IP Address Reservation is not working after upgrade to FW 20200727 Rel. 37987 on Deco M4
I have my deco for awhile and so far the address reservation is working just fine. But recently I have ask to upgrade to FW 20200727 Rel. 37987 (latest) then today my home power went down and after power is back all the IP address are messed. I look into each device IP address and all wrong assigned not according to the address reservation.
I try remove all addresss reservation and re-added it and reboot router many time without success.
Anyone having this problem and how to slove it?
