Hi Everyone , we have an oc300 omada controller and we are applying a mac address allow list for some ssid, and it was working mostly fine and until we wanted to remove mobile devices and i copied and pasted the group to excel removed the mobile devices and reimported the group , and it was working fine but because of electricity problem we had to turnoff the power and when i turned it on the next day i noticed that , all the users were getting rejected , so i imported the group again and applied it to the ssid's and it worked for the day but there is a power problem in our office and we are running on a generator so we must switch off every day , so this problem happens every time we switch off the devises because of power problems , and the only temporary fix i have for this is reimporting the mac address groups every day from excel sheet. can anyone help me on this issue?
