Devices lose connection to Orbi RBK13

[Georgepy]

I can set up my Orbi RBK13 and get wifi connection. But, devices will lose a connection and will not reconnect automatically or manually. It gives the message couldn't find IP address.

I thought the problem might be my modem was too old. So, I upgraded to a Netgear CM1200.

This set up worked for about 48 hours. Now it has lost connection, again! I have restarted the modem. Doing a new set up I was able to reconnect. Is there anything I can do to avoid going through this daily?

First, how technical are you? Second, are you able to log onto the Orbi from any device, by any means (wired, wireless, web interface, Orbi app)?

Do you understand DHCP and static IP addresses? Do you have access control enabled on your Orbi? If so, is it set to block or allow new devices by default? Is your problem limited to just a particular device, or all your devices?
