settings to link to wireless networks. I entered details for both, and FPP would reboot at the oddest times when trying to change parameters. On a whim, I removed the settings for the backup wireless network, and suddenly, the clouds parted, the sun shone, and everything started working great.

Thanks for pointing me in the right direction.
