RAX20, issues with DHCP... some devices losing their IP after a couple of days
Hello, I'm facing an annoying issue with my RAX20 router. Once every few days, some of the devices (a Samsung TV and the three Mitsubishi air conditioning units) lose permanently their IPs and even...

Has a factory reset and setup from scratch been performed since last FW update? A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch with a wired PC and web browser. Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.

For for mobile devices be sure that any MAC Address randomizer is disabled while at home:
Set up some IP address reservations as well for other devices:

Hi,
I didn't apply a factory reset, thank you for the suggestion: I'll try it.
One importan thing that I forgot to mention in the original post...
The RAX20 router is currently releaseing addresses in the 10.0.0.x subnet (if I remember well, this was suggested as the default when I first setup the router).
My home modem is releasing addresses in the 192.168.1.x subnet.
The two devices use two ddifferent SSIDs and I need to have both Wifi networks enabled (they cover different areas in my house.
I'm definitely not a networking expert, but I fear that if I set both the modem and the RAX to issue addresses on 192.1.68.1.x (both with their respective DHCP servers) this might create conflicts.... or will the fact that I'll use different SSIDs avoid any problem?

If your seeing 10.xomething on the LAN side then the RAX is connected to something upstream that is already using 192.168.1.1 and the RAX will see this and avoid it by auto changing to 10.something.
What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Yes FURRYe38, this is exactly my situation. To recap:
- The home modem is connected to my FTTH link.
- The modem is manufactured by ZTE, it has been provided by my ISP provider (Fastweb, an Italian company, I'm living in Italy)
- The modem has DHCP enabled and issues addressess starting from 192.168.1.50
- The RAX20 is connected to the modem via Wifi, it receives the 192.168.1.51
- The RAX20 has DHCP enabled and issues addresses in the 10.0.0.x range to all connected devices (inlcludes those that are repeatedly "losing their IPs" and failing to reconnect).
