Nighthawk C7800

All of a sudden my router is randomly changing my IP reserved addresses.

 

I set them up under "advanced/setup/LAN setup" properly with MAC addresses and IP's.

Up until a few days ago it has worked for a very long time. 

I am now on version 6.01.07 and was recently upgraded from COMCAST.

Does this version have issues?

 

 I tried to change one again and it worked once and went from xxx.xxx.xxx.201 to xxx.xxx.xxx.4

 

What would be a good NEW router if I need one that has ACCESS CONTROL, at least dual band, and IP reserved addresses and that works with XFINITY/COMCAST?

    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. 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.
