When I first got my Deco it had the default IP range as 192.168.68.0/24. I thought this was odd but I just rolled with it. The later an update came out and the address changed to 192.168.0.0/24. This was an issue because I have serval devices that have static IP addresses that I assigned (NAS, server) and a few wireless IOT devices that don't handle IP changes well. I made the changes and everything was fine. The the IP address range changed again, this time to 192.168.1.0/24. Once again I made the changes. Today I discovered that the IP range has changed yet again, this time back to 192.168.0.0/24.

Can any one tell me A. why my IP address keeps changing, and B. How can I stop it from changing again? Also annoying, it appears that I cannot change the range myself.
