I have the Hitron Modem. I'm trying to add a computer to the Parental Control Managed Devices to set time limits.
I look for the computer on the Connected Devices and the MAC address is 12:CD:14:03:0A:D1
If I try to Add Managed Devices manually and enter this I receive an Invalid MAC Address message.
If I add the device using the Manage button next to the Connected Devices list, all seems to work until I hit the Save button, which make the setting disappear.
I tried this with any other device connected to my modem and it works perfectly fine, it only happens with this computer/MAC address.
Any ideas why the modem doesn't want to recognize this MAC Address?
