Hello, I'm having an issue with the router as it will disconnect all devices from the internet.
I increased the DHCP lease time to 1 week and all was ok until that week hit then I had to manually press the reset button on the back which made the interface accessible again but about a day later and no device was connected to the internet again.
My setup is ONT - NETDUMA R3 via pppoe
im on firmware version 4.0.290
PS5 in DMZ if that makes any difference at all
Thanks!
