Archer A6 Access Point mode unstable
I have my ISP modem HG8145V5 in my living room.
I have my Archer A6 in another room, that I've been using as an extender.
For some months now, I've used it in Router Mode and has given me no issues.
But I need all the devices in my network to reach each other, so 2 days ago I changed it to Access Point mode (it doesn't have Bridge mode).
I configured the 2.4 and the 5g wifi networks with the same credentials as the network on my modem, and devices can connect and see each other on the network.
DHCP is enabled on my HG8145V5 modem.
It is disabled (grayed-out) on my Archer A6 when in Access Point mode (I think this is expected for obvious reasons) .
However, the issue I've had since the 11th is that devices connected directly to the Archer A6 router suddenly lose internet access.
They seem to still be connected to the network, but they don't have Internet connectivity.
Some devices I have on it are a Desktop PC (ethernet), a laptop (wifi) and my phone (wifi).
When checking the ipconfig on CMD, it showed an empty string on the Default Gateway space.
When trying to use Windows assistant to fix it, it shows:
"Ethernet doesn't have a valid IP config"
The only way to restore this is to reboot the Archer A6, and devices will connect normally for some time until it happens again.
It doesn't occur at any specific interval, could be minutes or hours.
The devices connected directly to the ISP modem are not affected, only those connected to the TP-Link.
I was suspecting a possible firmware issue so I updated into the latest one, but it persists.
I decided to go back to Router Mode and the problem still occurred (it hadn't occurred in the past).
The Diagnostic log from the 11th shows the following:

For reference, C0A86409 (192.168.100.9) is my PC's IP.
I found the following post in the forum:
https://community.tp-link.com/us/home/forum/topic/226700
Which suggests not using Access Point mode, but that workaround is not viable for me because as mentioned, I need all my devices to communicate directly with each other.
Is there something you'd recommend to me?
As at this point I'm not sure if my Archer A6 could be faulty.
