R3 suddenly disconnects, I'm thinking of dropping R3 and keeping the ISP; I'm desperate.

Hi, I keep getting disconnections with the R3. My router is connected to the ISP and the R3 is in DMZ on the ISP's router. I'm trying to assign a DHCP IP address, but I can't because the ISP's router doesn't appear in my devices on the R3. Here's the changelog.

You would assign a reserved/static address on the ISP router for the R3, not the other way around as the R3 is connected to the ISP router. 

Go to Settings > DHCP > Add Rule > Select a device and save, repeat for all your devices. Also in DHCP settings set the lease to 10,000. Make those changes, reboot the router from the interface, close the interface, wait 4 minutes and see if it happens again.
