Subnet conflicts and timeouts on RV

I've got the GL.iNet GL-MT1300 (Beryl). I'm using it in place of the router that comes with my RV. The router that comes with the RV locks you in on either not having Wi-Fi or paying for their internet plans.

I've always had 2 problems:

1. When using the OneConnect app (the android app that interfaces with the RV through the router), it seems like there is a constant timeout that happens once a minute where everything goes offline and then reconnects. Wifi still shows as connected the whole time.

I'm not sure anything can be done about it as I don't know if it's something with the router settings or if its the RV gateway that is hiccuping because of incompatibility from expecting a different router. Any ideas of how to diagnose this or at least to figure out if it's the router that's causing this? (maybe some security thing or some way it's handling traffic routing?)

2. Occasionally, I can't get connected to a wifi at an RV park. I'm never sure why. Every other hardware I have can connect but not this. It connects and doesn't give me internet or it tries to connect and just drops.

I may have an idea of what could be causing this. I never had visible errors, but I just updated the firmware from the old 3.x to the new OpenWRT 4.x based one. After connecting to my home WIFI..... Everything works but I see an error that says "LAN subnet is in conflict with the WAN subne, Please Change Lan Subnet to a different address’’.

I'm not sure why everything works if I get that error, but it does. What I wonder is if there is a quirk in why it still works on mine when it encounters this issue but not on others.

I can't change the router's IP address of 192.168.1.2 because I have to use the exact one as the factory router for it to interface and work with the RV. This also means I can't change the Subnet start/end to resolve the conflict.

Any suggestions?

Sorry waht is this? Can you explain more?

First, you can try op24 firmware GL.iNet download center
Whatever the reason, this op24 firmware should be better.

Second for your subnet confict I am not sure what you mean. Should just be as simple as changing a subnet without causing problems.

The router's LAN IP is 192.168.8.1 by default. Did you change this one?

To 1:
Maybe this is an Android issue.

Android detects there is no Internet at WLAN and switches to mobile network, until you have connected your router to a WAN...

Solution: disable mobile data in your phone, configure your router per app or admin portal and enable mobile data...
Very odd, but GL-l.iNet can not help, when the phone won't route 192.168.8.1 to the matching device, even if it is direct connected.

I've tried airplane mode, so that doesn't effect things.

I DID change the default 192.168.8.1 to 192.168.1.2 . As mentioned, I HAD TO for it to work.

So my question is what happens when there is this subnet discrepancy and why does it still work. Even if internet still does work, will there be other issues that crop up?

"LAN subnet is in conflict with the WAN subnet, Please Change Lan Subnet to a different address’’.
