Device disconnects from the internet (RE500 V1)

Installing and Using OpenWrt
1

After leaving my phone inactive for sometime, it disconnects itself from the internet (still connected to the wifi). I cannot access my main router during this time (192.168.1.1) but can access the extender I am connected to (192.168.1.2). I fix this temporarily by toggling the wifi setting off and then back on in my phone. I immediately gain access to the internet as well as the main router. This seems to happen only on WLAN. Ethernet seems to be fine as of now. I can't seem to find the reason in system logs, but when I turn off wifi on my phone it shows AP-STA-Disconnected. The system log when doing the reconnection:

Edit: This also happens on my other phone, both of them are iPhones (is this an iOS issue?)

I'm not an expert on the wds configuration elements, but I have noticed this:

the devices should not be specified here... the association between a network interface and the SSID must only be made in the wireless config file (with the option network in the wifi-iface definition). The wlan hardware should never be referenced in the network config file.

I myself have no clue on what I've done (new to OpenWRT). I wanted Network_5GHz through ethernet only (to my laptop) and the 2.4GHz through WLAN (for other devices like my phone). The configuration I have done was a trial and error till I got everything I wanted. Sadly it is the disconnection from the internet that I am facing when leaving my phone switched off for a while. I have made a backup so I am ready to modify whatever is needed. If I have to remove a device from a config, can I have a guide on modifying the configuration?

Edit: Here is what’s happening on my phone: https://streamable.com/s91tfj

I did a reset and restored the config from the backup made. Currently I haven't experienced any disconnections (hopefully not). I will update on this in a few days if the issue does not yet happen or if it does. Thank you!

Sadly the issue still persists. But just by toggling WiFi settings on my phone, I immediately gain access to the internet. I can't seem to find the root cause for this as logs aren't showing the part when the phone loses internet access. But toggling the WiFi off in the phone results in AP-STA-DISCONNECTED as expected, and does the opposite when toggling it back on.

I might have solved the issue by following the guide here. I guess I may have done the configuring wrong and basically this guide has a similar end result as my expectation (extending WiFi on areas with less coverage) but I did connect the extender to the router wirelessly. Regardless I will update if anything goes wrong. Thank you!
