Losing internet every 10 days or so with Telus ISP and RT-AX86U (Merlin 3004.388.8_4)

Can't have two devices with the same IP on the same network.

You can if one only responds to a specific port and intercepts packet

Try giving the same IP to two of your clients and see the result.

Routers run better if you reboot them everyday. You can setup your router to reboot everyday at 4am in the ASUS UI.

I have gone as far as purchased a Meross Smart Plugs that turns my routers off at 4:00am and back on at 4:01am.

I also purchased a notebook fan for my routers that reduce the router temperature by 15c hence my network runs super smooth everyday.

Not doing that, other things can "break", rather than this its better to solve the underlying issue that would make a reboot necessary in my opinion...
