DHCP Service with Router Model SBE1V1K

Thm1234

I am using the Spectrum Issued WIfi7 router model SBE1V1K.

I have DHCP enabled, and all devices on my network are getting the network configuration this way. Now, one machine was at 192.168.1.77, and I have several services running there. It's crucial that this stays the same, and reservation and port mappings stay the same. However, somehow the router forgot about this and gave the machine a new IP address. So I reconfigured and hardcoded 77 and rebooted, bit the machine and the router, and so we are back in business, except the router will not recognize that a 192.168.1.77 is on the network and won't allow me to make a reservation or map any ports to that IP. How can I enter such a reservation and port mapping, or make the router recognize that device, so I can make a reservation?

Thanks./

I doubt it but one thing you could try would be to stick with DHCP for the machine then reserve the IP address and then see if the IP address of the reservation can be edited and then re-up the machine's DHCP. Otherwise i think one silver lining about routers that don't facilitate that is how much ARP chatter is eliminated from your LAN if you just stick with DHCP and reserve whatever IP address the machine gets.

Correction/update: @Thm1234 :

1. Forget what i said about ARP chatter. My bad! I'm a moron.
2. Check out this story from somebody who apparently does know what they're talking about:
